ObjectiveThis institutional anaesthetic practice evaluation compared patient safety with respect to residual neuromuscular blockade (NMB) at the time of tracheal extubation in patients undergoing high-risk eye surgery.MethodsTwo muscle relaxation regimens were compared: rocuronium administered via intravenous (i.v.) bolus dosing combined with reversal through sugammadex at end of surgery (group R/S; 17 patients); mivacurium administered via continuous i.v. infusion without antagonization (group M; 22 patients). Train-of-four (TOF) monitoring determined the depth of NMB.ResultsThe TOF ratio at the time of tracheal extubation was greater in group R/S (median 1.03) than in group M (median 0.62). Time from end of surgery to tracheal extubation was not significantly different. The surgeons were 100% satisfied with the working conditions provided under both relaxation regimens.ConclusionsResidual postoperative curarization at the time of extubation was frequently observed in group M, whereas there was complete recovery in group R/S. Reversal of NMB by sugammadex provides an additional safety dimension to patient care and should thus be considered especially for those at risk of airway complications or aspiration, in addition to frail patients.
