Comparison of lung recruitment manoeuvre with Peep (positive end- expiratory pressure) and only peep (positive end -expiratory pressure) on development of Atelectasis in patients undergoing laparoscopic Surgery - a randomized control trial

Abstract

ABSTRACT Title of the article: Comparison of Lung Recruitment Manoeuvre with PEEP (Positive End-Expiratory Pressure) and Only PEEP on Development of Atelectasis in Patients Undergoing Laparoscopic Surgery – A Randomized Control Trial Context: Pulmonary atelectasis is a common consequence of general anaesthesia, particularly in elective laparoscopic surgery due to pneumoperitoneum and Trendelenburg positioning. Atelectasis can impair oxygenation, reduce lung compliance, and contribute to postoperative pulmonary complications. Lung-protective ventilation strategies incorporating positive end-expiratory pressure (PEEP) and lung recruitment manoeuvres (LRMs) have been proposed to mitigate these effects. However, the optimal intraoperative strategy remains a subject of debate. Aims: This study aims to compare the incidence of atelectasis in patients undergoing elective laparoscopic surgery under general anaesthesia, receiving either lung recruitment manoeuvre with PEEP (RM Group) or PEEP alone (Control Group). The study further evaluates changes in lung ultrasound scores (LUS) and the impact on perioperative lung function.
