To study whether an implanted epidural catheter and drug infusion system improve patients' QOL, we used this device for 18 patients. An implanted epidural catheter inserted by paramedian approach through the subcutaneous tunnel was connected to the external ambulatory infusion pump system. Epidural morphine, 4mg/day, through this delivery system provided excellent pain relief in patients suffering intractable pain and not responding to oral analgesic.
A technique for the insertion of an implanted drug system is easy, a less invasive procedure, and this system is much less expensive in comparison with the system, formerly used.
This method of delivery systems can be used in home health care programs as well as in outpatient clinic.
