| Peak pressure, plateau pressure and average airway pressure during mechanical ventilation after endotracheal intubation;Whether there are postoperative pulmonary complications; | — |
Primary
| Measure | Time frame |
|---|---|
| Systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse oxygen saturation and heart rate were recorded 10 minutes after entering the room, after airway surface anesthesia, when placing laryngoscope, and immediately after endotracheal intubation.;Techanivate score was used to evaluate intubation response;Record whether choking, ventilation and pulse oxygen saturation during extubation.;VAS score was used to record the patient's throat at 0, 4, 12 and 24h after extubation.; | — |
