Sixty four participants were assigned to one of the two groups: cylindrical and TaperGuard endotracheal tube. At the supine position, cuff pressure of endotracheal tube was measured before and after abdominal insufflation in the supine position. After insufflation the head-up position (30°) was made and cuff pressure was recorded.
The purpose of this study was to compare the cuff pressure between cylindrical and TaperGuard endotracheal tube during laparoscopic cholecystectomy.
