A Neural Integrity Monitor Electromyography Endotracheal Tube Causes More Severe Postoperative Sore Throat Than a Standard Endotracheal Tube in Adults: A Prospective Cohort Study

Abstract

Background This study aimed at figuring out the different effects of a neural integrity monitor electromyography endotracheal tube (NIM-EMG-ETT) and a standard endotracheal tube (ETT) on postoperative sore throat (POST). Methods This prospective cohort study enrolled 143 patients scheduled to undergo general anesthesia with endotracheal intubation. Patients were allocated into three groups: Group A, non-thyroid surgery with a standard ETT; Group B, thyroid surgery with a standard ETT; Group C, thyroid surgery with a NIM-EMG-ETT. The incidence, the severity and visual analog scale (VAS) of POST were recorded. The incidence and the severity of POST were tested by v 2 test or Fisher's exact test. And VAS of POST was tested by Kruskal-Wallis test. ResultsThe incidences of POST in Group B and Group C were significantly higher than that of Group A at all the time points after extubation (P \ 0.001). The incidences of POST in Group C was significantly higher than that in

“…We read with great interest the recent article by Liu et al [1] comparing the influences of different endotracheal tubes on the occurrence of postoperative sore throat (POST) by a prospective cohort study in patients undergoing thyroidectomy. They showed that a neural integrity monitor electromyography endotracheal tube (NIM-EMG-ETT) resulted in a higher incidence of POST and a worse severity of POST than a standard endotracheal tube.…”
