Study Overview
Brief Summary
Based on standard and historical practice, the predictive size of the endotracheal tube (ETT) to be used in children has been based on various formulas. However, no study has clearly compared these formulas to determine the optimal size of cuffed ETTs. Furthermore, they were developed when using a polyvinylchloride cuff and not the thinner polyurethane cuff which is in common clinical use today. Hence, the purpose of this current study is to evaluate which of the currently available formulas most closely predicts the appropriate size of cuffed ETT to be used based not only on the fit within the trachea, but more importantly the intracuff pressure after the cuff is inflated to seal the airway.

Inclusion Criteria

Outcomes
Primary Outcomes
Number of participants that needed their ETT exchanged
Time Frame: Immediately following intubation
Having to remove the original ETT and replacing it with a smaller or larger size due to excessive air leak or excessive pressure in the cuff.
Secondary Outcomes
No secondary outcomes reported
