Contributor: Dylan Luyten, MD Educational Pearls: After you diagnose a pulmonary embolism (PE) via CT or VQ scan, we need to categorize the PE as massive, sub-massive, or just PE to dictate treatment. Massive PE: shock with hypotension due to an embolism, and the treatment of choice is thrombolysis with IV tPA with anticoagulation after lysis. Catheter thrombolysis is not used in the hemodynamically unstable patient but can be done after they are stable. Sub-massive: signs of right heart strain/...

Contributor: Sam Killian, MD Educational Pearls: Agitation can be due to a number of causes, but regardless of the cause, sedation often plays a key role in patient and provider safety. But what is the best sedative agent? A study looked at control of agitation with intramuscular medication. Specifically, 5 different IM sedative agents were compared to see which one best provides “adequate” sedation in 15 minutes or less. Haldol 5mg, Haldol 10mg, Versed 5mg, Zyprexa 10mg, and Geodon 20mg were al...

Author: Aaron Lessen, MD Educational Pearls: Previously, trials had shown promising evidence that vitamin C may improve mortality rates in patients with sepsis or septic shock. A 2017 retrospective before-after study gave a “cocktail” of hydrocortisone, vitamin C, and thiamine to patients with severe sepsis or in septic shock and reported a decrease in mortality from 40% to 8%. A 2020 randomized controlled trial demonstrated that giving patients hydrocortisone, vitamin C, and thiamine showed no ...
