To determine if desflurane results in a faster emergence as measured by time to eye opening compared to sevoflurane in morbidly obese patients undergoing laparoscopic gastroplasty.

Prospective, randomized, double-blinded study.

Tertiary care hospital.

70 patients with a body mass index of 35 or higher undergoing laparoscopic gastroplasty.

Patients were randomized into two groups to receive either desflurane or sevoflurane for maintenance of general anesthesia.

Intraoperative measured variables included the time from when the inhalation agent was turned off (no agent delivered) to eye opening and the time from when the inhalation agent was turned off to extubation.
