The current study used real-time ultrasonography to evaluate the air-leak and hypothesised that the air-column width, measured by ultrasonography, may be correlated to the development of post-extubation stridor.<\/jats:p><jats:p>From June 1, 2001 to March 1, 2002, a total of 51 planned extubations in 51 consecutively intubated patients were included. All of the patients received ultrasonographical examinations of their vocal cords and larynx in addition to an air-column width measurement within 24\u2005h prior to extubation.<\/jats:p><jats:p>The overall post-extubation stridor rate was 7.8%. The air-leak volume presented as median (interquartile range) were 300 (350) mL and 25 (20) mL, respectively, for the nonstridor and stridor groups. The air-column width during cuff deflation was 6.4 (2) mm and 4.5 (0.8) mm, respectively. They were found to be statistically significant.<\/jats:p><jats:p>In conclusion, the authors demonstrated that laryngeal ultrasonography could be a reliable, noninvasive method, in the evaluation of vocal cords, laryngeal morphology and the ease of airflow, which passed through vocal cords or subglottic area due to laryngeal oedema. The air-column width during cuff deflation was a potential predictor of post-extubation stridor.<\/jats:p>","DOI":"10.1183\/09031936.06.00029605","type":"journal-article","created":{"date-parts":[[2006,2,1]],"date-time":"2006-02-01T22:54:18Z","timestamp":1138834458000},"page":"384-389","source":"Crossref","is-referenced-by-count":136,"title":["Laryngeal ultrasound: a useful method in predicting post-extubation stridor.
