Emergency Medical Minute

Contributor: Peter Bakes, MD 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 References B Garner J, M Miller J. . Arrhythm Electrophysiol Rev. 2013;2(1):23-29. doi:10.15420/aer.2013.2.1.23 Katritsis DG, Brugada J. . Arrhythm Electrophysiol Rev. 2020;9(3):155-160....

Podcast 634: D10 for Hypoglycemia show art Podcast 634: D10 for Hypoglycemia

Emergency Medical Minute

Contributor: Dylan Luyten, MD Educational Pearls: D10 may be a better alternative to D50 in correcting hypoglycemia Risks of D50:  Can cause extravasation injury Risk of rebound hypoglycemia D10 does not have the same risks and has no significant difference in reversal time of hypoglycemia compared to D50 References Kiefer MV, Gene Hern H, Alter HJ, Barger JB. . Prehosp Disaster Med. 2014 Apr;29(2):190-4. doi: 10.1017/S1049023X14000284. Epub 2014 Apr 15. PMID: 24735872. Moore C, Woollard M. . Emerg Med J. 2005 Jul;22(7):512-5. doi: 10.1136/emj.2004.020693.

Emergency Medical Minute

Contributor: Jared Scott, MD Educational Pearls: Pathologic bone fractures occur due to weakened bones from chronic disease and with less force when compared to non-pathologic fractures Can be due to bone tumors, bone cysts, infections (osteomyelitis), osteogenesis imperfecta, Paget's disease of bone, and multiple myeloma Have moth bitten or lytic appearance and you can sometimes see the periosteum peeling away from the bone References Angelini A, Trovarelli G, Berizzi A, Pala E, Breda A, Maraldi M, Ruggieri P. Injury. 2018 Nov;49 Suppl 3:S77-S83. doi: 10.1016/j.injury.2018.09.044. PMID:...

Emergency Medical Minute

Contributor: Jared Scott, MD Educational Pearls: Bilirubin is natural breakdown product of red blood cells but can be neurotoxic if levels become too high Fetal red blood cells are fragile and break down easier, leading to higher bilirubin levels in neonates  Immature livers and increased intestinal absorption from sterile bowels also contribute to elevated levels and jaundice in all neonates Other risk factors for neonatal jaundice include: temperature instability, poor feeding, hypoxia at birth, and being of East Asian descent Neonatal bilirubin levels are referenced to time since...

Pharmacy Phriday #7: Bactrim Adverse Events show art Pharmacy Phriday #7: Bactrim Adverse Events

Emergency Medical Minute

Contributor: Cheyenne Bean, PharmD Educational Pearls: Bactrim (TMP-SMX) is a sulfa antibiotic used for a number of infections but can have untoward effects. Hypoglycemia can be induced by the sulfa component of Bactrim, which binds receptors in the pancreas causing insulin to be secreted, dropping blood sugar levels. Oral diabetic medications, specifically sulfonylureas, when taken with Bactrim most often lead to these hypoglycemic episodes. Hyperkalemia can be induced by Trimethoprim by blocking potassium excretion in the kidney, so Bactrim in combination with ACE...

Podcast 631: UK COVID-19 Mutation show art Podcast 631: UK COVID-19 Mutation

Emergency Medical Minute

Contributor: Gretchen Hinson, MD Educational Pearls: Viruses mutate frequently and a new variant of COVID has been found in the United Kingdom. Mutations typically occur due to transcription errors during virus replication leading to slight changes in the virus which can alter its virulence, and this UK mutation has shown more infectivity. The UK variant was first identified on 9/20/20 and sequenced in October The variant has a mutation of the spike protein with increased receptor binding capacity, making it more efficient at infecting cells Children seem to be more susceptible to this...

Podcast 630: Evolution of an STEMI show art Podcast 630: Evolution of an STEMI

Emergency Medical Minute

Contributor: Peter Bakes, MD Educational Pearls: Hyperacute T waves can occur immediately and typical last less than an hour Hyperacute T waves are typically broader than peaked T-waves, which are associated with hyperkalemia ST elevation which usually starts within an hour of the inciting event and can last up to a few days, and often follows the hyperacute T-waves Q waves can begin at the time ST elevation begins and can remain permanently T waves can invert before normalizing again days later References Levis JT. . Perm J. 2015;19(3):79. doi:10.7812/TPP/14-243 Vogel B, Claessen BE,...

Podcast 629: Inferior STEMI show art Podcast 629: Inferior STEMI

Emergency Medical Minute

Contributor: Jared Scott, MD Educational Pearls: EKGs look at different angles, or vectors, of the heart’s electrical conduction as it travels through the heart. Knowing how to read these vectors is essential in diagnosing locations of cardiac pathologies  Leads II, III, and aVF follow an inferior path, so ST elevation in those leads indicates inferior involvement Major complications more common with inferior STEMIs can include:  hypotension which can be made worse by nitroglycerin Severe bradycardia due to SA/AV node involvement Inferior STEMI, barring no hypotension or...

Emergency Medical Minute

Contributor: Peter Bakes, MD Educational Pearls: STEMI criteria is not just 1mm elevation in contiguous leads 1.5 mm in V2-V3 for women 2.0 mm in V2-V3 for men 2.5 mm in V2-V3 for men under 40 Inferior MI typically have ST elevation in leads II, III and aVF Usually inferior MI’s show reciprocal changes (ST depression) in the lateral leads. Lateral MI typically elevation in V5, V6, I, and aVL Anterior MI show elevation in leads V1-4 Right sided MIs have mixed pattern, showing elevation in V1-V2 and V4 along with the inferior leads. Right sided MI’s are very sensitive to nitrates,...

Emergency Medical Minute

Contributor: Aaron Lessen, MD Educational Pearls: High flow nasal cannula (HFNC) has become more utilized with COVID pandemic Multiple studies have shown this method improves both oxygenation and ventilation Newer studies have shown the respiratory benefit of HFNC  vs normal oxygen in patients suffering from CHF and those with do not intubate orders who are experiencing respiratory distress.   Heated high flow is another option to provide ventilator and oxygen support to patients who either do not need or do not want to be intubated References Kang MG, Kim K, Ju S, et al. .
