摘要: 目的 研究羧甲基壳聚糖接枝聚丙烯酸钠/乙烯基吡咯烷酮络合碘材料的止血活性。 方法 在偶氮二异丁腈引发下,以丙烯酸钠、N-乙烯基吡咯烷酮、羧甲基壳聚糖和N,N'-亚甲基双丙烯酰胺为原料制备羧甲基壳聚糖接枝聚丙烯酸钠/乙烯基吡咯烷酮。然后与碘络合生成羧甲基壳聚糖接枝聚丙烯酸钠/乙烯基吡咯烷酮络合碘材料,同时进行止血活性测试。 结果 合成的材料具有很强的吸水性能,平均吸水倍率为103 g/g,并且具有很好的耳静脉和股静脉止血效果。 结论 合成材料的止血效果优于止血海绵和Quikclot。Abstract: Objective To study the hemostasis activity of iodine complex with carboxymethyl chitosan. Methods The polymers were prepared with azodiisobutyronitrile as the initiating agent and sodium acrylate, N-vinylpyrrolidone, carboxymethyl chitosan and N,N'-methylene diacrylamide as the raw materials. It was then complexed with iodine to generate iodine complex with carboxymethyl chitosan, and the hemostasis activity was tested at the same time. Results The polymers could absorb water with the value of 103g/g and showed potent hemostasis activity for auricular veins and femoral veins. Conclusion The results showed that hemostatic effect of polymers was better than that of hemostatic sponge and Quikclot.
