Effect of HSRP1 oxygen-carrying solution on early perfusion in rabbits with controlled severe hemorrhagic anemia
Journal Title: Chinese Journal of Blood Transfusion - Year 2022, Vol 35, Issue 9
Abstract
Objective To observe the effect of glutaraldehyde polymerized bovine hemoglobin injection (code: HSRP1) oxygen-carrying fluid on early perfusion of severe hemorrhagic anemia in rabbits. Methods The rabbit model of controlled severe hemorrhagic anemia was established. Twelve modeled rabbits were divided into glutaraldehyde polymerized bovine hemoglobin injection (code: HSRP1) group and sodium lactate ringer′s injection (LR) group, with 6 rabbits in each group(half male and half female). HSPR1 group and LR group were treated with HSRP1 and LR, respectively. The survival rate of experimental rabbits was observed, and the indexes of hemodynamics, venous blood gas, plasma hemoglobin, base surplus, lactic acid and bicarbonate were measured before and after blood loss, as well as each point within 24 h after infusion. Results The survival rate of HSRP1 group was significantly different from that of LR group (P<0.05); After exsanguination, the mean arterial pressure of each group was significantly different from that before exsanguination (P<0.05), but there was no significant difference between HSPR1 group and LR group after infusion; In the second stage of perfusion, the blood lactate concentration and base excess in the HSRP1 group were significantly different from those in the LR group at each time point (P<0.05), at 2 h after perfusion, the respiratory rate started to differ significantly from that of the LR group (P<0.05), heart rate was significantly different from LR group at 4 h after perfusion(P<0.05); There were no significant differences between HSRP1 group and LR group in plasma venous oxygen partial pressure, venous oxygen saturation and plasma hemoglobin at all time points. Conclusion HSPR1 is used for severe traumatic hemorrhagic shock in rabbits, and can improve the survival rate of experimental rabbits by providing oxygen to hypoxic tissues and correcting anaerobic metabolism. As a new oxygen-carrying fluid, HSPR1 can correct the oxygen supply balance of patients with severe hemorrhagicanemia in early stage.
