研究组 & 干预措施
LUS-guided alveolar recruitment
Lung ultrasound-guided alveolar recruitment maneuver will be performed
干预措施: lung ultrasound-guided alveolar recruitment (Procedure)
conventional alveolar recruitment
Alveolar recruitment maneuver will be provided with positive pressure of 30 cmH2O for 10 seconds.
干预措施: conventional alveolar recruitment (Procedure)
结局指标
主要结局
modified lung ultrasound score at the end of surgery
时间窗: 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).
次要结局
- 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)
