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.

|---|---|---|
| Difference in oxygen concentration in the oropharynx between cuffed and uncuffed ETT. | 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. | 4-5 minutes after induction |
