Shown are the changes in MAP and HR between the two study groups at different time points. Baseline: MAP (mmHg) = 107.4 ± 8.2, HR (beats/minute) = 466.3 ± 24.2. Within the same treatment group: *versus baseline; versus hemodilution. Among treatments: PEG-albumin versus bHES. HD, hemodilution; H0, beginning of hemorrhage; H30, midpoint in the hemorrhage period when most of the 60% volume has been withdrawn; H60, end of the hemorrhage period; HES, hydroxyethyl starch; HR, heart rate; MAP, mean arterial pressure; PEG-albumin, polyethylene glycol-conjugated human serum albumin; S30, 30 minutes after beginning of shock; S60, end of the experiment.
