Background/Aims: In experimental portal hypertension, blood hemoglobin levels have been shown to influence the hyperdynamic circulatory state. The aim of this study was to assess the hemodynamic effects of increasing hemoglobin concentration in human portal hypertension.Methods: Sixteen cirrhotic patients recovering from a variceal bleeding episode were randomly assigned to receive two units of packed...
