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.
General anesthesia is, essentially, a medically induced coma, not sleep. Drugs render a patient unresponsive and unconscious. General anesthetics are normally administered intravenously (IV) or inhaled. Under general anesthesia, the patient is unable to feel pain and may also have amnesia. The drugs will be administered by an anesthesiologist, a specially trained doctor who will also monitor a patient's vital signs and rate of breathing during the procedure.
