ABSTRACT
Objective To investigate the hemostatic property of calcium alginate (CA) sponge and its degree of safety on exterior use. Methods The optimal coagulation concentration of CA was determined by Lee-White clotting test, and then the CA was freeze-dried to form a sponge. The coagulation effect in vitro of the CA sponge was determined by Blood Clotting Index (BCI) test. The ear artery bleeding model and full-thickness skin wound model of rabbit were employed to determine the hemostatic property of CA sponge. The degree of safety of CA sponge was evaluated by cell toxicity test. Results The BCI was significantly decreased in CA sponge group (33.08±4.02) than that in gelatin sponge (72.05±10.48, P0.05), though they were all shorter significantly than that in hospital gauze group (101.00±14.71s, P<0.05). The cell toxicity of 100% CA sponge was level 1, and it complied with the safety requirements for biomaterials. Conclusion The CA sponge has a good hemostatic property without obvious cytotoxicity.
