Fig. 5. Time course of hemoglobin (Hb) concentration: hemoglobin was determined before (baseline [BL]; arrow ) and 5, 20, 40, 60, 120, 240, 360, 480, 720, 960, and 1,200 min after the end of the colloid infusion. Results are shown as mean (SD). * Solution effect of carboxymethylated hydroxyethyl starch (CM-HES) versus hydroxyethyl starch (HES) (Psol CM-HES) and carboxymethyl starch (CMS) versus HES (Psol CMS) as determined by two-way analysis of variance.
