Podcast 659: Racial Bias in Pulse Oximetry
Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: Study in NEJM looked at occult hypoxemia, when oxygen saturation reads at >92% when the actual saturation is <88% Rate of occult hypoxemia was 3 times higher in those who identified as black (12% vs 4%) Keep this disparity in mind when providing care to patients of all backgrounds and incorporate into clinical decision-making References Sjoding MW, Dickson RP, Iwashyna TJ, Gay SE, Valley TS. Racial Bias in Pulse Oximetry Measurement. N Engl J Med. 2020;383(25):2477-2478. doi:10.1056/NEJMc2029240 Summarized by John Spartz, MS3 |...

Emergency Medical Minute
Contributor: Peter Bakes, MD Educational Pearls: Lyme disease gives a single expanding target lesion with central clearing called erythema chronicum migrans Erythema multiforme is another targetoid rash that presents with multiple target lesions Characterized into erythema minor and major based on severity but typically resolves More severe hypersensitivity reactions include Stevens-Johnson Syndrome (<10% skin involvement), or Toxic Epidermal Necrolysis (>30% skin involvement) SJS and TEN is associated with NSAIDS including aspirin, antiemetics like phenergan, anticonvulsants like...

Podcast 655: Hypothermia in Sepsis
Emergency Medical Minute
Contributor: Adam Barkin, MD Educational Pearls: Fever is an adaptive response to infection, but elderly and immunocompromised patients may not be able to mount a hyperthermic response in sepsis Patients with fever in sepsis end up receiving treatment earlier and have better outcomes Hypothermic patients with severe sepsis admitted to the ICU had a 32% mortality versus 21% mortality in those who had a fever on presentation 3-hour sepsis bundle compliance was less frequent in hypothermic patients than in febrile patients (56% versus 71%) Early broad spectrum antibiotics were administered less...

Emergency Medical Minute
Contributor: Aaron Lessen, MD Educational Pearls: Survey study compared depression symptom prevalence in the United States at the beginning of COVID compared to data acquired by a similar survey for 2017-2018 and found it was three-fold higher Mild symptoms: 25% during pandemic; 16% before Moderate: 15% during pandemic; 6% before Moderately Severe symptoms: 8% during pandemic; 2% before Severe symptoms: ~5% during pandemic; 1% before Those with lower income, less savings, and exposure to more stressors were at greater risk for developing depression symptoms References Ettman CK,...

Podcast 653: Nitroglycerin Disimpaction
Emergency Medical Minute
Contributor: Ricky Dhaliwal, MD, JD Educational Pearls: Glucagon administered intravenously has a high rate of adverse events (nausea/vomiting) with very weak evidence NItroglycerin too has very limited evidence but a much better adverse event profile Mix 0.4 mg (1 sublingual tablet) nitro in 10 mL of water and administer orally Nothing beats upper endoscopy for effectiveness but in settings where GI is not immediately available, nitroglycerin may be worth an attempt given its better safety profile to other medications References Arora S, Galich P. Myth: glucagon is an...

Podcast 652: Prosthetic Hip Dislocation
Emergency Medical Minute
Contributor: Jared Scott, MD Educational Pearls: While it is rare to have a native hip dislocation, it is relatively common to dislocate a prosthetic hip The mechanism for dislocation is usually adduction, flexion, and internal rotation the hip which can occur when walking Arthroplasty in the setting of trauma or fracture, posterior approach during surgery, and using a small femoral head increase the likelihood of later dislocation If a patient with a total hip arthroplasty says they were walking and then developed hip pain, do not discount a potential dislocation References Zahar A,...

Educational Pearls:
- Two main differentials for wide complex tachycardia (WCT) include ventricular tachycardia (most common) and supraventricular tachycardia with aberrancy
- Brugada syndrome and Wolff-Parkinson White are potential causes
- Arrhythmogenic right ventricular dysplasia is a rare congenital cause of WCT that should be considered in younger patients presenting with WCT
