Lung Recruitment Manoeuvre in Morbidly Obese Patients Underdoing Laparoscopic Bariatric Surgery

Lung ultrasonography is an easy-to-use, portable, non-invasive, visual, and non-radiative technique that has been widely used in clinical monitoring and diagnosis. Many studies have demonstrated that pulmonary ultrasonography can evaluate the degree of aeration loss and diagnose atelectasis accurately by using a validated semiquantitative score in the perioperative period, and lung ultrasonic imaging can be conducive to confirming the effects of lung recruitment manoeuvres. This clinical trial suggested that the use of ultrasound-guided recruitment maneuver in morbidly obese patients scheduled for laparoscopic bariatric surgery can improve the lung aeration, decrease the incidence of basal lung atelectasis, decrease the incidence of intraoperative\& postoperative oxygen desaturation, and reduce the incidence of post operative pulmonary complications. The aim of this prospective randomized clinical study is to compare the conventional recruitment manoeuvre and ultrasound-guided recruitment manoeuvre in morbidly obese patients scheduled for laparoscopic bariatric surgery.
