| Label | Type | Description | Intervention Names |
|---|---|---|---|
| LUS-guided alveolar recruitment | Experimental | Lung ultrasound-guided alveolar recruitment maneuver will be performed |
|
| conventional alveolar recruitment | Active Comparator | Alveolar recruitment maneuver will be provided with positive pressure of 30 cmH2O for 10 seconds. |
|
| Name | Type | Description | Arm Group Labels | Other Names |
|---|---|---|---|---|
| lung ultrasound-guided alveolar recruitment | Procedure | Alveolar recruitment maneuver will be performed under lung ultrasound-guidance. Positive pressure will be not exceed 40cmH2O and duration of positive pressure inflation will not exceed 10 seconds. |
| Measure | Description | Time Frame |
|---|---|---|
| modified lung ultrasound score 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). | At the end of surgery |
| Measure | Description | Time Frame |
|---|---|---|
| modified lung ultrasound score at post-anesthesia care unit (PACU) | 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). | intraoperative |
| incidence of atelectasis diagnosed by ultrasonography |
