Comparison of I-gel with Baska Mask Airway for Controlled Ventilation in Obese Patients Undergoing Ambulatory Surgery: A Prospective Randomized Trial

The ideal supraglottic airway device must have high airway seal pressures during spontaneous and positive pressure ventilation also low resistance to the flow of gases. This study compared the utility of I-Gel with Baska Mask during general anesthesia in obese patients undergoing elective ambulatory surgeries. The study was conducted on sixty obese patients with body mass index (BMI) of ≥ 25 and ≤ 40 kg.m 2, ASA I, II, III, 18-60 years old of either sex scheduled for short duration (<3 hr). I-gel was successfully inserted in 25 patients on the first attempt and in 2 patients on the second attempt (overall success rate = 90%). Baska mask was successfully inserted in 27 patients on the first attempt and in 2 patients on the second attempt (overall success rate = 96.97%). Successful insertion time was significantly shorter in the I-gel group. Oropharyngeal sealing pressure (OSP) was significantly higher following Baska mask insertion. Intra- and postoperative airway morbidity rates were not significantly different between both groups. So Concluded that both I-gel and Baska mask are suitable for ventilation in obese patients, but Baska mask gave a better laryngeal seal.
