Abstract/OtherAbstract:
This study was designed to clarify the effect of hyperdynamic circulatory support with dobutamine or dopamine after massive hepatectomy on hepatic hemodynamics, oxygen supply and demand, and lactate uptake. Mongrel dogs were allocated three groups: 70% hepatectomy group; a group that received dobutamine after 70% hepatectomy; and a group that received dopamine after 70% hepatectomy. Hepatic blood flow and oxygen delivery to the liver decreased after 70% hepatectomy. Although oxygen consumption in the liver also decreased, oxygen consumption per liver weight increased after massive hepatectomy; an increase of oxygen uptake ratio and a decrease of lactate uptake in the liver were observed. When dobutamine or dopamine were administered after 70% hepatectomy, hepatic blood flow increased, followed by normalization of the balance of oxygen supply and demand in the liver; lactate uptake subsequently improved in the liver. The data support the conclusion that hepatic oxygen consumption affected by dopamine and dobutamine is associated with an increase in the extraction of lactate. Hyperdynamic hepatic circulatory support was advantageous to hemodynamics and metabolism in the residual liver after massive hepatectomy.
