Absorbable chitosan (Cs)/starch (St) powder offers a wide range of attractive benefits such as biocompatibility, easy handling, blood coagulability. In this study, we fabricated to use as a powder-type absorbable hemostatic agent such as CaCl2 and thrombin. The crosslinked structure and morphology were determined using FTIR and SEM. In vitro whole blood coagulation experiment showed rapid blood coagulation within one minutes after introduction with fabricated powder-type hemostatic because of absorption by providing calcium ion and thrombin. In vivo studies using haemorrhaging liver rat model showed that the Cs/St/CaCl2/thrombin group reduced bleeding time and hemorrhage quantity than control and commercial products groups. The Powder-type Cs/St/CaCl2/thrombin hemostatics has excellent hemostatic activity and biocompatibility properties for use in clinical hemostasis applications.
