Trauma Resuscitation and the Covid-19 Pandemic in South Africa In this podcast, Roger Harris interviews Victoria Stephen about her experience as an emergency physician in a regional South African hospital. Sadly, trauma resuscitation is a big part of working in Emergency Medicine in South Africa. Ā Blunt force assaults and stab wounds are regular presentations. However, July 2021 was unlike anything Doctor Victoria Stephen had ever experienced. In July, South Africa was deep intoĀ its' third wave of Covid-19 infections. Vaccination rates were low and there was a huge burden of Covid patients in the Emergency Department. The ICU was completely overwhelmed, making this by far the worst of the pandemic that they had seen to date. To compound this, piped oxygen levels were running desperately low. The hospital relied on daily oxygen deliveries to keep Covid patients alive. Moreover, to add to the challenge, political unrest broke out and quickly escalated to riots with extreme violence across South Africa. At the time the violence erupted, Tori had over 120 Covid patients in the hospital.Ā Added to this the Trauma resuscitation was managing approximatelyĀ 34 patients with gunshot woundsĀ per day. With just four doctors working at night and six doctors working during the day, Tori's team scrambled to manage an overwhelming number ofĀ high acuityĀ patients. For the first time in her career, Tori found herself frightened for her safety. Having grown up in South Africa, Tori was no stranger to avoiding danger but this felt very out of control. The thought of managingĀ a busy emergency department inundated with trauma patients in the middle of the covid pandemic is frightening enough for most of us, but to do so in such a resource-limited environment with so few nurses and doctors is truly incredible. Tori believes Emergency Medicine training in South Africa prepares the team to function under such pressure. She believes that the team knows that the lack of resources means they must all pull together. Their training is diverse enough that they have the mental and clinicalĀ skills to step up and of course as an ultrasound geek Tori adds that EFAST scanning has a big role to play. Tori isĀ a humble but inspirational clinician onĀ the frontline of providing care in aĀ volatileĀ environment and she believes we can all learn something from her experience. Tune in to a compellingĀ conversation with one of our favourites. Trauma Resuscitation and the Covid-19 Pandemic in South Africa Finally, for more like this head to our podcast page #CodaPodcast
In this session, we interview Gaynor Prince. Gaynor is an emergency physician based in New Zealand and has developed a subspecialty interest in ultrasound in ED. We take a look at point of care ultrasound, its utility and its limitations. We will be especially focussing on the EFAST and how it has been adaptive and progressive in point of care treatment in the past 5 years. We also take a look at ultrasound probes and the positive and negative interaction with tissue. Gaynor unpacks some of the fundamental advantages and disadvantages of POCUS and how it has been adapted, been made portable and democratised amongst clinicians in recent years. We unpack the principles of EFAST, what we are looking for, when to look and where. We examine the difference image representations of fluid, blood, ascites, urine, intestinal contents, lungs, air. Gaynor them looks at the anatomical variations and how to optimise the view, interplay with clinical questioning, repetition of scans and preferential windows to see the anatomy. We go sequentially through the EFAST and look at tips and tricks from Gaynor's practice and how these can be related to everyone's ultrasound practice and decision making. We finally look at a prime example of when USS has been really useful to Gaynor's practice in one of the remotest and most extreme environments - Antarctica. She recalls a story of when ultrasound greatly assisted her decision making, illustrating some of the unique examples of this modality in remote and austere locations.

Contributor: Aaron Lessen, MD Educational Pearls:.Ā Ā Focused assessment with Sonography for Trauma (FAST) exam and the extended-FAST (eFAST) are essential components of current trauma care and evaluation There has been an accumulation of research to provide an estimate of effectiveness of identifying certain injuries with ultrasound: For identifying a pneumothorax, the sensitivity ~70% and specificity ~99%. For pericardial effusions, sensitivity 90% and specificity ~ 94%. For hemoperitoneum, sensitivity ~74% and the specificity ~98%. While ultrasound is excellent for identifying many injuries, it may not be adequate alone to rule out serious injuries if the clinical suspicion is high based on these pooled studies References Netherton S, Milenkovic V, Taylor M, Davis PJ.

Show Notes Jeff: Welcome back toĀ EMplify, the podcast corollary to EB Medicineās Emergency Medicine Practice. Iām Jeff Nusbaum, and Iām back with my co-host, Nachi Gupta. This month, after a few months of primarily medical topics, weāre talking trauma, specificallyĀ Blunt Cardiac Injury: Emergency Department Diagnosis and Management. Nachi: With no gold standard diagnostic test and with complications ranging from simple ectopic beats to fulminant cardiac failure and death, this isnāt an episode youāll want to miss. Jeff: Before we begin, let me give a quick shout out to our incredible group of authors from New York -- Dr. Eric Morley, Dr. Bryan English, and Dr. David Cohen of Stony Brook Medicine and Dr. William Paolo, residency program director at SUNY Upstate. I should also mention their peer reviewers Drs. Jennifer Maccagnano and Ashley Norse of the NY institute of technology college of osteopathic medicine and UF Health Jacksonville, respectively. Nachi: This monthās team parsed through roughly 1200 articles as well as guidelines from the eastern association for surgery in trauma also known as EAST. Jeff: Clearly a large undertaking for a difficult topic to come up with solid evidence based recommendations. Nachi: For sure. Letās begin with some epidemiology, which is admittedly quite difficult without universally accepted diagnostic criteria. Jeff: As you likely know, despite advances in motor vehicle safety, trauma remains a leading cause of death for young adults. In the US alone, each year, there are about 900,000 cases of cardiac injury secondary to trauma. Most of these occur in the setting of vehicular trauma. Nachi: And keep in mind, that those injuries donāt occur in isolation as 70-80% of patients with blunt cardiac injury sustain other injuries. This idea of concomitant trauma will be a major theme in todayās episode. Jeff: It certainly will. But before we get there, we have some more definitions to review - cardiac concussion and contusion, both of which were defined in a 1989 study. In this study, cardiac concussion was defined as an elevated CKMB with a normal echo, while a cardiac contusion was defined as an elevated CKMB and abnormal echo. Nachi: Much to my surprise, though, abnormal echo and elevated ck-mb have not been shown to be predictive of adverse outcomes, but conduction abnormalities on ekgs have been predictive of development of serious dysrhythmia Jeff: More on complications in a bit, but first, returning to the idea of concomitant injuries, in one autopsy study of nearly 1600 patients with blunt trauma - cardiac injuries were reported in 11.9% of cases and contributed to the death of 45.2% of those patients. Nachi: Looking more broadly at the data, according to one retrospective review, blunt cardiac injury may carry a mortality of up to 44%. Jeff: Thatās scary high, though I guess not terribly surprising, given that we are discussing heart injuries due to major trauma... Nachi: The force may be direct or indirect, involve rapid deceleration, be bidirectional, compressive, concussive, or even involve a combination of these. In general, the right ventricle is the most frequently injured area due to the proximity to the chest wall. Jeff: Perfect, so that's enough background, letās talk differential. As you likely expected, the differential is broad and includes cardiovascular injuries, pulmonary injuries, and other mediastinal injuries like pneumomediastinum and esophageal injuries. Nachi: Among the most devastating injuries on the differential is cardiac wall rupture, which not surprisingly has an extremely high mortality rate. In terms of location of rupture, both ventricles are far more likely to rupture than the atria with the right atria being more likely to rupture than the left atria. Atrial ruptures are more survivable, whereas complete free wall rupture is nearly universally fatal. Jeff: Septal injuries are also on the ddx. Septal injuries occur immediately, either from direct impact or when the heart becomes compressed between the sternum and the spine. Delayed rupture can occur secondary to an inflammatory reaction. This is more likely in patients with a prior healed or repaired septal defects. Nachi: Valvular injuries, like septal injuries, are rare. Left sided valvular damage is more common and carries a higher mortality risk. In order, the aortic valve is more commonly injured followed by the mitral valve then tricuspid valve, and finally the pulmonic valve. Remember that valvular damage can be due to papillary muscle rupture or damage to the chordae tendineae. Consider valvular injury in any patient who appears to be in cardiogenic shock, has hypotension without obvious hemorrhage, or has pulmonary edema. Jeff: Next on the ddx are coronary artery injuries, which include lacerations, dissections, aneurysms, thrombosis, and even MI secondary to increased sympathetic activity and platelet activity after trauma. In one review, dissection was the most commonly uncovered pathology, occurring 71% of the time, followed by thrombosis, which occured only 7% of the time. The LAD is the most commonly injured artery followed by the RCA. Nachi: Pericardial injury, including pericarditis, effusion, tamponade, and rarely rupture, is also certainly on the differential. Jeff: In terms of dysrhythmias, sinus tachycardia is the most common dysrhythmia, with other rhythms, including PVC / PAC / and afib being found only 1-6% of the time. Nachi: And while conduction blocks are rare, a RBBB is the most commonly noted, followed by a 1st degree AVB. Jeff: Though also rare, commotio cordis deserves itās own section as its the second most common cause of death in athletes < 18 who are victims of blunt trauma. Though only studied in swine models, itās hypothesized that the impact to the chest wall during T-wave upstroke can precipitate v-fib. Nachi: Aortic root injuries usually occur at the insertion of the ligamentum arteriosum and isthmus. Such injuries typically result in aortic insufficiency. Jeff: And the last pathology on the differential requiring special attention is a myocardial contusion. Again, no standard definition exists, with some diagnostic criteria including simply chest pain and increasing cardiac enzymes, and others including cardiac dysfunction, ecg abnormalities, wall motion abnormalities, and an elevation of cardiac enzymes. Nachi: Certainly a pretty broad differential⦠before moving on to the work up, Jeff why donāt you get us started with prehospital care? Jeff: Prehospital management should focus on rapid identification and stabilization of life threatening injuries with expeditious transport as longer prehospital times have been associated with increased mortality in trauma. Immediate transport to a Level I trauma center should be the highest priority for those with suspected blunt cardiac injury. Nachi: In terms of who specifically should be transporting the patient, a Cochrane review evaluated the utility of ALS vs BLS transport in trauma. There is reasonably good data to support BLS over ALS, even when controlling for trauma severity. Moreover, when airway management is needed, advanced airway techniques by ALS crews were associated with decreased odds of survival. Regardless of who is there, the message is the same: focus not on interventions, but instead on rapid transport. Jeff: And if it does happen to be an ALS transport crew, without delaying transport, pain management with fentanyl is both safe and reasonable and preferred over morphine. Post opiate hypotension in prehospital trauma patients is a rare but documented complication. Nachi: And if the prehospital team is lucky enough, or maybe unlucky enough, i donāt know, to have a credentialed provider who can perform ultrasound for those suspected of having a blunt cardiac injury, the general prehospital data on ultrasound is sparse. As of now, itās difficult to conclude if prehospital US improves care for trauma patients. Jeff: Interestingly, the system I work in has prehospital physicians, who do carry US, but I canāt think of a major trauma where ultrasound changed any of the decisions we made. Nachi: Right, and I think that just reinforces the main point here: there may be a role, we just donāt have the data to support it at this time. Jeff: Great, letās move onto ED care, beginning with the H&P. Nachi: On history, make sure to elucidate if there is any chest pain, and if itās onset was before or after the traumatic event. In addition, make sure to ask about dyspnea, fatigue, palpitations, and lightheadedness. Jeff: And donāt forget to get the crash details from the EMS crew before they depart! As a side note, for anyone taking oral boards in a few months, donāt forget to ask the EMS crew for the details!!! Nachi: A definite must for oral boards and for your clinical practice. Jeff: In terms of the physical, tachycardia is the most common abnormality in blunt cardiac injury. In those with severe injury, you may note refractory hypotension secondary to cardiogenic shock. But donāt be reassured by normal vitals, especially in the young, who may be compensating well despite being quite ill. Nachi: Fully undress the patient to appropriately inspect and percuss the chest wall - looking for signs of previous cardiac surgeries or pacemaker placement, as well as to auscultate for new murmurs which may be a sign of valvular injury. Jeff: Similarly, as concomitant injuries are common, inspect the abdomen, looking for ecchymosis patterns, which often accompany blunt cardiac injury. Nachi: Pretty standard stuff. Letās move on to diagnostic testing. Jeff: Lab testing should include a CBC, BMP, coags, troponin, lactate, and T&S. In one retrospective analysis, an elevated troponin and a lactate over 2.5 were predictors of mortality. Nachi: Additionally, in patients with chest trauma, a troponin > 1.05 was associated with a greater risk for dysrhythmias and LV dysfunction. Jeff: And it likely goes without saying, but an EKG is a must on all trauma patients with suspicion for blunt cardiac injury in accordance with the EAST guidelines. New EKG findings requires admission for monitoring. Unfortunately, on the flip side, an ECG cannot be used to rule out blunt cardiac injury. Nachi: Diving a bit deeper into the data, in a prospective study of 333 patients with blunt thoracic trauma, serial EKG and troponins at 0, 4, and 8 hours post injury had a sensitivity and specificity of 100% and 71%, respectively. However, of those with abnormal findings, all but one had them on initial testing, leading to a negative predictive value of 98%. Jeff: Well thatās an impressive NPV and has huge implications, especially in the era of heavily monitored lengths of stay... Nachi: Definitely. In terms of radiography, a chest x-ray should be obtained as rib fractures, hemopneumothorax, and mediastinal free air are all things you wouldn't want to miss and are also associated with blunt cardiac injury. Jeff: Keep in mind, however, that the chest x-ray should not be seen as a test for pericardial fluid as up to 200 mL of fluid can be contained in the pericardial space and remain undetectable by chest radiograph. Nachi: Which is why youāll have to turn to our good friend the ultrasound, for more useful data. The data is strong that in the hands of trained Emergency Clinicians, when parasternal, apical, and subcostal views are obtained, US has an accuracy of 97.5% for pericardial effusion. Jeff: Not only is US accurate, itās also quick. In one RCT, the FAST exam reduced the time from arrival in the ED to operative care by 64% in the setting of trauma. Nachi: Thatās impressive -- for expediting patient care and for managing ED flow. Jeff: Exactly. The authors do note however that hemopericardium is a rare finding, so, while not the focus of this article, the real utility of the FAST exam may be in its expanded form, the eFAST, in which a rapid bedside ultrasonographic lung exam for pneumothorax is included, as this can lead to immediate changes in management. Nachi: And assuming you do your FAST or eFAST and have no management changing findings, CT will often be your next test. Jeff: Yeah, EKG-gated multidetector CT can easily diagnose myocardial rupture, pneumopericardium, pericardial rupture, hemopericardium, coronary artery insult, ventricular septal defects and even valvular dysfunction. Unfortunately, CT does not perform well for the evaluation of myocardial contusions. Nachi: This is all well and good, and certainly accurate, but letās not forget that hemodynamicallyĀ unstable trauma patients, like those with myocardial rupture, need to be in the operating room, not the CT scanner. Jeff: An important point that should not be understated. Nachi: And the last major testing modality to discuss is the echocardiogram. Jeff: The echo is a fantastic test for detecting focal cardiac dysfunction often see with cardiac contusions, hemopericardium, and valve disruption. Nachi: And itās worth noting that transthoracic is enough, as transesophageal, despite the better images, hasnāt been shown to change management. TEE should be saved for those in whom a optimal TTE study isnāt feasible. Jeff: Great point. And one last quick note on echo: in terms of guidelines, the EAST guidelines from 2012 specifically recommend an echo in hemodynamically unstable patients or those with a persistent new dysrhythmia without other sources of ongoing hemorrhage or neurologic etiology of instability. Nachi: Perfect, so that wraps up testing and imaging for our blunt cardiac injury patient. Letās move on to treatment. Jeff: In terms of initial resuscitation, there is an ever increasing body of literature to support blood transfusion over crystalloid in patients requiring volume expansion in trauma. There are no specific guidelines for transfusion in the setting of blunt cardiac injury, so stick to your standard trauma protocols. Nachi: It is worth noting, though, that there is literature outside of trauma for those with pericardial effusions, suggesting that those with a SBP < 100 have substantial benefit from volume expansion. So keep this in mind if your clinical suspicion is high and your trauma patient has a soft but not truly shocky blood pressure. Jeff: Operative management, specifically ED thoracotomy is a heavily debated topic, and itās next on our list to discuss. Nachi: The 2015 EAST guidelines conditionally recommend ED thoracotomy for moribund patients with signs of life. The Western Trauma Association broadens the ED thoracotomy window a bit to include anyone with no signs of life but less than 10 minutes of CPR. The latter also recommend ED thoracotomy in those with refractory shock. Jeff: Though few studies exist on the topic, in one study of 187 patients, cardiac motion on US was 100% sensitive for predicting survivors. Nachi: Not great data, but it does support one's decision to stop any further work up should there be no cardiac activity, which is important, because the decision to pursue an ED thoracotomy is not an easy one. Jeff: And lastly, emergent pericardiocentesis may be another option in an unstable patient when definitive operative management is not possible. But do note that pericardiocentesis is only a temporizing measure, and not definitive for cardiac tamponade. Nachi: Treatment for dysrhythmias is standard, treat in accordance with standard ACLS protocols, as formal randomized trials on prophylaxis and treatment in the setting of blunt cardiac injury do not exist. Jeff: Seems reasonable enough. And in the very rare setting of an MI after blunt cardiac injury, you should involve cardiology, cardiothoracic surgery, and trauma to help make important management decisions. Data is, again, lacking, but the patient likely needs percutaneous angiography for appropriate diagnosis and potentially further intervention. Definitely hold off on ASA and likely nitroglycerin, at least until significant bleeding has been ruled out. Nachi: Yup, no style points for giving aspirin to a bleeding trauma patient. Speaking of medications, the last treatment modality to discuss here is pain control. Pain management is essential with chest injuries, as appropriate pain management has been shown to reduce mortality in pulmonary related complications. Jeff: And in line with every acute pain consult note Iāve ever come across, a multimodal approach utilizing opioids and nonopioids is recommended. Nachi: Perfect, so that sums up treatment, next we have one special circumstance to discuss: sternal fractures. Cardiac contusions are found in 1.8-2.4% of patients with sternal fractures, almost all of which were seen on CT and not XR according to the NEXUS chest CT study. Of these patients, only 2 deaths occured, both due to cardiac causes.Ā Thus, in patients with isolated sternal fractures, negative trops, ekg, and negative cxr - the patient can likely be discharged from the ED, as long as their pain is well-controlled. Jeff: And letās talk controversies for this issue. We only have one to discuss: MRI. Nachi: The fact that MRI produces awesome images is not controversial, see figure 3. Itās role, however, is. In accordance with EAST guidelines, MRI may be most useful in differentiating acute ischemia from blunt cardiac injury in those with abnormal ECGs, elevated enzymes, or abnormal echos. Itās use in the hyperacute evaluation, however, is limited, in large part owing to the length of time required to complete an MRI Jeff: What a time to be alive that we even have to say that MRIs may not have a hyperacute role in trauma - absolutely crazy... Nachi: Moving on to disposition: any patient with aortic, pericardial, or myocardial injury and hemodynamic instability needs operative evaluation and likely intervention, so do not hesitate to get the consults coming or the helicopter in the air should such a patient arrive at your non-trauma center. Jeff: And in those that are hemodynamically stable, with either a positive ECG or a positive trop, they should be monitored on telemetry. There is no clear answer as to how long, but numerous studies suggest a 24 hour period of observation is sufficient. For those with persistent ekg abnormalities or rising trops - this is precisely when you will want to pursue echocardiography. Nachi: And if there are positive EKG findings AND a rising trop, they should be admitted to a step down unit or ICU as well -- as ā of them will develop myocardial dysfunction. Similarly, those with hemodynamic instability but no active traumatic bleeding source - they too should be admitted to the ICU for a STAT echo and serial enzymes. Jeff: But in the vast majority of patients, those that are hemodynamically stable with negative serial EKGs and serial tropinins, they can effectively be ruled out for significant BCI after an 8 hour ED observation period, as we mentioned earlier with a sensitivity approaching 100%! Nachi: Though there are, of course, exceptions to this rule, like those with low physiologic reserve, mobility or functional issues, or complex social situations, which may need to be assessed on a more case-by-case basis. Jeff: Letās wrap up this episode with some key points and clinical pearls. Cardiac wall rupture is the most devastating form of Blunt Cardiac Injury. The sealing of a ruptured wall may lead to a pseudoaneurysm and delayed tamponade. Trauma to the coronary arteries may lead to a myocardial infarction. The left anterior descending artery is most commonly affected. The most common arrhythmia associated with blunt cardiac injury is sinus tachycardia. RBBB is the most commonly associated conduction block. Commotio cordis is the second most common cause of death in athletes under the age of 18. Early defibrillation is linked to better outcomes. Antiplatelet agents like aspirin should be avoided in blunt cardiac injury until significant hemorrhage has been ruled out. An EKG should be obtained in all patients with suspected blunt cardiac injury. However, an EKG alone does not rule out blunt cardiac injury. Serial EKG and serial troponin testing at hours 0, 4, and 8 have a sensitivity approaching 100% for blunt cardiac injury. An elevated lactate level or troponin is associated with increased mortality in blunt cardiac injury. Perform a FAST exam to assess for pericardial effusions. FAST exams are associated with a significant reduction in transfer time to an operating room. Obtain a chest X-ray in all patients in whom you have concern for blunt cardiac injury. Note that the pericardium is poorly compliant and pericardial fluid might not be detected on chest X-ray. Transesophageal echocardiogram should be considered when an optimal transthoracic study cannot be achieved. CT is used routinely in evaluating blunt chest trauma but know that it does not evaluate cardiac contusions well. In acute evaluation, MRI is generally a less useful imaging modality given the long imaging time. There is evidence to suggest that a patient with an isolated sternal fracture and negative biomarkers and negative EKG findings can be safely discharged from the ED if pain is well-controlled. Trauma to the aorta, pericardium, or myocardium is associated with severe hemodynamic instability. These patients need surgical evaluation emergently. Hemodynamically stable patients with a positive troponin test or with new EKG abnormalities should be observed for cardiac monitoring. Nachi: So that wraps up Episode 26 onĀ Blunt Cardiac Injury!

Most of us working any length of time in emergency medicine are either familiar with or perform the (extended) Focused Assessment of Sonography in Trauma (eFAST).Ā Some keep with the original FAST exam which does not include the lungs, and we will talk more about why you want to include the lungs in a separate podcast.Ā However, after having just returned from 2018 AASPA ConferenceĀ where we taught participants about many clinically important exams, there were some details of the eFAST that simply could not be covered simply due to time.Ā This podcast is devoted to providing some quick tips to improve your exam no matter your practice level.

Asthma is a common disease and presents to acute healthcare services extremely frequently. The majority of presentations are mild exacerbations of a known diagnosis and are relatively simple to assess and treat, many being completely appropriate for out patient treatment. On the other hand around 200 deaths per year are attributable in the UK to asthma, and therefore in the relatively young group of patients there is a real potential for critical illness with catastrophic consequence if not treated effectively. The majority of these deaths occur prior to the patient making it to hospital making the prehospital phase extremely important and hugely stressful in these cases. It is also worth noting that of the deaths reported that many were associated with inadequate inhaled corticosteroids or steroid tablets and inadequate follow up, meaning that our encounter with these patients at all stages of their care even if not that severe at the point of assessment is a key opportunity to discuss and educate about treatment plans and reasons to return.

We're back with 3 superb topics this month! First off we have a look at the utility of ultrasound for the detection of pneumothoraces in the context of blunt trauma. Next weĀ look at the need to scanĀ facial bones when scanningĀ a patient's head following trauma. Last of all we look at a paper reviewing the association between the use of a bougie and the first pass success when performing ED RSI. Have a listen to the podcast and most importantly make sure you have a look at the references and critically appraise the papers yourself. We'd love to hear your thoughts and comments at the bottom of the page. Enjoy!

This is a deep dive into a recent lung US paper looking at the sensitivity of eFAST exam for pneumothorax in blunt trauma patients. The conclusion was a really low sensitivity... but as a skeptic and lung scan enthusiast, I have decided to explain how I think we should interpret this paper. Casey
This week we feature a short primer on penetrating chest trauma focusing on circulation first over airway and breathing. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Podcast_Episode_80_0_Final_Cut.m4a Download Leave a Comment Tags: ED Thoracotomy, EFAST, Resuscitative Thoracotomy, Trauma, Ultrasound Show Notes Take Home Points Don't rush to the airway. In most situations, you have some time so resuscitate before you intubate. Give blood products and get the BP up a bit to give yourself a little better physiologic situation in which to intubate. Start your massive transfusion immediately if the patient is shocked. There's always a delay in getting products but the earlier you start, the shorter the delay. Include US in your primary survey. Your E-FAST should start with the cardiac window, then go to the lungs and then, finally, the abdomen. This order focuses on finding pathology you can fix immediately. If the patient is shocked and peri-arrest or recently lost vitals, open the chest and look for a fixable injury. Start with opening the pericardium to relieve tamponade, identify and repair cardiac wounds and cross clamp the aorta. Read More Larry Mellick:

We are in the beautiful Las Vegas joined by EAST Traumacast covering the Trauma, Critical Care, Acute Care Surgery conference headed by Dr. Mattox who invited us to come down and talk to faculty, attendees, andĀ highlightĀ the day's events. On Day 2/3 we have two more great groupĀ discussions. Ā In the first discussion with leading surgeons Carlos Brown and Alison Wilson we discuss NSTIs and necrotizing pancreatitis and important tips and tricks for dealing with these often complicated scenarios. In the second group we have Richard Sidwell, Bellal Joseph, and return guest Martin Schreiber discussingĀ controversial trauma topics such as EFAST, TEG, and finally the future of stem cell use in trauma. Ā Day 3 tomorrow!! Ā Send your questions our way!
For the second part of trauma resuscitation, we'll discuss the various interventions that you may have to accomplish in the trauma bay. The first part is a continuation from the first episode and talks about the EFAST exam- a vital part of the secondary survey. The second part discusses the control of massive extremity hemorrhage and how to intervene on any airway, breathing, or circulation issue in the trauma bay.
