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:  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.
