Clinical Observation of Treating PHN by Dorsal Root Ganglia Radio Frequency Combined Ozone / 医学研究杂志

ABSTRACT

Objective To compare the curative effect of treating postherpetic neuralgia (PHN) by dorsal root ganglia pulsed radiofrequency combined ozone and simple dorsal root ganglia pulsed radiofrequency.Methods 68 cases of chest and back PHN patients in accordance with incorporation standard were randomly divided into two groupscontrol group (n =34) received dorsal root ganglia pulsed radiofrequency while experimental group (n =34) received dorsal root ganglia pulsed radiofrequency combined ozone.The visnal analogue scale (VAS) of two groups before treatment,and 1,3,7 days,1,3 and 6 months after treatment was observed and compared;the clinical treatment effect was evaluated.Results VAS of two groups after treatment all declined obviously compared with that before treatment (P =0.000).Compared with control group,the VAS of experimental group 1 and 3 days after treatment was not significantly different (P＞ 0.05).However,the VAS 7 days,1 and 3 months after treatment declined obviously (P ＜ 0.05).The obvious effect rate of experimental group was higher than control group,so the difference was statistically different (P ＜ 0.05).Patients in both of the groups obtained satisfying curative effect,among which the effective rates of control group and experimental group were 85.29％ and 91.18％ separately.The difference was not statistically different (P ＜ 0.05).But the obvious effect rate of experimental group (70.59％) was higher than control group (38.24％),and the difference was statistically different (P ＜ 0.05).Conclusion Both dorsal root ganglia pulsed radiofrequency combined ozone and simple dorsal root ganglia pulsed radiofrequency generate effect in treating postherpetic neuralgia.But the curative effect of dorsal root ganglia pulsed radiofrequency combined ozone is superior to simple dorsal root ganglia pulsed radiofrequency within medium and long term;therefore,it is a safe and effective treatment.
