neurolytic block

neurolytic block

Pain management A form of anesthesia in which a neurodestructive agent–eg, phenol and alcohol is injected at or near a nerve causing extreme pain; NBs are useful in cancer pain syndromes that are visceral or involve the torso, but rarely for pain of extremities, as it would cause paralysis.
