研究概览
简要总结
The purpose of this study is to evaluate the impact of using a cuffed endotracheal tube (ETT) on the oxygen concentration in the oropharynx during adenoidectomy, tonsillectomy, or adenotonsillectomy. The study hypothesis is that inflation of the cuff on the ETT will eliminate contamination of the oropharynx with the inspired anesthetic gases and decrease the oxygen concentration in the oropharynx.

结局指标
主要结局
Difference in oxygen concentration in the oropharynx between cuffed and uncuffed ETT.
时间窗: 4-5 minutes after induction
The oxygen and sevoflurane (anesthetic agent) concentration of the oropharynx would be measured during positive pressure ventilation immediately after intubation and then 4-5 mins. after anesthetic induction when the patient resumes spontaneous ventilation.
