    Author: Keeratichananont W, Limthong T, Keeratichananont S.
    Journal: J Med Assoc Thai; 2012 Jun; 95(6):752-5. PubMed ID: 22774617.
    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
