Impact of Using a Cuffed Endotracheal Tube on Limiting the Risk of Airway Fire

This study has been completed.

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.

Condition Intervention
Adenoidectomy Tonsillectomy Adenotonsillectomy Other: Cuffed ETT Other: Uncuffed ETT

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic

Further study details as provided by Joseph D. Tobias, Nationwide Children's Hospital:

Primary Outcome Measures:
  • Difference in oxygen concentration in the oropharynx between cuffed and uncuffed ETT. [ Time Frame: 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.
