Spinal anaesthesia. Spinal anaesthesia (or spinal anesthesia), also called spinal block, subarachnoid block, intradural block and intrathecal block, is a form of regional anaesthesia involving the injection of a local anaesthetic into the subarachnoid space, generally through a fine needle, usually 9 cm (3.5 in) long.
Spinal and epidural anesthesia fall into the category of 'neuraxial anesthesia'. Neuraxial refers to the spinal column and related structures. Broadly, epidurals and spinals may be categorized as 'regional anesthetics', as well, since they do numb a region of the body by targeting nerves that supply that area.
