Modified Jaipur block for the treatment of post-herpetic neuralgia.

Abstract

Post-herpetic neuralgia means pain which occurs for longer than one to three months after the resolution of the rash of herpes zoster. We conducted a study of 30 patients having post herpetic neuralgia. All the patients were treated with modified Jaipur block consisting of local subcutaneous infiltration of 2% Xylocaine, 0.5% bupivacaine and methylprednisolone. In our study, it was seen that 20% patients had complete relief of pain after first injection, 60% patients had complete relief of pain after second injection, 10% patients had complete relief of pain after third injection, and only 10% patients did not respond to treatment. The non-responders were either old (over 60 years) or had pain lasting for more than two years.
