effect of use of endotracheal tube with subglottic suction in rhinoplasty

Conditions: Rhinoplasty

Summary: suction above cuff endotracheal tube (sacett) has a dorsal port above the cuff designed to allow continuous or intermittent suctioning of secretions from the subglottic space. thus, it facilitates suctioning of excessive secretions around the mouth and the cuff. in this study, we aimed to investigate the effect of the use of sacett on laryngospasm and postoperative complications in rhinoplasty operations. this randomized controlled clinical trial was conducted in 132 patients undergoing rhinoplasty. the investigators believe that the use of sacett in rhinoplasty operations reduces the incidences of laryngospasm, emergence agitation, sore throat, swallowing difficulty, and ponv when compared with classic endotracheal tube.
