COMPLICATIONS, OBSTRUCTIVE SLEEP APNEA SYNDROME
The most common disorder of sleep apnea in children is obstructive sleep apnea syndrome (OSAS) [It is accustomed to perform tracheal extubation with the supine position during the awakening period of general anesthesia in children, which may be related to the familiarity of doctors and nurses with the supine operation. However, compared with the supine position, extubation in the lateral position can improve the patency of the airway in children after tonsillectomy and adenoidectomy [There are few reports on the effect of different positions on complications related to tracheal extubation after tonsillectomy and adenoidectomy under general anesthesia in children with OSAS. Previous studies have demonstrated that lateral position or head-high position can improve airway patency in children after tonsillectomy and adenoidectomy, but there is no detailed report on whether the head-high lateral position is a better position for extubation after tonsillectomy and adenoidectomy and the appropriate height of head-high position is not clear and definite. In this study, we proposed to use different height of head-high lateral position to observe and compare the occurrence of choking, agitation, decreased pulse oxygen saturation (SpO
