Summary

Major laparoscopic sleeve gastrectomy surgery requires steep Trendelenburg position with pneumoperitoneum for a long time leading to decrease pulmonary compliance and lung volumes due to cephalic displacement and decrease excursion of the diaphragm, consequently leading to the possibility of atelectasis formation. Different strategies have been proposed to reduce atelectasis and other pulmonary complications in obese patients as induction of anesthesia in the head up position with or without CPAP, protective intraoperative mechanical ventilation with high or low levels of PEEP and implementation of Recruitment Maneuvers. Up to investigators' knowledge, there is no study done to evaluate the effect of intraoperative use of PEEP and alveolar recruitment maneuver on diaphragmatic function and incidence of atelectasis via ultrasonography in obese patients undergoing laparoscopic sleeve gastrectomy.
