The cuff leak test: does it "leak" any information?
Post-extubation stridor and upper-airway obstruction are multifactorial in etiology and can occur as a result of laryngotracheal edema, intubation trauma, excessive cuff pressure with mucosal ulceration, and prolonged intubation with secondary inflammation and granuloma formation.1 Cuff leak tests (CLTs) were introduced in an attempt to predict post-extubation upper-airway obstruction and reduc...
متن کاملLimited value of the cuff-leak test.
Stridor following tracheal extubation occurs in approximately 5% of all patients, and approximately 1% of all patients require reintubation for upper-airway obstruction.1 Patients at increased risk for stridor and upper-airway obstruction following extubation include female patients; children,2 particularly those with acute respiratory-tract infections (croup);3 patients who have incurred facia...
متن کاملThe cuff-leak test: what are we measuring?
Stridor is one of the most frequent causes of early extubation failure. The cuff-leak test may help to identify patients at risk to develop post-extubation laryngeal edema. However the discrimination power of the cuff-leak test is highly variable and can be use, at best, to detect patients at risk to develop edema but should not be used to postpone extubation as tracheal extubation can still be...
متن کاملValue of the cuff leak test is limited.
We read with interest the recent Critical Care review of post-extubation laryngeal edema and stridor resulting in respiratory failure [1]. We mostly agree with the authors’ opinion in that article except that the cuff leak test (CLT) was proposed as a standard extubation algorithm. We have two reasons to disagree. First, although the CLT has been widely used for the prediction of post-extubatio...
متن کاملDeterminants of the cuff-leak test: a physiological study
INTRODUCTION The cuff-leak test has been proposed as a simple method to predict the occurrence of post-extubation stridor. The test is performed by cuff deflation and measuring the expired tidal volume a few breaths later (VT). The leak is calculated as the difference between VT with and without a deflated cuff. However, because the cuff remains deflated throughout the respiratory cycle a volum...
