NB-UVB联合罗哌卡因脊神经根阻滞治疗带状疱疹后遗神经痛疗效观察

目的：观察窄谱中波紫外线（NB-UVB）联合罗哌卡因脊神经根阻滞对带状疱疹后遗神经痛（PHN）的治疗效果。方法：选择带状疱疹后遗神经痛的患者60例,按随机原则分为治疗组（30例）和对照组（30例）,两组均给予罗哌卡因脊神经根阻滞,治疗组加用NB-UVB对受累的部位进行局部照射治疗。采用视觉模拟评分法（VAS法）,分别在治疗1个月后及出院后6个月进行VAS评分,评估两种方法的疗效和安全性。结果：治疗1个月后,治疗组有效率达96.67%,对照组有效率为80.00%,两组比较差异有统计学意义（χ2=4.043,P〈0.05）。出院后6个月时,治疗组疼痛消失者20例（66.67%）,疼痛减轻者2例（6.67%）,疼痛无缓解者1例（3.33%）;对照组疼痛消失者10例（33.33%）,疼痛减轻者5例（16.67%）,疼痛无缓解者8例（26.67%）,差异有统计学意义（P〈0.05）。结论：局麻药物罗哌卡因应用于脊神经根阻滞,对于PNH患者有明显缓解疼痛效果,NB-UVB联合罗哌卡因脊神经根阻滞治疗PNH,明显降低了PNH患者VAS评分,疗效明显优于单一治疗神经根阻滞。

Observation on treating postherpetic neuralgia with narrow-band Ultraviolet B and spinal nerve root block with ropivacaine

Objective： To evaluate the clinical therapy efficacy of postherpetic neuralgia with narrow-band Ultraviolet B （NB-UVB） and spinal nerve root block with ropivacaine. Methods： Sixty cases with postherpetie neuralgia were randomly divided into two groups. The patients in test group were treated with a combination of NB-UVB and spinal nerve root block with ropivacaine, the control group were treated with spinal nerve root block with ropivacaine alone. Two groups were evaluated the efficacy and safety by visaual analogue scale, at one month after treatment and six months from hospital. Results： At one month afer treatment, the effective percentage of the test group was 96.67%, but the control was 80.00%, the two groups was a significant gender difference （X^2=4.043, P〈0.05）. At six months after hospital, the test group of pain vanished 20 cases, alleviated 2 cases, never relieved 1 case; the control group of pain vanished 10 cases, alleviated 5 cases, never relieved 8 cases. The difference of two groups was a statistical significance （P〈0.05）. Conclusion： The paitients of PNH were obvious pain relief effects by spinal nerve root block with ropivacaine. The method of a combination of NB-UVB and spinal nerve root block with ropivacaine in PNH patients obviously reduced the patients＇VAS mark, and clearly better than nerve root block alone.
