Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Modified lung ultrasound score | 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. | Intraoperative (at the end of operation, before emergence) | |
Secondary | Modified lung ultrasound score | 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. | Postoperative 30 minutes | |
Secondary | Intraoperative desaturation | Oxygen saturation by pulse oximetry <95% | Intraoperative | |
Secondary | Intraoperative partial pressure of arterial oxygen/fraction of inspired oxygen ratio | Partial pressure of arterial oxygen/fraction of inspired oxygen ratio | Intraoperative (20minutes after each recruitment) | |
Secondary | Postoperative partial pressure of arterial oxygen/fraction of inspired oxygen ratio | Partial pressure of arterial oxygen/fraction of inspired oxygen ratio | Postoperative 30 minutes | |
Secondary | Postoperative pulmonary complication | respiratory infection, respiratory failure, pleural effusion, atelectasis, pneumothorax, atelectasis, bronchospasm, aspiration pneumonitis | Postoperative 24 hours |
