Nerve block Pros and Cons

A nerve block is a procedure in which an injection is used to reduce discomfort or "turn off" a pain sensation along a specific nerve area. Your doctor may utilize imaging guidance to precisely position the needle for optimal benefit. A nerve block may provide brief pain relief and aid in identifying a more specific source of pain.

This procedure doesn't need a lot of preparation. Notify your doctor if you think you're pregnant. Take off your jewelry and wear loose, comfy clothing. It is possible that you will be required to change into a gown for the procedure.

A nerve block is a pain treatment that involves injecting anesthetics and/or anti-inflammatory medications into a specific nerve or group of nerves. The goal of the injection is to "switch off" a pain signal that is emanating from a specific site in the body or to reduce inflammation in that location, respectively.

Your doctor may utilize imaging guidance, such as ultrasonography, fluoroscopy, or computed tomography (CT or "CAT" scan), to assist in accurately positioning the needle. This will ensure that you obtain the full advantage of the injection.

Individuals suffering from acute or chronic pain may benefit from a nerve block injection to provide temporary pain relief. The spine is frequently the source of such discomfort, although the shoulders, pelvis, limbs, and extremities are also frequently impacted. A nerve block injection gives a damaged nerve time to repair after being in a constant state of discomfort. Nerve blocks can also provide diagnostic information to the clinician. By administering a nerve block and then observing your response, your doctor can ascertain the cause or origin of your pain and plan additional treatment.

Nerve block Pros and Cons

A tiny needle will be inserted through the epidermis and targeted to the injection spot by the doctor. To check needle positioning in the proper spot, a little amount of contrast material might be injected. The injection will be administered with a syringe similar to that used for normal vaccinations. A small vial of drug will be used to load the syringe by the doctor. Your doctor would prescribe medication based on your specific needs.

If image guidance is performed, more equipment will be needed around the table. Medical imaging is a non-painful procedure. It gives your doctor important images that help them position the needle in the exact appropriate spot for the injection.

A radiography table, 1 x-ray tube, and a video monitor are commonly used in this procedure. Fluoroscopy is the process of converting x-rays into video pictures. It is used by doctors to monitor and guide surgeries. The video is generated by an x-ray machine and a detector mounted above the examination table.

The CT scanner is usually a big machine that looks like a donut with a small tunnel in the middle of it. You will lay down on a table that slides in and out of this small tunnel. The x-ray tube and electronic x-ray detectors, which are situated opposite each other in a ring around you and rotate around you, are referred to as a gantry. There is a separate control room for the workstation that processes the image information. This is the area where the technologist operates the scanner and supervises your exam visually. Through the use of a speaker and microphone, the technician will be able to hear and speak with you.

Nerve block Pros

  • Temporary relief from pain caused by inflammation in the nerve's distribution.
  • It may assist the doctor in identifying a more specific source of the pain.
  • Increased capacity to work normally in daily life without the limits imposed by pain
  • Nerve blocks may be used to treat chronic or long-term pain, postoperative pain, and severe acute or short-term pain. Nerve blocks provide rapid relief from discomfort. They can also provide long-term relief since some injections minimize nerve sensitivity and allow them to recover.

Nerve block Cons

  • The injection site can get infected with microorganisms.
  • Inadvertent injection of medicament into the bloodstream
  • Spread of medicine to additional nerves that was not anticipated
  • If the nerves are close together, it is possible to accidentally hit the "wrong" nerve while attempting to block the intended nerve.
  • Low-level radiation exposure is possible when fluoroscopy or CT is performed.
