Arms & Interventions
LUS-guided alveolar recruitment
Lung ultrasound-guided alveolar recruitment maneuver will be performed
Intervention: lung ultrasound-guided alveolar recruitment (Procedure)
conventional alveolar recruitment
Alveolar recruitment maneuver will be provided with positive pressure of 30 cmH2O for 10 seconds.
Intervention: conventional alveolar recruitment (Procedure)
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)
