ETT Cuff Leak: TV Ratios

No results posted yet for this study

Summary

In the past 5 years cuffed endotracheal tubes (ETT) have become the standard of care in pediatrics. However, hyperinflation of the cuff can compromise the tracheal mucosal perfusion while an inadequate seal may impact ventilation and potentially increase the risk of aspiration. Hence, the goal after placement of a cuffed ETT is to create a safe and effective tracheal seal. The two ways to measure that are to hold CPAP while listening for an audible leak and measuring the difference between the inspired and expired tidal volumes (TV). This is a prospective study to compare these two methods used to create a tracheal seal and measure the intracuff pressure after a satisfactory tracheal seal is established.

Conditions

  • Surgical Procedures, Operative

Interventions

OTHER

CPAP

Sealing the airway by holding CPAP of 20 cmH2O in the anesthesia circuit and slowly inflating the cuff until no air leak is heard with a stethoscope placed in the suprasternal notch.

OTHER

Tidal volume

The ratio of the inspired to expired tidal volume will be determined using the following formula: (TVinspired - TV¬expired)/TVinspired. The peak inflating pressure (PIP) required to achieve the set TV will be noted. The air in the cuff will then be increased or decreased as needed to achieve a set delivered ratio of 0.9-1.0.
