Lung Ultrasound Versus Dynamic Lung Compliance to Detect the Optimum Positive End-Expiratory Pressure After Alveolar Recruitment for Patients Undergoing Laparoscopic Gastric Sleeve Surgery: A Randomized Trial

Abstract

Background: Various maneuvers are used to maintain oxygenation and prevent atelectasis and desaturation during general anesthesia in bariatric surgery. These maneuvers include alveolar recruitment (ARM) and positive end-expiratory pressure (PEEP). The current study aimed to illustrate the role of transthoracic lung ultrasound (LUS) as a clinical tool in comparison to dynamic lung compliance Cdyn for the detection of optimum PEEP after ARM for obese patients undergoing laparoscopic gastric sleeve surgery.
