[Hemodynamic disorders in liver transplantation and their correction].
To study the pre- and intraoperative causes of hemodynamic disorders at the basic stages of liver transplantation in adult recipients, case histories and anesthesia protocols were analyzed in detail in 15 recipients of the cadaveric liver (Group 1) and 60 recipients of a liver portion taken from a living relative donor (Group 2). The patients' preoperative status, the etiology of the disease, the pattern and scope of preoperative preparation and examination, the cause of anesthesia, the volume, pattern, and rate of infusion were studied. Particular emphasis was placed on the presence of pathophysiological prerequisites and various intraoperative factors, which are causes of hemodynamic disorders. Orthotopic transplantation of the liver was performed under generalized balanced anesthesia whose major components were the inhalational anesthetics isoflurane and sevoflurane (89.3%) or total intravenous anesthesia based on neuroleptic anesthetics (10.7%). The main causes of hemodynamic disorders were the patients' severe baseline condition, anemia, ascitis, intoxication, encephalopathy, and the specific features of a surgical intervention, blood loss, heavy plasma and perspiration losses, water-electrolyte balance impairments, vein-vein shunt and reperfusion syndrome. Operations of extraordinary duration (longer than 15-20 hours) required higher plasma compensation volumes (36-52 ml/kg). Severest hemodynamic disorders were observed in patients admitted to hospital for emergency transplantation of the cadaveric liver. These patients who are to undergo transplantation are outside hospital in most cases, which is why any operation should be regarded in them as an emergency one made in patients who are in a very severe state (ASA IV-VE).
