RESUMEN
Objective:To analyze the factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of postherpetic neuralgia (PHN).Methods:The medical records of PHN patients of either sex, aged 40-85 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, who received short-term electrical spinal cord stimulation from July 2017 to July 2022, were retrospectively collected. The therapeutic effect was evaluated using the modified MacNab criteria at 3 months after operation, and the patients were divided into good efficacy group (excellent and good efficacy) and poor efficacy group (fair and poor efficacy). General information, disease course, lesion site, complicated diseases, ossification of the yellow ligament in the diseased spinal segment, severity of pain in the herpetic stage, standard antiviral therapy in the herpetic stage (for more than 7 days) and use of neurotrophic drugs in the herpetic stage (for more than 7 days) were collected. Multivariate logistic regression analysis was used to screen the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN.Results:A total of 168 patients were eventually enrolled, among which 69 had poor curative effect, and the rate of poor curative effect was 41.1%. The results of multivariate logistic regression analysis showed that the patient′s age ( OR=2.230, P=0.015), course of disease ( OR=2.191, P=0.027), complication with diabetes mellitus( OR=8.859, P=0.010), ossification of ligamentum flavum at the same segment ( OR=6.602, P=0.019), severity of pain in the herpetic stage ( OR=5.788, P=0.038) and non-standard antiviral therapy in the herpetic stage ( OR=6.765, P=0.021) were the influencing factors for the poor effect of electrical spinal cord stimulation in the treatment of PHN. Conclusions:Age, course of disease, complication with diabetes mellitus, ossification of ligamentum flandum at the same segment, severity of pain in the herpetic stage and non-standard antiviral therapy in the herpetic stage are the factors influencing the poor effect of short-term electrical spinal cord stimulation in the treatment of PHN.
