Usually a nerve block procedure takes minutes but the part with the needle last about 1 minute. It takes another minutes to start working fully depending on the area numb, the medication used and your personal response to the medication. We always make sure the block is working before you go into the operating room.
Again, you will be given some sedation medicine to help you relax when we do the block. We will use IV and oral medications to control your pain during and after surgery. These drugs may have side effects and may or may not be as effective as a nerve block. IV and oral Pain medications will be available to you to add to the nerve block and to use as needed.
We will tell you about your options and you will decide what is best for yourself. We will advise you to have surgery with a nerve block if we think it provides the best anesthetic conditions with the least side effects. In some rare situations, general anesthesia may be riskier compared to having surgery with a nerve block. In these specific cases, we would strongly advise you to have a nerve block for surgery.
Updated visitor guidelines. Top of the page. Treatment Overview A nerve block relieves pain by interrupting how pain signals are sent to your brain. Nerve blocks may be used for several purposes, such as: To determine the source of pain. To treat painful conditions. To predict how pain will respond to long-term treatments.
For short-term pain relief after some surgeries and other procedures. For anesthesia during some smaller procedures, such as finger surgery. Nerve blocks for chronic pain may work for 6 to 12 months.
They may have to be repeated. Why It Is Done Nerve blocks are used to diagnose the causes of pain. Involves large surface areas of the body where injection with a large volume of local anesthetic might cause side effects that affect the whole body.
Involves an area of the body where injection of a local anesthetic would cause distortions that might cause problems with the surgery, such as the face. Can be done in a relatively short time. Nerve blocks may not last long enough for some procedures. Related Information Anesthesia Regional Anesthesia. Credits Current as of: May 27, Top of the page Next Section: Related Information.
The nerve block injection itself should cause minimal pain, if any. Otherwise, for certain procedures such as hand surgery, you should be able to remain awake and aware of your surroundings and free to communicate with your caregivers during surgery, if desired. This is different from general anesthesia, which would make you unconscious, and could lead to some lingering confusion and cognitive dysfunction when you wake up, especially if you are an older adult. Once your surgery is over, you may feel some heaviness or numbness from the nerve block.
If you have a single-shot nerve block, it may continue to provide pain relief for a few hours after surgery—up to 24 hours in some cases. How well the nerve block controls pain also depends on the type of operation you have—for instance, total knee replacement surgeries can cause significant pain, bruising and swelling during physical therapy, and are more difficult to recover from than, say, finger surgeries.
If there is still pain once the nerve block wears off—and you are worried about feeling pain once you go home—you can talk to your doctor about additional medication. In most cases, the doctor will prescribe pain control medication in the form of pills to take at home. There are non-opioid options available, and talk to your doctor about your preferences.
Like anything else, there are risks—although rare—associated with nerve blocks. They might include bleeding, soreness or infection at the site of the injection. Nerve injury is rare. If it happens, it is temporary in most cases, and very rarely becomes permanent.
In general, the rate of nerve injury is low, varying with the type of nerve blockade and surgery. As with any type of anesthesia or surgery, if you experience any feelings that seem unusual, you should tell your anesthesiologist right away.
