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.
In general sedation will not require a breathing tube and is fairly easy to rebound from. General anesthesia is what is thought about for most surgeries. In this type of anesthesia, the patient is completely asleep, requires a breathing tube and can take a day or two to recover. Eyelid surgery can be done with any of the three types of anesthesia. Upper eyelid surgery is probably most commonly done using local anesthesia though there are circumstances where sedation or even general is necessary. Lower eyelid surgery is a bit more complicated.
