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 anesthesia is slightly different to an epidural in that a smaller needle is used to inject a local anesthetic drug into the spinal fluid. Spinal anesthesia is often used for emergency cesarians as the result is immediate pain relief and loss of sensation.
