Effects of Tracheal Tube Size on Pulmonary Aspiration

NCT01058928 · Status: UNKNOWN · Type: OBSERVATIONAL · Enrollment: 36

Last updated 2010-01-29

No results posted yet for this study

Summary

Fluid leak around the cuff is minimized when the endotracheal tube size is small relative to the size of the trachea. In the current study, the investigators assess the influence of different HVLP endotracheal tube size on fluid leakage around the cuff in a benchtop model and in anesthetized patients.

Conditions

  • The Reduction of Aspiration Rate in Intubated Patients

Interventions

OTHER

Observation of fluid leakage around tracheal tube cuffs

One milliliter of Evans blue diluted in 3.5 mL of saline solution is carefully instilled on the top of the tracheal tube cuff. In the operating room, one hour and five hours after intubation, fiberoptic bronchoscopy was performed to detect the possible presence of blue dye in the trachea. If a blue spot was seen on the trachea caudal to the tube's tip on any occasion, leakage was confirmed and the experiment was finished.
