Effect of low-dose volatile anesthetics on intraoperative neurophysiological monitoring during anesthesia with remimazolam.

ABSTRACT:

Background

Remimazolam is a novel short-acting benzodiazepine. We investigated the effects of low doses of volatile anesthetic agents on motor evoked potentials (MEPs) and somatosensory evoked potentials (SSEPs) during remimazolam-remifentanil anesthesia.

Methods

Thirty-nine patients undergoing cervical spine surgery were randomly assigned to either the sevoflurane (n = 20) or desflurane (n = 19) groups. Volatile anesthetic agents were administered at 0.3, 0.6, and 0.8 minimum alveolar concentrations (MACs) during remimazolam-remifentanil anesthesia. Significant changes were considered as more than 50% amplitude suppression and more than 10% latency increase from baseline values. The primary outcome was MEP amplitude change. Secondary outcomes included MEP latency, SSEP ampl
