研究组 & 干预措施
FiO2_1.0
Alveolar recruitment is performed with 100% oxygen concentration at specific time points.
干预措施: FiO2_1.0 (Procedure)
FiO2_0.4
Alveolar recruitment is performed with 40% oxygen concentration at specific time points.
干预措施: FiO2_0.4 (Procedure)
结局指标
主要结局
Modified lung ultrasound score
时间窗: Intraoperative (at the end of operation, before emergence)
The score is calculated by adding up the 12 individual quadrant scores assessed using lung ultrasound. Each quadrant score ranges from 0 (minimal atelectasis)\~3 (severe atelectasis), so the maximum total score is 36.
次要结局
- Modified lung ultrasound score(Postoperative 30 minutes)
- Intraoperative desaturation(Intraoperative)
- Intraoperative partial pressure of arterial oxygen/fraction of inspired oxygen ratio(Intraoperative (20minutes after each recruitment))
- Postoperative partial pressure of arterial oxygen/fraction of inspired oxygen ratio(Postoperative 30 minutes)
- Postoperative pulmonary complication(Postoperative 24 hours)
