Individualized Intraoperative PEEP Following Alveolar Recruitment Maneuvres and Postoperative Respiratory Complications

Patients ASA I-III, undergoing laparoscopic abdominal surgery will be randomly assigned, into one of two groups, namely group C-PEEP , that will be the control group ; and group I-PEEP, where alveolar recruitment maneuvres will take place in order to identify each patient's individualized optimal PEEP. All patients will receive a standardized anesthesia regimen. The lung ultrasound score will be evaluated in all patients in the PACU and then respiratory complications will be recorded on the 24th hour, 48th hour, 7th day and 30the day, postoperatively.
