RESUMEN
The purpose of this study is to evaluate the efficacy of interpleural bupivacaine in relieving post-operative pain after thoracotomy and to report any side effects for this technique. Thirty patients who have undergone thoracotomy for different causes were studied. All patients received 20 ml bupivacaine without adrenaline, once they reported pain after surgery. The local anesthetic was administered through the chest tube. Assessment of pain in the first 30 minutes. The analgesic time was 7.8 + 2.7 hours [mean + S.D.]. No significant changes in arterial blood pressure, heart rate and respiratory rate were observed after administration of interpleural bupivacaine. There was a significant improvement in the tidal volume, PaO2 and PaCO2 after interpleural administration of bupivacaine, no side effects were observed. It is concluded that interpleural local anesthetic is a safe, simple and effective method for relieving post-operative pain after thoracotomy

One hundred fit female patients undergoing day case, gynaecological operations, in Kasr El Eini and Heliopolis hospitals were divided into two groups. All patients received 0.2 mg. "Rubinol" as a premedication, the first group received propofol 2.5mg./kg., while the second received thiopentone 4 mg/kg. Increments of both drugs were given if needed. Maintenance of anaesthesia with NO2/O2 via face mask. Pulse, blood pressure and ECG were monitored. Induction time, side effect and recovery time were observed. In propofol group-pain on injection, apnoea and drop of the blood pressure showed a higher incidence than in thiopentone group, excitatory movement, cough, hiccup, laryngeal spasm, nausea and vomiting were completely absent in propofol group. Recovery times were significantly shorter after propofol. This finding together with the quality of anaesthesia make propofol preferable and specially for day case surgery
