Nerve block

Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of <a href="/facts/Pain_relief/El1f7CEz">pain relief</a>. 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 <a href="/facts/Corticosteroid/jeL2QeIL">corticosteroid</a>, and other agents onto or near a nerve. <a href="/facts/Neurolytic_block/AR0CzuaB">Neurolytic block</a>, the deliberate temporary degeneration of nerve fibers through the application of chemicals, heat, or freezing, produces a block that may persist for weeks, months, or indefinitely. <a href="/facts/Neurectomy/8Ex4CfuN">Neurectomy</a>, the cutting through or removal of a nerve or a section of a nerve, usually produces a permanent block. Because neurectomy of a <a href="/facts/Sensory_nerve/0JVWPqKP">sensory nerve</a> is often followed, months later, by the emergence of new, more intense pain, sensory nerve neurectomy is rarely performed.
The concept of nerve block sometimes includes central nerve block, which includes <a href="/facts/Epidural/jlVdMFPe">epidural</a> and <a href="/facts/Spinal_anaesthesia/lGtF5kRs">spinal anaesthesia</a>.
