Fibrin glue has been widely used for controlling hemorrhage and sealing tissue in surgery. The purpose of this study was to evaluate the hemostatic efficacy of sheep-derived fibrin glue. Six Marino sheep were used to collect concentrate fibrinogen preparation by the ammonium sulfate precipitation method. Crossbred pigs (n=6) were used to evaluate hemostatic efficacy by monitoring whole blood clotting time by the glass slide method, bleeding time and bleeding quantity during liver biopsy. Mean whole blood clotting time on a glass slide started at 201.1±90.47 and 4.43±3.73 seconds, and was completed at 447.83±63.77 and 31.93±4.28 seconds in control and treatment groups respectively. Two-sited open liver biopsies were performed, each biopsy site was assigned as either control or treatment groups. One ml of sheep-derived fibrin glue on the bleeding surface was applied at the treatment sited group. Bleeding quantity was estimated by the increased weight of filter paper after blood straining. Mean bleeding quantity was 0.94±0.38 and 0.1±0.12 g, and mean bleeding time was 175.18±11.80 and 68.08±28.84 seconds in control and treatment sites, respectively. Whole blood clotting time, bleeding time, and bleeding quantity were significantly less in the treatment-sited group, compared to the control-sited group (p<0.01). In conclusion sheep-derived fibrin glue could be applied as an effective hemostatic agent to control hemorrhage after liver biopsy in swine.
