Lung Ultrasound Evaluation of the Effects of PEEP and Recruitment Strategies Adjusted for Intraoperative Dynamic Compliance on Postoperative Respiratory Complications in Obese Patients Planned for Laparoscopic Surgery

This study aims to investigate the effects of the personalized application of respiratory pressures applied to patients undergoing laparoscopic bariatric surgery when they are connected to a ventilator under general anesthesia, on the postoperative period. The effects of the ventilation practices that are fixed in routine practice and revised according to various variables during the surgery during artificial respiration after intubation under general anesthesia will be examined with ultrasonography. No change will be made to the routine anesthesia practice for this purpose, the pressure values in the ventilator under general anesthesia will be adjusted during the surgery within the framework of the values used in anesthesia practice. After the surgery, the lung area will be examined with ultrasound in the recovery unit and the findings will be recorded. This study does not have any undesirable effects or risks. This study does not include any interventional procedures.
