Minimal Occlusive Pressure With Cuffed ETT: the Effect of Size on Intracuff Pressure

Not Applicable

Completed

• Conditions: ETT Size; Intracuff Pressure

• Registration Number: NCT02376101
• Lead Sponsor: Senthil G. Krishna

Brief Summary

The purpose of this current study is to evaluate whether the size of the endotracheal tube (ETT) that is used impacts the intracuff pressure that occurs when the airway is sealed. If there is excessive pressure in the cuff of a smaller ETT when it is inflated, there may be inherent risks associated with the use of a cuffed endotracheal tube that is less than the appropriate size. The investigators believe that the size of the tube chosen has an impact on the characteristics of the inflated cuff and hence the intracuff pressure and the sealing pressure are variable.

Primary Outcome Measures

Name	Time	Method
Intracuff pressure	intraoperative	Our goal is to measure the intracuff pressure that is achieved when the airway is sealed with an ETT based on the formula (ETT=(age/4)+3) and compare it to the intracuff pressure when the airway is sealed with an ETT that is 1 size smaller (4.0 mm instead of 5.0 mm).
