英文摘要Biomedical materials with effective hemostatic properties are in great demand in clinical and battlefield application for severe hemorrhage control. In this study, nearly amorphous chitin is obtained by treating alpha-chitin with superfine grinding, and the solubility of chitin in hexafluoro-2-propanol (HFIP) is significantly increased. Chitin and gelatin mixtures are prepared by adding different amount of gelatin to the 8 mg mL(-1) chitin solution. In the presence water (nonsolvent), the mixtures are gelled as HFIP is replaced by water, and chitin/gelatin composite sponges with directional pore structure are prepared by directional freeze drying of the hydrogel. The structure, porosity, liquid absorbing capacity, biodegradability, and hemostatic properties of the sponges with different ratios of gelatin are investigated. The results show that the sponge with the mass ratio of chitin/gelatin of 1:1 is potential hemostatic material with high absorbing capacity, hemocompatibility, and the best hemostatic performance. The in vivo study demonstrates that hemostatic time of the composite sponge (73 s) is much shorter than of that of gauze (193 s), chitin sponge (132 s) as well as gelatin sponge (116 s) in rat femoral artery injury model.
