Continuous epidural analgesia with morphine via portable infusor(Baxter Infusor, BI) is a good technique for the management of intractable cancer pain. The method of subcutaneous tunnelling with portable infusor has been widely used for the cancer pain management. We examined the doses of morphine, duration of subcutaneous tunnelling, side effects, age distribution and causes of pain. The mean initial dose of morphine was 6.09 and the last 24.02 mg. Mean duration of subcutaneous tunnelling was 53.71 days and voiding difficulty, pruritus, respiratory depression were observed. Most of the patients were at the ages of 6th decade and the most common cause of pain was stomach cancer. It is suggested that the management of intractable cancer pain with epidural morphine through subcutaneous tunnelling via portable infusor is satisfactory and reliable.
