Rocuronium‐Induced Anaphylaxis in the Perioperative Period: A Clinical Review

Abstract

Rocuronium, a nondepolarizing neuromuscular blocking agent used for muscle relaxation especially during endotracheal intubation, can cause hypersensitivity reactions. This article provides an overview of anaphylactic reactions; risk factors; and the pathophysiology, presentation, diagnosis, treatment, and nursing implications associated with rocuronium‐induced anaphylaxis. Life‐threatening anaphylaxis can be immunoglobulin E–mediated or non–immunoglobulin E‐mediated and usually occurs after the first dose. Anaphylaxis can present with hypotension and bronchospasm; cutaneal symptoms, such as erythema, may not be obvious. Diagnosis is initially presumptive and may require a transesophageal echocardiogram to rule out other causes of hypotension (eg, pulmonary embolus). Emergency treatment begins with epinephrine administration and fluid boluses; cardiac support devices may be needed. Definitive diagnosis requires early measurement of histamine and tryptase levels and skin testing after the patient recovers from the reaction. Perioperative nurses should be prepared to participate in emergency treatment of anaphylaxis and advocate for testing for a definitive diagnosis.
