Postoperative sore throat
Conditions
Interventions
control group (supine position):When the pressure >40mmH2O is detected, it should be adjusted to 25 ~ 30mmH2O
experimental group 1 (prone position):When the pressure >40mmH2O is detected, it should be adjusted to 25 ~ 30mmH2O
experimental group 2 (prone position):During the operation, the cuff pressure was maintained at 25 ~ 30cmH2O and no leakage was ensured in the endotracheal tube
