Abstract:
Fibrin glue has been widely used for controlling hemorrhage and sealing tissue in surgery. This study was divided into 2 parts. Part 1 determined the effect of the estrous cycle on fibrinogen levels in ewes. Blood samples were collected either from estrus or from diestrus ewes (n=10) in order to compare the fibrinogen levels. There was no statistically significant difference of fibrinogen levels in the estrus and diestrus ewes (p>0.05). Therefore, fibrin glue could be prepared from sheep at any stages of cycle. Part 2 evaluated hemostatic efficacy of sheep-derived fibrin glue in pigs (n=6). Blood clotting time on a glass slide in control and treatment groups was started at 201.10±90.47 and 4.43±3.73 seconds, and was completed at 447.83±63.77 and 31.93±4.28 seconds, respectively. Bleeding quantities by mean of weight, which was estimated by the increment of filter paper weight after blood absorption from biopsy sites, were 0.94±0.38 and 0.10±0.12 g and bleeding times were 175.18±11.80 and 68.08±28.84 seconds during liver biopsy in control and treatment groups, respectively. Whole blood clotting time in vitro, bleeding quantity, and bleeding time during liver biopsy in the treatment group were significantly less than those of the control group (p< 0.01). In conclusion, sheep - derived fibrin glue is an effective hemostatic agent for controlling hemorrhage during liver biopsy in swine.
