CT引导下脉冲射频联合连续神经阻滞治疗顽固性带状疱疹后神经痛的临床疗效研究

CT-guided pulsed radiofrequency combined with continuous nerve block for the treatment of refractory postherpetic neuralgia:a clinical study

目的探究CT引导下脉冲射频联合连续神经阻滞治疗顽固性带状疱疹后神经痛(PHN)的临床疗效。方法选取2021年1月至2023年1月本院收治的208例顽固性PHN患者为对象,随机数表法分为联合组和对照组,每组各104例。对照组接受CT引导下脉冲射频治疗,联合组在对照组的基础上行连续硬膜外神经阻滞治疗。比较两组患者不同时间点疼痛情况、临床有效率、镇痛补救情况、睡眠质量,血清高迁移率族蛋白B1(HMGB1)、白细胞介素-1β(IL-1β)和白细胞介素-10(IL-10)水平。结果随访期间,4例患者失访。最终纳入联合组103例,对照组101例。联合组治疗总有效率为89.32%,明显高于对照组的78.22%(P<0.05)。患者疼痛视觉模拟量表(VAS)评分、阿森斯失眠量表(AIS)评分的时间、组间、时间与组间交互效应差异均具有统计学意义(P<0.05);治疗后1、2、4周联合组VAS、AIS评分均低于对照组(P<0.05);联合组镇痛补救次数低于对照组,曲马多使用剂量少于对照组(P<0.05);治疗后4周联合组血清HMGB1、IL-1β、IL-10水平均低于对照组(P<0.05)。结论CT引导下脉冲射频联合连续神经阻滞治疗顽固性PHN,能有效减轻神经炎性损伤,改善患者疼痛症状,提高睡眠质量,其镇痛效果及临床疗效优于单纯使用CT引导下脉冲射频疗法。

Objective To investigate the clinical efficacy of CT-guided pulsed radiofrequency combined with continuous nerve block in the treatment of refractory postherpetic neuralgia(PHN).Methods A total of 208 patients with refractory PHN,who were admitted to the Hengshui Municipal People's Hospital of China between January 2021 and January 2023,were selected as the subjects of study.Using random number table method,the patients were divided into combination group and control group,with 104 patients in each group.The patients of control group received CT-guided pulsed radiofrequency therapy,and the patients of combination group received additional continuous nerve block therapy on the basis of the treatment of control group.The pain degree at different time point,clinical effective rate,number of analgesia remedy times,quality of sleep,and the levels of serum high mobility group box 1(HMGB1),interleukin-1β(IL-1β)and interleukin-10(IL-10)were compared between the two groups.Results During the follow-up period,4 patients were lost in touch.Finally,103 patients were included in the combination group and 101 patients were included in the control group.The total treatment response rate in the combination group was 89.32%,which was significantly higher than 78.22%in the control group(P<0.05).There were statistically significant differences in visual analogue scale(VAS)scores and Athens insomnia scale(AIS)scores including the time effect,intergroup effect and time-group interaction effect,between the two groups(P<0.05).The postoperative one-week,2-week,4-week VAS scores and AIS scores in the combination group were remarkably lower than those in the control group(P<0.05).The number of analgesia remedy times in the combination group was smaller than that in the control group,and the used dosage of tramadol in the combination group was lower than that in the control group(P<0.05).Four weeks after treatment,the serum levels of HMGB1,IL-1βand IL-10 in the combination group were lower than those in the control group(P<0.05).Conclusion For the treatment of refractory PHN,CT-guided pulsed radiofrequency combined with continuous nerve block can effectively alleviate neural inflammatory damage,and improve pain symptoms and sleep quality,besides,its analgesic effect and clinical efficacy are superior to CT-guided pulsed radiofrequency alone.
