Abstract | BACKGROUND: METHODS: Sixty-three patients scheduled for major abdominal surgery were analyzed retrospectively. Patients were classified into three groups by age; under 65 years of age (Group 1, n = 23) ; 65-75 years (Group 2, n = 30); over 75 years (Group 3, n = 10). Anesthesia was induced with propofol and was maintained with isoflurane- nitrous oxide inhalation. All patients received 30-45 mg of pentazocine before incision. At the end of surgery, subcutaneous pentazocine PCA was begun at a rate of 0.5 ml x hr(-1). Given regimen was pentazocine 240-390 mg and droperidol 5 mg with 1% lidocaine, and the total amount of dose was 40 ml. Postoperative pain control was assessed using a 5 rating verbal pain score (VPS) and a visual analog pain scale (VAS). RESULTS: Subcutaneous PCA of pentazocine provided adequate analgesia over 70% of the patients studied. There were no differences between the three groups regarding VPS and VAS. There are no severe complications. CONCLUSIONS: Subcutaneous PCA of pentazocine is a simple, safe, and effective method to control postoperative pain after major abdominal surgery. Effectiveness of subcutaneous PCA of pentazocine did not depend on age of patients.
