ABSTRACT

BACKGROUND:

Hydroxyethyl starches (HES) solutions are the most commonly used colloids for treating hypovolemia and expanding plasma, but they compromise platelet function and reduce the level of coagulation factors. As opposed to other HES solutions, 6% HES (130/0.4) solution may influence hemostasis minimally due to its low mean molecular weight and degree of substitution. This study was designed to establish the safety of HES (130/0.4) infusion in the presence of massive blood loss.

METHODS:

Twelve healthy adult patients scheduled for spine surgery were enrolled in this study. Before the induction of general anesthesia, all patients underwent acute normovolemic hemodilution (ANH), which was independent of surgical stress and other confounding factors. While approximately 30% of the estimated blood volume was procured, the blood deficit was replaced with the same volume of 6% HES (130/0.4) solution. Hematocrit, platelet count, factor VIII activity and plasma fibrinogen concentration were determined and thrombelastography was performed to evaluate the hemodilution effect and hemostatic impairment before and after ANH. Statistical testing was conducted to analyze the effect of HES on hemostasis.

RESULTS:

Hematocrit, platelet count, factor VIII activity and plasma fibrinogen concentrations decreased significantly (P < 0.05 respectively) after the ANH. On comparing pre-ANH and post-ANH thrombelastographic findings, the R time was shortened (P = 0.045), the alpha angle increased (P = 0.01) and MA decreased (P = 0.003) significantly.

CONCLUSIONS:

Summarizing, little effect was observed on the hemostatic system when 20 ml/kg of 6% HES (130/0.4) solution was infused. HES (130/0.4) solution as used to maintain normovolemia during ANH may be free from bleeding risk.
