摘要
目的:比较两种方法用于预测困难插管的临床价值。方法:672例全麻病人在术前分别采用Mallampati分级和Wilson综合风险评估法对所有病人进行评估,并比较他们的敏感度、阳性预测价值、假阳性率、假阴性率。结果:共有18例病人为真正的困难插管,Mallampati分级预测为122例,Wilson法预测为60例。阳性预测价值Wilson法明显优于Mallampati法(分别为11.8％、5.4％,P<0.01),敏感度、假阳性率、假阴性率无明显差别。结论:这两种方法用于预测成人的困难插管临床价值较低,仅适应于初步判断。
Objective: To evaluate the clinical value of two methods of predicting difficult laryngoscopy. Methods: Mallampati class and Wilson risk sum were determined before operation and laryngeal view graded in 672 patients. Results: Of all the patients, the trachea proved difficult to intubate in 18(2.7%). Positive predictive value with Wislon risk sum(11.8%) was greater than that with Mallampati class(5.4%)(P<0.01). Sensitivities、false positive rate and false negative rate were similar. Conclusion: Although Wilson risk sum was a little better than Mallampati class for assessment of the airway, noting that both tests have poor sensitivities.
