摘要
目的评估拔管后喉喘鸣的危险因素,探讨气囊漏气试验的临床意义。方法选取某院住院的气管插管患者共311例,分析拔管后喉喘鸣的危险因素;拔管前进行气囊漏气试验。结果共311例患者,其中21例患者拔管后出现喉喘鸣,拔管后喉喘鸣的Logistic回归分析显示女性,气管插管时间≥1周,困难气管插管为气管插管患者拔管后喉喘鸣的独立危险因素;气囊漏气试验敏感度与特异度分别为71.4%和79.7%。结论女性,插管时间≥1周,困难气管插管为气管插管患者拔管后喉喘鸣的独立危险因素;气囊漏气试验预测拔管后喉喘鸣有较高的敏感度与特异度。
Objective To investigate the risk factors of post-extubation stridor and the clinical significance of cuff leak test.Me thods 311 patients admitted in a hospital who were intubated were selected and the risk factors of post-extubation stridor were analyzed.The cuff leak test was given before extubation.Re s ults Of the 311 patients,21 had post-extubation stridor.Logistic regression analysis showed that female,duration of intubation being or more than one week,difficulty intubation were independent risk factors of post-extubation stridor.The sensitivity and the specificity of the cuff leak test were 71.4% and 79.7% respectively.Conclus ion Female,duration of intubation being or more than one week,difficulty intubation were independent risk factors of post-extubation stridor.The method of cuff leak test provides high sensitivity and specificity in predicting post-extubation stridor.
