title: Effects of stylet use during tracheal intubation on postoperative pharyngeal pain in anesthetized patients: A prospective randomized controlled trial.
abstract: 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.
  
  
  METHODS
  Randomized clinical trial.
  
  
  METHODS
  Operating room.
  
  
  METHODS
  Forty adult patients scheduled for elective surgery under tracheal intubation with an ASA physical status of 1-3.
  
  
  METHODS
  Tracheal intubation was performed by anesthesiologists with stylet group (Stylet group; 20 patients) or without stylet group (Control group; 20 patients).
  
  
  METHODS
  Incidence of postoperative pharyngeal pain or hoarseness was assessed.
  
  
  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.
