Patient-controlled analgesia is a relatively new and effective technique for patients with postoperative pain and intractable pain associated with terminal illness. However, few patients have enjoyed pain relief by this technique because of its expense. We therefore devised a new PCA system in order to provide many patients with a simple and easy method. A DIB catheter consisting of a silicon balloon reservoir, flow control part and epidural catheter are attached to a microfilter and then conected with three-way cocks. Epidural administration of the drug (bupivacaine and buprenorfine) was done by the use of three way cocks by setting two inlets for infusion. Thirty patients with severe pain from Herpes Zoster were subjected to this study to evaluate the PCA system after fundamental studies on issues such as changes in balloon pressure as powersource. VAS was utilized to judge the effectiveness of this system. A clinical study proved that this new PCA system is very effective in lefting patients control their own severe pain with ease.
