Abstract

This study was undertaken to evaluate the response to therapy aimed at achieving supranormal cardiac and oxygen transport variables (cardiac index > than 4.5 L/min/m2, oxygen delivery > 600 ml/min/m2, and oxygen consumption > 170 ml/min/m2) in patients with cirrhosis who have undergone partial hepatectomy and to assess the relationship between those parameters and outcome. Thirty-four consecutive patients underwent elective hepatectomy for hepatocellular carcinoma. The postoperative outcomes and hemodynamic and oxygen transport values in 16 patients (group S) who maintained supranormal values were compared with those in 18 patients (group N) treated to maintain normal hemodynamic values. Patients in group S received volume expansion and then, if necessary, dobutamine (3 to 15 micrograms/kg/min) to increase cardiac index, oxygen delivery, and oxygen comsumption simultaneously during the first 12 hours. The hemodynamic targets were reached by 56% of patients in group S during the first 12 hours and 31% during the next 12 hours. Postoperative blood lactate levels at 12 and 24 hours were lower in group S than in group N, and total bilirubin concentrations, hepatic venous oxygen saturation, and arterial ketone body ratio, useful mar...Continue Reading
