Acute Pain Relief by Superficial Cervical Plexus Block in the Patient with Herpes Zoster

Abstract

Herpes zoster is a disease that causes a skin rash with blisters and extreme pain along mainly the unilateral dermatome. It often occurs in the thoracic nerve area, but can also occur in the cranial, cervical, and lumbar nerve areas. It is not clear that the interventions such as nerve block or subcutaneous local anesthetics result in a lower incidence of postherpetic neuralgia than the natural course of herpes zoster. However, the severity of acute pain is known as a risk factor for postherpetic neuralgia. There have been many studies on the epidural block or paravertebral block for acute pain control of herpes zoster, but superficial cervical plexus block has not been widely applied. We performed a superficial cervical plexus block to alleviate the acute pain of herpes zoster in the neck and obtained the expected result, so we present it with a literature review.
