[Liver blood flow during xenon anesthesia in surgical hepatology]

The authors present their experience gained in anesthesias for resection of the liver. Methods for evaluating total liver blood flow by ueveredine dilution, portal blood flow by thermodilution, changes in arterial blood supply during and after the operation are discussed. Effects of methods of anesthesia on total liver blood flow and some parameters of systemic hemodynamics are analyzed. Effects of neuroleptanalgesia, ketamine and xenon anesthesia on liver blood flow are compared. The efficiencies of anesthesias for resection of the liver and their effects on liver function during and after the operation are evaluated. The results evidence that disorders in liver circulation parameters were far less pronounced in the patients operated on under Xe anesthesia in comparison with patients operated on under neuroleptanalgesia and calypsol anesthesia. The study confirmed a pronounced analgesic effect of xenon, and clinical results confirmed that Xe anesthesia can be used in traumatic interventions.
