Hosts:Pradip Kamat, Children's Healthcare of Atlanta/Emory University School of MedicineRahul Damania, Cleveland Clinic Children's HospitalIntroductionToday, we discuss the case of an 8-month-old infant with severe bronchospasm and abnormal blood gas. We'll delve into the epidemiology, pathophysiology, and evidence-based management of acute bronchiolitis.Case SummaryAn 8-month-old infant presented to the ER with decreased alertness following worsening work of breathing, preceded by URI symptoms. The infant was intubated and transferred to the PICU, testing positive for RSV. Initial blood gas showed 6.8/125/-4, and CXR revealed massive hyperinflation. Vitals: HR 180, BP 75/45, SPO2 92% on 100% FIO2, RR 12 (prior to intubation), now around 16 on the ventilator, afebrile.Discussion PointsEtiology & Pathogenesis: Bronchiolitis is primarily caused by RSV, with other viruses and bacteria playing a role. RSV bronchiolitis is the most common cause of hospitalization in infants, particularly in winter months. Immuno-pathology involves an unbalanced immune response and can lead to various extra-pulmonary manifestations.Diagnosis: Diagnosis is clinical, based on history and examination. Key signs include upper respiratory symptoms followed by lower respiratory distress. Blood gas, chest radiography, and viral testing are generally not recommended unless warranted by severe symptoms or clinical deterioration.Management Framework: For patients requiring PICU admission, focus on oxygenation and hydration. High-flow therapy and nasal continuous positive airway pressure (CPAP) can be used. Hydration and feeding support are crucial. Antibiotics, steroids, and bronchodilators are generally not recommended. Mechanical ventilation and ECMO may be necessary in severe cases.Immunoprophylaxis & Nosocomial Infection Prevention: Palivizumab and nirsevimab are used for RSV prevention in high-risk infants. Strict infection control measures, including hand hygiene and isolation, are essential to prevent nosocomial infections.ConclusionRSV bronchiolitis is a common and potentially severe respiratory illness in infants. Management focuses on supportive care, with a careful balance between oxygenation and hydration. Immunoprophylaxis and infection control are crucial in preventing the spread of the virus.Thank you for listening to our episode on acute bronchiolitis.

In this episode of PICU Doc On Call, Dr. Pradip Kamat and Dr. Rahul Damania discuss a case of a 4-year-old girl with bite marks and swelling of her foot, presenting with concerning vital signs and abnormal labs. They explore snake envenomation and its management in the pediatric critical care setting.Classifying Snake EnvenomationSnakes with venom-delivering fangs, primarily Elapidae and Viperidae, are responsible for most human envenomations and fatalities. We're focusing on Pit Vipers today, including rattlesnakes, cottonmouths, and the copperhead. Elapids, such as the coral snake, differ by having round pupils, short fangs, and no facial pit.Risk Factors for Pediatric SnakebitesSnakebite incidents can happen when toddlers unintentionally disturb snakes, particularly in low-light conditions or grassy areas. Teenagers trying to capture snakes are another frequent group presenting with upper extremity bites. Pathophysiology of Snake EnvenomationSnake venoms contain toxic proteins that affect various physiological systems, leading to neurotoxic, hemotoxic, myotoxic, or cytotoxic effects. Envenomation can happen immediately or be delayed, presenting with various clinical and laboratory anomalies.Syndromes Observed After Snake EnvenomationThe impact of a snakebite depends on the snake type, fang size, and venom injection site. Effects may include cytotoxicity, lymphatic system damage, platelet dysfunction, neurotoxicity, cardiotoxicity, hypotension, and nephrotoxicity.General Management FrameworkIn snakebite cases, prehospital care involves immediate EMS call and ensuring airway, breathing, and hemodynamic stability. In the hospital, general supportive care is crucial, and antivenin administration depends on clinical presentation and snake type.Antivenin ConsiderationsAntivenin dosage is challenging due to unknown venom load, and its choice depends on safety, kinetics, cost, and the specific snake involved. Smaller fragments of antivenin have larger distribution volumes and shorter half-lives. Recurrence, anaphylaxis, and serum sickness are potential side effects of antivenin.Clinical PearlsA high index of suspicion is required to diagnose snake envenomation.Antivenin is the mainstay of therapy, and rapid transport to a facility with antivenin is crucial.Patients should be educated about recurrence, serum sickness, and lifestyle adjustments after a pit viper bite.Thank you for listening to this episode on snake envenomation in the PICU.

PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode.In today's episode, we're bringing together some of the best content from our previous podcasts to present a comprehensive clinical case. We're also excited to share with you some of the most highly cited articles from the past year, presented in a practical, case-based format. This episode will offer you valuable insights into the latest research findings while also highlighting the real-world application of this knowledge in a clinical setting.We'll start by presenting an interesting case of a toddler who was transferred to the PICU due to increasing respiratory distress:A 2-year-old male was brought to the emergency department with a chief complaint of increased work of breathing and URI symptoms, including a cough and runny nose. The child had no significant past medical history, was not taking any medications, and had no known allergies. The child was up-to-date on immunizations, and there were no significant sick contacts.The family brought the child to the emergency department after noticing a significant increase in work of breathing, including the use of accessory muscles, nasal flaring, and chest retractions. The initial physical exam revealed tachypnea and decreased breath sounds on the right side. The child's vital signs were concerning for respiratory distress, with a heart rate of 170 beats per minute, respiratory rate of 50 breaths per minute, and oxygen saturation of 85% on room air. Chest X-ray revealed right lower lobe pneumonia.The child was started on supplemental oxygen, and broad-spectrum antibiotics, and trialed with albuterol. Despite initial treatment, the child's respiratory distress worsened, and the decision was made to transfer the child to the PICU and place the patient on HFNC 1.5 L/kg. Upon admission to the PICU, the child's vital signs were still concerning, he was afebrile, with a heart rate of 180 beats per minute, respiratory rate of 60 breaths per minute, and oxygen saturation of 85% on 1.5L/kg HFNC at 75% FiO2. Given the persistent respiratory distress, the decision was made to intubate the child in the PICU for acute hypoxemic respiratory failure. Shortly after intubation, a central line is placed in the R internal jugular vein.To summarize key elements from this case:2-year-old with a prodrome of URI symptomsIs otherwise previously healthy with no significant medical history or allergiesDeveloped respiratory distress and diagnosed with pneumoniaTransferred to PICU, intubated for respiratory failureLet's fast forward in the case and talk about a scenario that frequently arises in the PICU. It's hospital day 2, and the patient's RSV swab is positive, and we're seeing some improvement on the X-ray....

Today's episode of "PICU Doc On Call," with Dr. Pradip Kamat and Dr. Rahul Damania, pediatric ICU physicians, delves into intriguing case and management strategies within the acute care pediatric setting.This episode focuses on a 2-year-old child transferred to the PICU due to pneumonia-induced respiratory distress. As the child's condition deteriorates, intubation becomes necessary to address acute hypoxemic respiratory failure.We discuss the significance of minimizing unnecessary blood cultures in febrile patients with central lines in the PICU. A study implementing a quality improvement program is referenced, which successfully reduces blood culture rates, broad-spectrum antibiotic usage, and CLABSI rates without impacting mortality or length of stay.Next, we'll explore the comparison between a high-flow nasal cannula (HFNC) and continuous positive airway pressure (CPAP) in pediatric patients experiencing respiratory distress. Findings from a randomized controlled trial revealed that HFNC is non-inferior to CPAP in terms of time required for liberation from respiratory support.We further investigate the application of pediatric early warning scores (PEWS) and automated clinical prediction models to identify patients at risk of deterioration and transfer to the PICU. The importance of employing clinical judgment and a combination of assessment tools to determine the need for transfer is emphasized.Lastly, we'll highlight the significance of screening for social determinants of health in critically ill children and their families. A study demonstrates that a substantial number of participants had unmet social needs, underscoring the importance of screening to provide appropriate interventions and resources.To summarize, this podcast episode covers key topics such as reducing unnecessary blood cultures, comparing HFNC and CPAP in respiratory distress, utilizing PEWS and clinical prediction models for patient identification, and the importance of screening for social determinants of health.Be sure to listen in entirety as we discuss the case.

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists.I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine. I'm Rahul Damania from Cleveland Clinic Children's Hospital and we are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode.Today, we are going to discuss the management of the postoperative patient admitted to the PICU. Our discussion will focus on the non-cardiac and non-transplant admission. Our objective in this episode is to create a framework on what areas of care to focus on when you have a patient admitted to the PICU post-operatively. Each surgery and patient is unique; however, we hope that you will garner a few pearls in this discussion so you can be proactive.in your management. Without any further delay, let's get started with today's case:We begin with a 13-year-old child, Alexa, with h/o of a genetic syndrome, who presents today with a history of thoracolumbar kyphoscoliosis. Over the years, Alexa's curvature has progressively worsened, resulting in difficulty breathing and chronic back pain. The decision was made to proceed with a complex spinal surgery, including posterior spinal fusion and instrumentation.In the weeks leading up to the surgery, Alexa underwent a thorough preoperative evaluation, including consultations with specialists and relevant imaging studies. Pulmonary function tests revealed a restrictive lung pattern, while the echocardiogram showed no significant cardiac abnormalities. Preoperative labs, including CBC, electrolytes, and coagulation profile, were within normal limits.During the surgery, Alexa was closely monitored by the anesthesia team, who administered general anesthesia with endotracheal intubation. The surgery was performed by the pediatric neurosurgery and orthopedics, with intra-operative neuromonitoring to assess spinal cord function. The surgical team encountered an unexpected dural tear, which was repaired using sutures and a dural graft. Due to the prolonged surgical time, a temporary intra-operative loss of somatosensory evoked potentials was noted. However, signals were restored after adjusting the patient's position and optimizing blood pressure. The posterior spinal fusion and instrumentation were completed successfully, but the surgery lasted 8 hours. Total intra-operative blood loss was 800 mL, and Alex received 2 units of packed red blood cells and was on NE for a little over half the case before weaning off.Alexa was admitted to the PICU intubated and sedated for postoperative care. The initial assessment showed stable vital signs, with a systolic blood pressure of 100 mmHg, heart rate of 90 bpm, and oxygen saturation of 99% on mechanical ventilation. Postoperative pain was managed with a continuous morphine infusion. The surgical team placed a closed suction drain near the surgical site and a Foley catheter for urinary output monitoring. You are now at the bedside for OR to PICU handoff…To summarize key components from this case:This is a patient with thoracolumbar kyphoscoliosis, underwent complex spinal surgery (posterior spinal fusion and instrumentation) due to progressive curvature, breathing difficulties, and chronic pain.

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists.I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine and I'm Rahul Damania from Cleveland Clinic Children's Hospital. We are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode.Here's the case of a 12-week-old girl old who is limp and seizing presented by Rahul.Chief Complaint: A 12-week-old previously healthy female infant was found limp in her crib and developed generalized tonic-clonic seizures on the way to the hospital.History of Present Illness: The mother returned from work on a Saturday to find her daughter unresponsive in her crib. The infant had been left in the care of her mother's boyfriend, who stated that the daughter had been sleeping all day and had a small spit up. As the patient continued to have low appetite throughout the day and continued to be unresponsive in her crib, mother called EMS to bring her to the emergency department. En route, the patient had tonic movement that did not resolve with intranasal benzodiazepines.ED Course: The infant presents to the ED being masked. Upon arrival at the ED, the infant was in respiratory distress, with a heart rate of 190 beats per minute, respiratory rate of 50 breaths per minute, and oxygen saturation of 85% with bagging. She was intubated for seizure control upon arrival at the ED. Physical examination in the ED revealed bruising on the right neck region but was otherwise unremarkable. A non-contrast head CT showed no acute intracranial abnormalities. The initial diagnostic workup revealed normal CBC, mildly elevated hepatic enzymes, and pancreatic enzymes which were within normal limits. The blood gas showed metabolic acidemia with PCO2 in the 60s.Admission to PICU: Upon admission to the PICU, neurosurgery and trauma teams were consulted. A skeletal survey and ophthalmology consult for a fundoscopic examination were ordered, as there were concerns of non-accidental trauma. Further investigation is underway to determine the cause of the infant's condition.To summarize key elements from this case, this patient has:Patient left with mother's boyfriendInfant found limp and had seizures requiring intubationNeck bruiseAll of these bring up a concern for Non-Accidental Trauma (NAT) the topic of our discussion.Let's start with a short multiple-choice question:Which imaging modality is the most appropriate for establishing a diagnosis of abusive head trauma (AHT) in a 12-week-old infant with an open fontanelle on the exam?A. CT scan of the brain without contrast B. MRI of the brain without contrast C. Skull X-ray D. Doppler ultrasound of the headRahul, the correct answer is A. Though

We are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode:Welcome to our Episode about a 14-year-old male who collapsed on the baseball field.Here's the case presented by Rahul:A 14-year-old male athlete was playing in a high school baseball tournament when he was hit in the chest with a pitched ball. The impact caused him to collapse on the field. Bystander CPR was begun given his unresponsiveness and emergency medical services were immediately called. The patient was transported to the hospital. Upon arrival, he was unresponsive and had no pulse. An electrocardiogram (ECG) showed ventricular fibrillation, and advanced cardiac life support was initiated. After several shocks and cardiac compressions, the patient regained a pulse and was transferred to the pediatric intensive care unit for further evaluation and management.To summarize key elements from this case, this patient has:Been struck by a high-velocity object in the chestSuffered a cardiac arrest, likely due to an arrhythmia from the blunt chest traumaThe presentation brings up a concern for Commotio Cordis, our topic of discussion today!We wanted to create this educational episode in light of the recent medical event experienced by the Buffalo Bill's safety Damar Hamlin. His blunt chest trauma, which led to cardiac arrest, has been postulated to be due to commotio cordis. At the date of this record, we are glad that Damar Hamlin is on the road to recovery.Absolutely, let's dive in more into this topic, Let's start with a short multiple-choice question:The 14-year-old described in our case suffered cardiac arrest after blunt chest trauma. Based on the working diagnosis of comottio cordis, what is the most likely EKG finding which may be seen in this patient?A. Ventricular fibrillationB. Ventricular tachycardiaC. Complete heart blockD. AsystoleThe correct answer is A. In a study published in JAMA (2002; 287(9):1142-1146) which used data from the US Commotio Cordis registry maintained by the Minneapolis Heart Institute Foundation, reported that the most common arrhythmia out of the 128 confirmed cases, 82 of which had EKGs which could be analyzed was ventricular fibrillation. Three patients had Vtach, 3 had Bradyarrhythmia and 1 had complete heart block. Although 40 patients had asystole, this was unlikely to be the initial rhythm after impact. Interestingly, the majority of these rhythms were recorded at the scene.Rahul, What is the definition of Commotio...

Approach to Pediatric Trauma Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists.I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine and I'm Rahul Damania, from Cleveland Clinic Children's Hospital. We are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode.Welcome to our Episode today of a 7 yo M who presents to the PICU after a severe Motor Vehicle Accident.Here is the case presented by RahulA 7-year-old male child is admitted to the PICU after sustaining severe trauma. The patient was brought to the emergency department after a motor vehicle accident that involved an 18-wheeler truck & the family's car; in this severe accident the 7 yo was noted to be restrained however upon impact was ejected from the vehicle. He was unconscious and had multiple injuries, including a laceration on the head and bruising on the chest. The EMS was activated and the patient presented to the ED for acute stabilization. Upon examination, the patient was found to have a Glasgow Coma Scale score of 8, indicating a serious head injury. He had multiple bruises and abrasions on the chest and arms, and his pulse was rapid and weak. The patient was resuscitated with colloid and blood products, intubated, and transferred to the pediatric intensive care unit for further management.Notably, a CT scan of the head showed a skull fracture and a subdural hematoma. A chest X-ray showed multiple rib fractures and bilateral pulmonary opacities with no evidence of pneumothorax. The patient was also found to have a grade 2 liver laceration and a splenic injury. Pelvic x-ray and cardiac FAST exam were unrevealing.To summarize key elements from this case, this patient has:A traumatic brain injuryPulmonary contusions and is at risk for PARDSLiver and spleen injuryAnemiaPertinent negative includes: No pelvic injuries or injuries to great vessels in the chestRahul, let's approach the PICU medical management of this case based on a culmination of various guidelines published in the Pediatric Critical Care literature. Namely, let's use this case to dive deep into guidelines for:Traumatic brain injury (TBI)****Transfusion and Anemia Expertise Initiative (****TAXI)pediatric blunt liver and spleen injury management, are also known as the ATOMAC protocol, as well as general PICU management of acute trauma.As we take the management of this pediatric trauma patient in a systems-based fashion let's first go into the Management of Pediatric Traumatic Brain Injuries, can you start us off with some key management considerations?Based on the March 2019 TBI guidelines published in Pediatric Critical Care Medicine in 2019 (PCCM20(3S):p S1-S82, March 2019)This patient should have an ICP monitor or even an EVD placed for CSF diversion in consultation with the NS and trauma team. A CPP of at least >50 in our 7 yo patient and ICP < 20 mm Hg has been shown to improve outcomes and reduce mortality.Just as a quick review, CPP stands for cerebral perfusion pressure, which is the pressure that maintains blood flow to the brain. The formula for CPP is:CPP = MAP (mean arterial pressure) - ICP (intracranial pressure)Monitoring does not affect outcomes directly; rather the information from monitoring can be used to direct treatment decisions. Treatment informed by data from monitoring may result in better outcomes than treatment informed solely by data from clinical assessment. In short, it is important to have qualitative and quantitative data to optimize your decision-making.As we talked about ICP control is so crucial for

Dear Listeners & Peds ICU community, WE are back on air!Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists.I'm Pradip Kamat coming BACK to you from Children's Healthcare of Atlanta/Emory University School of Medicineand I'm Rahul Damania from Cleveland Clinic Children's Hospital and we are two Pediatric ICU physicians passionate about all things MED-ED in the PICU.PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting.As we turn into a new year, we would like to introduce Season 2 of PICU Doc on Call. Yes Pradip, I am super excited for this year & I want to take this moment to thank YOU all, our listener community for making PICU Doc on Call such a success as we share our passion for medical education thru this forum!This episode will give you a quick layout of how we will be organizing each episode of PICU doc on call this year. We will also highlight some tips and tricks on how to best learn from a medical podcast. Our goal in this episode is to provide you a framework on some best practices in medical podcasting and how to retain information from a podcast. Especially for our past & future episodes, we hope you can use this audio learning platform to assist you in applying the knowledge at the bedside when you are working in the acute care setting.Let's get into our first learning objective,Rahul, did you know that learning via podcasts can actually benefit your brain & change the neural chemistry.In fact, a 2016 med ed study published out of UC Berkeley concluded that listening to narrative stories from podcasts can stimulate multiple parts of your brain such as the limbic system and can enhance mood as it modulates dopamine and serotonin driven neural pathways. Think about listening to your favorite true-crime podcast — the suspense actually allows for you to stimulate centers in your medulla that increase the amount of endorphines, dopamine and serotonin that keep you on the edge of your seat.That is so unique, so based on this, I do want to highlight some of the key elements which will make our podcast or any medical podcast you listen to beneficial. These pearls will also help you if you are developing a medical podcast of your own!The first concept here is that many podcasts provide narratives.When it comes to medical podcasts, narratives are in the form of medical cases which allow for you to retain content knowledge as a patient case invokes emotion and this can help you remember information more robustly.When listening to a podcast, you have to use your imagination to picture what's going on. For example, if I painted a 2 yo M with a history of rhinorrhea at home for about a week who now presents to the ED with subcostal & intercostal retractions that then progresses to intubation in the PICU, you not only are envisioning a patient in front of you, but also are shifting your mind across settings. Our brain has to work at the pace of the audio, so hopefully your mind doesn't wander off like it does when reading a textbook page. And because you have to...

We are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: Welcome to our Episode a three-year-old girl with altered mental status and acute respiratory failure Here's the case presented by Rahul— A three-year-old presents to the PICU with altered mental status and difficulty breathing. Per the mother, the patient was in the usual state of health on the day prior to admission when the mother left her in the care of her maternal grandmother. When mom arrived home later in the afternoon, mom was unable to wake her and reported that she seemed "stiff". She did not have any abnormal movements or shaking episodes. Mom called 911 and the patient was brought to our ED. No known head trauma, though the patient is in the care of MGM throughout the day. No emesis. Nhttp://emesis.no/ (o) recent sick symptoms. No witnessed ingestion, however, the patient's mother reports that MGM is on multiple medications (Xarelto, zolpidem, Buspar, gabapentin, and acetaminophen) and uses THC-containing products specifically THC gummies. In the ED: The patient had waxing and waning mentation with decreased respiratory effort. GCS was recorded at 7. Arterial blood gas was performed showing an initial pH of 7.26/61/31/0. The patient was intubated for airway protection in the setting of likely ingestion. The patient has no allergies, immunizations are UTD. BP 112/52 (67) | Pulse 106 | Temp 36.2 °C (Tympanic) | Resp (!) 14 | Ht 68.5 cm | Wt 14.2 kg | SpO2 100% | BMI 30.26 kg/m² Physical exam was unremarkable-pupils were 4-5mm and sluggish. There was no rash, no e/o of trauma Initial CMP was normal with AG of 12, CBC was unremarkable, and Respiratory viral panel was negative. Serum toxicology was negative for acetaminophen, salicylates, and alcohol. Basic Urine drug screen was positive for THC To summarize key elements from this case, this patient has: Altered mental status: - waxing and waning with GCS less than 8 suggestive of decreased ventilatory effort pre-intubation impending acute respiratory failure Dilated but reactive pupils All of which brings up a concern for possible ingestion such as THC (but cannot rule out other ingestion) This episode will be organized… Pharmacology of Cannabis Clinical presentation of Cannabis toxicity Workup & management of Cannabis toxicity The Cannabis sativa plant contains over 500 chemical components called cannabinoids, which exert their psychoactive effect on specific receptors in the central nervous system and immune system. The 2 best-described cannabinoids are THC and cannabidiol (CBD)—and are the most commonly used for medical purposes. Patients with intractable epilepsy or chronic cancer pain may be using these drugs. THC is the active ingredient of the cannabis plant that is responsible for most symptoms of central nervous system intoxication. The term cannabis and the common name, marijuana, are often used interchangeably). Rahul, can you shed some light on the pharmacokinetics/pharmacodynamics of cannabis? Cannabis exists in various forms: marijuana (dried, crushed flower heads, and leaves), hashish (resin), and hash oil (concentrated resin extract), which can be smoked, inhaled, or ingested. THC is the active ingredient of the cannabis plant that is responsible for most symptoms of central nervous system intoxication, in contrast to CBD, the main non-psychoactive component of cannabis. The potency of cannabis is usually based on the THC content of the preparation. The THC is lipid soluble and highly protein bound and has a volume of distribution of 2.5 to 3.5...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine and I'm Rahul Damania from Cleveland Clinic Children's Hospital. We are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: Welcome to our Episode: A Somnolent Toddler. Here's the case: A 2 yo M presents to the PICU after being found increasingly sleepy throughout the day. The toddler is otherwise previously healthy and was noted to be in his normal state of health prior to today. The mother dropped the toddler off at his Grandmother's home early this morning. Grandmother states that he was playing throughout the day, and she noticed around lunchtime the toddler stumbles around and acts more sleepy. She states that this was around his nap time so she did not feel it was too out of the ordinary. The toddler 1 hr later was still very sleepy, and the grandmother noticed that the toddler had some shallow breathing. She called mother very concerned as she also found her purse open where she typically keeps her pills. The grandmother has a history of MI and afib as well as hypertension. She is prescribed a multitude of medications. Given the child's increased lethargy, the grandmother presents the patient to the ED. In the ED, the child is noted to be afebrile with HR 55 & RR of 18. His blood pressure is 78/40. On exam he has minimal reactivity to his pupils, he has shallow breathing and laying still on the bed. A POC glucose is 68 mg/dL. Acute resuscitation is begun and the patient presents to the PICU. To summarize key elements from this case, this patient has: Drowsiness Bradycardia Normotension This is in the setting of being at grandma's home and having access to many medications Given the hemodynamic findings and CNS obtundation, this patient's presentation brings up concern for a clonidine or beta-blocker ingestion. This episode will be organized: Beta-Blocker poisoning We will also examine other medications that potentially can be toxic to a toddler (one pill can kill) present in Grandma's purse which include: TCA, CCB, Opioids, oral anti-diabetic agents, digoxin, etc. The presence of a grandparent is a risk factor for unintentional pediatric exposure to pharmaceuticals commonly referred to as the Granny Syndrome. Grandparents' medications account for 10% to 20% of unintentional pediatric intoxications in the United States. To kids, all pills look like candy. Let's start with a multiple choice. An overdose of which of the following medications may mimic the presentation of Metoprolol overdose? A. Verapamil toxicity B. Ketamine toxicity C. Valium toxicity D. Lithium toxicity The correct answer is A, verapamil toxicity. Verapamil is a non DHP CCB. It acts at the level of the SA and AV node similar to Metoprolol, a beta-1-specific antagonist. Both cause bradycardia and AV node block. Valium though a CNS depressant, can cause CV depression as well, however, would have fewer changes on the conduction system compared to a non-DHP CCB.  What is the mechanism of toxicity with beta-blockers? Beta-blockers are competitive inhibitors at beta-adrenergic binding sites, which results in decreased production of intracellular cyclic adenosine monophosphate (cAMP) with a resultant blunting of multiple metabolic and cardiovascular effects of circulating catecholamines. They attenuate the effect of adrenergic catecholamines on the heart Decrease inotropic and chronotropic response. Some drugs like Propranolol can act as Na channel blockers (myocyte membrane stabilizing activity) at high doses resulting in arrhythmias and seizures. Toxic doses of drugs like Sotalol can result in K channel blockade giving rise to prolonged QT and risk for...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine and I'm Rahul Damania from Cleveland Clinic Children's Hospital and we are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: Welcome to our Episode of a 4-day-old with jaundice and vomiting. Here's the case presented by Rahul: A full-term 4-day-old boy presents to the ED after recently being discharged from the newborn nursery. Per mom, the patient "look yellow" and was having difficulty with feeding. The mother states that the patient would be increasingly sleepy, and will only latch to the breast for five minutes. The patient has been having decreased wet diapers, and the stool is loose and non-bloody. Mother was concerned today as the child continue to look yellow, especially in the eyes, had four episodes of vomiting, and overall was acting lethargic. The patient presented to the emergency room afebrile, tachypneic, and tachycardic. The patient was noted to have initial serum glucose of 70. As the patient was increasingly dehydrated, laboratory testing was difficult to obtain. The infant was fussy for the caregivers. The patient was resuscitated with 2 x 10 per kilo boluses and responded well. Point of care ultrasound noted normal four-chamber cardiac anatomy and squeeze. Given the instability of the patient, a RAM cannula was initiated, and the patient presented to the PICU. To summarize key elements from this case, this 4-day-old infant has: an acute presentation of jaundice and poor feeding Prominent GI symptoms and dehydration A sepsis-like presentation with hemodynamic instability responsive to fluids All of which brings up a concern for inborn error of metabolism, likely galactosemia. This episode will be organized… Clinical Presentation Laboratory Findings & Biochemistry Management of Galactosemia Rahul, let's start with a short multiple choice question: Of the following biochemical enzymes, which of the following is deficient in classic galactosemia? A. UDP Glucoronyl Transferase B. Aldolase B C. Galactose 1 Uridyl Transferase D. Galactokinase The correct answer is C. Galactose 1 Uridyl Transferase aka GALT. Classic galactosemia is caused by a complete deficiency of galactose-1-phosphate uridyl transferase (GALT). We should contrast this with galactokinase deficiency. These two present quite differently — GALT deficiency presents like our patient with jaundice, vomiting, hepatomegaly, renal dysfunction, and sepsis. Galactokinase deficiency has less of systemic symptoms and these patients similar to GALT deficiency have cataracts that are usually bilateral and resolved with dietary therapy. To go through our other answer choices, remember that Aldolase B is the rate-limiting enzyme in fructose metabolism, thus a deficiency in this enzyme would cause hereditary fructose intolerance. With this lead in question, let's pivot into the biochemistry of galactose and review key lab findings in our patient with galactosemia. Rahul, can you give us a quick summary of how galactose is metabolized in our body? Galactose is a sugar found primarily in human milk and milk products as part of the disaccharide lactose. Lactose is hydrolyzed to glucose and galactose by the intestinal enzyme lactase. The galactose then is converted to glucose for use as an energy source, however it needs a series of reactions: Galactokinase → which catalyzes the rxn galactose to galactose 1 PO4 Our rate limiting enzyme Galactose-1-phosphate uridyl transferase (GALT). GALT helps place a sugar moiety on galactose 1 PO4 to turn it into glucose 1 Phos which can then be utilized in glycolysis or glycogenesis. A complete deficiency in GALT is known as classic...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine. I'm Rahul Damania from Cleveland Clinic Children's Hospital and we are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: Here's the case presented by Rahul: A 21-month-old girl was brought to an OSH ED for somnolence and difficulty breathing, which developed after she accidentally ingested an unknown amount of liquid medicine that was used by her grandfather. Per the mother, the patient's grandfather was given the liquid medication for the treatment of his opioid addiction. The patient took some unknown amount from the open bottle that was left on the counter by the grandfather. Immediately after ingestion of the medicine, the patient initially became irritable and had some generalized pruritus. The patient subsequently became sleepy followed by difficulty breathing and her lips turned grey. The patient was rushed to an outside hospital ED for evaluation. OSH ED: The patient arrived unresponsive and blue, she was noted to be sleepy and difficult to arouse on arrival, with pinpoint pupils and hypoxic to 88%. , but After receiving Naloxone, however, she became awake and interactive. Her glucose on presentation was 58 mg/dL and Her initial VBG resulted 7.3/49.6/+2. She continued to have intermittent episodes of somnolence without apnea. Poison control called and recommend starting a naloxone infusion; she was also given dextrose bolus. The patient was admitted to the PICU. To summarize key elements from this case, this patient has: Accidental ingestion of an unknown medication Altered mental status Difficulty breathing—with grey lips suggestive of hypoventilation/hypoxia All of which brings up a concern for a toxidrome which is our topic of discussion for today The typical symptoms seen in our patient of pinpoint pupils, respiratory depression, and a decreased level of consciousness is known as the “opioid overdose triad” Given the history of opioid addiction in the grandfather, the liquid medicine given to him is most likely methadone.In fact, in this case, the mother brought the bottle of medicine, which was subsequently confirmed to be prescription methadone given to prevent opioid withdrawal in the grandfather.   To dive deeper into this episode, let's start with a multiple choice question: Which of the following opioids carries the greatest risk of QTc prolongation? A. Methadone B. Morphine C. Fentanyl D. Dilaudid The correct answer is methadone. Methadone prolongs QT interval due to its interactions with the cardiac potassium channel (KCNH2) and increases the risk for Torsades in a dose-dependent manner. Besides the effect on cardiac repolarization, methadone is also associated with the development of bradycardia mediated via its anticholinesterase properties and through its action as a calcium channel antagonist. Hypokalemia, hypocalcemia, hypomagnesemia, and concomitant use of other drugs belonging to the family of CYP3A4 system inhibitors such as erythromycin can prolong Qtc. Even in absence of these risk factors, methadone alone can prolong QTc.   Thanks for that, I think it is very important to involve your Pediatric Pharmacy team to also help with management as children may be concurrent qt prolonging meds. Rahul, what are some of the pharmacological and clinical features of methadone poisoning? Methadone is a synthetic opioid analgesic made of a racemic mixture of two enantiomers d-methadone and l-methadone. besides its action on mu and kappa receptors, it is also an NMDA receptor antagonist. Due to its long action, methadone is useful as an analgesic and to suppress opioid withdrawal symptoms (hence used for opioid...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine. Today we are joined by two wonderful clinical pharmacists — Whitney Moore & Stephanie Yasechko. Whitney is a Clinical Pharmacy Specialist at Children's Healthcare of Atlanta. She is on Twitter at @MoorephinRx. Stephanie is a Pediatric Lung Transplant Clinical Pharmacy Specialist at Cincinnati Children's Hospital Medical Center. We are so excited to have you both on today. My name is Rahul Damania and I am a Pediatric Intensivist at Cleveland Clinic Children's Hospital; Welcome to PICU Doc On Call where we focus on all things MED-ED in the PICU. Our podcast focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: Welcome to our Episode an 18 yo immunocompromised patient with headache & sore throat Here's the case presented by Rahul: An 18-year-old female (40 kg) with PMH significant for fibrolamellar carcinoma of the liver, presents to the ED with headache and sore throat. She is febrile to 38.3, tachycardic, tachypneic, and has a WBC of 27K on her CBC. She is markedly hypotensive with BP on the arrival of 99/65. Cultures were drawn, the patient was given x1 doses of vancomycin and meropenem, and she was transported to the PICU for further workup and management. Due to her progressive hemodynamic instability, increased inflammatory markers, and marked immunocompromised state, the team is considering broadening her anti-microbial coverage. To summarize key elements from this case, this patient has: Fibrolamellar carcinoma of the liver A presentation of headache, sore throat, and hemodynamic instability with concern for sepsis A current regimen of just antibacterials, which brings up the consideration of adding anti-fungal coverage in her clinically ill state. Our episode today will be covering anti-fungal agents in the PICU. We will review general mycology, understand different classes of antifungals, and highlight practical clinical pearls in the acute care setting. As mentioned, this patient has risk factors for an immunocompromised state due to her underlying liver condition. As we dive deeper into antifungals, Whitney, can you please give us an overview of common fungal pathogens in the PICU? Before we discuss the major drugs, it's important that we take some time to briefly review the most common fungi we encounter clinically since it's hard to choose the right agent when you don't know exactly what you are treating. Clinically, Candida is probably the most common fungal pathogen encountered, especially in warm, moist environments. It is important to determine what type of species is growing. The three major species known to cause infection are C. albicans, C. glabrata, and C. krusei, but it is important to differentiate these species when identified since they have different resistance patterns. Cryptococcus is another type of fungus that is known to cause meningitis or fungemia, especially in immunocompromised or cirrhotic patients. Both Candida and Cryptococcus are classified as yeast on Gram stain. Treating cryptococcus will require the use of an agent that has good penetration to the CNS. Endemic fungi known as Coccidia, Histoplasma, and Blastomyces are known to cause disseminated infections in immunocompromised hosts; however, each fungus is associated with a different geographic region in the United States. With any type of infection, it is always very important to consider your patients' exposures and recent travel history. And finally, there are two major molds that have the potential to be pathogenic. The first is Aspergillus which is identified via hyphae (tall filaments) on Gram stain well known to cause invasive pulmonary infections in the immunocompromised, specifically those who are neutropenic and/or received a lung transplant.

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine and I'm Rahul Damania from Cleveland Clinic Children's Hospital. We are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: Welcome to our Episode about a 4-year-old girl with a chief complaint of headache and vomiting Here's the case: A 4-year-old presents to the PICU with headaches + vomiting and abnormal CT scan findings. The patient presented to the ED with h/o abdominal pain X 5 days with nonbilious, non-bloody emesis. Initial CBC, UA was normal. The patient was given some pain meds and IV fluids. Further history revealed that the patient has been having severe headaches for the last 5 days and had emesis secondary to the headaches resulting in generalized, non-specific abdominal pain. No h/o of trauma or seizures, no h/o of fever or diarrhea, no h/o toxic ingestions h/o recent travel, exposure to sick contacts, COVID test negative. No family h/o migraines, her immunizations are UTD. Besides the normal UA and CBC, her CMP was also normal. A CT scan of the head revealed right frontoparietal mass with moderate surrounding edema, 6 mm leftward midline shift, diffuse sulcal narrowing, and right cisternal narrowing. Imaging of the abdomen (US and CT w/ contrast) was unremarkable. An MRI done revealed: Right parietal diffusion restricting lesion, most compatible with abscess. Moderate surrounding vasogenic edema. Given her abdominal pain- Abdominal KUB as well as contrast CT scan of abdomen and pelvis were performed and revealed no abdominopelvic pathology. In the ED her vitals were normal and the patient was afebrile. On her PE: the patient appeared sleepy but woke up and answered questions appropriately. No focal deficits, PERRL, normal tone and strength. The rest of her physical exam was completely normal. She now is transferred to the PICU for serial neurological exams. To summarize key elements from this case, this patient has: Headache with altered mental status No focal deficits Vomiting surprisingly no fever Imaging showing right frontoparietal mass. All of which brings up a concern for brain abscess This episode will be organized… Epidemiology and pathogenesis Diagnosis Management Rahul, can you inform our listeners about the epidemiology of brain abscesses? Only about 25% of brain abscesses occur in children. Incidence in developed countries is about 1-2% while in developing countries it's about 8%. Peak incidence in children is seen between the ages of 4-7 years and is more common in males. Brain abscess in the neonatal age group is rare but are associated with a higher risk of complications and mortality. Risk factors for brain abscess include Otologic infections (ear, sinus, and dental infections), Congenital heart disease (30% of patients with BA have an underlying heart defect) with intra-cardiac or intrapulmonary shunting (pulmonary AV malformations in hemorrhagic telangiectasis), immunodeficiencies (solid organ transplantation, HIV, etc), prolonged steroid use, diabetes, alcoholism neurosurgical procedures, trauma. Other rare causes can be airway foreign bodies, congenital dermal sinuses, and esophageal procedures (such as dilatations). Brain abscess typically begins with a localized area of cerebritis which evolves through various stages (typically 10-14 days) to develop into an encapsulated collection of purulent material with peripheral gliosis or fibrosis. 40-50% of the spread of infection is via a contiguous site of infection such as otitis, sinusitis or mastoiditis or from head trauma or neurosurgical procedure. 30-40% is spread through the hematogenous route from endocarditis, pulmonary infections, or dental abscess. 90% of brain...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine and I'm Rahul Damania from Cleveland Clinic Children's Hospital and we are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: Welcome to our Episode an 18 -year old with sore throat, and unilateral L-sided neck pain for ~2 weeks. Here's the case presented by Rahul: An 18-year-old female presents to the ED with cough, fever, fatigue, sore throat, and unilateral L-sided neck pain for ~2 weeks. The patient also has been having non-specific chest pain, weight loss, and decreased appetite for ~ 1 month. Patient has no recent travel h/o, no h/o of vaping or illicit drug use, and there were no sick contacts at home. Vitals revealed an HR 105, BP 116/66, Temp 38.3, and respiratory rate 35, She was 65 Kg and SPO2 on 2L NC was 100%. Physical exam was negative except (L) neck tender to palpation. There was no goiter, lymphadenopathy or hepatosplenomegaly. An initial chest x-ray was significant for possible multi-lobar pneumonia versus metastases. A Chest CT revealed multifocal septic emboli in the lungs. Echo did not show any gross vegetation. She has no rash or any trauma to the neck or difficulty swallowing, no oral ulcers, joint pain, or diarrhea. She had no recent dental work or drinking of unpasteurized milk or eating raw fish or meat. She was admitted to the PICU as she had hypotension requiring fluid boluses, and lab works significant for hyponatremia, rhabdomyolysis, worsening AKI, elevated ferritin, and elevated D-dimer. Her serum uric acid was 9.9, LDH = 230 (normal) ,ESR 78 (normal = 20 or less). Her serum lactate and serum troponin and BNP were all normal. Pertinently, US neck revealed an occlusive thrombus in the (L) IJ vein (done so as to avoid contrast in face of AKI), and blood cultures sent. To summarize key elements from this case, this 18-year-old female presents with fever +cough+sore throat Fatigue + Weight loss (L) neck pain Hypotension with abnormal labs including a concerning WBC with (L) shift, anemia, AKI, elevated uric acid, and ESR Chest CT with possible pulmonary emboli US showing occlusion. All of which brings up a concern for possible malignancy or pulmonary emboli from a septic focus in the neck and a possible diagnosis of Lemierre syndrome This episode will be organized… Definition Diagnosis (physical, laboratory) Management Rahul: What is the definition of Lemierre's syndrome? Lemierre's syndrome, also known as post-anginal septicemia or necrobacillosis, is characterized by bacteremia, internal jugular vein thrombophlebitis, and metastatic septic emboli secondary to acute pharyngeal infections. All of which are seen in our above case presentation. Previously called as the forgotten disease as its incidence was decreasing due to the increasing use of antibiotics especially penicillin for URI. However, recently there is an increase in Lemierre's disease cases with decreased use of antibiotics due to antibiotic stewardship. The recent increase in Lemierre disease due to decreased antibiotic use has not been proven and remain controversial. Rahul what are some of the causative organisms of Lemierre syndrome? The most common causative agent of Lemierre's syndrome is Fusobacterium necrophorum, followed by Fusobacterium nucleatum and anaerobic bacteria such as streptococci, staphylococci, and Klebsiella pneumoniae. Rahul: Can you tell our listeners about the pathophysiology of Lemierre's syndrome? Lemierre syndrome can occur in health adults (more common in males in the age group of 14-24 years). Risk factors include immunocompromised patients, organisms, and environmental conditions. Lipopolysaccharides in F. necrophorum have endotoxic...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. Welcome to our Episode a 16-year-old who is coughing up blood. Here's the case: A 16-year-old female with h/o SLE was transferred to the PICU due to hypoxia requiring increasing FIO2. A few hours prior to admission to the PICU patient also started coughing up blood and had difficulty breathing. The patient was admitted to the general pediatric floor 2 days earlier for pneumonia requiring an IV antibiotic and O2 via NC. Once transferred to the PICU, she had a rapid deterioration with progressive hematemesis, worsening respiratory distress, and saturations in the low 70s requiring escalating FIO2. The patient was emergently intubated using ketamine + fentanyl and rocuronium. Chest radiograph showed: Worsening bibasilar alveolar and interstitial airspace disease concerning pulmonary hemorrhage. The patient was initially placed on HFOV Paw 26, FIO2 70%, Hz 8, Dp 70, and later transitioned to airway pressure release ventilation or APRV. The patient was also started on inhaled tranexamic acid or TXA and high-dose pulse steroids. The patient initially continued to have some blood coming out from the ETT with suctioning but secretions became clear in ~24 hours. The mother reported that the patient has never had hematemesis/hemoptysis before, or bleeding from any site in the past. Denied history of frequent respiratory infections or recent URI symptoms. The patient has been vaccinated/boosted x3 vs covid. Her COVID PCR is negative. The mother states that she does not engage in tobacco products or alcohol. A physical exam revealed a well-developed teenage girl laying supine in bed deeply sedated and mechanically ventilated. There was decreased AE at lung bases and coarse breath sounds throughout. There was no hepatosplenomegaly and exams of the heart, abdomen and other systems were normal. There was no skin rash and extremities were well perfused with no clubbing in the fingers. The pulmonary team was consulted and a workup was started for pulmonary hemorrhage. To summarize key elements from this case, this patient has: Autoimmune disease: Systemic lupus erythematosus Respiratory Failure warranting MV 2/2 Pulmonary hemorrhage Her presentation and deterioration bring up a concern for diffuse alveolar hemorrhage our topic of discussion for today. This episode will be organized… Definition Etiology Pathophysiology Diagnosis Management Rahul: How do we define pulmonary hemorrhage (PH): PH is defined as the extravasation of blood into airways and/or lung parenchyma. Blood in the airways produces a diffusion barrier resulting in hypoxemia. Due to the reduction of airway diameter from accumulated blood, there is increased airway resistance and even airway obstruction. Subsequently, ventilation can be impaired leading to increased WOB as well as myocardial work required for O2 delivery. Repeated episodes of PH can result in interstitial fibrosis thus changing lung compliance. Hemoptysis by definition is any bleeding from below the vocal cords. PH can be classified as focal or diffuse. Diffuse is further classified as diffuse immune or diffuse nonimmune. Loss of 10% of a patient's circulating blood volume into the lungs, regardless of age, causes a significant alteration in cardiorespiratory function and should be considered massive. In adults, massive pulmonary hemorrhage is defined as blood loss of 600mL or more in 24 hours. In infants, the involvement of at least two pulmonary lobes by confluent foci of extravasated RBCs constitutes as massive PH. “Enough bleeding to make one nervous is probably massive.” Let's pivot and talk about etiologies. Pradip, What are some of the causes of pulmonary hemorrhage in the PICU? Non-immune diffuse PH is usually seen in patients with congenital heart disease (TAPVR, pulmonary atresia, mitral stenosis, hypoplastic left heart syndrome to name a few) neonates (secondary to sepsis, HIE, BW < 1500...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat coming to you from Children's Healthcare of Atlanta/Emory University School of Medicine and I'm Rahul Damania from Cleveland Clinic Children's Hospital. We are two Pediatric ICU physicians passionate about all things MED-ED in the PICU. PICU Doc on Call focuses on interesting PICU cases & management in the acute care pediatric setting so let's get into our episode: In today's episode, we discuss about a 12-year-old male with lethargy after ingestion. Here's the case presented by Rahul: A 12-year-old male is found unresponsive at home. He was previously well and has no relevant past medical history. The mother states that he was recently in an argument with his sister and thought he was going into his room to “have some space.” The mother noticed the patient was in his room for about 1 hour. After coming into the room she noticed him drooling, minimally responsive, and cold to the touch. The patient was noted to be moaning in pain pointing to his abdomen and breathing fast. Dark red vomitus was surrounding the patient. The mother called 911 as she was concerned about his neurological state. With 911 on the way, the mother noticed a set of empty vitamins next to the patient. She noted that these were the iron pills the patient's sister was on for anemia. EMS arrives for acute stabilization, and the patient is brought to the ED. En route, serum glucose was normal. The patient presents to the ED with hypothermia, tachycardia, tachypnea, and hypertension. His GCS is 8, he has poor peripheral perfusion and a diffusely tender abdomen. He continues to have hematemesis and is intubated for airway protection along with declining neurological status. After resuscitation, he presents to the Pediatric ICU. Upon intubation, an arterial blood gas is drawn. His pH is 7.22/34/110/-6 — serum HCO3 is 16, and his AG is elevated. To summarize key elements from this case, this patient has: Lethargy and unresponsiveness after acute ingestion. His hematemesis is most likely related to his acute ingestion. And finally, he has an anion gap metabolic acidosis, as evidenced by his low pH and low HCO3. All of these salient factors bring up the concern for acute iron ingestion! In today's episode, we will not only go through acute management pearls for iron poisoning, but also go back to the fundamentals, and cover ACID BASE disorders. We will break this episode down into giving a broad overview of acid base, build a stepwise approach, and apply our knowledge with integrated cases. We will use a physiologic approach to cover this topic! Pradip, can you give us a quick overview of some general principles when it comes to tackling this high-yield critical care topic? Absolutely, internal acid base homeostasis is paramount for maintaining life. Moreover, we know that accurate and timely interpretation of an acid–base disorder can be lifesaving. When we conceptualize acid base today, we will focus on pH, HCO3, and CO2. As we go into each disorder keep in mind to always correlate your interpretation of blood gasses to the clinical status of the patient. Going back to basic chemistry, can you comment on the relationship between CO2 and HCO3? Yes, now this is a throwback. However, we have to review the Henderson–Hasselbalch equation. The equation has constants & logs involved, however in general this equation shows that the pH is determined by the ratio of the serum bicarbonate (HCO3) concentration and the PCO2, not by the value of either one alone. In general, an acid–base disorder is called “respiratory” when it is caused by a primary abnormality in respiratory function (i.e., a change in the PaCO2) and “metabolic” when the primary change is attributed to a variation in the bicarbonate concentration. Now that we have some fundamentals down, let's move into definitions. Can you define acidemia and alkalemia and comment on how...

Welcome to PICU Doc On Call, a podcast dedicated to current and aspiring intensivists. My name is Pradip Kamat My name is Rahul Damania, a current 3rd-year pediatric critical care fellow and we are coming to you from Children's Healthcare of Atlanta Emory University School of Medicine Today's episode is dedicated to the transition between NICU & PICU. We will focus on the ventilation of the ex-premature infant who graduated from NICU care and transitioned to the PICU. I will turn it over to Rahul to start with our patient case. Case: A 4-month-old ex-27 week baby boy is transferred to our PICU after an echo at an outside hospital showed elevated pulmonary pressures. The infant was born via a stat C-section due to maternal complications during pregnancy. His birth weight was 560 g. The patient was intubated shortly after delivery and had a protracted course in the NICU which included a sepsis rule out, increased ventilator settings, and a few weeks on inhaled nitric oxide (iNO). The intubation course was complicated pulmonary hemorrhage on day 1 after intubation. After such an extensive NICU course, thankfully, the infant survived & was sent home on 1/2 LPM NC, diuretics, albuterol, inhaled corticosteroids, Synthroid, multivitamin with iron as well as Vitamin D. The patient was able to tolerate breast milk via NG tube and had a home apnea monitor with pulse oximetry. After about a week's stay at home, the mother noted that the patient's SPO2 was in the low 80s. The mother took the patient to the local hospital, where the patient was started on HFNC which improved his saturations. An echo done at the OSH showed elevated RV pressures (higher than the prior echo). The patient was subsequently transferred to our hospital for further management. At our hospital, the patient presented hypoxemic, tachycardic, and tachypneic. On physical exam: Baby appeared well developed, had a systolic murmur heard throughout the precordium, and there was increased WOB with significant intercostal retraction. There was no hepatosplenomegaly. Due to worsening respiratory distress, and increasing FIO2 requirement despite maximum RAM cannula, the patient was intubated and placed on conventional MV. A blood gas prior to intubation revealed a pH of 7.1/PCO2 of 100. An arterial line and a central venous line were also placed for better access and monitoring. Initial vent settings post intubation PRVC ventilation: TV 32cc, (25/10), 0.7 time, rate 0 (patient sedated/paralyzed). To summarize, What are some of the features in H&P that are concerning for you in this case: Ex-27 week prematurity with a birth weight of 560 gms Prolonged MV in the NICU Home O2 requirement Abnormal echo showing high pulmonary pressures hypercarbia despite the use of RAM cannula As mentioned, our patient was intubated, can you tell us pertinent diagnostics which were obtained? CXR revealed: Hazy airspace opacification in the right upper lung concerning developing pneumonia. Streaky airspace opacity in the left lung base medially may represent atelectasis. I do want to highlight that the intubation of an ex-premie especially with elevated RV pressures is a high-risk scenario, it is best managed by a provider with experience, in a very controlled setting with optimal team dynamics. Adequate preparation to optimize the patient prior to the intubation as well as the knowledge to manage the post intubation cardiopulmonary interactions are essential. I would highly advise you to re-visit our previous podcast on intubation of the high-risk PICU patient by Dr. Heather Viamonte. Like many Peds ICU conditions, the management of the EX-NICU graduate in the PICU is a multidisciplinary team sport. Our patient likely has the diagnosis of Bronchopulmonary Dysplasia or BPD, Pradip, can you comment on the evolving definition of this diagnosis? Let me first define BPD — Clinically, BPD is defined by a requirement of oxygen supplementation either at...

Welcome to PICU Doc On Call, a podcast dedicated to current and aspiring intensivists. I am Pradip Kamat. I am Rahul Damania, a current 3rd year pediatric critical care fellow. I am Kate Phelps- a second year pediatric critical care medicine. We come to you from Children's Healthcare of Atlanta Emory University School of Medicine. We are delighted to be joined by guest expert Dr Stephanie Jernigan Assistant Professor of Pediatric-Pediatric nephrology, Medical Director of the Pediatric Dialysis Program at Children's Healthcare of Atlanta. She is the Chief of Medicine and Campus Medical Director at Children's Healthcare of Atlanta, Egleston Campus. Her research interests include chronic kidney disease, and dialysis. She is on twitter @stephaniejern13 I will turn it over to Rahul to start with our patient case... A 3 year old previously healthy male presents with periorbital edema. Patient was initially seen by a pediatrician who prescribed anti-histamines for allergy. After no improvement in the eye swelling after a two week anti-histamine course, the patient was given a short course of steroids, which also did not improve his periorbital edema. The patient progressed to having abdominal distention and was prescribed miralax for constipation. Grandparents subsequently noticed worsening edema in his face, eyes, and feet. The patient subsequently had low urine output, low appetite and lack of energy patient was subsequently brought to an ED and labs were obtained. Grandparents denied any illness prior to presentation, fever, congestion, sore throat, cough, nausea, vomiting, gross hematuria, or diarrhea. In ED patient was noted to be hypertensive (Average systolic 135-highest 159mm HG), tachycardic (HR 130s-140s), breathing ~20-30 times per minute on RA with SpO2 92%. Admission weight was recorded at 16.5Kg. Physical exam showed periorbital edema, edema of ankles, there was mild abdominal distention (no tenderness and no hepatosplenomegaly), heart and lung exams were normal. There were no rashes on extremities. Labs at the time of transfer to the PICU: WBC 10 (62% neutrophils, 26% lymphocytes) Hgb 7.2, Hct 21, Platelets 276. BMP: Na 142/K 8.4/Cl 102/HCO3 19/BUN 173/creatinine 5.8. Serum phosphorus was 10.5, Total Ca 6.4 (ionized Ca= 3.4), Mag 2.0, albumin 2.6, AST/ALT were normal. An urine analysis showed: 1015, ph 7.5, urine protein 300 and rest negative. Chest radiograph revealed small bilateral pleural effusions. After initial stabilization of his hyperkalemia-patient was admitted to the PICU. PTH intact 295 (range 8.5-22pg/mL). Respiratory viral panel including for SARS-COV-2 was negative. C3 and C4 were normal. A nephrotic syndrome/FSGS genetic panel was sent. A renal US showed: bilateral echogenic kidneys and ascites (small volume). Pradip: Dr Phelps what are the salient features of the above case presented? Kate Phelps: This patient has a subacute illness characterized by edema, anemia, and proteinuria. His labs show that he has severe acute kidney injury with significantly elevated BUN and Creatinine, hyperkalemia, hyperphosphatemia, and hypocalemia. Rahul: Dr Jernigan welcome to PICU Doc on Call Podcast. Thanks Kate, Rahul and Pradip for inviting me to your podcast. This is a such a great way to provide education and it is my pleasure to come today to speak about one of my favorite topics, pediatric dialysis. I have no financial disclosures or conflicts of interest and am ready to get started. Rahul: Dr Jernigan as you get that call from the ED and then subsequently from the PCCM docs, as a nephrologists whats going on in your mind ? When I get the call from the outside hospital my first job is to make sure the patient is safe and stable for transfer to a tertiary care center. This includes concern about airway, breathing and level of alertness. From a renal standpoint, I am worried about elevated blood pressure, electrolyte abnormalities, in this case primarily the hyperkalemia, and fluid...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kamat I'm Rahul Damania, a third-year PICU fellow. I'm Kate Phelps, a second-year PICU fellow and we are all coming to you from Children's Healthcare of Atlanta - Emory University School of Medicine, joining Pradip and Rahul today. Welcome to our episode, where will be discussing gastrointestinal bleeding. Kate: Let's start with a case: A 4-year-old, previously healthy male presents to the emergency room after a large, bloody stool at home. He notably had an episode of dark emesis and an episode of blood-tinged emesis on the day prior. In triage, he is altered and unable to answer questions coherently. Initial vital signs are temperature 36.1 C, RR 24, HR 146, BP 110/54. Point-of-care labs show hemoglobin to be 5.1 with hematocrit 15. His venous blood gas is reassuring against respiratory disease, and he is in no respiratory distress. Further labs are sent and a massive transfusion protocol is initiated before transfer to the PICU. Before arrival in the PICU, he receives two aliquots of RBCs, 1 aliquot of FFP, and 1 aliquot of platelets. Additional labs are sent from the PICU, post-transfusion. His post-transfusion hemoglobin is 8.8. Other labs are notable for normal MCV, elevated total bilirubin to 4.1 (with direct component 3.4), and elevated AST and ALT to 309 and 495 respectively. Rahul: To summarize key elements from this case, this patient has: An undifferentiated gastrointestinal bleed with both hematemesis and hematochezia. He has symptomatic anemia, as evidenced by tachycardia Altered mental status. He is initially stabilized via transfusion of several blood products and liver function labs are shown to be very abnormal — which we will get more into later! PK: Let's get into important parts of the history and physical. Kate, can you tell me what some key history items in this patient are — and what are some areas to make sure to touch on when a patient has a GI bleed? Kate: Yeah! I'd love to. First - in our patient, some important elements are his rather acute onset. His parents mention he has had one day of bleeding symptoms - first with emesis yesterday, with components of old, partially digested blood, as well as some fresh blood. Second, he has a frankly bloody stool at home. Given his clinical instability, history taking was probably limited at first, so it's important to ask follow-up questions and really dig into the case after stabilization! I like to put my questions about gastrointestinal bleeding into buckets based on the questions I need to answer. I need to answer: is this active bleeding or old blood? Is this slow, insidious bleeding or fast, life-threatening bleeding? Is this an upper GI bleed or a lower GI bleed? Bright red blood in emesis tells us that bleeding is active, whereas coffee-ground or dark emesis tells us that, while recent, the blood has been partially digested in the stomach and may not be ongoing. Similarly, melena (dark, tarry stool), tells us blood has come through the colon. While coffee-ground emesis and melena don't rule out an active bleed, they do tell us the bleeding may be slower, as large volume, active bleedy is irritating to the stomach and gastrointestinal tracks and moves through the system quickly. The next question I want to answer is: what is the cause of this bleed? Easy bruising, petechiae and mucosal bleeding may point to a coagulation disorder. Abdominal cramping, frequent stooling, and weight loss may point to inflammatory bowel disease. Past medical history, family history, and a thorough review of systems are key here. Rahul: Yeah, that's great! Let's talk about your question of upper GI vs lower GI bleed. First, a definition: an upper GI bleed is bleeding that occurs above the ligament of Treitz — which is ligamentous tissue that supports the end of the duodenum and beginning of the jejunum at their junction. While not 100% specific, some...

Welcome to PICU Doc On Call, A Podcast Dedicated to Current and Aspiring Intensivists. I'm Pradip Kama and I'm Rahul Damania, a third-year PICU fellow. I'm Kate Phelps, a second-year PICU fellow and we are all coming to you from Children's Healthcare of Atlanta, Emory University School of Medicine, joining Pradip and Rahul today. Welcome to our episode, where will be discussing rhabdomyolysis and associated acute kidney injury in the ICU. Rahul: Here's the case, a 7-year-old female presents to the ED with three days of fever, poor PO, and diffuse myalgia. In the ED, her vital signs are T 39.1C, HR 139, BP 82/44, RR 32. She is pale and diaphoretic, complaining weakly about how much her legs hurt. Her parents note that she has not been peeing very well since yesterday, and when she does pee it is “very concentrated, almost brown.” She's also been spending all her time on the couch and has asked to be carried to the bathroom when she does need to go. An IV is placed by the emergency room team, and she is given a fluid bolus, acetaminophen, and initial labs are drawn (CMP, CBC, RSV/Flu swab) before she is admitted to the PICU. In the PICU, her fever is better and her vitals have improved to T 37.7, HR 119, BP 115/70, and RR 25. Her respiratory swab has just resulted positive for Influenza A. Further labs are sent, including creatine kinase (CK), coagulation studies, and a urinalysis. Labs are notable for K 3.9, Bicarb 22, BUN 15, Cr 0.8, and CK 5768 IU/L. Her urinalysis is notable for 1 WBC, 2 RBC, +3 blood, negative nitrites, and leukocyte esterase. Kate: To summarize key elements from this case, this patient has: Influenza A, as evidenced by her respiratory swab, as well as her clinical prodrome. She has diffuse myalgias, as well as fevers, diaphoresis, and hypotension. Labs are most notable for elevated creatinine and elevated creatine kinase, as well as an abnormal urinalysis. All of which brings up a concern for rhabdomyolysis and myoglobin-induced acute kidney injury. Before we get into this episode — let's create a mental framework for this episode — we will dissect our case by highlighting key H&P components, visit a differential diagnosis, pivot to speaking about pathophysiology, and finally, speak about management! Rahul: Let's transition into some history and physical exam components of this case. The classic presentation of rhabdomyolysis is myalgias, muscle weakness, and tea-colored urine, all of which our patient has. Decreased urinary output can also accompany, a variety of reasons, but most notably if the patient has myoglobin-induced acute kidney injury. In our patient, poor PO is also probably contributing to her decrease in urine output. Red flag signs or symptoms will include anuria, hypotension, and altered mental status (which is rare but may indicate severe acidemia and deterioration) Pradip: As we think about our case, what other disease processes might be in our differential? As we dive in a bit more, we'll come up with ways to distinguish between rhabdo and other things! Viral myositis - inflammation in the muscles in the setting of a viral illness, which can definitely happen with influenza and other common viruses Some other things which may cause reddish-brown urine, including hematuria, hemoglobinuria, porphyria, some specific foods or drugs (like rifampin, beets, food coloring — even ibuprofen) We also have to investigate a bit more to convince ourselves that our patient's AKI is due to rhabdomyolysis, as it could be from dehydration, sepsis, NSAIDS, etc. Kate: Let's dive further into rhabdomyolysis! Rhabdomyolysis affects over 25,000 adults and children every year. While toxins (including prescription drugs, alcohol, and illicit drugs) and trauma are two common causes of rhabdo in adults (and teens), infections, especially viruses, are the most common cause in young children. Influenza, EBV, and CMV are three most commonly reported. What's the pathophysiology of...
