How Are Nerve Blocks Administered for Pain Relief?
Nerve blocks are administered by injecting a local anesthetic or other medications directly around the targeted nerve or group of nerves. The process begins with the healthcare provider identifying the appropriate nerves responsible for the pain. Depending on the location and type of block, the procedure may involve the use of imaging guidance, such as ultrasound, fluoroscopy, or CT scans, to ensure that the needle is placed accurately near the nerve. This imaging helps reduce the risk of complications and improves the precision of the injection, especially in areas where the nerves are deep or difficult to access.
Once the needle is correctly positioned, the medication is injected. The injected solution typically includes a local anesthetic to numb the area and may also contain corticosteroids or other agents to reduce inflammation and provide longer-lasting relief. The patient may feel some initial pressure or discomfort during the injection, but this is generally brief. After the procedure, patients may experience temporary numbness or weakness in the affected area as the anesthetic takes effect. Depending on the type of nerve block, pain relief can be immediate, with effects lasting from several hours to several months, depending on the medications used and the purpose of the block.
