Purpose Of ReviewThis review describes recent prospective and retrospective work exploring the incidence and clinical consequence of sugammadex-induced bradycardia and an update of recent evidence and adverse event reports to the United States Food and Drug Administration regarding the incidence of sugammadex induced bradycardia.Recent FindingsThis work suggests that the incidence of sugammadex-induced bradycardia can range from 1 to 7% depending on the definition to reverse moderate to deep neuromuscular blockade. For most instances, the bradycardia is inconsequential. For those instances that have hemodynamic instability, the adverse physiology is easily treated with appropriate vasoactive agents. One study demonstrated that the incidence of bradycardia from sugammadex is less than with neostigmine. There are several case reports that describe marked bradycardia with cardiac arrest from reversal with sugammadex. The incidence of this type of reaction to sugammadex appears to be very rare. Data from the United States Food and Drug Administration's Adverse Event Reporting System public dashboard corroborates this presence of this rare finding.SummarySugammadex-induced bradycardia is common and, in most instances, of minimal clinical consequence. Nevertheless, anesthesia providers should maintain proper monitoring and vigilance to treat hemodynamical instability with each administration of sugammadex.Copyright © 2023 Wolters Kluwer Health, Inc.
