A nerve block is the administration of local anesthesia near a specific nerve or group of nerves to alleviate pain. A nerve block treatment commonly treats back, leg, arm, buttock, neck, and face discomfort. Depending on the kind, a nerve block Houston might last anywhere from 8 to 36 hours. Sensation and mobility in that area of the body will eventually return. In certain situations, your doctor may use a nerve catheter to constantly provide numbing medicine to the nerve for two to three days after surgery. A tiny tube is inserted beneath the skin, close to the nerve. This is connected to the infusion pump, which distributes the anesthesia for a set amount of time.
How to prepare for a nerve block
A nerve block does not require any particular preparation. You can ingest and normally drink before the operation. Take no anti-inflammatory medications, such as ibuprofen (Advil) or naproxen, for at least 24 hours after your nerve block surgery. Before arranging a nerve block, notify your doctor if you are using blood thinners such as aspirin (Bufferin), heparin, or warfarin (Coumadin). If you have a nerve block for surgery, your doctor may give instructions to follow before the procedure, primarily if many forms of anesthesia are used. This might entail avoiding eating or drinking anything 6 to 12 hours before surgery. Before your procedure, confirm these recommendations with your specialist. You are also recommended to arrange for someone to drive you home after the surgery.
Is a nerve block permanent?
The majority of surgical nerve blocks are permanent. However, they are frequently reserved for rare cases of chronic pain in which no other therapies are effective, such as cancer pain or chronic regional pain syndrome. The nerve itself is entirely killed in a permanent nerve block by either deliberately cutting it, removing it, or destroying it with minor electrical currents, alcohol, phenol, or cryogenic freezing. Nonetheless, not all permanent nerve destruction operations are successful. Because the nerve may renew or heal, it may only last a few months. The pain may return as the nerve regenerates, but it is also conceivable that it may not.
Risks involved during the procedure
Nerve blocks are typically safe. The operation carries certain dangers, although they are uncommon. The region where the injection was administered may bleed and hurt. Infection is also a possibility. A doctor may have trouble determining the right nerve when two nerves are near one another. Additionally, the medication can reach the bloodstream. Temporary nerve blocks can very rarely result in long-term nerve damage. The nearby nerves may potentially sustain injury from the treatment. It’s also crucial to remember that these hazards are pretty uncommon and that nerve blockers are typically both safe and effective.
There are several solutions for pain alleviation. While your physician will frequently strongly recommend one treatment over another, you may have an alternative between other forms of anesthetics, including a nerve block, in some situations. Talk to your specialist to learn more about the advantages and disadvantages of each pain treatment approach. Additionally, your doctor and anesthesiologist will consult you to assess if a nerve block would give the greatest anesthetic conditions with the fewest side effects for your specific scenario.
Your doctor will probably suggest therapy or more testing if a nerve block is used as a diagnostic tool, depending on how your pain responds to the block. Call Hui Kang, MD, to schedule your appointment to learn more about nerve block procedures.
