Implantable programmable morphine pump technology is one of the ultimate methods to treat cancer pain and chronic refractory pain in the international pain community in recent years. It has the miraculous effect of immediate treatment on the pain that can not be relieved by many other analgesic methods. Implantable programmable morphine pump technology that is under the guidance of the C-arm X-ray fluoroscopy, the lumbar puncture, a special catheter placed in the subarachnoid space, and then implanted in the patient's skin with a programmable morphine pump, using Subcutaneous tunnel way to connect the catheter and pump. The pump has a reservoir to store morphine liquid, the pump infusion system can be liquid through the catheter slowly and evenly into the subarachnoid cerebrospinal fluid. Since morphine acts directly on the endorphin receptors in the spinal cord and brain, traces of morphine achieve satisfactory analgesia and reduce the side effects of systemic morphine. According to research reports, to achieve the same analgesic effect, oral and subarachnoid drug ratio of 300: 1. Drug reservoir can be repeated injection, and can change the concentration of liquid. Can also be based on the condition needed in the case of no surgery, remote control of morphine pump infusion rate. Implantable programmable morphine pump treatment of cancer pain and chronic intractable pain in Europe and the United States and other countries have been widely carried out and achieved convincing results. The biggest advantage of this method is safety, less trauma, significant effect, simple operation, patient tolerability, fewer complications, to adapt to all by other traditional methods of treatment and drug therapy ineffective or intolerant drug treatment side effects of cancer Pain and chronic refractory pain patients, and a high success rate.
