OBJECTIVE： To study the hemostatic effect of porcine fibrin sealant patch （DBT） on bleeding wound of liver in rats and gluteus maximus in heparinized rabbits. METHODS： 48 rats and 24 rabbits were randomly divided into sham operation group， operation control group （gauze hemostasis）， medical collagen sponge group and DBT group. Except for sham operation group， animals in other groups were reduced for rat model with liver bleeding or heparinized rabbit model with gluteus maximus bleeding. The hemostatic time was recorded， bleeding amount was calculated； DBT degradation and wound adhesion in liver after 3， 13 weeks were observed； re-bleeding rate of heparinized rabbits in medical collagen sponge group and DBT group were investigated. RESULTS： Compared with sham operation group， the hemostatic time and bleeding amount of animals in operation control group were significantly increased （P＜0.01）. Compared with operation control group， the hemostatic time and bleeding amount of animals in DBT group and medical collagen sponge group were significantly reduced （P＜0.01）. After 3， 13 weeks， different degree of adhesion appeared in the wound of rats in each group， while the adhesion scores had no statistical significances （P＞0.05）. After 13 weeks， liver margin of rats in administration groups was slightly blunt， but it basically had been restored to preoperative state， with good healing. DBT can be degraded and absorbed completely. The re-bleeding rate of rabbits in DBT group were 33.3％， 66.7％ in medical collagen sponge group. CONCLUSIONS： DBT has good hemostatic effect on fragile organs and the body with blood coagulation dysfunction， and can be degraded and absorbed. Its effect is equivalent to medical collagen， while the adhesive strength is slightly better than the latter.
