摘要

目的探讨改良甲颏高度预测成人患者喉镜显露困难的灵敏度和特异度。方法选取四川省盐亭县人民医院2018年1~8月择期行气管插管全身麻醉的成年患者263例，入室后分别行改良Mallampati评分（MMT）、甲颏高度测试（TMHT）、改良甲颏高度测试(MTMHT)。麻醉诱导后普通喉镜下显露声门，以喉外压迫后CormackLehane分级为Ⅲ~Ⅳ级定义为喉镜显露困难。观察3种方式预测喉镜显露困难的灵敏度、特异度

并使用受试者工作特征曲线寻找TMHT和MTMHT预测喉镜显露困难的最佳临界点及在最佳临界点的灵敏度和特异度。结果 MMT预测喉镜显露困难的灵敏度为41.3%，特异度为88.9%。TMHT预测喉镜显露困难的最佳临界点为3.9 cm

最佳临界点的灵敏度为63.2%，特异度为88.1%；MTMHT预测喉镜显露困难的最佳临界点为4.8 cm

最佳临界点的灵敏度为68.4%，特异度为87.7%。结论改良甲颏高度可准确预测患者喉镜显露困难，具有较高的灵敏度和特异度。
