Eligibility Criteria

Inclusion Criteria

•Adult patients scheduled to undergo elective laparoscopic gynecological surgery (laparoscopic ovarian cystectomy or laparoscopic salpingo-oophorectomy or laparoscopic hysterectomy or laparoscopic myomectomy) under general anesthesia, with ASA physical status classification I or II

Exclusion Criteria

•Previous history of lung surgery
•Patients having pneumonia, pneumothorax, or pleural effusion in preoperative chest X-ray
•Patients with COPD, emphysema
•Patients with previous history of pneumothorax, or bullae
•Morbid cardiac disease
•Adolescent aged \< 18 years
•Anticipated duration of surgery \< 1 hour

Outcomes

Primary Outcomes

modified lung ultrasound score at the end of surgery

Time Frame: At the end of surgery

Both lung ultrasound scores can be calculated by adding up the 12 individual pulmonary quadrant scores yielding a score between 0 (no aeration loss) and 36 (complete aeration loss).

Secondary Outcomes

intraoperative SpO2(intraoperative)
modified lung ultrasound score at post-anesthesia care unit (PACU)(intraoperative)
incidence of atelectasis diagnosed by ultrasonography(intraoperative)
arterial blood gas analyses(intraoperative)
incidence of postoperative complications(during the postoperative period until discharge from hospital, an average of 3 days)
intraoperative mean arterial pressure(intraoperative)
intraoperative peak airway pressure(intraoperative)
Incidence of postoperative shoulder pain at POD #1(assessed at postoperative day 1)
