Monitoring of Sugammadex Dosing at a Large Tertiary Care Pediatric Hospital

Abstract

Introduction: Anesthesiologists use sugammadex to reverse neuromuscular blockade (NMB) produced by rocuronium and vecuronium. Its mechanism involves encapsulation of the neuromuscular blocking agent. Sugammadex dosing is based on the depth of NMB, assessed by measuring the train-of-four (TOF).

Methods: We retrospectively reviewed procedures under general anesthesia in patients older than 1 year of age if they included sugammadex reversal of rocuronium-induced NMB. Documentation of TOF monitoring before and after reversal was noted, along with the dose of sugammadex administered. TOF was considered correctly documented if the anesthesia provider recorded the number of twitches before and after NMB reversal, or if they recorded 4 twitches before NMB reversal. We defined appropriate sugammadex dosing if it was within 10% of the recommended dose for the depth of NMB. We repeated this review after staff education and creating a reminder in the electronic health record system.

Results: We included 100 patients in the preintervention analysis, of whom 30% had correct TOF documentation. Among patients with TOF assessment before sugammadex administration, the dose was appropriate in 34 of 40 cases. In the postintervention analysis, we reviewed 75 cases and found that correct documentation improved to 45% (P = 0.024). Among postintervention cases with TOF documented before sugammadex administration, sugammadex dosing was appropriate in 62 patients.

Conclusion: Documentation of TOF was low (30%) before intervention and improved to only 45% after the interventions, suggesting that additional interventions are needed. Even before the intervention, with or without TOF documentation, the dose of sugammadex was generally consistent with recommendations.
