Rocuronium Reversal in the Emergency Department: Retrospective Evaluation of Hemodynamic Instability Following Administration of Sugammadex Versus Neostigmine With Glycopyrrolate.

Rocuronium is an intermediate-acting non-depolarizing neuromuscular blocking agent frequently used in the emergency department for rapid sequence intubation. The prolonged effects of rocuronium may prevent the ability to conduct a meaningful neurological examination, thereby delaying appropriate diagnosis and treatment. Sugammadex and neostigmine are pharmacologic agents commonly used to reverse rocuronium. The safety of sugammadex versus neostigmine with glycopyrrolate for the reversal of rocuronium in the emergency department has not been well described. Evaluate the occurrence of hemodynamic instability post-administration of sugammadex versus neostigmine with glycopyrrolate in the emergency department for the reversal of rocuronium. A retrospective cohort study conducted among adult patients that received sugammadex or neostigmine with glycopyrrolate in the emergency department for the reversal of rocuronium. The primary outcome was occurrence of hemodynamic instability that required escalation of treatment. Secondary outcomes included occurrence of hypotensive, bradycardic, or cardiac arrest events. A total of 37 patients met inclusion criteria (n = 10, sugammadex; n = 27, neostigmine). There was no difference between the two groups in regard to hemodynamic instability that required escalation of treatment within 30 minutes after receiving either sugammadex or neostigmine with glycopyrrolate ( = .557). There was no difference between the two groups in regard to occurrence of hemodynamic instability that required escalation of treatment. Given the small sample size, future studies are warranted to further delineate the safety of sugammadex and neostigmine with glycopyrrolate for the reversal of rocuronium in the emergency department.
