Background: Laparoscopic surgery with reverse Trendelenburg position and carbon dioxide pneumoperitoneum has been known to increase the endotracheal tube (ETT) cuff pressure and the incidence of postoperative sore throat. The purpose of this study was to evaluate the effect of the Trendelenburg position and pneumoperitoneum on the ETT cuff pressure and the effect of adjustment of ETT cuff pressure on the incidence of sore throat during laparoscopic gynecologic surgery.
Methods: One hundred fifty-four female patients undergoing laparoscopic gynecologic surgery were randomly assigned to either control group or adjusted group. In control group, initial cuff pressure was set at 30 cmH2O in the supine position without any adjustment during surgery. Cuff pressure of adjusted group was adjusted to maintain 30 cmH2O throughout the operation. Cuff pressures at intubation (Pimme), at carbon dioxide insufflation and the Trendelenburg position (P0), and at 10 minute intervals throughout surgery (P10−P60 and Pend) were checked. Postoperative airway complications including sore throat, hoarseness, dysphagia and cough were compared between the two groups at 2 hours and 24 hours after surgery.
Results: In control group, P0 and P10 were significantly higher than Pimme. The cuff pressure decreased with time, thereby; P50 (28.2± 4.3), P60 (27.5 ± 4.0) and Pend (25.9 ± 4.2) were significantly lower than Pimme (P ＜ 0.05). The incidences and severity of airway complications were not different between two groups.
Conclusions: ETT cuff pressure decreased in laparoscopic gynecologic surgery. Therefore, controlled cuff pressure does not decrease the incidence of postoperative airway complications.
