颈2椎旁与颈椎硬膜外神经阻滞治疗颈源性头痛的对照研究

目的对比颈2椎旁和颈椎硬膜外神经阻滞治疗颈源性头痛的疗效。方法按照国际诊断颈源性头痛的标准，选择62例颈源性头痛患者，随机分为A、B两组。A组33例，行颈2椎旁神经阻滞；B组29例，行颈椎硬膜外神经阻滞，两组均每周一次，4次为1个疗程。用数字评分法评估和对照两组患者治疗前后的疼痛程度及疗效。结果A、B两组治疗优良率分别为90．91％和68．97％，两组疗效比较有显著性差异（P〈0．05）。结论应用颈2椎旁神经阻滞和颈椎硬膜外神经阻滞治疗颈源性头痛均有疗效，但前者疗效明显优于后者。

Cervical 2 Paravertebral Block and Cervical Epidural Block for Cervicogenic Headache:A Comparison Between the Two Methods

Objective To evaluate the efficacy of the cervical 2 paravertebral block and cervical epidural block in cervicogenic headache. Methods According to the international diagnostic criteria of cervicogenic headache,62 patients who had cervieogenic headache were randomised in two groups. In group A 33 patients performed cervical 2 paravertebral block. In group B 29 patients performed cervical epidural block. Both of the groups were performed once a week ,four as a course of treatment. To compare the efficacy and pain degree（before and after treatment） using numerical rating scale（NRS） in the two groups. Results The effective power of group A was 90.91%,group B was 68.97%, the efficacy of two groups had significant difference（P〈 0.05）. Conclusion Both cervical 2 paravertebral block and cervical epidural block for cervicogenic headache were useful, but the former were better than the latter.
