Abstract

Purpose: An electromyographic (EMG) tube is sometimes used for vagal nerve monitoring during neurosurgery. Some characteristics of an EMG tube are different from those of a normal endotracheal tube. Although postoperative laryngeal edema (PLE) may occur and reintubation may be required in some patients in whom an EMG tube is used, its relevance to these events has not been investigated in detail. Our goal was to determine the relevance of an EMG tube to the development of PLE and the need for reintubation. Methods: A retrospective study was conducted in 900 patients after neurosurgery from 2012 to 2018. Severe PLE occurrence or the requirement for postoperative reintubation were compared between the EMG tube (E) group and the Normal tube (N) group, using a propensity score (PS) matching analysis Results: After PS matching, severe PLE incidence (n = 2/20, 10.0%) in the E group was significantly higher than that (0/80, 0%) in the N group. There was no significant difference in the incidence of reintubation between the E group (1/20, 5.0%) and the N group (0/80, 0%). Conclusion: Electromyographic (EMG) tube use was significantly associated with higher incidence of severe PLE.
