A spinal morphine pump is a microcomputerized drug delivery system the size of a teacup lid that is placed under the skin in the lower abdomen. The medication is added to the pump like a buttock injection and is refilled about once every six months. Drugs are inserted into the spinal canal through a tiny tube through the lumbar injection, automatically pumped into the oral analgesic amount of one-third of the amount of up to a good systemic analgesia, but also in the drug with some trace local anesthetic to relieve myocardial spasm, greatly reducing the systemic side effects of the drug. There is another very suitable method of analgesia for neuralgia is to puncture into an electrode in the spinal canal at the upper end of the injured spinal cord area, and bury an electric pulse generator like a cigarette lighter under the skin, and the incoming pulse regulates the process of neuralgia signals from the injury to the brain to achieve analgesia, and it can be very good to reduce or discontinue the use of neuralgia medication. These techniques are slightly more complex, but they are both injectable and subcutaneous, and are commonly done for analgesia in the U.S. A pain center can do more than 100 cases a month.
