Study ObjectiveThis study aimed to compare the impact of stylet application for tracheal intubation for postoperative pharyngeal pain or hoarseness in patients undergoing elective surgery.DesignRandomized clinical trial.SettingOperating room.PatientsForty adult patients scheduled for elective surgery under tracheal intubation with an ASA physical status of 1-3.InterventionsTracheal intubation was performed by anesthesiologists with stylet group (Stylet group; 20 patients) or without stylet group (Control group; 20 patients).MeasurementsIncidence of postoperative pharyngeal pain or hoarseness was assessed.Main ResultsThe incidence of postoperative pharyngeal pain was significantly higher in the Stylet group (10/20 patients) than in the Control group (2/20 patients) (P=0.013). The incidence of hoarseness did not significantly differ between the Stylet group (6/20 patients) and the Control group (3/20 patients) (P=0.45).ConclusionsStylet use increases the incidence of postoperative pharyngeal pain.Copyright © 2017 Elsevier Inc.
