Alcohol is a flammable liquid and should be kept cool and away from any heat source. Alcohol injections should be made with care to avoid unwanted tissue necrosis. Proper positioning of the patient is essential to control localization of injections of dehydrated alcohol (which is hypobaric) into the subarachnoid space.
The most commonly encountered side effects are post-injection neuritis with persistent pain, hyperesthesia and paresthesia. Subarachnoid neurolysis and lumbar sympathetic block may be followed by motor paralysis, bladder or rectal incontinence and impotence. Severe hypotension may follow celiac ganglion injection. Corneal anesthesia, meningitis or cranial nerve palsy may follow injection of the gasserian ganglion.
