Sympathetic Ganglion Block – Stellate

STELLATE GANGLION BLOCK PROCEDURE ( SYMPATHETIC NERVES BLOCK)

WHAT ARE STELLATE GANGLION NERVES ?

Stellate ganglion nerves, which are part of the sympathetic system, are a set of nerves that run alongside the spine. They play a crucial role in various involuntary bodily functions such as blushing, heart rate, sweating, and pupil dilation, which are not under conscious control.

WHAT IS A STELLATE GANGLION BLOCK?

A stellate ganglion block is a medical procedure that includes injecting an anesthetic to numb targeted nerve branches in the neck. It is employed to diagnose and treat various conditions related to these nerves. Some of this conditions are: complex regional pain syndrome (CRPS), postherpetic neuralgia, vascular insufficiency, and phantom limb pain. This procedure effectively alleviates pain and related symptoms in the neck, upper chest, and upper extremities. Treatment may require a series of injections.

HOW IS THE PROCEDURE PERFORMED?

To begin the procedure, you will lie on your back while receiving medication to induce relaxation. The physician will then administer a local anesthetic to numb the skin and tissues in your neck. Using a guided x-ray device called a “fluoroscope,” the physician carefully inserts a needle and directs it towards the nerves of the stellate ganglion. In certain cases, a contrast dye may be injected to ensure accurate needle placement.

Once the needle is correctly positioned, the physician delivers the medication, which bathes the nerves. This medication serves to numb the nerves, reduce inflammation, and alleviate any associated pain. Depending on your specific needs, the injection may also provide additional benefits.

When the procedure is complete, the physician removes the needle and covers the injection site with a bandage. You will be monitored for a brief time before being allowed to return home.

WHAT ARE THE EFFECTS OF  THE PROCEDURE?

Following the procedure, several temporary effects are commonly experienced. The arm on the side where the injection was administered may feel warm and tingly, and there might be hoarseness in your voice. You may also notice nasal congestion, a flushed face, and a droopy eye. These effects are normal and typically subside within a few hours. Depending on your condition, additional injections may be necessary in the future.
