  2. Nerve block - Wikipedia

    en.wikipedia.org/wiki/Nerve_block

    Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic nerve block (sometimes referred to as simply "nerve block") is a short-term block, usually lasting hours or days, involving the injection of an anesthetic, a corticosteroid, and other agents onto or near a nerve.

  3. Spinal anaesthesia - Wikipedia

    en.wikipedia.org/wiki/Spinal_anaesthesia

    Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, [1] is a form of neuraxial regional anaesthesia involving the injection of a local anaesthetic or opioid into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.

  4. Local anesthetic - Wikipedia

    en.wikipedia.org/wiki/Local_anesthetic

    Many local anesthetics fall into two general chemical classes, amino esters (top) and amino amides (bottom). A local anesthetic (LA) is a medication that causes absence of all sensation (including pain) in a specific body part without loss of consciousness, [1] providing local anesthesia, as opposed to a general anesthetic, which eliminates all sensation in the entire body and causes ...

    However, the supraclavicular block is often quicker to perform and may result in fewer side effects than the interscalene block. Compared to the infraclavicular block and axillary blocks, the successful achievement of adequate anesthesia for surgery of the upper extremity is about the same with supraclavicular block.

  6. Neurolysis - Wikipedia

    en.wikipedia.org/wiki/Neurolysis

    When the nerve fibers degenerate, it causes an interruption in the transmission of nerve signals. In the medical field, this is most commonly and advantageously used to alleviate pain in cancer patients. [1] The different types of neurolysis include celiac plexus neurolysis, endoscopic ultrasound guided neurolysis, and lumbar sympathetic ...

  7. Lumbar nerves - Wikipedia

    en.wikipedia.org/wiki/Lumbar_nerves

    The third lumbar spinal nerve (L3) [3] originates from the spinal column from below the lumbar vertebra 3 (L3). L3 supplies many muscles, either directly or through nerves originating from L3. They may be innervated with L3 as single origin, or be innervated partly by L3 and partly by other spinal nerves. The muscles are: quadratus lumborum ...

  8. Nerve compression syndrome - Wikipedia

    en.wikipedia.org/wiki/Nerve_compression_syndrome

    Nerve compression syndrome, or compression neuropathy, or nerve entrapment syndrome, is a medical condition caused by chronic, direct pressure on a peripheral nerve. [1] It is known colloquially as a trapped nerve , though this may also refer to nerve root compression (by a herniated disc , for example).

  9. Local anesthesia - Wikipedia

    en.wikipedia.org/wiki/Local_anesthesia

    Plexus block Adverse effects depend on the local anesthetic method and site of administration discussed in depth in the local anesthetic sub-article, but overall, adverse effects can be: localized prolonged anesthesia or paresthesia due to infection, hematoma , excessive fluid pressure in a confined cavity, and severing of nerves & support ...
