Study type | Interventional |
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.

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | changes of Diaphragmatic excursion (DD) | will be measured by low frequency probe of Sonosite M Turbo ultrasonography, measurements will be taken before induction of anaesthesia, 5 min after completion of pneumoperitoneum, 5 min after adopting Trendelenburg position, 60 min later with pneumoperitoneum and Trendelenburg position, 5 min after exsufflation of pneumoperitoneum and patient placed back in the supine position, 15 min after arrival of patient in the recovery room and 24h postoperatively. | 24 hour postoperative | |
Secondary | Incidence of lung atelectasis | atelectasis will be assessed by a linear probe of Sonosite M Turbo ultrasonography. Its measurements will be taken just before induction of anaesthesia, 15 min after arrival of the patient in the recovery room and 24h postoperatively. | 24 hour postoperative |
