Objective: To compare the colloids 5% albumin, 4% gelatin and 6% hydroxyethyl starch (HES) 130/0.4 with each other and with saline, regarding their plasma-expanding effects after haemorrhage; these were also compared with the intravascular volume-expanding effect of re-transfusion with erythrocytes. Design: Controlled, prospective, randomised laboratory study. Setting: University research laboratory. Subjects: Thirty-five adult rats. Interventions: Plasma volume was determined (I(125) albumin tracer technique) after haemorrhage of 20 ml/kg and 3 h after a bolus infusion of 20 ml/kg of each of the colloids or 80 ml/kg of saline, or 6.7 ml/kg of erythrocytes diluted in 9 ml/kg of saline. Blood pressure, haematocrit (Hct), blood gases and physiological parameters were measured. Measurements and Results: Plasma volume after haemorrhage was 29.6+/-2.6 ml/kg (n=35). With the bolus infusion, plasma volume increased by 21.1+/-3.6 ml/kg in the albumin group (n=7), by 13.1+/-2.9 ml/kg in the gelatin group (n=7), by 13.8+/-2.2 ml/kg in the HES group (n=7), by 16.0+/-2.4 ml/kg in the saline group (n=7) and by 6.9+/-2.3 ml/kg in the erythrocyte group (n=7) 3 h after the infusion. In the latter group, there was a total increase in intravascular volume of 13.6+/-2.5 ml/kg including the erythrocyte volume. Arterial pressure was better preserved in the albumin and erythrocyte groups than in the other groups. Conclusion: Albumin 5% was a more effective plasma volume expander than gelatin and HES. Saline, with a four times larger volume, and erythrocytes in about 1/3 of the volume had a similar volume-expanding effect to gelatin and HES. [ABSTRACT FROM AUTHOR]
