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 identifi ed 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%, specifi city 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.
