THE USEFULNESS OF CONTINUOUS SUBCUTANEOUS INFUSION USING THE PATIENT CONTROLLED ANALGESIA SYSTEM IN THE POSTOPERATIVE PAIN CONTROL

Abstract

In this study the usefulness of the postoperative pain control was comparatively studied in 135 patients undergoing an abdominal surgery at the hospital by dividing into three groups: 1) 90 patients received continuous subcutaneous infusion of buprenorphine; 2) 20 patients received continuous subcutane-ous infusion of buprenorphine using the patient controlled analgesia (PCA) system; and 3) 20 patients received continuous subcutanoeous infusion of pentazocine using the PCA system.
As a result, continuous subcutaneous infusion of buprenorphine was effective in the postoperative pain control, and a use of the PCA system might contribute to the safety personal saving in the medical care. However, it poses a further problem that buprenophine can cause adverse effects such as dizziness and nausea in about 10% of the patients. Continuous subcutaneous infusion or pentazocin was significantly inferior to that of buprenorphine in the analgesic effect and has a problem in the safety.
