甲状腺患者气管插管困难预测方法的评价

Evaluation of methods for predicting difficult airway of patients with thyroid tumor

目的:探讨三种困难气道预测方法在甲状腺肿瘤患者气管插管困难预测中的价值。方法:92例甲状腺肿瘤手术患者,术前应用CT行上气道扫描、Mallampati分级以及CM联合评估表进行困难气道预测。以实际行气管插管操作时发生插管困难作为金标准。计算3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92例患者,困难气道发生7例。用CT进行预测的敏感度高于Mallampati困难气道分级,差异有统计学意义。而Mallampati困难气道分级的特异度高于CT预测,差异有统计学意义。CM联合评估的敏感度与CT预测相近,差异无统计学意义,而特异度与Mallampati困难气道分级相近,差异无统计学意义。结论:CM联合评估在敏感度上与CT预测相近,在特异度上与Mallampati分级近似,敏感度和特异度都达到较好的水平。

Objective： To evaluate the value of three metnods for predicting difficult airway of patients with Thyroid Tumor. Methods： 92 patients with Thyroid Tumor were evaluated with CT, Mallampati class, and evaluated with the CM comprehensive system preoperatively. The sensitivity, fail-diagnosis rate, miss-diagnostic rate and specificity were calculated and compared. Results： Of all the 92 patients, the trachea proved difficult to intubate was 7. The sensitivity of the CT predictions was higher than Mallampati class. The specificity of the Mallarnpati class was higher than the CT predictions. The difference was statistically significant. While the sensitivity of CM comprehensive system was similar than the CT predictions,The specificity was similar than Mallampati class. The difference had no statistically significant difference. Conclusion： The sensitivity of CM comprehensive system was similar than the CT predictions. The specificity was similar than Mallampati class. Both sensitivity and specificity have good leave.
