不同针刺时间对小儿脑瘫听觉障碍的临床研究

Clinical Observation of Acupuncture of Different Time Span for Hearing Disorder in Kids with Cerebral Palsy

目的为针刺治疗小儿脑瘫听觉障碍最佳针刺时间提供较佳的临床依据。方法将90例符合纳入标准的患者随机分为3组,每组30例,A组治疗30 min,B组治疗45 min,C组治疗1 h。根据治疗前后脑干听觉诱发电位(BAEP)的评估,观察各组治疗前后患者的听力改善情况。结果 3组治疗后BAEP检测与各组治疗前比较,结果显示I、Ⅲ、V波波形的潜伏期及峰间期均缩短(P<0.01),这进一步说明针刺疗法在治疗脑瘫患者听觉障碍方面疗效显著。治疗后3组BAEP检测结果组间比较显示,A组疗效明显优于B组、C组(P<0.05);B组与C组比较差异无统计学意义(P>0.05)。表明最佳针刺时间为针刺30 min。结论在针刺手法相同的条件下,针刺30 min治疗小儿听力障碍疗效较好。

Objective To provide clinical evidence for the optimal acupuncture time in acupuncture treatment of hearing disorder in kids with cerebral palsy.Method Ninety eligible patients were randomized into 3 groups, 30 in each group. Group A was treated for 30 min, group B for 45 min, and group C for 1 h. The hearing improvement was evaluated by using brain-stem auditory evoked potential （BAEP）.Result The detection of BAEP showed that the latent and peak periods of wave I,Ⅲ, and V were significantly shortened in the 3 groups after intervention （P〈0.01）, suggesting that acupuncture can produce a marked efficacy in treating hearing disorder in cerebral palsy. The inter-group comparisons showed that the efficacy of group A was significantly higher than that of group B and C （P〈0.05）; there was no significant difference in comparing the efficacy between group B and C （P〉0.05）. It’s indicated that the optimal acupuncture time span should be 30 min.Conclusion With the same acupuncture skills, acupuncture for 30 min can produce a comparatively higher efficacy in treating infantile hearing disorder.
