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.
After the catheter is in place, a combination of narcotic and anesthesia is administered either by a pump or by periodic injections into the epidural space. A narcotic such as fentanyl or morphine is given to replace some of the higher doses of anesthetic, like bupivacaine, chloroprocaine, or lidocaine.
