Cardiac function within 96 hours after hospital admission. The cardiac output and the predicted cardiac output (predicted CO) were significantly decreased in burns of >80% total body surface area (TBSA), while there was no difference between the three other burn groups. The predicted stroke volume was significantly decreased in the >80% TBSA burn group when compared with the other three groups. There were, however, no differences between groups in the heart rate, predicted heart rate, cardiac index, and central venous pressure. *Significant difference between >80% TBSA burn group versus 60–79%, 40–59% and <40% TBSA burn groups, P < 0.05.
