Evaluation of Sugammadex Dosing for Neurological Examination in the Emergency Department.

Background: Prolong effects of non-depolarizing neuromuscular blocking agents after rapid sequence intubation may prevent meaningful neurological examination, delaying appropriate diagnosis and neurosurgical intervention. Sugammadex is indicated for the reversal of neuromuscular blockade induced by rocuronium. Objective: The objective of this study was to evaluate low- (2 mg/kg) vs standard-dose (4 mg/kg) sugammadex for rocuronium-induced deep neuromuscular blockade reversal in the emergency department (ED) by achieving a post-treatment train-of-four (TOF) of 4 to facilitate neurological examination. Methods: This was a single-center, retrospective, cohort study evaluating low-vs standard-dose sugammadex for neuromuscular blockade reversal in the ED. Results: 34 patients were identified within the designated time period, 24 of which were included in the final analysis ([n = 9 low-dose], [n = 15 standard-dose]). Median sugammadex doses were 2.3 mg/kg and 4.1 mg/kg for low- and standard-dose, respectively. The majority of patients presented for intraparenchymal hemorrhage (54.2%). No significant difference in success rate of NMBA reversal was found between low- and standard-dose sugammadex ([100.0% vs 93.3%], P = 1.000). A total of 9 patients had a neurosurgical procedure performed after sugammadex administration. Low-dose sugammadex was associated with significantly less acquisition cost compared to the standard dose (P <.001). Conclusion: Low- (2 mg/kg) and standard-dose (4 mg/kg) sugammadex successfully reversed rocuronium-induced deep neuromuscular blockade in the ED by achieving a post-treatment TOF of 4 to facilitate neurologic examination. Low-dose sugammadex may be a viable option for deep NMBA reversal in the ED and is associated with decreased institutional cost. [ABSTRACT FROM AUTHOR]
