摘要: 目的 探讨手法复位与全自动设备复位在良性阵发性位置性眩晕(BPPV)治疗上的差异性，为临床上选择BPPV治疗方法提供循证医学依据。方法 选取202例BPPV患者，采用随机数字表法分为两组，A组102例实施手法复位，B组100例实施全自动设备复位，并在复位治疗后7~10 d复诊。评估两组间治疗总体有效率、视觉模拟量表(VAS)评分、不良反应发生率、治疗时间的差异性。结果 A、B组总体有效率分别为98.03%和91.00%，两组比较差异有统计学意义(P=0.027)；A、B组治疗前后VAS评分差值分别为6(4)分和5(3)分，两组比较差异有统计学意义(P=0.002)；A、B组不良反应发生率分别4.90%和8.00%，两组比较差异无统计学意义(P=0.37)；A、B组治疗时间分别为6.0(1.0) min和8.0(2.0) min，两组比较差异有统计学意义(P < 0.01)。结论 手法与全自动设备复位均可有效改善BPPV患者的临床症状，但是对于有经验的临床医生来说仍建议选择手法复位。

Abstract: Objective To investigate the difference between manual reduction and automatic device reduction in the treatment of benign paroxysmal positional vertigo(BPPV), and to provide evidence-based medicine for the clinical choice of BPPV treatment.Methods Two hundred and two BPPV patients who came to the hospital for diagnosis and treatment were collected and divided into two groups by random number table method. Group A had 102 cases for manual reduction, and group B had 100 cases for automatic device reduction. Both groups were given the same medicine-assisted treatment. All patients were followed up 7 to 10 days after reduction treatment. To evaluate the differences in the overall effective rate of treatment, visual analog scale(VAS), incidence of adverse reactions, treatment time were compared between the two groups.Results The overall effective rate was 98.03% and 91.00% in group A and group B, respectively, group A was slightly higher than group B(P=0.027); the difference in VAS scores before and after treatment: group A was 6(4) points, group B was 5(3), group A is greater than group B(P=0.002); adverse reaction rates in groups A and B were 4.90% and 8.00%, respectively, group B was slightly higher than group A(P=0.37); treatment time: group A 6.0(1.0) min in group A and 8.0 (2.0) min in group B, group A was significantly shorter than group B(P < 0.01).Conclusion Both manual and fully automatic device reduction can effectively improve the clinical symptoms of BPPV patients, but for physicians with extensive clinical experience it is recommended to choose manual reduction. -
