不同电针刺激参数对突发性耳聋临床疗效的影响

Effect of different electroacupuncture stimulation parameters on sudden hearing loss

目的:比较不同电针频率及波型配合药物治疗与单纯药物治疗突发性耳聋(SHL)的疗效,探寻较佳电针刺激参数。方法:将118例SHL患者随机分为针药1组(30例,脱落1例)、针药2组(30例)、针药3组(31例)和药物组(27例,脱落1例)。西药组采用常规药物治疗;针药1、2、3组在药物组治疗基础上加用针刺,穴取患侧耳门、听宫、听会、风池等,并于耳门、翳风,听会、翳风交替进行电针治疗,3组分别予频率2 Hz、频率50 Hz连续波及频率2 Hz/50 Hz疏密波,每日1次。各组均治疗10 d为一疗程,治疗2个疗程。各组于治疗前后进行纯音听阈测试,并比较纯音听阈测试疗效及耳鸣、耳闷、眩晕疗效。结果:治疗后,各组纯音听阈测试值均较治疗前降低(P<0.05);针药1、2、3组纯音听阈测试总有效率均高于药物组(P<0.05),针药3组痊愈率高于药物组与针药2组(P<0.05);针药1、2、3组耳闷总有效率均高于药物组(P<0.05)。结论:在常规药物治疗基础上,加用电针能有效改善突发性耳聋患者的听力及耳闷症状,2 Hz/50 Hz的疏密波疗效更优。

Objective To compare the efficacy of different electroacupuncture(EA) frequencies and wave patterns combined with medication and medication alone for sudden hearing loss(SHL), and to explore better electroacupuncture stimulation parameters. Methods All of 118 patients with SHL were randomly divided into an acupuncture and medication group 1(group 1, 30 cases, 1 case dropped off), an acupuncture and medication group 2(group 2, 30 cases), an acupuncture and medication group 3(group 3, 31 cases) and a medication group(27 cases, 1 case dropped off). The patients in the medication group were treated with conventional medication. On the base of the medication group, the patients in the group 1, 2, and 3 were treated with acupuncture at Ermen(TE 21), Tinggong(SI 19), Tinghui(GB 2), Fengchi(GB 20), etc. on the affected side, and EA at Ermen(TE 21)-Yifeng(TE 17), Tinghui(GB 2)-Yifeng(TE 17) alternately. The 3 groups were given continuous wave with frequency of 2 Hz, continuous wave with frequency of 50 Hz, and disperse-dense wave with frequency of 2 Hz/50 Hz respectively. The treatment was given once a day, 10 days were as one course, with 2 courses in total. Before and after treatment, the pure tone hearing threshold test was performed, and the curative effect of pure tone hearing threshold test and the curative effect of tinnitus, ear fullness and dizziness were compared in the 3 groups. Results After treatment, the pure tone hearing threshold test values of each group were lower than those before treatment(P<0.05);the total effective rates of pure tone hearing threshold test in the group 1, 2, and 3 were higher than that in the medication group(P<0.05), and the cured rate of the group 3 was higher than those in the medication group and the group 2(P<0.05);the total effective rates of ear stuffiness in the group 1, 2, and 3 were higher than that in the medication group(P<0.05). Conclusion On the basis of conventional medication treatment, the addition of electroacupuncture can effectively improve the hearing and ear stuffiness symptoms of patients with SHL, and the disperse-dense wave with frequency of 2 Hz/50 Hz is more effective.
