Lead Sponsor: The Dean

Brief Summary: The role of ultrasonography in pulmonary imaging has gained importance recently to identify atelectasis. Moreover, the Trendelenburg position used in laparoscopic gynaecologic or colon surgery causes the abdominal contents to push the diaphragm more cephalad, resulting in aggravated lung collapse and decreased functional residual capacity. Intraoperative atelectasis is associated with decreased lung compliance, impaired oxygenation, increased pulmonary vascular resistance, and lung injury. Moreover, atelectasis can persist postoperatively and results in respiratory complications, such as hypoxemia, increased ICU stay, oxygen

supplementation and infection which significantly impacts patient recovery. Hypothesis of this study is perioperative atelectasis grading more in obese patient than overweight patient for laparascopic surgery cases.

This study aims to assess the grading of perioperative atelectasis in patients undergoing elective laparoscopic surgery under general anaesthesia using modified lung ultrasound score (LUS).
