Abstract:
Objective To investigate the volume kinetics of 6% hydroxyethyl starch 130/0.4 in healthy volunteers.Methods Seven healthy volunteers aged 18-32 yr weighing 46-84 kg were selected in this study. 6% hydroxyethyl starch 130/0.4 30 ml/kg was infused over 60 min. Volume kinetics analysis of 6% hydroxyethyl starch 130/0.4 was performed with Matlab 6.0 software, compartment model was determined by F test.Results One-compartment model parameters: basic clearance, clearance and distribution volume of one-compartment model were (3.5 ± 1.3) ml/min,(19± 11) ml/min and (5746 ± 1371) ml respectively. Two-compartment model parameters: clearance, K1, the volume of central compartment, the volume of peripheral compartment, distribution volume of two-compartment model were (63 ±29) ml/min,(11 ±4) ml/min, (1551 ± 995) ml, (908 ±398) ml,(2460 ± 1332) ml respectively. There was no difference between the distribution volume of one-compartment model and blood volume of healthy volunteers ( P ＞ 0.05) .The distribution of infused 6% hydroxyethyl starch 130/0.4 was accordant with one-compartment model (F value was 3.81, P ＞ 0.05)and 4 h clearance was (75 ± 10)% .Conclusion The distribution of infused 6% hydroxyethyl starch 130/0.4 for volume expansion is accordant with one-compartment model, and the effective duration of plasma volume expansion is 4 h.
