Objective To analyze the clinical efficacy of thoracic paravertebral nerve block with ozone in the treatment of postherpetic neuralgia.Methods Eighty-five patients suffered postherpetic neuralgia were divided into 4 groups: Group A (oral drugs + intramuscular injection of vitamin B12 + local nerve block of lesion area), Group B (oral drugs + intramuscular injection of compound trivitamin B + local nerve block of lesion area), Group C (oral drugs + Skincare and Hygiene Products intramuscular injection of compound trivitamin B + thoracic paravertebral nerve block + local nerve block of lesion area), Group D (oral drugs + intramuscular injection of compound trivitamin B + thoracic paravertebral nerve block with ozone + local nerve block of lesion area).Treatment outcomes were evaluated by Visual Analogue Scale (VAS), Quality of Sleep (QS), Self-Rating Depression Scale (SDS) and C-reactive protein (CRP) before treatment and 4 weeks after treatment.Results After treatment, VAS, QS and SDS scores of 4 groups were lower than that before treatment, and the differences were statistically significant (P < 0.05, for all).
There were no significant changes in the level of CRP of group A, B, C before and after treatment (P > 0.05, for all), while a significant change in CRP was observed in patients of group D between before and after treatment (P < 0.05).The improvement of VAS, QS and SDS scores of group D was significantly better than other 3 groups (P < 0.05, for all).
Conclusion Thoracic paravertebral nerve spices block combined with ozone is a quick and effective method for postherpetic neuralgia patients.
