手法复位治疗良性阵发性位置性眩晕患者后复发的影响因素分析

目的:研究良性阵发性位置性眩晕(BPPV)患者经手法复位治疗后复发的影响因素。方法:选取BPPV患者200例,并给予手法复位治疗,之后随访3月,统计治愈后30、60、90 d的复发情况,并分析复发危险因素。结果:183例患者完成随访。复发组和未复发组的年龄、BPPV病程、发作次数有显著性差异(P0.001)。多元Logistic回归分析发现,BPPV病程(OR=2.171,95%CI为1.194~3.946,P=0.011)、复位次数≥10次(OR=3.040,95%CI为1.249~7.403,P=0.014)是影响手法复位后BPPV复发的独立因素。结论:随着治愈后时间的推移,BPPV复发的患者例数逐渐增多。

Analysis of Influencing Factors on Recurrence of Benign Paroxysmal Positional Vertigo after Repositioning Maneuver

Objective: To investigate the influencing factors on recurrence of benign paroxysmal positional verti-go(BPPV) after repositioning maneuver. Methods: Two hundred BPPV patients were enrolled and then treated with repositioning maneuver. The vertigo recurrence within30 days, 60 days and90 days were calculated, and the influencing factors on recurrence were analyzed. Results: There were 183 patients finished 90 days follow-up. There were significant differences in age, BPPV duration, episodes numbers betweenthe recurrent group and non-recurrent group (P<0.001). Multivariate logistic regressionshowed that BPPV duration (OR=2.171, 95%CI 1.194~3.946, P=0.011) and times of repositioning maneuver≥10 (OR=3.108, 95%CI 1.254~7.702, P=0.014) were independent factors onrecurrence. Conclusion: Recurrence numbers of BPPV patients gradually increasedover the post cure time.
