Abstract:Objective A retrospective analysis of the clinical effects of high-field pulsed radiofrequency in treating diabetes complicated with postherpetic neuralgia (PHN). Methods 83 patients with postherpetic neuralgia, from June 2017 to June 2019, were divided into two groups: diabetic group and non-diabetic group. Patients were received high-field pulsed radiofrequency combined drug therapy.The numeric rating scale (NRS) , postoperative medication and the quality of sleep(QS)were calculated at pre-treatment, and 1week, 1 month, 3 months and 6 months of post-treatment in all patients. Results Compared with pre-treatment,the scores of NRS were signi?cantly decreased in both groups (P< 0.05). Follow-up for 6 months, 1 case was lost to follow-up, 83 cases completed follow-up. The improvement of NRS in the diabetic group at 1week, 1 month, 3 months and 6 months after surgery was significantly lower than that of the non-diabetic group (P< 0.05). Compared with the non-diabetic group, the usage rate of medicine was no significantly different from the diabetic group decreased 6 months of post-treatment (P>0.05). The quality of sleep was significantly lower in the non-diabetic group than that in the diabetic group at 6 months after the treatment (P<0.05). Conclusion High-field pulsed radiofrequency treatment is effective for patients with diabetes and PHN, but the effect is not as good as for patients with PHN alone.
