A method of analgesia in which a nerve-destroying agent is injected close to the affected nerve.
Injection of anesthetic into peripheral nerves or nerve trunks to interrupt sensation.
A method of making an area of the body numb and pain-free by injecting anesthetic medication around the nerves that control sensation in the area. A nerve block is performed when it is not possible to inject an anesthetic agent directly into the area being treated because of an inflammation or the risk of infection. Or, if the area that needs to be anesthetized is very large, anesthesia of the legs and lower part of the body can be achieved by blocking the lower spinal nerves with spinal or epidural anesthesia or a caudal block.
A method of producing anesthesia in part of the body by blocking the passage of pain impulses in the sensory nerves supplying it. A local anesthetic, such as procaine, is injected into the tissues in the region of a nerve. In this way anesthesia can be localized, so that minor operations can be performed without the necessity of giving a general anesthetic.
The induction of regional anesthesia by preventing sensory nerve impulses from reaching the central nervous system. This is usually done by injecting an anesthetic solution (e.g., lidocaine) into a peripheral nerve or by electrically stimulating the nerve.
A procedure used to relieve otherwise intractable spasticity, including painful flexor spasms. An injection of phenol into the affected nerve interferes with the function of that nerve for up to 3 months, potentially increasing a person’s comfort and mobility.
Injecting a local anesthetic around a nerve is done to induce numbness in a specific body area served by that nerve. For instance, the palm of the hand can be anesthetized by administering injections along the arm to block the ulnar and median nerves.
A nerve block procedure is undertaken when directly injecting anesthetic into the affected tissues is not feasible due to painful inflammation or the potential for spreading infection in the area.
This technique can also be employed to numb a broad region or an area that isn’t suitable for injection due to its deep location within the body or being covered by bone.
