甲状腺肿瘤患者气道困难的综合预测

A Comprehensive System For Predicting Difficult Airway Of Patients With Thyroid Tumor

目的:评价甲状腺肿瘤患者困难气道综合预测评分系统的可行性。方法:89例甲状腺肿瘤手术患者,对其分别进行Mallampati困难气道分级及困难气道综合预测评分系统评估,并记录手术中真正发生气道困难的病例数。计算两种预测系统的敏感度、特异度、误诊率、漏诊率,并进行比较。结果:全组89例患者,困难气道发生34例。对于甲状腺肿瘤患者困难气道的预测,综合预测评分系统敏感度为94.1%,而Mallampati分级的敏感度为55.9%,综合预测评分系统漏诊率为5.9%,而Mallampati分级的漏诊率为44.1%,两者比较,差异有统计学意义(P<0.05)。两种方法误诊率、特异度比较,差异无统计学意义(P>0.05)。结论:综合预测评分系统是预测甲状腺肿瘤患者困难气道的有效方法,可为术前识别困难病例提供依据。

Objective：To evaluate the feasibility of the comprehensive system for predicting difficult airway of patients with Thyroid Tumor. Methods： 89 patients with Thyroid Tumor were evaluated with Mallampati class, and evaluated with the comprehensive system preoperatively. The sensitivity, fail-diagnosis rate, miss-diagnostic rate and specificity of the comprehensive system were calculated and compared with the same indexes of Mallampati class. Results： Of all the 89 patients, the trachea proved difficult to intubate was 34. The sensitivity of the comprehensive system was 94.1%, While the sensitivity of Mallampati class was 55.9%, The difference was statistically significant. The miss-diagnostic rate of the comprehensive system was 5.9 %, the miss-diagnostic rate of Mallampati class was 44.1%, While the difference was statistically significant. The fail-diagnosis rate and specificity had no statistically significant difference between the two methods. Conclusion： the comprehensive system for predicting difficult airway of patients with Thyroid Tumor is one of the suitable methods to predict difficult airway of patients with Thyroid Tumor. It can help to identify difficult cases according to the result of this predicting system.
