INTRODUCTION: Personal experience in the treatment of postoperative pain using intrapleural analgesia applied on 50 patients chosen at random in a group of 90 after thoracotomy is reported. METHODS: At the end of operation a peridural catheter for continuative infusion was applied in the paravertebral socket by direct transfixion of chest wall. A local anaesthetic has been given (75 mg of bupivacaine 0.50%) through the catheter at 8 hours interval for three times at the most. The degree of analgesia has been valued immediately before and after medicine administration and during the 8 hours interval by recording the cardiocirculatory and haemogasanalytical parameters. The measurement of pain intensity has been achieved by visual analogous just an hour after operation and subsequently every 4 hours during the first post operative day and every 8 hours during the following days. RESULTS: Most of the examined patients (90%), reported a remarkable attenuation of pain, valued by achromatic grey test after 4 hours since the first giving. The catheter has always been removed during the 8th postoperative day and it did not cause intrapleural complications. The method used warrants a good level of analgesia, improving the respiratory per-formance and giving a rapid mobilization, essential items in the reduction of immediate post operative complications. CONCLUSIONS: The results confirm the validity of this treatment in the pain control of thoracothomized patients with a positive answer in 45 out of 50 examined patients without remarkable complications.
