The effect of absorbable gelatin sponge on experimental microvascular anastomoses

Following a pilot study a controlled trial was carried out to assess the effect of absorbable gelatin sponge on reducing the bleeding from microvascular anastomoses of the femoral arteries and veins of rats. A model was used which approximated to the clinical situation and the bleeding time was significantly reduced in arteries and veins. There was no significant difference in patency rates or wound infection.
