Cuff leak volume as a clinical predictor for identifying post-extubation stridor

Abstract

Background: Post-extubation stridor occurs after translaryngeal intubation results to re-intubation in a number of patients.

Objective: To determine the cut-off value of the cuff leak volume test among Thai patients as a predictor for post-extubation stridor

Material and method: Demographic data and cuff leak volume were collected from patients who had been intubated with planned extubation. Clinical stridor was observed and identified after extubation.

Results: Among 115 patients, the cuff leak volume of less than 114 ml was used to predict post-extubation stridor with the sensitivity of 89%, specificity of 90%, positive predictive value of 65%, and negative predictive value of 98%, respectively. Among the stridor group, 12 of 19 cases (63.2%) needed re-intubation.

Conclusion: The cuff leak volume of less than 114 ml can be used as a clinical predictor for identifying post-extubation stridor
