Background: We investigated the effect of prolonged inspiratory to expiratory (I/E) ratio ventilation on respiratory mechanics, gas exchange, and regional cerebral oxygen saturation (rSO2) in obese patients undergoing laparoscopic bariatric surgery in the reverse Trendelenburg position.
Methods: Twenty-eight adult patients scheduled for laparoscopic sleeve gastrectomy were enrolled in this prospective observational study. After anesthesia induction, pressure-controlled ventilation was conducted initially at a conventional I/E ratio of 1:2 and a positive end-expiratory pressure of 5 cmH2O.
