Brief Summary

Herpes zoster (HZ) is a painful, eruptive, viral condition results from reactivation of the latent varicella zoster virus after the primary infection. The selection of an effective analgesic method in the acute phase of herpes zoster can decrease the incidence of postherpetic neuralgia by reducing neural sensitization. The stellate ganglion is present in 80% of the general population and is composed of the inferior cervical ganglion and the first thoracic ganglion fusion. It lies anterior to the neck of the first rib and extends to the inferior aspect of the transverse process of C7. The erector spinae plane (ESP) block has been reported to provide diffuse and effective analgesia in the cervical, thoracic, and lumbar regions.

Detailed Description

Especially for elderly patients, when cell-mediated immunity wanes, common symptoms of HZ appear, primarily as pain in a dermatomal distribution with a burning, sharp pain sensation (paresthesia) and itching, in addition to development of a vesicular rash. The selection of an effective analgesic method in the acute phase of herpes zoster can decrease the incidence of postherpetic neuralgia by reducing neural sensitization. The sympathetic fibers for the head, neck, heart, and upper limbs arise from the first thoracic segments, ascend through the sympathetic chain, and synapse in the superior, middle, and inferior cervical ganglions. The stellate ganglion is present in 80% of the general population and is composed of the inferior cervical ganglion and the first thoracic ganglion fusion. It lies anterior to the neck of the first rib and extends to the inferior aspect of the transverse process of C7. The erector spinae plane (ESP) block has been reported to provide diffuse and effective analgesia in the cervical, thoracic, and lumbar regions.

GroupInterventionDescription
Ultrasound-Guided Stellate Ganglion BlockUltrasound-Guided Stellate Ganglion BlockTen milliliters of a local anesthetic solution (bupivacaine (0.25%)+ 8 mg dexamethasone) is injected until the fluid spreads along the paravertebral fascia to the stellate ganglion.
Group III T2 T3 (High Thorathic) ErectroSpinae Plan BlockT2 T3 (High Thorathic) ESP Blockocal anesthetic drugs(0.2-0.3ml/kg of bupivacaine 0.25% 8mg Dexamethazone) will be administered as standard in all patients aiming to distribute within the plane between the anterior fascia of the erector spinae muscle and the transverse process.
