Recurrent Laryngeal Nerve Monitoring and Rocuronium: A Selective Sugammadex Reversal Protocol.

Abstract

The use of neuromuscular blocking agents may affect intraoperative neuromonitoring during thyroid surgery. A selective neuromuscular recovery protocol was evaluated in a retrospective cohort study during human thyroid neural monitoring surgery. One hundred and twenty-five consecutive patients undergoing thyroidectomy with intraoperative neuromonitoring followed a selective neuromuscular block recovery protocol-single intubating dose of rocuronium followed by sugammadex if needed at the first vagal stimulation (V1). Data from 120 of 125 patients could be analysed. Fifteen (12.5%) patients needed sugammadex reversal to obtain an EMG response at the first vagal stimulation (V1). In the remaining 105 patients, spontaneous recovery of rocuronium-induced neuromuscular block was sufficient for a successful first vagal stimulation (V1). In patients undergoing thyroid surgery, routine reversal of rocuronium block with sugammadex is not mandatory for reliable intraoperative neuromonitoring. A selective neuromuscular block recovery approach may be a valuable and more cost-efficient alternative to routine reversal.
