The Safety and Efficacy of Push Dose Vasopressors in Critically Ill Adults

REBEL EM

1-4 The PDPs, phenylephrine and epinephrine, result in vasoconstriction and increased cardiac contractility. They can be associated with side effects such as reflex bradycardia, decreased stroke volume in phenylephrine, tachycardia and hypertension associated with epinephrine.

Updates in High dose Insulin and Euglycemia Therapy (HIET) for the treatment of Beta-adrenergic Receptor and Calcium Channel Antagonists Overdose

Core EM

HIET improves contractility without increasing SVR, while vasopressin and epinephrine transiently increase SVR/MAP but worsen cardiac output in anesthetized dogs given propranolol (Holger 2007). Disposition to ICU. Insulin versus vasopressin and epinephrine to treat β-blocker toxicity. J Med Toxicol. 2020;16(2):212-221.

Episode 54: The critically ill patient with pulmonary hypertension, with Ray Foley

Critical Care Scenarios

Signs of baseline and/or new RV strain, such as reduced TAPSE, septal bowing, etc, as well as pericardial effusion, suggest a poor reserve for the stresses of their new ICU course. Epinephrine at lower doses is a good second line, providing inotropic support for the RV without much impact on PVR. Click here to claim your CME credit!

Episode 20: Post-CABG emergencies with Kris Ramilo and Brendan Riordan

Critical Care Scenarios

Looking at the workflow of a fresh post-op open heart surgery patient, as well as what to do when it devolves into cardiac tamponade, with (returning) guest Brendan Riordan, cardiothoracic ICU PA (@concernecus) at the University of Washington, and his NP colleague Kris Ramilo (@krsrml0). Audio quality was a bit dodgy in this one; sorry all!–eds.]
