简要总结
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.

研究组 & 干预措施
Standard ETT size
Their tracheas will be intubated with an appropriately sized ETT using the standard formula. The cuff will be inflated to achieve a seal by the air-leak test when holding CPAP of 20 cmH2O and the intracuff pressure will be measured using a manometer.
干预措施: Surgery less than 60 minutes (Procedure)
ETT one size smaller
Their tracheas will be intubated with an ETT that is one size smaller (instead of a 5.0 ETT, we would use a 4.0 ETT). The cuff will be inflated to achieve a seal by the air-leak test when holding CPAP of 20 cmH2O and the intracuff pressure will be measured using a manometer.
干预措施: Surgery less than 60 minutes (Procedure)
结局指标
主要结局
Intracuff pressure
时间窗: 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).
