Atelectasis
Conditions
Interventions
Experimental group :At 5 minutes (T1) and the end of surgery (T2), bilateral lung ultrasound evaluation was first performed to determine the scoring area
Pressure control method of lung compression in the selected area according to the score: adjust airway pressure from 10 cmH2O, add 5 cmH2O each time, with a maximum of 30 cmH 2 O for 30 seconds, and o
Control group:Under the premise of airway pressure maintenance, the anesthesia machine was adjusted to manual mode for manual ventilation, and the pressure was maintained at 30 cmH2O for 30 seconds.
