Design outcomes

Primary

Measure	Time frame
Lung ultrasonography score (LUS score) between groups at the end of surgery (just before emergence) as a lower LUS indicates better lung aeration.	—

Secondary

Measure	Time frame
Lung ultrasonography score (LUS score) between groups post induction, post first recruitment and at the PACU.;Heart rate, blood pressure, oxygen saturation, ETCO2, arterial partial pressure of oxygen (PaO2), arterial partial pressure of carbon dioxide (PaCO2), PaO2/FiO2, peak inspiratory pressure and plateau pressure.;PPCs within the first 3 postoperative days (pneumothorax, pleural effusion, pulmonary collapse, atelectasis, pneumonia, acute respiratory distress syndrome (ARDS), or pulmonary aspiration).	—
