Voluven (hydroxyethyl starch [HES] 130/0.4), a new generation of HES product with low molecular weight, has been widely used for the treatment of traumatic and hemorrhagic shock in clinics. However, no data are available whether it affects the balance of cerebral oxygen supply and consumption when applied to resuscitate hemorrhagic shock. The purpose of this study was to address this question in rabbits subjected to a severe hemorrhagic shock.


In New Zealand rabbits, an acute hemorrhagic shock was induced by withdrawing 45% to 50% of total blood volume from the femoral vein in 10 minutes when the mean arterial pressure was reduced to 60% of the baseline level. Thirty minutes after the hemorrhage, animals were infused with either an equal amount of Voluven (group V) or a tripled amount of lactated Ringer's solution (group R). The saturation of oxygen was obtained in arterial (Sao2) and venous (SjvO2) blood samples from the femoral artery and jugular bulb, respectively. Arterial oxygen content (Cao2), jugular oxygen content (CjvO2), arteriovenous oxygen difference (AVDO2), and cerebral oxygen extraction rate (CERO2) were calculated accordingly to evaluate the oxygenation state in the brain.


Levels of SjvO2 and CjvO2 were decreased after hemorrhagic shock, and there were increases in AVDO2 and CERO2 values. After resuscitation, the SjvO2, AVDO2, and CERO2 levels in group V were quickly recovered to the basal levels, whereas the values in group R remained in the abnormal levels (p < 0.05). There were significant differences between the groups in their SjvO2 and CERO2 levels at 30 minutes after resuscitation. In addition, the mean arterial pressure was restored to the basal levels in group V but not in group R after resuscitation (p < 0.05).


We conclude that early infusion of Voluven is beneficial for maintenance of the hemodynamic stability and for the balance of cerebral oxygen supply and consumption during the resuscitation of acute hemorrhagic shock.
