目的 对复凝粉的止血作用进行比较实验研究 ,为进一步研制快速止血急救装备提供可靠依据。方法 以家兔为实验对象 ,实验分为 6组 :空白对照组、阳性对照组、海螵蛸粉组、凹凸棒石粉组、复凝粉组Ⅰ、复凝粉组Ⅱ。实验内容包括 :①体外凝血时间的测定 ,②家兔创伤模型的建立及止血实验等。结果 复凝粉组Ⅰ和复凝粉组Ⅱ结果相似 ,体外凝血时间与其它各组相比有显著性差异 (P <0 .0 1) ,止血实验效果显著。结论 复凝粉组在本实验条件下止血效果明显优于其它各组。
Objective To comparatively study the hemostatic effect of complex coagulant powder and provide a reliable basis for the further development of rapid hemostatic emergency equipment. Methods The rabbits were divided into 6 groups: control group, positive control group, sea buckthorn powder group, attapulgite powder group, complex coagulation powder group Ⅰ, complex coagulation powder group Ⅱ. The experimental contents include: ① determination of clotting time in vitro, ② establishment of rabbit trauma model and hemostasis experiments. Results The results of complex coagulation powder group Ⅰ and complex coagulation powder group Ⅱ were similar. The coagulation time in vitro was significantly different from other groups (P <0.01), and the effect of hemostasis was significant. Conclusion The coagulation powder group has better hemostatic effect under the experimental conditions than other groups.
