<unk>  or regional<unk> ade is any deliberate interruption of signals traveling along a nerve, often for the purpose of pain relief. Local anesthetic<unk>  (sometimes referred to as simply<unk> ") 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. 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. Neurectomy, the cutting through or removal of a nerve or a section of a nerve, usually produces a permanent block. 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. The concept of<unk>  sometimes includes central<unk> , which includes epidural and spinal anaesthesia.
