About

Transcranial motor evoked potential (TcMEP) monitoring is conventionally performed during neurosurgical procedures without or with minimal neuromuscular blockade (NMB) because of its potential interference with signal interpretation. However, full blockade offers increased anesthetic management options and facilitates surgery. Here, investigators want to assess the effect of Sugammadex during TcMEP in adult patients. Sugammadex is designed to encapsulate rocuronium and reverse rocuronium-induced neuromuscular blockade. 64 patients undergoing thoracic or lumbar spinal surgery will be randomly allocated into sugammadex group or control group under a ratio of 1 to 1. Patients will receive either continuous infusion of rocuronium to produce blockade maintained at least two twitches in Train-of-Four (TOF), rocuronium infusion will be discontinued and 2 mg/kg of sugammadex will be infused while dura opening in sugammadex group. Whereas no muscle relaxant will be given after anesthetic induction in control group. The primary aim of this study is to compare mean value of amplitudes of TcMEPs in abductor pollicis brevis muscles of both upper extremities 5 minutes after dura opening.
