RESUMEN
Management of pain in surgical patient is very crucial. It is more so in thoracic and upper abdominal surgery. Lots of technique and drugs have been used to control postoperative pain including thoracic epidural analgesia. We describe a case in whom Intraoperative and Postoperative pain was managed by injecting 0.5% bupivacaine 20 ml in the interpleural space through the catheter, followed by continuous infusion of 0.1% bupivacaine 10 ml/ hour for 24 hours. The whole perioperative and postoperative period was uneventful. The first series of patients in whom this technique was used was described by Murphy in 1983, (1) who used it in patients with multiple fractured ribs and in postoperative patients after gallbladder and kidney surgery. One year later, Reiestad and Kvalheim published their results of continuous intercostal nerve block for postoperative pain relief and presented their modification of the technique, which is now termed interpleural analgesia.
