Postoperative Analgesic Requirements for the ProSeal Laryngeal Mask Airway Versus the Tracheal Tube in Females Undergoing Gynecological Laparoscopic Surgery

Postoperative Analgesic Requirements for the ProSeal Laryngeal Mask Airway Versus the Tracheal Tube in Females Undergoing Gynecological Laparoscopic Surgery

The ProSeal laryngeal mask airway is a relatively new airway device with a modified cuff to increase the seal and a drain tube to provide a channel for regurgitated fluid, prevention of gastric insufflation and insertion of a gastric tube. In the following randomized prospective double-blind trial, we test the hypothesis that the postoperative analgesic requirements is higher for the ProSeal laryngeal mask airway than the tracheal tube.
