Surgical Investigation of a New Absorbable Sponge Derived from Gelatin for Use in Hemostasis

Abstract
57 exptl. intracranial implantations in 56 monkeys and use of the material in 24 routine neurosurgical operations are reported. Little more tissue reaction than that formed in response to simple blood clots was observed. Pieces of sponge disappear from 20-45 days after operation. It seemed to make no difference whether bovine or human thrombin was used to impregnate the sponge. Use of the sponge to repair torn vessels is not attended by intravascular thrombosis.
