BackgroundAs the most common long-term complication of herpes zoster (HZ), postherpetic neuralgia (PHN) is characterized by chronic, persistent, and debilitating neuropathic pain. PHN seriously harms human health and currently becomes a topic of clinical importance. To date, the common methods of pain management in PHN include external therapies of traditional Chinese medicine and surgical treatments. However, there is no high-quality or direct evidence of their comparative effectiveness. This review aims to provide a network meta-analysis to compare the efficacy of external therapies of traditional Chinese medicine and surgical treatments in the pain management of PHN.MethodsDatabases such as PubMed, Cochrane Central Register of Controlled Trials, EMBASE, China National Knowledge Infrastructure, China Biology Medicine Disc will be searched for relevant randomized controlled trials to obtain literatures on the treatment of PHN with external therapies of traditional Chinese medicine and surgical treatments, and clinical randomized controlled trials will be screened out from their inception to August 5, 2022. The participant intervention comparator outcomes of this study are as flowing: P, patients with PHN; I, external therapies of traditional Chinese medicine and surgical treatments; C, no treatment, pharmacological placebo, treatment as usual or sham acupuncture groups; O, primary outcome is pain intensity, and secondary outcomes are onset of pain relief time, quality of life, therapeutic effective rate and reverse effects. Cochrane Risk of Bias Tool will be used in assessing literature's quality. Network meta-analyses will be conducted to generate estimates of comparative effectiveness of each intervention class and rankings of their effectiveness, in terms of pain management.ResultThis systematic review and network meta-analysis will provide evidence of the efficacy of different therapeutic methods for pain management in PHN, to show which forms of therapy are more commonly used with higher effectiveness.DiscussionThe results will systematically provide suggestions for medical practitioners to choose effective, time-saving and economical pain management method for PHN.Copyright © 2022 the Author(s).
