The Control of Postoperative Pain by Thoracic Fentanyl Epidural and its Effect Upon the Stress Response
Patients scheduled for elective upper abdominal surgery were divided into two groups. Group 1 received preoperative diazepam and a thoracic epidural catheter through which was administered 200 μg in saline. Postoperatively, epidural infusion of fentanyl (approximately 66 μg/h) was maintained. Group 2 received pre- and postoperative medication with papaveretum i.m. All patients were anaesthesized with nitrous oxide and halothane. Postoperatively, Group 1 showed low pain and sedation scores though higher nausea scores than those observed in Group 2. Postoperative respiratory function was significantly better urine output and nasogastric output was significantly greatry depression were observed.
