title: [Influence of epidural anesthesia on postoperative nitrogen sparing in major digestive surgery].
abstract: In order to determine the role of epidural anaesthesia on protein sparing, eighteen patients undergoing major visceral surgery were randomly divided into three different groups according to the mode of anaesthesia used (general anaesthesia, epidural anaesthesia, continuous epidural anaesthesia for 24 h). These patients were intravenously fed for five days postoperatively; their nitrogen balance was studied. Compared with the "general anaesthesia" group, only the daily averages of nitrogen balance of the "continuous epidural" group were significantly better. IN order to correlate stress with nitrogen saving, the early evolution of several parameters (cortisol, glucose, prolactin) used as "stress markers" was studied : there was no evidence of any significant difference between the three groups.
