About this study
Official title: Effect of Different Positions During Extubation on Incidence of Hypoxemia in the Peri Extubation Period of Pediatric OSAS Surgery Under General Anesthesia, Randomized Controlled Trial
Pediatric Obstructive Sleep Apnea Syndrome (OSAS) is common, often due to enlarged tonsils/adenoids. Tonsillectomy/adenoidectomy frequently performed under GA with tracheal intubation due to the age of children. Risk of hypoxemia and respiratory complications during the peri-extubation period is high.
Read the detailed description
The most common disorder of sleep apnea in children is obstructive sleep apnea syndrome (OSAS), characterized by interrupted breathing and partial or complete obstruction of the upper airway, the main factor is the enlargement of the tonsils and adenoids in the pediatric pharynx. The clinical symptoms are snoring, and open-mouth breathing, then resulting in hypoventilation and hypoxemia. Due to the age of children, tonsillectomy and adenoidectomy are often performed under general anesthesia with tracheal intubation. The risk of hypoxemia and the degree of oxygen saturation reduction are bigger when the mask was removed in the supine position, and the most serious complication also occurred in the supine position. Therefore, the lateral position is preferable to the supine position for mask removal. 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. In this study, we will investigate and compare whether the use of lateral position or semi-prone position impact on the occurrence of choking, agitation, decreased pulse oxygen saturation - (SpO2) and the oral and nasal secretions during the awakening period.

| Study group | Role | What they receive |
|---|---|---|
| Group L (lateral position): | Active comparator | ENT surgery patients positioned laterally with head in zero position after completion of surgery and before extubation till full recovery and discharge from PACU. Receives: Procedure: positioning during peri-extubation |
| Group S (Sim' position): | Active comparator | ENT surgery patients positioned in semi-prone position after completion of surgery and before extubation till full recovery and discharge from PACU. Receives: Procedure: positioning during peri-extubation |
What is being measured
The primary outcome is the main question the study is designed to answer.
Incidence of hypoxemic events in the peri-extubation period
Hypoxemic events which last > 2 seconds after extubation will be recorded when Spo2 is less than 94% on room air.
Measured: one hour after extubation
Secondary outcomes (1)
Incidence of respiratory complications
Incidence of respiratory complications such as choking, laryngospasm, posterior tongue drop.
Measured: one hour after extubation
