红外视频眼震观察系统辅助下床旁三联检查与冷热试验的一致性分析

Correlation between bedside triple test by videonystagmoscope and caloric test

目的 探讨红外视频眼震观察系统（Videonystagmoscope）辅助下床旁前庭功能检查与冷热试验结果的一致性.方法 回顾性分析2014年1月至2015年5月北京协和医院耳鼻咽喉科门诊连续收治的313例以眩晕、头晕或平衡障碍为主诉的患者的临床资料.将Videonystagmoscope辅助下床旁三联检查（自发眼震、摇头试验、甩头试验）结果与视频眼震电图检查中的自发眼震和冷热试验结果进行对比,计算床旁检查结果的敏感性、特异性、阳性预测值和阴性预测值.结果 Videonystagmoscope辅助下床旁检查可以发现视频眼震电图中被忽略的Ⅰ度自发眼震.在全部313例患者中床旁三联检查方法的敏感性、特异性、阳性预测值和阴性预测值分别为65.1％、94.0％、90.5％和75.5％.结论 床旁三联检查作为一种前庭功能障碍的筛查方法简便、快速,与冷热试验具有较好的一致性.

Objective To investigate the correlation between rapid bedside triple test and caloric test. Method We reviewed clinical records of 313 consecutive patients presenting with vertigo at our earnose-throat clinic. Results of bedside vestibular tests in all patients were compared with caloric test. The sensitivity, specificity, and positive and negative predictive values for the triple test relative to caloric test were calculated. Results Compared with the caloric test results, the sensitivity, specificity, positive predictive value（PPV）, and negative predictive value （NPV） of the triple test were 65.1%, 94. 0%, 90. 5% and 75.5% , respectively. Conclusions As a predictive screening for patients with vertigo, the bedside triple test is a rapid, reliable tool for clinical diagnosis.
