Brief summary (registry, in English)
The aim of this study is to compare the effect of individualized PEEP based on transmural lung pressure and fixed PEEP on postoperative pulmonary complications during laparoscopic or robotic abdominal surgery in obese patients. The main questions are: 1. whether the intraoperative application of individualized PEEP in obese patients can reduce the incidence of postoperative pulmonary complications at 7d, 30d, and 90d postoperatively compared to fixed PEEP 2. Whether the application of individualized PEEP in obese patients can optimize intraoperative respiratory mechanics, oxygenation index (PaO2/FiO2), PaCO2, and EtCO2 compared with fixed PEEP. 3 Whether the application of individualized PEEP in obese patients can reduce the incidence of non-respiratory complications, postoperative QoR-15 scores, unplanned reintubation, unplanned transfers, and unplanned extubation in the postoperative period compared with fixed PEEP. planned reintubation, unplanned transfers to ICU and ICU days, hospitalization days, 30-day and 90-day mortality. Participants will: Patients with BMI \>= 30 kg/m² undergoing laparoscopic or robotic abdominal surgery received PEEP during surgery (divided into individualized PEEP and fixed PEEP), and were followed up for 90 days to observe the incidence of pulmonary complications and related study outcomes.
