A Study on the Efficacy and Safety of Intravenous Lidocaine Infusion Combined with Pulsed Radiofrequency in Preventing Postherpetic Neuralgia: A Randomized, Double-Blind, Controlled Trial

Intravenous injection of lidocaine combined with pulsed radiofrequency therapy is more effective in treating acute herpes zoster neuralgia. Compared with pulsed radiofrequency therapy alone, it can significantly reduce the incidence of postherpetic neuralgia and provide more prolonged pain relief, and also improve patients' sleep disorders.
