Driving Pressure-guided Positive End-expiratory Pressure to Prevent Postoperative Atelectasis in Obese Children: a Prospective, Randomized Controlled Clinical Trial

At present, the use of lung protective ventilation strategies in children is mainly based on adult and intensive care unit data. Although obese children may benefit more from lung protective ventilation, there are few studies on the use of lung protective ventilation strategies in obese children during surgery. Therefore, the investigators hypothesized that intraoperative use of LPV strategies in obese pediatric surgery patients can reduce atelectasis and improve the incidence of postoperative pulmonary complications.
