![]() Local anesthetic is often combined with other drugs to potentiate or prolong the analgesia produced by the nerve block. Main article: Local anesthetic nerve block The concept of nerve block sometimes includes central nerve block, which includes epidural and spinal anaesthesia. Because neurectomy of a sensory nerve is often followed, months later, by the emergence of new, more intense pain, sensory nerve neurectomy is rarely performed. Neurectomy, the cutting through or removal of a nerve or a section of a nerve, usually produces a permanent block. Neurolytic block, 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. ![]() 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. Nerve block or regional nerve blockade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief.
