ABSTRACT
A porous composite particle (CP) was fabricated by the methods of emulsification and cross-link based on chitosan, alginate and collagen protein, and the tranexamic acid-loaded composite particles (TACP) was prepared by immersing the composite particle into the solution of tranexamic acid and by freeze drying. In the hepatic and splenic hemorrhage model of rabbits, CP and TACP were randomly used as haemostatic agents, and the Suxiaozhixuefen (Flashclot) was used as control. The corresponding hemostatic time and bleeding amount were observed respectively. The hemostatic time of CP and Flashclot were (2.48 +/- 0.88) min and (3.07 +/- 0.84) min, respectively, no significant difference was observed. However, the hemostatic time of TACP was (1.90 +/- 0.75) min, which was significantly shorter than that of CP and Flashclot (P < 0.05). In the splenic bleeding model of rabbits, similar results were obtained with these three kinds of hemostatics. These results indicated that the CP based on chitosan, alginate and collagen protein displayed similar hemostatic efficiency to Flashclot. However, the TACP might be one of promising haemostatic powders due to its more excellent hemostatic efficiency.
