The spray application of cryo-based fibrin sealant was evaluated for reduci
ng hemorrhage in a complex, anticoagulated canine model of knee joint arthr
oplasty. Nine heparinized dogs underwent bilateral knee arthroplasty under
tourniquet control with each animal having 3 mt of fibrin sealant sprayed o
nto one joint and the other joint serving as control. The fibrin sealant si
gnificantly reduced total and incremental bleeding as compared to the contr
ol side (P < .05). In addition, the hemostatic effectiveness of the fibrin
sealant increased as bleeding propensity increased (P < .05). This study su
ggests that fibrin sealant may reduce bleeding from orthopedic joint replac
ement in human patients undergoing routine operations as well as those rece
iving forms of anticoagulation to reduce the incidence of deep venous throm
bosis and pulmonary embolus.
