Abstract
STUDY OBJECTIVE: This study aimed to compare the impact of stylet application for tracheal intubation for postoperative pharyngeal pain or hoarseness in patients undergoing elective surgery. DESIGN: Randomized clinical trial. SETTING: Operating room. PATIENTS: Forty adult patients scheduled for elective surgery under tracheal intubation with an ASA physical status of 1-3. INTERVENTIONS:Tracheal intubation was performed by anesthesiologists with stylet group (Stylet group; 20 patients) or without stylet group (Control group; 20 patients). MEASUREMENTS: Incidence of postoperative pharyngeal pain or hoarseness was assessed. MAIN RESULTS: The 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). CONCLUSIONS: Stylet use increases the incidence of postoperative pharyngeal pain.
