Core EM - Emergency Medicine Podcast

A discussion with Drs. McNamara and Leifer on the essentials and beyond of debriefing Hosts: Brian Gilberti, MD Audrey Tse, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Debriefing.mp3 Download One Comment Tags: Resuscitation, Simulation Show Notes TAKE HOME POINTS Debriefing after a clinical case in the ED is a way to have an interprofessional, reflective conversation with a focus on improving for the next patient.  We can debrief routine cases, challenging cases, or even cases that go well. Follow a structure when leading a debrief. The prebrief sets ground rules and informs the team that the debrief is optional and will only take 3-5 minutes. Introduce names and roles Then give a one-liner about what happened in the case, followed by a plus/ delta: address  what went well and why, then how to improve Finally, wrap up with take home points Pitfalls to watch out for in clinical debriefing include: Avoid siloing or alienating any learners.  Learn from all your colleagues on your team- it’s less about medicine and more about interprofessional and systems issues Don’t pick on individual performance.  It’s not about shaming- it’s about improving patient care Avoid “guess what I’m thinking” questions; ask real questions Proceed with caution in order to dampen or avoid psychological trauma and second victim syndrome.  The learner may ask “was this my fault?”; we never want a learner to feel this way.  Ask, what systems supported or did not support you today?  Talk about what happened.  Avoid shame and blame. Have the right values and do it for the right reasons. ADDITIONAL TOOLS PEARLS Debriefing Tool INFO Model: GUESTS Dr. Shannon McNamara completed residency in Emergency Medicine at Temple University hospital and fellowship in Medical Simulation at Mount Sinai St. Lukes-Roosevelt.

Croup is a common viral infection that strikes children, leading to a barking cough and inspiratory stridor. The hosts unpack its causes, primarily the parainfluenza virus, and discuss the typical presentation of croup, including the alarming 'steeple sign' seen on X-rays. They also emphasize the critical importance of assessing symptom severity through tools like the Westley Croup Score and offer management strategies for mild to severe cases. Learn how to navigate this challenging condition in young patients!

A look at this deadly mucocutaneous reaction and how to best manage these patients in the ED https://media.blubrry.com/coreem/content.blubrry.com/coreem/SJS.mp3 Download Leave a Comment Tags: Critical Care, Dermatology Show Notes Episode Produced by Audrey Bree Tse, MD Rash with dysuria should raise concern for SJS with associated urethritis Dysuria present in a majority of cases SJS is a mucocutaneous reaction caused by Type IV hypersensitivity Cytotoxic t-lymphocytes apoptose keratinocytes → blistering, bullae formation, and sloughing of the detached skin Disease spectrum SJS = <10% TBSA TEN = >30% TBSA SJS/ TEN Overlap = 10-30% TBSA Incidence is estimated at around 9 per 1 million people in the US Mortality is 10% for SJS and 30-50% for TEN Mainly 2/2 sepsis and end organ dysfunction. SJS can occur even without a precipitating medication Infection can set it off especially in patients with risk factors including HIV, lupus, underlying malignancy, and genetic factors SATAN for the most common drugs Sulfa, Allopurinol, Tetracyclines, Anticonvulsants, and NSAIDS Anti-epileptics include carbamazepine, lamictal, phenobarb, and phenytoin Can have a curious course Hypersensitivity reaction can develop while taking medication, or even one to four weeks after exposure In pediatric population, mycoplasma pneumonia and herpes simplex have been identified as precipitating infections Patients often have a prodrome 1-3 days prior to the skin lesions appearing May complain of fever, myalgias, headaches, URI symptoms, and malaise Rash may be the sole complaint Starts as dark purple or erythematous lesions with purpuric centers that progress to bullae Skin surrounding the lesions detaches from the dermis with just light pressure (Nikolsky Sign) Up to 95% of patients will have mucous membrane lesions ~85% will have conjunctival lesions Symptoms: Burning or itching eyes, a cough or sore throat, pain with eating, pain with urinating or defecating Source: JAMA Dermatol. 2017 Differential Diagnosis: SSSS, autoimmune bullous diseases, bullous fixed drug eruption, erythema multiforme, thermal burns, phototoxic reactions, and TSS SJS is a clinical diagnosis Basic workup: CBC, chemistry panel, LFTs, and a UA Treatment Supportive care IV fluid repletion guided by TBSA affected, as well as electrolyte, protein, and energy supplementation Consider protecting airway if significant oral mucosal involvement Stop the offending agent (if there is one) Advanced wound care and pain control Consults: Derm to do a biopsy, +/- ophthalmology, gyn / urology to prevent strictures or contractures Consider transferring to a burn center Dispo: Low threshold for ICU admission SCORTEN ( max of 7 points) 1 point each for Age over 40 Current cancer >30% body surface area affected HR >120 BUN >28 Glucose >240 Bicarb <20 Score of 2 points or higher should -> ICU Take Home Points SJS may begin like the flu, with lesions appearing 1-3 days after the prodrome starts Have to have a high suspicion for SJS because it is deadly. It’s a clinical diagnosis — derm biopsy is supportive A thorough history and physical exam are key.  Remember the characteristic rash and bullae, and always look in the mouth and eyes.  Ask about dysuria, sore throat, and eye irritation, as well as preceding medications or infections.  Think SATAN! Prompt supportive care focused on ABCs and IVF repletion are critical.  These patients can get sick really fast, so consider an ICU or burn unit.

A look at the opioid epidemic and what ED providers can do to combat this formidable foe. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Opioid_Epidemic.mp3 Download Leave a Comment Tags: Opioid Dependence, Opioid Free ED Show Notes Consider alternatives to opiates for acute pain NSAIDs Subdissociative ketamine Nerve blocks Curb misuse and diversion through prescribing a short supply and perform I-STOP checks Narcan is not just for acute overdose treatment by EMS or within the ED anymore We can equip patients, family members and friends with Narcan kits prior to discharge In New York state, can prescribe Narcan to patients with near fatal overdoses or who screen positive for an opioid use disorder Intranasal formulation is cheaper and more commonly prescribed than IM Buprenorphine induction can be done in the ED for patients in active withdrawal, as calculated by the COWS score. MDcalc calculator: https://www.mdcalc.com/cows-score-opiate-withdrawal Providers do not need an X-waiver to give a dose of Buprenorphine in the ED for 3 days Home induction can be considered for patients not actively withdrawing but would like to enter medication assisted treatment Some considerations: Contraindicated in patients with severe liver dysfunction and with hypersensitivity reaction to drug Oversedation can occur with concurrent use of benzodiazepines and alcohol Will precipitate withdrawal if concurrently using full opioid agonists Longitudinal care has to be established for patients started on Buprenorphine SAMHSA’s Buprenorphine practitioner locator site: https://www.samhsa.gov/medication-assisted-treatment/practitioner-program-data/treatment-practitioner-locator Buprenorphine Induction Pamphlet Read More

In this episode, we discuss Boxer's fractures and how to best manage them in the ED. https://media.blubrry.com/coreem/content.blubrry.com/coreem/Boxer_s_Fracture_eq.m4a Download One Comment Tags: Orthopedics, Trauma Podcast Video https://youtu.be/UreET5eLHas Show Notes Background: 40% of all hand fractures A metacarpal fracture can occur at any point along the bone (head, neck, shaft, or base) “Boxer’s” fractures classically at neck Most common mechanism: direct axial load with a clenched fist Most common metacarpal injured is the 5th A majority of these injuries are isolated injuries, closed and stable Examination: Ensure that this is an isolated injury May note a loss of knuckle contour or shortening A thorough evaluation of the skin is important Patients may also have fight bites and require irrigation and antibiotics Tender along the dorsum of the affected metacarpal Evaluate the range of motion as the commonly seen shortening results in extension lag For every 2 mm of shortening there is going to be a 7 degree decrease in ability to extend the joint Check rotational alignment of digits with the MCP and PIP at 50% flexion. Partially clench their fist and ensure that the axis of each digit converges near the scaphoid pole / mid wrist Deformity is often seen due to the imbalance of volar and dorsal forces Dorsal angulation AP, lateral and oblique views should be obtained on XR The degree of angulation is estimated with the lateral view NB: Normal angle between the metacarpal head and neck is 15 degrees Management: Most may be splinted with an ulnar gutter splint Must be closed, not significantly angulated, and not malrotated When splinting, place the wrist in slight extension, MCP (knuckles) at 90 degrees and the DIP and PIP in a relaxed, slightly flexed position A closed reduction is indicated if there is significant angulation “20, 30, 40” rule If angulation is more than: 20 in the middle finger metacarpal 30 in the ring finger metacarpal 40 in the pinky finger metacarpal Analgesia with a hematoma block or ulnar nerve block Reduction technique: https://www.aliem.com/2013/01/trick-of-trade-reducing-metacarpal/ Referral: May have mild deformity or decreased functionality and strength in hand grip after this injury Emergent evaluation if: Open fracture Neurovascular compromise Follow up: Refer to hand specialist Within 1 week if fractures of 4thand 5thmetacarpals with angulation 3 to 5 days if the 2ndand 3rd metacarpalsare affected Immobilized for three to four weeks in splint Healing may take up to six weeks Take Home Points: This is one of the most common fractures we will see as emergency physicians When evaluating these patients, ensure that this are no other more severe, life-threatening injuries, and pay particular attention to the skin exam so that you do not miss a fight-bite Reductions may be required if there is significant angulation, which is guided by the 20, 30, 40 rule Finally, emergent specialist evaluation is indicated if there is an open fracture or evidence of neurovascular compromise Read More
