良性阵发性位置性眩晕复位后残余症状的危险因素分析

Analysis on the risk factors of residual symptoms after reduction of benign paroxysmal positional vertigo

摘要

摘要:
目的分析影响良性阵发性位置性眩晕（BPPV）复位后残余症状的危险因素。
方法选取行手法成功复位的BPPV病人120例，根据有无残余症状分为未残余组和残余组，采用logistic回归分析筛选BPPV复位后残余症状的独立危险因素。采用ROC曲线评价各指标的预测价值。
结果2组病人的性别、病因、受累侧及受累半规管等影响因素之间差异无统计学意义（P>0.05），而年龄、有无基础疾病、症状持续时间、SAS评分、复位次数及是否应用视频眼震电图（VNG）等影响因素之间差异有统计学意义（P < 0.05）；logistic回归分析结果显示，年龄、基础疾病、复位次数以及是否应用VNG是BPPV复位后残余症状的独立危险因素，各指标ROC曲线下面积分别为0.778、0.634、0.365、0.357。
结论有基础疾病且复位超过3次的病人易发生残余症状，应用VGN的病人需密切关注残余症状，年龄偏大的病人应更加重视。

Abstract:
ObjectiveTo analyze the risk factors of residual symptoms after reduction of benign paroxysmal positional vertigo(BPPV).
MethodsA total of 120 BPPV patients with successful reduction were divided into the non-residual group and residual group according to the presence or absence of residual symptoms.The independent risk factors of residual symptoms were analyzed using logistic regression analysis after BPPV reduction.The ROC curve was used to evaluate the predictive value of each index.
ResultsThe differences of the gender, etiology, affected side and affected semicircular canal were not statistically significant(P>0.05), while the differences of the age, presence or absence of underlying disease, duration of symptoms, SAS score, number of resets and VNG use were statistically significant between the two groups(P < 0.05).The results of logistic regression analysis showed that the age, basic disease, number of reductions and VNG use were the independent risk factors of residual symptoms after BPPV reduction.The area under ROC curve of each index were 0.778, 0.634, 0.365 and 0.357, respectively.
ConclusionsThe patients with underlying diseases and more than 3 times of reduction are prone to have residual symptoms.The residual symptoms in patients applying VGN should be paid close attention to, especial for the elderly.
