Abstract

Objective. To evaluate the incidence and identify factors associated with the occurrence of post-extubation stridor and to evaluate the performance of the cuff-leak test in detecting this complication.

Design. Prospective, clinical investigation.

Setting. Intensive care unit of a university hospital.

Patients. Hundred twelve extubations were analyzed in 112 patients during a 14-month period.

Intervention. A cuff-leak test before each extubation.

Measurements and results.The incidence of stridor was 12%. When we chose the thresholds of 130 ml and 12% to quantify the cuff-leak volume, the sensitivity and the specificity of the test were, respectively, 85% and 95%. The patients who developed stridor had a cuff leak significantly lower than the others, expressed in absolute values (372±170 vs 59±92 ml, p<0.001) or in relative values (56±20 vs 9±13%, p<0.001 …
