Authors' conclusion

Driving pressure-guided PEEP did not decrease the incidence of pulmonary complications within 7 days of laparoscopic or robotic lower abdominal surgery, although uncertainty remains given the lower than anticipated event rate for the primary outcome.

Study context

Population
Patients at risk for postoperative pulmonary complications (PPCs) undergoing laparoscopic or robotic lower abdominal surgeryrandomised
