Abstract:
Objective To investigate the effects of resuscitation with limited fluid on rabbits with uncon-trolled hemordaagic shock. Method Uncontrolled hemorrhagic shock was produced in 40 rabbits. When the mean arterial pressure dropped to 40 manI-Ig and maintained for 30 minutes, resuscitation was initiated with Ringer solu-tion infusion into rabbits in large volume for group N3 (125 mL/kg) ,moderate volume for group N2 (92 mL/kg) and small amount for group N1 (57 mL/kg), and a drop of fluid was not given to rabbits of group N4. Besides, rob-bits of group N5 were controls without shock. MAP, fatality, volume of blood loss, SOD and Her were observed for 120 minutes or until death. Data were analyzed using SNK-q test and rank test. Results MAP, SOD and Het were higher, and fatality and blood loss were lower in group N5 than those in groups N1, N2,and N3 (P<0.01 ). MAP,fatality,blood loss and Het of group N4 were worse than those of groups N1,N2 and N3 (P<0.01). The blood loss and fatality in group N3 were significantly higher than those in groups N1 and N2 (P<0.01 ). SOD of kidney in group N3 was significantly lower than that in group N1 and N2(P<0.01). As the volume of fluid in-creased during resuscitation, Het of all animals was gradually becoming lower. As MAPS in groups N2, N3 and N4 were gradually becoming lower and lower, death increased. Conclusions Limited fluid resuscitation (57～92mL/kg) should be recommended to the therapeutic strategy for uncontrolled hemorrhagic shock.
