[Risk factors and their correction during shunt operation in children with extrahepatic portal hypertension].

Central hemodynamics, blood gas composition, portal blood flow, and hepatic function have been studied in 30 children with extrahepatic portal hypertension during various types of intraoperative anesthesia. Neuroleptanalgesia and combined halothane and calypsol anesthesia ensure an adequate patient protection from surgical trauma. Each type of anesthesia has its specific effect on portal blood flow. This type of surgical interventions is characterized by frequent use of blood transfusions. According to the data of histochemical and biochemical studies all types of anesthesia have an equal effect on the liver.
