In this study, changes of SHD and oxygen transport and consumption (OTC) during the anhepatic phase used the passive bypass (PB) with Anthron🄬 bypass tubes were compared with those used the pump-driven bypass (PDB) with a centrifugal pump in mongrel dogs. Moreover the effects of the increased instillation rate and administration of dobutamine on SHD and OTC were evaluated.
The portal venous and inferior vena caval pressure were increased in PB group, but not in PDB group. Whenever PB or PDB was used, cardiac index and oxygen consumption were markedly decreased caused by hypovolemia.
In PDB group trebled the instillation rate, SHD and oxygen consumption were not improved. These results suggested that the primarily cardiovascular depression during the anhepatic phase was related to the disturbans of SHD.
When dobutamine was administrated and the instillation rate was trebled in PDB group, SHD and OTC were maintained in a favorable state.
It is concluded that PDB, administration of dobutamine and sufficient instillation are advantageous to maintain systemic hemodynamic stability during the anhepatic phase of orthotopic liver transplantion.
