Talk about some personal views on morphine pump implantation, 1, implantation timing: if the cancer has been incurable, pain is inevitable, then as soon as possible, the most effective way to achieve maximum pain improvement, rather than as a terminal helpless choice, before already suffering from pain, spend a lot of money. 2, so expensive treatment can be effective: pre-test injection, the first single intrathecal injection of morphine, observation of the degree of pain relief, analgesics to reduce the dose and the degree of improvement in physical activity to determine the effectiveness of intrathecal drug delivery, patient satisfaction is the most important determining factor, our patients did a pre-test basically chose to implant a morphine pump because of the improvement of this pain, quality of life is the improvement of the conservative treatment is difficult to achieve the effect. treatment was difficult to achieve. Moreover, this pre-test is easy to perform, inexpensive, and can be completed in a few minutes. 3, trauma can bear: two incisions, the depth of only subcutaneous fascial layer, the length of about 3, 6 cm, trauma is very small, physiological interference is slight. 4, easy to carry? All the equipment is buried under the skin, no accessories outside the body after healing. 5.Is it affecting other examinations and treatments in the future? No conflict. 6.Comprehensive cost: morphine pump expensive upfront, but later basically no maintenance, only need to add drugs regularly, the interval of several months or even nearly a year before the need to add drugs once, each time the cost of about one thousand dollars, the total calculation, and will not exceed the conservative treatment too much, with the application of the time to extend, and even lower than the cost of conservative treatment.
