Effects of two different hydroxyethyl starch solutions (HES200/0.5 vs. HES130/0.4) on the expression of platelet membrane glycoprotein.

BACKGROUND

There are various hydroxyethyl starch (HES) solutions with different degrees of hydroxylation and different molecular weights. HES200/0.5 solution is most commonly used. HES130/0.4 is a new HES solution and is the 'state-of-the-art' in volume substitution. However, the mechanism of the observed anticoagulation action of HES has not been fully delineated. The objective of this study was to further investigate the effect of HES200/0.5 and HES130/0.4 on platelet coagulation.

METHODS

Sixty ASA I-II patients undergoing elective minor surgery were randomly allocated to receive an intravenous infusion (20 ml/kg) of lactated Ringer's solution (group L), HES200/0.5 (group H) or HES130/0.4 (group V) after the induction of anesthesia. The expression of CD42b, CD41/61 and CD62p in vivo was assessed on non-stimulated platelets and adenosine diphosphate (ADP) agonist-activated platelets using flow cytometry.

RESULTS

Resting glycoprotein expression of the non-stimulated platelets was observed. HES200/0.5 and HES130/0.4 reduced the CD42b, CD41/61 and CD62p expression of ADP-agonist-activated platelets at 15 min after intravenous infusion. At 6 h after intravenous infusion, the trend of decreasing expression of activated CD42b, CD41/61 and CD62p was maintained in group H. However, CD42b, CD41/61 and CD62p expression returned to the pre-operative level in group V.

CONCLUSIONS

This study showed that both HES200/0.5 and HES130/0.4 can inhibit platelet coagulation. Platelet dysfunction experienced a faster recovery after the infusion of HES130/0.4 than after HES200/0.5. Liquid resuscitation with HES130/0.4 may decrease the risk of hemorrhage in the operative period.
