Acute Decompensated Heart Failure and Cardiogenic Shock Following Propofol Infusion: A Report and Review of...

Propofol is a widely used general anesthetic agent with a generally familiar and predictable adverse effect profile. Severe left ventricular dysfunction to an ejection fraction of < 35% is a rare adverse effect of propofol, with a scarcity of data in the literature. In this case, we report a 36-year-old female at 36 weeks gestation with a prior remote history of peripartum cardiomyopathy, who, while receiving propofol for general anesthesia during a C-section, developed severe left ventricular dysfunction with an ejection fraction of 20-25%, flash pulmonary edema, and cardiogenic shock. She required initiation of inotropic support and, following weaning of propofol, gradually recovered her ejection fraction over the next 24 hours to 40-45% and to 50-55% at follow-up two weeks after discharge. This case highlights a unique adverse effect of propofol with scarce pre-existing literature and no guidelines on appropriate management. It is essential for clinicians to be familiar with this uncommon complication, particularly as propofol use continues to rise worldwide.
