What Is a Nerve Block?
A nerve block is a procedure that involves injecting medication near a specific nerve or group of nerves to block pain signals from reaching the brain. It is commonly used for pain relief, particularly in surgical procedures or to manage chronic pain conditions. Nerve blocks can be temporary or long-lasting, depending on the type of medication used and the purpose of the procedure.
What Do Nerve Blocks Treat?
Nerve blocks are a versatile treatment option used to manage various ailments, primarily those associated with pain. They are particularly effective for both acute (short-term) and chronic (long-term) pain management and can treat a wide array of conditions.
How Does the Procedure Work?
Administering a nerve block is a precise and often minimally invasive procedure that involves injecting an anesthetic or anti-inflammatory medication near specific nerves or nerve clusters to block pain signals.
Here are a few common types of nerve blocks offered at pain treatment centers:
- Celiac Plexus Block – This injection is administered into the celiac plexus nerve bundle, which sends pain signals to the abdominal area. It relieves pain caused by pancreatic cancer or chronic pancreatitis.
- Genicular Nerve Block (GNB) – This block reduces pain in the arteries and nerves around the knees.
- Intercostal Nerve Block – This injection relieves pain in the chest region, usually caused by shingles.
- Lumbar Sympathetic Block (LSB) – This nerve block reduces pain in the lower back, legs, and feet.
- Stellate Ganglion Block (SGB) – This block relieves pain in the upper body, including the face, head, arms, and chest.
What Are the Risks?
Nerve blocks are generally safe when performed by experienced professionals, but there are some risks involved. Many of these risks, such as infection or bleeding, can be minimized with proper technique and patient screening.
Benefits of Nerve Blocks
Nerve blocks offer numerous benefits, particularly in pain management, surgery, and rehabilitation. One of the most significant benefits of nerve blocks is their ability to provide effective pain relief, especially in situations where other treatments may not be as effective. By targeting specific nerves or groups of nerves, a nerve block can stop pain signals from reaching the brain, providing relief from acute or chronic pain.
