Clinical Trial: High-Voltage Long-Duration Pulsed Radiofrequency Combined With Liposomal Bupivacaine Subcutaneous Block for Herpes Zoster-Associated Neuralgia

U.S., May 7 -- ClinicalTrials.gov registry received information related to the study (NCT06959147) titled 'High-Voltage Long-Duration Pulsed Radiofrequency Combined With Liposomal Bupivacaine Subcutaneous Block for Herpes Zoster-Associated Neuralgia' on April 15.

Brief Summary: Research Objectives Background and Significance: Zoster-associated neuralgia (ZAN) refers to neuropathic pain experienced by herpes zoster (HZ) patients before, during, and after rash resolution, characterized by paroxysmal, lightning-like, or knife-like sensations. Postherpetic neuralgia (PHN), a common type of chronic pain, is often accompanied by physical-psychological impairments, social dysfunction, and anxiety-depression. While high-voltage long-term pulsed ra...
