Does Lung Compliance Optimization Through PEEP Manipulations Reduce the Incidence of Postoperative Hypoxemia in Laparoscopic Bariatric Surgery? A Randomized Trial.

Abstract

In obese patients (OP), the best intraoperative ventilation strategy remains to be defined. Dynamic lung compliance (Cdyn) and dead space fraction are indicators of efficient ventilation at an optimal positive end-expiratory pressure (PEEP). Herein, we investigated whether intraoperative dynamic lung compliance optimization through PEEP manipulations affects the incidence of postoperative hypoxemia (SpO2 < 90%) in OP undergoing laparoscopic bariatric surgery (LBS).
