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.
A spinal anesthesia is usually provided at the lower back or the lumbar region. An epidural will be placed in the lower back in case of pelvic or lower body surgeries and in the mid back or the thoracic region for chest surgeries. A spinal involves a single injection into the spinal sac. However, if you are given an epidural, your doctor may attach a catheter to the area.
