Shown are changes in hemoglobin, hematocrit and arterial blood gases between the two study groups at different time points. Within the same treatment group: *versus baseline; ^†versus HD; ^‡versus H60. Among treatments: PEG-albumin versus ^bHES. BE, base excess; HD, hemodilution; H60, end of the hemorrhage period; HES, hydroxyethyl starch; PaO₂, arterial oxygen tension; PaCO₂, arterial carbon dioxide tension; PEG-albumin, polyethylene glycol-conjugated human serum albumin; S60, end of the experiment.
