Steal can be caused by multiple factors—arterial occlusive disease proximal or distal to the AV anastomosis, high flow through the fistula at the expense of distal arterial perfusion, and failure of the distal arterial networks to adapt to this decreased blood flow.  Incidence and Risk Factors The frequency of steal syndrome is 1.6-9%1,2, depending on the vessels and conduit choice Steal syndrome is more common with brachial and axillary artery-based accesses and nonautogenous conduits. Other risk factors for steal syndrome are peripheral vascular disease, coronary artery disease, diabetes, advanced age, female sex, larger outflow conduit, multiple prior permanent access procedures, and prior episodes of steal.3,4  Long-standing insulin-dependent diabetes causes both medial calcinosis and peripheral neuropathy, which limits arteries' ability to vasodilate and adjust to decreased blood flow. Patient Presentation, Symptoms, Grading Steal syndrome is diagnosed clinically.  Symptoms after AVG creation occurs within the first few days, since flow in prosthetic grafts tend to reach a maximum value very early after creation. Native AVFs take time to mature and flow will slowly increase overtime, leading to more insidious onset of symptoms that can take months or years. The patient should have a unilateral complaint in the extremity with the AV access. Symptoms of steal syndrome, in order of increasing severity, include nail changes, occasional tingling, extremity coolness, numbness in fingertips and hands, muscle weakness, rest pain, sensory and motor deficits, fingertip ulcerations, and tissue loss.  There could be a weakened radial pulse or weak Doppler signal on the affected side, and these will become stronger after compression of the AV outflow. Symptoms are graded on a scale specified by Society of Vascular Surgery (SVS) reporting standards:5  Workup Duplex ultrasound can be used to analyze flow volumes. A high flow volume (in autogenous accesses greater than 800 mL/min, in nonautogenous accesses greater than 1200 mL/min) signifies an outflow issue. The vein or graft is acting as a pressure sink and stealing blood from the distal artery. A low flow volume signifies an inflow issue, meaning that there is a proximal arterial lesion preventing blood from reaching the distal artery. Upper extremity angiogram can identify proximal arterial lesions. Prevention Create the AV access as distal as possible, in order to preserve arterial inflow to the hand and reduce the anastomosis size and outflow diameter.  SVS guidelines recommend a 4-6mm arteriotomy diameter to balance the need for sufficient access flow with the risk of steal. If a graft is necessary, tapered prosthetic grafts are sometimes used in patients with steal risk factors, using the smaller end of the graft placed at the arterial anastomosis, although this has not yet been proven to reduce the incidence of steal.  Indications for Treatment Intervention is recommended in lifestyle-limiting cases of Grade II and all Grade III steal cases. If left untreated, the natural history of steal syndrome can result in chronic limb ischemia, causing gangrene with loss of digits or limbs. Treatment Options Conservative management relies on observation and monitoring, as mild cases of steal syndrome may resolve spontaneously. Inflow stenosis can be treated with endovascular intervention (angioplasty with or without stent) Ligation is the simplest surgical treatment, and it results in loss of the AV access. This is preferred in patients with repetitive failed salvage attempts, venous hypertension, and poor prognoses. Flow limiting procedures can address high volumes through the AV access. Banding can be performed with surgical cutdown and placement of polypropylene sutures or a Dacron patch around the vein or graft. The Minimally Invasive Limited Ligation Endoluminal-Assisted Revision (MILLER) technique employs a percutaneous endoluminal balloon inflated at the AVF to ensure consistency in diameter while banding Plication is when a side-biting running stitch is used to narrow lumen of the vein near the anastomosis. A downside of flow-limiting procedures is that it is often difficult to determine how much to narrow the AV access, as these procedures carry a risk of outflow thrombosis. There are also surgical treatments focused on reroute arterial inflow. The distal revascularization and interval ligation (DRIL) procedure involves creation of a new bypass connecting arterial segments proximal and distal to the AV anastomosis, with ligation of the native artery between the AV anastomosis and the distal anastomosis of the bypass. Reversed saphenous vein with a diameter greater than 3mm is the preferred conduit. Arm vein or prosthetic grafts can be used if needed, but prosthetic material carries higher risk of thrombosis. The new arterial bypass creates a low resistance pathway that increases flow to distal arterial beds, and interval arterial ligation eliminates retrograde flow through the distal artery.  The major risk of this procedure is bypass thrombosis, which results in loss of native arterial flow and hand ischemia. Other drawbacks of DRIL include procedural difficulty with smaller arterial anastomoses, sacrifice of saphenous or arm veins, and decreased fistula flow. Another possible revision surgery is revision using distal inflow (RUDI). This procedure involves ligation of the fistula at the anastomosis and use of a conduit to connect the outflow vein to a distal artery. The selected distal artery can be the proximal radial or ulnar artery, depending on the preoperative duplex. The more dominant vessel should be spared, allowing for distal arterial beds to have uninterrupted antegrade perfusion. The nondominant vessel is used as distal inflow for the AV access. RUDI increases access length and decreases access diameter, resulting in increased resistance and lower flow volume through the fistula. Unlike DRIL, RUDI preserves native arterial flow.  Thrombosis of the conduit would put the fistula at risk, rather than the native artery.  The last surgical revision procedure for steal is proximalization of arterial inflow (PAI). In this procedure, the vein is ligated distal to the original anastomosis site and flow is re-established through the fistula with a PTFE interposition graft anastomosed end-to-side with the more proximal axillary artery and end-to-end with the distal vein. Similar to RUDI, PAI increases the length and decreases the diameter of the outflow conduit. Since the axillary artery has a larger diameter than the brachial artery, there is a less significant pressure drop across the arterial anastomosis site and less steal. PAI allows for preservation of native artery's continuity and does not require vein harvest.  Difficulties with PAI arise when deciding the length of the interposition graft to balance AV flow with distal arterial flow. 2. Ischemic Monomelic Neuropathy Definition Ischemic monomelic neuropathy (IMN) is a rare but serious form of steal that involves nerve ischemia. Severe sensorimotor dysfunction is experienced immediately after AV access creation. Etiology IMN affects blood flow to the nerves, but not the skin or muscles because peripheral nerve fibers are more vulnerable to ischemia. Incidence and Risk Factors IMN is very rare; it has an estimated incidence of 0.1-0.5% of AV access creations.6 IMN has only been reported in brachial artery-based accesses, since the brachial artery is the sole arterial inflow for distal arteries feeding all forearm nerves. IMN is associated with diabetes, peripheral vascular disease, and preexisting peripheral neuropathy that is associated with either of the conditions. Patient Presentation Symptoms usually present rapidly, within minutes to hours after AV access creation. The most common presenting symptom is severe, constant, and deep burning pain of the distal forearm and hand. Patients also report impairment of all sensation, weakness, and hand paralysis. Diagnosis of IMN can be delayed due to misattribution of symptoms to anesthetic blockade, postoperative pain, preexisting neuropathy, a heavily bandaged arm precluding neurologic examination. Treatment Treatment is immediate ligation of the AV access. Delay in treatment will quickly result in permanent sensorimotor loss.   3. Perigraft Seroma Definition A perigraft seroma is a sterile fluid collection surrounding a vascular prosthesis and is enclosed within a pseudomembrane. Etiology and Incidence Possible etiologies include: transudative movement of fluid through the graft material, serous fluid collection from traumatized connective tissues (especially the from higher adipose tissue content in the upper arm), inhibition of fibroblast growth with associated failure of the tissue to incorporate the graft, graft “wetting” or kinking during initial operation, increased flow rates, decreased hematocrit causing oncotic pressure difference, or allergy to graft material. Seromas most commonly form at anastomosis sites in the early postoperative period. Overall seroma incidence rates after AV graft placement range from 1.7–4% and are more common in grafts placed in the upper arm (compared to the forearm) and Dacron grafts (compared to PTFE grafts).7-9 Patient Presentation and Workup Physical exam can show a subcutaneous raised palpable fluid mass Seromas can be seen with ultrasound, but it is difficult to differentiate between the types of fluid around the graft (seroma vs. hematoma vs. abscess) Indications for Treatment Seromas can lead to wound dehiscence, pressure necrosis and erosion through skin, and loss of available puncture area for hemodialysis Persistent seromas can also serve as a nidus for infection. The Kidney Disease Outcomes Quality Initiative (KDOQI) guidelines10 recommend a tailored approach to seroma management, with more aggressive surgical interventions being necessary for persistent, infected-appearing, or late-developing seromas.   Treatment The majority of early postoperative seromas are self-limited and tend to resolve on their own Persistent seromas have been treated using a variety of  methods-- incision and evacuation of seroma, complete excision and replacement of the entire graft, and primary bypass of the involved graft segment only. Graft replacement with new material and rerouting through a different tissue plane has a higher reported cure rate and lower rate of infection than aspiration alone.9     4. Infection Incidence and Etiology The reported incidence of infection ranges 4-20% in AVG, which is significantly higher than the rate of infection of 0.56-5% in AVF.11  Infection can occur at the time of access creation (earliest presentation), after cannulation for dialysis (later infection), or secondary to another infectious source. Infection can also further complicate a pre-existing access site issue such as infection of a hematoma, thrombosed pseudoaneurysm, or seroma. Skin flora from frequent dialysis cannulations result in common pathogens being Staphylococcus, Pseudomonas, or polymicrobial species. Staphylococcus and Pseudomonas are highly virulent and likely to cause anastomotic disruption. Patient Presentation and Workup Physical exam will reveal warmth, pain, swelling, erythema, induration, drainage, or pus. Occasionally, patients have nonspecific manifestations of fever or leukocytosis. Ultrasound can be used to screen for and determine the extent of graft involvement by the infection.   Treatments In AV fistulas: Localized infection can usually be managed with broad spectrum antibiotics.  If there are bleeding concerns or infection is seen near the anastomosis site, the fistula should be ligated and re-created in a clean field. In AV grafts: If infection is localized, partial graft excision is acceptable. Total graft excision is recommended if the infection is present throughout the entire graft, involves the anastomoses, occludes the access, or contains particularly virulent organisms Total graft excision may also be indicated if a patient develops recurrent bacteremia with no other infectious source identified. For graft excision, the venous end of the graft is removed and the vein is oversewn or ligated. If the arterial anastomosis is intact, a small cuff of the graft can be left behind and oversewn. If the arterial anastomosis is involved, the arterial wall must be debrided and ligation, reconstruction with autogenous patch angioplasty, or arterial bypass can be pursued. References   1.

  I wanted to try something new today with the podcast. As I've become older and more seasoned, I've had a growing interest in history and the history of things, particularly in medicine. I was never a big history fan in high school. I tolerated it. Don't get me wrong, I had some great teachers of history in high school. But I was much more of a science and math nerd. For a while I've wanted to do an episode about Osgood Schlatter apophysitis, which is such a common problem in pediatrics. I did some digging into some of the historical articles about Osgood Schlatter and thought I'd take an episode to take about some of the interesting things I found and ways it was managed a century ago.

Join Drs. Ashlie Nadler, Jordan Nantais and Graham Skelhorne-Gross as they tackle Cancer Emergencies.   Case 1 - Learning Points: These are complex patients and multidisciplinary care should be provided with input from oncology.  A step-up approach should be used, starting with medical management prior to considering surgery in appropriate patients. Highly selected patients may benefit from surgery, namely those with a high performance status, a prognosis of months if the bowel obstruction was resolved, minimal carcinomatosis, and a single transition point. Diversion, bypass, or resection are all options, but a patient's capacity to heal related to recent systemic therapy needs to be taken into account.  Consent for surgery should focus on goals of care, quality of life, and achievable outcomes, and highlight the inherent risk in patients with advanced disease and a limited lifespan.  Case 2 - Learning Points: Colorectal malignancy is an exceedingly common cause of general surgical emergency and requires a thoughtful, systematic approach The role of stenting as a bridge to surgery in obstructing distal colon malignancy is somewhat controversial but can help to avoid permanent stomas; however there is some potential risk of perforation and possibly disease recurrence Treatment decisions should take place in the context of an informed discussion with the patient and consideration of both quantity and quality of life whenever possible Consistent involvement of a multidisciplinary team, including radiology, enterostomal therapy, and surgical oncology can be extremely useful in guiding complex decisions References: Shariff F, Bogach J, Guidolin K, Nadler A.

Recommendation  1: Given  that  most  patients  with  acute  or subacute  low  back  pain  improve  over  time  regardless  of  treat-ment,  clinicians  and  patients  should  select  nonpharmacologic treatment  with  superficial  heat  (moderate-quality  evidence),  massage,  acupuncture,  or  spinal  manipulation  (low-quality  evidence). If  pharmacologic  treatment  is  desired,  clinicians  and  patients should  select  nonsteroidal  anti-inflammatory  drugs  or  skeletal muscle  relaxants  (moderate-quality  evidence).  (Grade:  strong recommendation) Recommendation  2: For  patients  with  chronic  low  back  pain, clinicians  and  patients  should  initially  select  nonpharmacologic treatment  with  exercise,  multidisciplinary  rehabilitation,  acupuncture,  mindfulness-based  stress  reduction  (moderate-quality  evidence),  tai  chi,  yoga,  motor  control  exercise,  progressive relaxation,  electromyography  biofeedback,  low-level  laser therapy,  operant  therapy,  cognitive  behavioral  therapy,  or  spinal manipulation  (low-quality  evidence).  (Grade:  strong recommendation) Recommendation  3: In  patients  with  chronic  low  back  pain  who have  had  an  inadequate  response  to  nonpharmacologic  therapy, clinicians  and  patients  should  consider  pharmacologic  treatment with  nonsteroidal  anti-inflammatory  drugs  as  first-line  therapy,  or tramadol  or  duloxetine  as  second-line  therapy.  Clinicians  should only  consider  opioids  as  an  option  in  patients  who  have  failed  the aforementioned  treatments  and  only  if  the  potential  benefits  out-weigh  the  risks  for  individual  patients  and  after  a  discussion  of known  risks  and  realistic  benefits  with  patients.  (Grade:  weak  recommendation,  moderate-quality  evidence) Low  back  pain  is  one  of  the  most  common  reasons for  physician  visits  in  the  United  States.  Most  Americans  have  experienced  low  back  pain,  and  approximately  one  quarter  of  U.S.  adults  reported  having  low back  pain  lasting  at  least  1  day  in  the  past  3  months  (1).Low  back  pain  is  associated  with  high  costs,  including those  related  to  health  care  and  indirect  costs  from missed  work  or  reduced  productivity  (2).  The  total  costs attributable  to  low  back  pain  in  the  United  States  were estimated  at  $100  billion  in  2006,  two  thirds  of  which were  indirect  costs  of  lost  wages  and  productivity  (3).Low  back  pain  is  frequently  classified  and  treated on  the  basis  of  symptom  duration,  potential  cause, presence  or  absence  of  radicular  symptoms,  and  corresponding  anatomical  or  radiographic  abnormalities. Acute  back  pain  is  defined  as  lasting  less  than  4  week   Chou R, Deyo R, Friedly J, Skelly A, Hashimoto R, Weimer M, Fu R, Dana T, Kraegel P, Griffin J, Grusing S, Brodt ED.

Does smoking cause lung cancer? How could you ever know? The second in a three-part series on causality, I’m joined by Dr. Shoshana Herzig to discuss how Austin Bradford Hill and Richard Doll set out to try and answer this question -- and along the way revolutionized the way we think about what causes disease. In this episode, we’ll talk about the first double-blinded randomized controlled trial, the long shadow of tuberculosis, and why epidemiology is beautiful.

Somewhat ironic that women report more psychological stress but that men die on average 7 years earlier Things that reliably trigger physiological stress:  Demands >>> Resources Unpredictability Uncontrollability Novelty Learning on stress is U shaped curve A little stress helps things stick more As stress increases harder to draw  Some suggested sex differences: In general women have higher baseline HR than men (despite this, women are believed to have a higher parasympathetic baseline tone) Triggers: Men may be more vulnerable to stressors that trigger dominancy/hierarchy Women may be more vulnerable to stressors that trigger social isolation Free Cortisol is the active form and men appear to have higher free cortisol levels Women may be more sensitive to acth- similar cortisol level with less trigger.

Children the world over are fascinated with what can possibly “fit” in their orifices.  Diagnosis is often delayed.  Anxiety abounds before and during evaluation and management.     Most common objects:1,2 Food Coins Toys Insects Balls, marbles Balloons Magnets Crayon Hair accessories, bows Beads Pebbles Erasers Pen/marker caps Button batteries Plastic bags, packaging Non-pharmacologic techniques Set the scene and control the environment.  Limit the number of people in the room, the noise level, and minimize “cross-talk”.  The focus should be on engaging, calming, and distracting the child. Quiet room; calm parent; “burrito wrap”; guided imagery; have a willing parent restrain the child in his or her lap – an assistant can further restrain the head. Procedural Sedation Most foreign bodies in the ear, nose, and throat in children can be managed with non-pharmacologic techniques, topical aids, gentle patient protective restraint, and a quick hand.  Consider sedation in children with special health care needs who may not be able to cooperate and technically delicate extractions.  Ketamine is an excellent agent, as airway reflexes are maintained.3  Remember to plan, think ahead: where could the foreign body may be displaced if something goes wrong?  You may have taken away his protective gag reflex with sedation.  Position the child accordingly to prevent precipitous foreign body aspiration or occlusion. L’OREILLE – DAS OHR – вухо – THE EAR – LA OREJA – 耳 – L'ORECCHIO Essential anatomy: The external auditory canal. Foreign bodies may become lodged in the narrowing at the bony cartilaginous junction.4  The lateral 1/3 of the canal is flexible, while the medial 2/3 is fixed in the temporal bone – here is where many foreign bodies are lodged and/or where the clinician may find evidence of trauma.  Pearls: Ask yourself: is it graspable or non-graspable?5 Graspable: 64% success rate, 14% complication rate Non-graspable: 45% success rate, 70% complication rate5 If there is an insect in the external auditory canal, kill it first. They will fight for their lives if you try to dismember or take them out.  “In the heat of battle, the patient can become terrorized by the noise and pain and the instrument that you are using is likely to damage the ear canal.”5,6  Use lidocaine jelly (preferred), viscous lidocaine (2%), lidocaine solution (2 or 4%), isopropyl alcohol, or mineral oil. Vegetable matter? Don’t irrigate it – the organic material will swell against the fixed structure, and cause more pain, make it much harder to extract, and may increase the risk of infection. Pifalls: Failure to inspect after removal – is there something else in there? Failure to assess for abrasions, trauma, infection – if any break in skin, give prophylactic antibiotic ear drops Law of diminishing returns: probability of successful removal of ear foreign bodies declines dramatically after the first attempt   LE NEZ – DIE NASE – ніс – THE NOSE – LA NARIZ – 鼻 – IL NASO Essential anatomy: Nasopharyngeal and tracheal anatomy. Highlighted areas indicate points at which nasal foreign bodies may become lodged.4 Pearls: Consider using topical analgesics and vasoconstrictors to reduce pain and swelling – and improve tolerance of/cooperation with the procedure. Use 0.5% oxymetolazone (Afrin) spray and a few drops of 2 or 4%   Pros: as above.  Cons: possible posterior displacement of the foreign body.7 Be ready for the precipitous development of an airway foreign body Pitfalls: Beware of unilateral nasal discharge in a child – strongly consider retained foreign body.8 Do not push a foreign body down the back of a patient's throat, where it may be aspirated into the trachea. Be sure to inspect the palate for “vacuum effect”: small or flexible objects may be found on the roof of the mouth, just waiting to be aspirated.   LA GORGE – DER HALS – горло – THE THROAT – LA GARGANTA – 喉 – LA GOLA Before we go further – Remember that a foreign body in the mouth or throat can precipitously become a foreign body in the airway.  Foreign body inhalation is the most common cause of accidental death in children less than one year of age.9,10 Go to BLS maneuvers if the child decompensates. Infants under 1 year of age – back blows: head-down, 5 back-blows (between scapulae), 5 chest-thrusts (sternum).  Reassess, repeat as needed. Children 1 year and up, conscious – Heimlich maneuver: stand behind patient with arms positioned under the patient’s axilla and encircling the chest. The thumb side of one fist should be placed on the abdomen below the xiphoid process. The other hand should be placed over the fist, and 5 upward-inward thrusts should be performed. This maneuver should be repeated if the airway remains obstructed.  Alternatively, if patient is supine, open the airway, and if the object is readily visible, remove it.  Abdominal thrusts: place the heel of one hand below the xiphoid, interlace fingers, and use sharp, forceful thrusts to dislodge.  Be ready to perform CPR. Children 1 year and up, unconscious – CPR: start CPR with chest compressions (do not perform a pulse check). After 30 chest compressions, open the airway. If you see a foreign body, remove it but do not perform blind finger sweeps because they may push obstructing objects further into the pharynx and may damage the oropharynx.  Attempt to give 2 breaths and continue with cycles of chest compressions and ventilations until the object is expelled. Chest films are limited: 80% of airway foreign bodies are radiolucent.11  Look for unilateral hyperinflation on expiratory films: air trapping.  Essential anatomy: Most esophageal foreign bodies in children occur at the level of the thoracic inlet / cricopharyngeus muscle (upper esophageal sphincter).  Other anatomically narrow sites include the level of the aortic arch and the lower esophageal sphincter. Coin en face – in the esophagus – lodged at the thoracic inlet.12  The pliable esophagus accommodates the flat coin against the flat aspect of the vertebra.11 Beware the “double-ring” sign: this is a button battery13 This is an emergency: the electrolyte-rich mucosa conducts a focal current from the narrow negative terminal of the battery, rapidly causing burn, necrosis, and possibly perforation.  Emergent removal is required. Button batteries that have passed into the stomach do not require emergent intervention – they can be followed closely. Not a button battery, not a sharp object, not a long object? If there is no obstruction, consider revaluation the next day – may wait up to 24 hours for passage.14  Sharieff et al.15 found that coins found in the mid to distal esophagus within 24 hours all passed successfully. What conditions prompt urgent removal? Size Infants: objects smaller than 2 cm wide and 3 cm long will likely pass the pylorus and ileocecal valve10 Children and adults: objects smaller than 2 cm wide and 5 cm long will likely pass the pylorus and ileocecal valve9 Character Sharp objects have a high rate of perforation (35%)1 Pearls: History is essential. Believe the parents and assume there is an aspirated/ingested foreign body until proven otherwise. History of choking, has persistent symptoms and/or abnormal xray? Broncoscopy! Cohen et al.16 found that of 142 patients evaluated at a single site university hospital, 61 had a foreign body. Of the 61 patients, 42 had abnormal physical exams and radiographs and 17 had either abnormal physical exams or radiographs, and 2 had normal physical exams and radiographs, but both had a history of persistent cough.  Bottom line: history of choking PLUS abnormal exam, abnormal films, or persistent symptoms, evaluate with bronchoscopy. For patients with some residual suspicion of an aspirated foreign body (mild initial or improving symptoms; possibly abnormal chest x-ray; low but finite risk), consider chest CT with virtual bronchoscopy as a rule-out strategy.17,18 Outpatients who have passed a small and non-concerning object into the stomach or beyond: serial exams and observing stools – polyethylene glycol 3350 (MiraLAX) may be given for delayed passage19 Pifalls: A single household magnet will likely pass through the GI tract, with the aforementioned dimensional caveats. Two or more magnets, however, run the risk of attraction and trans-bowel wall pressure necrosis. Not all magnets are created equal. Neodymium magnet toys (“buckyballs”) were recalled in 2014 (but are still out there!) due to their highly attractive nature.  These magnets must be removed to avoid bowel wall ischemia. 19–21 Patients should avoid wearing belt buckles or metallic buttons in case of single magnet ingestion while waiting for the single magnet to pass DES OUTILS DU MÉTIER – DIE HANDWERKSZEUG – Знаряддя праці – TOOLS OF THE TRADE – LAS HERRAMIENTAS DEL OFICIO – GLI ATTREZZI DEL MESTIERE –  仕事のツール It’s best to keep your armamentarium as large as you can.   Curette A small foreign body in the lateral 1/3 of the auditory canal may be amenable to a simple curettage.  Hair beads (if the central hole is accessible) may be manipulated out with the angled tip of a rigid curette.  Steady the operating hand by placing your hypothenar eminence on the child’s zygoma or temporal scalp, to avoid jutting the instrument into the ear canal with sudden movement.  There is a large selection of disposable simple and lighted curettes on the market. Right-angle Hook Various eponymous hooks are available for this purpose; one in popular use is the Day hook, which may be passed behind the foreign body.22  An inexpensive and convenient alternative to the commercially available right-hooks is a home-made version: make your own by straightening out a paperclip and bending it to a right angle23 at 2-3 mm from the end (be sure not to use the type that have a friable shiny metallic finish, as the residue may be left behind in the ear canal).  If it is completely lodged, use of a right-angle hook will likely only cause trauma to the canal. Alligator forceps Alligator forceps are best for grasping soft objects like cotton or paper.  Smooth, round or oval objects are not amenable to extraction with alligator forceps.  When using them, be sure to get a firm, central grip on the object, to avoid tearing it into smaller, less manageable pieces.  Pro tip: Look before you grip! Be careful to visualize the area you are gripping, to avoid pulling on (and subsequently avulsing) soft tissue in the ear canal. Cyanoacrylate (Dermabond®, SurgiSeal®) Apply cyanoacrylate to either side of a long wooden cotton swab (the lecturer prefers the cotton tip side, for improved grip/molding around object).  Immediately apply the treated side to the object in the ear canal in a restrained patient.  Steady the hypothenar eminence on the child’s face to avoid dislodgement of the cotton swab with sudden movement.  Apply the treated swab to the foreign body for 30-60 seconds, to allow bonding.  Slowly pull out the foreign body.  Re-visualize the ear canal for other retained foreign bodies and abrasion or ear canal trauma. Did the cyanoacrylate drip?  Did the swab stick to the ear canal? No problem – use 3% hydrogen peroxide or acetone.24  Pour in a sufficient amount, allow to work for 10 minutes.  Both agents help to dissolve ear wax, the compound, or both.  Repeat if needed to debond the cyanoacrylate from the ear canal.24,25 Irrigation Irrigation is the default for non-organic foreign bodies that are not amenable to other extraction techniques.  Sometimes the object is encased in cerumen, and the only “instrument” that will fit behind the foreign body is the slowly growing trickle of water that builds enough pressure to expulse it.  Do not use if there is any organic material involved: the object will swell, causing much more pain, difficulty in extraction, and possibly setting up conditions for infection. Position the child either prone or supine, gently restrain (as above).  Let gravity work for you: don’t irrigate in decubitus position with the affected ear up.  It may be more accessible to you, but you may never get the foreign body out. To use a butterfly needle: use a small gage (22 or 24 g) butterfly set up, cut off the needle, connect the tubing to a 30 mL syringe filled with warm or room-temperature water. Insert the free end of the tubing gently, and “secure” the tubing with your pinched fingers while irrigating (think of holding an ETT in place just after intubation and before taping/securing the tube).  Gently and slowly increase the pressure you exert as you irrigate. To use an IV or angiocatheter: use a moderate size (18 or 20 g) IV, remove the needle and attach the plastic catheter to a 20 mL syringe, and irrigate as above. Acetone Acetone has been used successfully to remove chewing gum, Styrofoam, and superglue from the ear canal24,26,27  Use in cases where there is no suspicion of perforation of the tympanic membrane. Docusate Sodium (Colace®) Cerumen is composed of sebaceous ad ceruminous secretions and desquamated skin.  Genetic, environmental, and anatomical factors combine to trap a foreign body in the external canal.  Use of a ceruminolytic such as docusate sodium may help to loosen and liberate the foreign body.28  Caveat medicus: Adding docusate sodium will make the object more slippery – this may or may not be an issue given the nature of the foreign body. In the case where loosening the ear wax may aid extraction (and will not cause a slippery mess), consider filling the ear canal will docusate sodium (Colace), having the child lie with the affected side up, waiting 15 minutes, and proceeding.  This is especially helpful when planning for irrigation. Magnets Rare earth magnets (a misnomer, as their components are actually abundant) such as neodymium can be useful in retrieving metallic foreign bodies (e.g. button batteries in the nose or ears).29,30  Magnetic “pick-up tools” – used by mechanics, engineers, and do-it-yourselfers – are inexpensive and readily available in various sizes, shapes, and styles such as a telescoping extender.  Look for a small tip diameter (to fit in the ear canal as well as the nose) and a strong “hold” (at least a 3-lb hold). Alternatively, you may purchase a strong neodymium bar magnet (30- to 50-lb hold) to attach to an instrument such as an alligator forceps, pick-up forceps, or small hemostat (a pacemaker magnet may also work).  The magnetic bar, placed in your palm at the base of the instrument, will conduct the charge (depending on the instrument) and allow you to retrieve many metallic objects.31  Although stainless steel is often said to be “non-magnetic”, it depends on the alloy used, and some may actually respond to the strong rare earth magnet.  Most stainless steel has a minimum of 10.5% chromium, which gives the steel its 'stainless' properties (essentially corrosion resistance).  A basic stainless steel has a “ferritic” structure and is magnetic.  Higher-end stainless steel such as in kitchen cutlery have an “austenitic” structure, with more chromium added, and so less magnetic quality.  (Ironically, the more “economical” instruments in the typical ED suture kit have less chromium, and so are more magnetic – use these with your neodymium bar magnet to conduct the magnetic charge and extract the metallic foreign body.) Bottom line: if it’s metal, it’s worth a try to use a magnet.  Even if the metal is very weakly magnetic, the strong neodymium magnet may still be able to exert a pull on it and aid in extraction. Snare Technique A relatively new method, described by Fundakowski et al.32 consists of using a small length of 24-gauge (or similar) wire (available inexpensively online, and kept in your personal “toolkit”; see Appendix B below) to make a loop that is secured by a hemostat (the 24-gauge wire is easily cut into strips with standard trauma scissors).  After treatment with oxymetolazone (0.05%) and lidocaine (1 or 2%) topically, the loop is passed behind the foreign body (in the case report, a button battery).  Pull the loop toward you until you feel that it is sitting up against the button battery.  Now, turn the hemostat 90° to improve your purchase on the foreign body.  Pull gently out.  This technique is especially useful when the foreign body has created marked edema, either creating a vacuum effect or making it difficult for other instruments to pass. Balloon Catheters (Katz extractor®, Fogarty embolectomy catheter) Small-caliber devices (5, 6, or 8 F) originally designed for use with intravascular or bladder catheterization may be used to extract foreign bodies from the ear or nose.7,33  A catheter designed specifically for foreign body use is the Katz extractor.  Inspect the ear or nose for potential trauma and to anticipate bleeding after manipulation (especially the nose).  Deflate the catheter and apply surgical lubricant or 2% lidocaine jelly. Insert the deflated catheter and gently pass the device past the foreign body.  Inflate the balloon and slowly pull the balloon and foreign body out.  Re-inspect after extraction. NB, from the manufacturer of the Katz extractor, InHealth: “the Katz Extractor oto-rhino foreign body remover is intended principally for extraction of impacted foreign bodies in the nasal passages. This device may also be used in the external ear canal, based upon clinical judgment.” Mother’s kiss The mother’s kiss was first described in 1965 by Vladimir Ctibor, a general practitioner from New Jersey.34 “The mother, or other trusted adult, places her mouth over the child’s open mouth, forming a firm seal as if about to perform mouth-to-mouth resuscitation. While occluding the unaffected nostril with a finger, the adult then blows until feeling resistance caused by closure of the child’s glottis, at which point the adult gives a sharp exhalation to deliver a short puff of air into the child’s mouth. This puff of air passes through the nasopharynx, out through the non-occluded nostril and, if successful, results in the expulsion of the foreign body. The procedure is fully explained to the adult before starting, and the child is told that the parent will give him or her a “big kiss” so that minimal distress is caused to the child. The procedure can be repeated a number of times if not initially successful.”34 Positive Pressure Ventilation with Bag Valve Mask This technique is an approximation of the above mother’s kiss technique – useful for unwilling parents or unsuccessful tries.10,25  The author prefers to position the child sitting up.  A self-inflating bag-mask device is fitted with a very small mask: use an abnormally small mask (otherwise inappropriately small for usual resuscitative bag-mask ventilation) to fit over the mouth only.  Choose an infant mask that will cover the child’s mouth only.  Occlude the opposite nostril with your finger while you form a tight seal with the mask around the mouth. Deliver short, abrupt bursts of ventilation through the mouth – be sure to maintain good seals with the mask and with your finger to the child’s nostril – until the foreign body is expulsed through the affected nostril. Beamsley Blaster (Continuous Positive Pressure) Technique For the very uncooperative child with a nasal foreign body amenable to positive pressure ventilation who fails the mother’s kiss and bag-mask technique, a continuous positive pressure method may be used. Connect one end of suction tubing to the male adaptor (“Christmas tree”) of an air or oxygen source.  Connect the other end of the suction tubing to a male-to-male adaptor (commonly used for chest tube connections or connecting / extending suction tubes).  Insert the end of the device into the child’s unaffected nostril.  The air flow will deliver positive pressure ventilation continuously. With this technique there is a theoretical risk of barotrauma to the lungs or tympanic membranes.  However, there is only one case reported in the literature of periorbital subcutaneous emphysema. To minimize this risk, some authors recommend limiting to a maximum of four attempts using any positive pressure method.10 Nasal speculum Optimize your visualization with a nasal speculum.  The nostrils, luckily, will accommodate a fair amount of distention without damage.  Hold the speculum vertically to avoid pressure on and damage to the vessel-and-nerve-rich nasal septum.  Hold the handle of the speculum in the palm of your hand comfortably and while placing your index finger on the patient’s ala.  This will help to control the speculum and your angle of sight. Your other hand is then free to use a hook or other tool for extraction. Lighting is especially important when using the nasal speculum: a focused procedure light or head lamp is very helpful.  The author keeps a common camping LED headlamp in his bag for easy access. Suction tips / catheters Various commercial and non-commercial suction devices are on the market for removal of foreign bodies.  All connect to wall suction, and vary by style, caliber of suction, and tip end interface.  A commonly available suction catheter is the Frazier suction tip (right), a single-use device used in the operating room. A modification to suction can be made with the Schuknecht foreign body remover (left; not to be confused with the suction catheter of the same name): a plastic cone-shaped tip placed on the end of the suction catheter to increase vacuum surface area and seal.  Laryngoscope and Magill Forceps If a child aspirates and occludes his airway, return to BLS maneuvers (as above).  If the child becomes obtunded, use direct laryngoscopy to visualize the foreign body and remove with the Magill forceps.  Hold the laryngoscope in your left hand as per usual.  Hold the Magill forceps in your right hand – palm side down – to grasp and remove the foreign body.  Take-home Points  Beware the “vacuum palate”: a flat (especially clear plastic) foreign body hiding on the palate Take seriously the complaint of foreign body without obvious evidence on initial inspection – believe that something is in there until proven otherwise Control the environment, address analgesia and anxiolysis, have a back-up plan Motto Like a difficult airway: plan through the steps MERCI – DANKE – Дякую – THANK YOU – GRACIAS –  ありがとう— GRAZIE Appendix A: Prevention At the end of the visit, after some rapport has been established, counsel the caregivers about age-appropriate foods and “child-proofing” the home.  This is a teachable moment – and only you can have this golden opportunity! Age-appropriate foods 0-6 months: breastmilk or formula 6-9 months: introduce solid puree-consistency foods 9-12 months: small minced solids that require no chewing (well cooked, soft, chopped foods) Although molars (required for chewing) erupt around 18 months, toddlers need to develop coordination, awareness to eat hard foods that require considerable chewing. Not until 4 years of age (anything that requires chewing to swallow):             Hot dogs             Nuts and seeds             Chunks of meat or cheese             Whole grapes             Hard or sticky candy             Popcorn             Chunks of peanut butter             Chunks of raw vegetables             Chewing gum Child-proofing the home Refer parents to the helpful multi-lingual site from the American Academy of Pediatrics: http://www.healthychildren.org/English/safety-prevention/at-home/Pages/Childproofing-Your-Home.aspx An abbreviated list: use age-appropriate toys and “test” them out before giving them to your child to verify that there are no small, missing, or loose parts.  Secure medications, lock up cabinets (especially with chemicals), do not store chemicals in food containers, secure the toilet bowl, and unplug appliances. Parents should understand that “watching” their child alone cannot prevent foreign body aspiration: a recent review found that in 84.2% of cases, incidents resulting in an airway foreign body occurred in the presence of an adult.35 Best overall tip: get down on all fours and inspect your living area from the child’s perspective.  It is amazing what you will find when you are least expecting it. Appendix B: The Playbook's ENT Foreign Body Toolkit Although your institution should supply you with what you need to deal with routine problems, we all struggle with having just what we need when we need it.  High-volume disposable items such as cyanoacrylate (Dermabond), curettes, supplies for irrigation, alligator forceps, and the like certainly should be supplied by the institution.  However, some things come in very handy as our back-up tools. NB: we should be cognizant of the fact that tools that must be sterilized or autoclaved are not good candidates for our personal re-usable toolkits. These items can all be found inexpensively – shop around online, or in home improvement stores: Head lamp, LED camping style: $5-15 Neodymium magnet “pick-up tool”: $5-15 Neodymium bar magnet: $6-20 Wire, 24-gauge, spool of 25 yards (for snare technique): $6 Day hook: $15-20 References Chapin MM, Rochette LM, Annest JL, Haileyesus T, Conner KA, Smith GA.

Multisystem Trauma in Children, Part Two: Massive Transfusion, Trauma Imaging, and Resuscitative Pearls

Pediatric Emergency Playbook

A 5-year-old boy was playing with his older brother in front of their home when he was struck by a car. He sustained a femur fracture, splenic laceration, and blunt head trauma – the so-called Waddell’s triad. On arrival, he was in compensated shock, with tachycardia. He decompensates and needs blood. How do we manage his hemodynamics and when do we perform massive transfusion? Pediatric Massive Transfusion 40 mL/kg of blood products given at any time within the first 24 hours. Adolescents and Adult Massive Transfusion 6-8 units of packed red blood cells (PRBCs) Adults have about 5 L of circulating blood. Not including plasma, one could replace all circulating erythrocytes with about 10 units of PRBCS The best ratio of PRBCs:Plasma:Platelets is unknown, but consensus is 1:1:1. 1 unit of PRBCS is typically 300 mL of volume. The typical initial transfusion of PRBCs in children is 10 mL/kg. Massive transfusion in children is defined as 40 mL/kg of any blood product. Once you start to give a child with major trauma the second 10 mL/kg dose of PRBCs – start thinking about other blood components, and ask yourself whether you should initiate your massive transfusion protocol. The goal is to have the products ready to use in the case of the dynamic trauma patient. The Thromboelastogram (TEG) Direct measures the four components of clot formation. When there is endolethial damage and bleeding, the sequence that your body takes to address it is as follows:  Platelets migrate and form a plug Clotting factors aggregate and reinforce the platelets Fibrin arrives an acts like glue Other cells migrate and support the clot. R time – reaction time – the initial line in the tracing that shows time to beginning of clot formation. Treated with platelets K factor – kinetics of the clot –how much the clot allows the pin to move, or the amplitude. Treated with cryoprecipitate Alpha angle – the slope between the R and K measurements – reflects how quickly the fibrin glue is working. Treated with cryoprecipitate Ma – maximum amplitude – reflects the overall strength of the clot. Treated with platelets LY30 – the clot lysis at 30 min – is the decrease in strength of the clot’s amplitude at 30 min. Treated with an antifibrinolytics (tranexamic acid) Shape Recognition Red wine glass: a normal tracing with a normal reaction time and a normal amplitude. That patient just needs support and monitoring. Champagne glass: a coagulopathic TEG tracing – thinned out, with less amplitude. This patient needs specific blood products. Puffer fish or blob: a hyperfibrinolytic tracing. That patient will needs clot-stablizer. TEG – like the FAST – can be repeated as the clinical picture changes. The Trauma Death Spiral Lethal triad of hypothermia, acidosis, and coagulopathy. Keep the patient perfused and warm. Each unit of PRBCs contains 3 g citrate, which binds ionized calcium, causing hypotension. In massive transfusion, give 20 mg/kg of calcium chloride, up to 2 g, over 15 minutes. Calcium chloride is preferred, as it is ionically readily available – just use a larger-bore IV and watch for infiltration. Calcium gluconate could be used, but it requires metabolism into a bioavailable source of calcium. Prothrombin complex concentrate (PCC) Prothrombin complex concentrate (PCC) is derived from pooled human plasma and contains 25-30 times the concentration of clotting factors as FFP. Four-factor PCCs contain factors II, VII, IX and X, while 3-factor PCCs contain little or no factor VII. The typical dose of PCC is 20-50 units/kg In the severely hemorrhaging patient – you don’t have time to wait for the other blood products to thaw – PCC is a powder that is reconstituted instantly at the bedside. Tranexamic acid (TXA) Tranexamic acid (TXA), is an anti-fibrinolytic agent that functions by stopping the activation of plasminogen to plasmin, and the degradation of fibrin. The Clinical Randomisation of an Antifibrinolytic in Significant Hemorrhage (CRASH-2) investigators revealed a significant decrease in death secondary to bleeding when TXA was administered early following trauma. Based on the adult literature, one guideline is to give 15 mg/kg loading dose of TXA with a max 1 g over 10 minutes followed by 2 mg/kg/h for at least 8 h or until bleeding stops. Resuscitative Pearls Our goal here is damage control. Apply pressure whenever possible. Otherwise, resuscitate, identify the bleeding source, and slow or stop the bleeding with blood products or surgery. How Children are Different in Trauma In adults, we speak of “permissive hypotension” (also called “balanced resuscitation” or “damage control resuscitation”). The idea is that if we bring the adult patient’s blood pressure up to normal, we may be promoting clot rupture. To avoid this, we target a MAP of 65 and look for clinical signs of sufficient perfusion. Adults tolerate hypotension relatively well, and is sufficient until we send them to the OR or interventional radiology suite. In children, this is simply not the case. Hypotension in children is a sign of pre-arrest. Remember, they compensate with an increased systemic vascular resistance and tachycardia to maintain blood pressure. We should not allow children to become hypotensive – severe tachycardia alone should prompt us to resuscitate. In other words, permissive hypotension is not permissible for children. FAST is not sensitive enough to rule-out abdominal trauma. Fox et al in Academic Emergency Medicine found a sensitivity of 52%; with a 95% confidence interval [CI] = 31% to 73%. Often children even with high-grade splenic and liver lacerations can be managed non-operatively. If they are supported adequately, they are observed in the ICU and can avoid surgery in many cases. Unfortunately, a negative FAST cannot help with detecting or grading the laceration for non-operative management. In other words, feel free to use ultrasound – especially for things that we in the ED will react to and intervene on – but CT may help to manage the traumatized child non-operatively. General Guideline for Imaging in Pediatric Trauma CT Head and Neck, non-contrast: in concerning mechanisms of injury, patients that are difficult to assess (especially those under 3 months), those with a GCS of 13 or lower. CT Chest, IV contrast: for suspicion of vascular injury that needs exploration, especially in penetrating trauma. Otherwise, chest xray will tell you everything you need to know in children – especially in blunt trauma. Hemo or pneumothoraces are readily picked up by US or CXR. Rib fractures on CXR predict pulmonary contusions. If you are concerned about great vessel injury, then CT Chest may be helpful; otherwise consider omitting it. CT Abdomen and Pelvis, IV contrast: helpful in grading splenic and liver lacerations with goal to manage non-operatively. Abdominal tenderness to palpation, significant bruising, or a seat belt sign are concerning and would generally warrant a CT. Also, consider in liver function test abnormalities, or hematuria. Extremity injuries: in general can be evaluated with physical exam and plain films. However, some injuries in high-risk anatomically complex areas such as the hand and wrist, tibial plateau, and midfoot may be missed by plain films, and CT may be helpful here. Remember: you can help to mitigate post-traumatic stress and risk for adult healthcare aversion. Summary Massive transfusion in children is at 40 mL/kg of total blood products. Think about it if you are giving your second transfusion to the traumatized child. Do everything you can to support perfusion and avoid the death spiral of hypothermia, coagulopathy, and acidosis. Keep the child perfused with blood as needed, correct coagulopathy, avoid too much crystalloid, and make sure to use the least high-tech of all of these interventions – keep him dry and covered with warm blankets. Do a careful physical exam, and use CT selectively with an end-point in mind – the default is not the pan-scan – evaluate possible injuries depending on your suspicions from history, physical, and lab tests. Become familiar with the relatively new modalities in trauma such as TXA, cryoprecipitate and the emerging technology of thromboelestogram – red wine is good for you, champagne is weak, and a puffer fish is trouble.
