Background: A phase-III trial that included
fifty-three patients undergoing unilateral primary total knee arthroplasty
with cement was conducted to investigate the hemostatic efficacy
of fibrin sealant.
Methods: Following cementing of the joint, 10 mL
of fibrin sealant was sprayed onto the wound before tourniquet deflation
and wound closure. No placebo was used in the control group. All patients
received drains.
Results: Within twelve hours after the surgery,
the amount of bloody drainage was 184.5 ± 28.9
mL (mean and standard error) in the fibrin-sealant group (information
available for twenty-three patients) and 408.3 ± 54.6
mL in the control group (information available for twenty-three
patients) (p = 0.002, after adjustment for variance in
the time that the drainage was measured). On the first postoperative
day, the hemoglobin level had decreased by 20.1 ± 2.1
g/L in the fibrin-sealant group (information available
for twenty-two patients) and by 27.3 ± 2.1
g/L in the control group (information available for twenty-four
patients). After adjustment for baseline values, the decrease in
the hemoglobin level was 28.9% less in the fibrin-sealant
group than in the control group (p = 0.005, 95% confidence
limits = 10.2, 43.7). There were no seroconversions in
the fibrin-sealant group.
Conclusion: These results suggest that fibrin sealant
can safely reduce bloody drainage following total knee arthroplasty
while maintaining higher hemoglobin levels.
