| Whether atelectasis occurred at the end of the operation in both groups; | — |
Secondary
| Measure | Time frame |
|---|---|
| LUS score at each time point in the two groups of patients;Hemodynamic parameters (HR, MAP, SpO2, arterial blood gas) at each time point;Mechanical ventilation parameters at each time point (maximum airway pressure, mean airway pressure, dynamic pulmonary compliance, PEEP value, number of retractions);Alveolar arterial oxygen partial pressure difference at each time point;respiratory index at each time point;hypotension during atelectasis;Postoperative pulmonary complications;Length of stay in PACU/ICU, postoperative hospital stay.;Baseline characteristics (sex, age, height, weight, comorbidities, history of operation, history of special medication, main diagnosis, intraoperative intake and withdrawal, operation time, anesthesia time, extubation time, smoking history, etc.); | — |
