Abstract
ObjectiveTo explore the feasibility and efficacy of continuous subcutaneous pump injection of high-dose morphine for cancer pain relief by retrospectively analyze 15 patients who had received this pain relief therapy during 2005 to 2010. Methods We inserted a catheter subcutaneously into the periumbilical tissue, calculated the total daily dose of morphine, selected a Baxter pump to continually administer morphine according to the speed of infusion. We adjusted the dosage of morphine use based on the changes in pain level. Results The total response rate for pain relief was 100%. 11 of the 15 patients(73.3%)had complete relief and the remaining 4(26.7%)had partial relief. Conclusions Continuous subcutaneous pump injection of high-dose morphine for pain relief is reliable in patients with advanced cancer and had slight side effects. It is worth popularizing.
