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). Stridor was associated with an elevated Simplified Acute Physiology Score (SAPS II), a medical reason for admission, a traumatic or difficult intubation, a history of self-extubation, an over-inflated balloon cuff at admission to ICU and a prolonged period of intubation. These results provide a framework with which to identify patients at risk of developing a stridor after extubation.
CONCLUSION: A low cuff-leak volume (<130 ml or 12%) around the endotracheal tube prior to extubation is useful in identifying patients at risk for post-extubation stridor.
