[Propofol and thoracic surgery].
20 patients undergoing thoracic surgery were studied. Before anaesthesia either a catheter was placed in the intercostal space, at the same level as the thoracotomy (16 patients) or an epidural catheter was inserted if there was a contraindication of intercostal blockade (4 patients). Marcaine 0.5--was injected. Anaesthesia was induced with propofol 2.5 mg.kg-1, vecuronium 0.1 mg.kg-1, dextromoramide 50 mcg.kg-1. It was maintained with propofol 9 mg.kg-1.h-1 for 30 mn, then 4.5 mg.kg-1.h-1 for following hours (by a syringe pump) and vecuronium 0.1 mg.kg-1.h-1. Cardio vascular effects were studied only in the 16 patients with intercostal blockade: during induction bradycardia in 3 patients, and systolic arterial pressure (S.A.P.) decrease of 30% in 8 patients were observed. After the incision, heart rate and S.A.P. became steady. The average duration of anaesthesia was 214 min +/- 74. The time from the end of propofol infusion to the moment of extubation was 15.4 min +/- 33 and the time to recover all mental faculties was 46 mn +/- 11. 30 min after the end of anaesthesia the maxima minute ventilation was equal to the post operative value at 48 H. Propofol anaesthesia allows a fast awakening, without cumulative effects.
