title: Effect of thrombin-induced hemostasis on the efficacy of an absorbable adhesion barrier.
abstract: Serosal injury, bleeding and fibrin deposition are major factors in the development of surgical adhesions; meticulous hemostasis is desirable but not always achievable. The effects of thrombin on adhesion formation and the performance of Interceed Barrier were tested in separate series using a standard model and two levels of bleeding: an "oozing" model in which rabbit uterine horns were scraped to produce uncontrolled punctate bleeding and a "bleeding" model, in which four small blood vessels nicked on the ligament to each horn produced heavier bleeding. Substantial clots in the bleeding model were not removed. Adhesions, assessed after two weeks, were not worsened by the use of thrombin to control bleeding. While Interceed Barrier alone did not reduce adhesions at sites of bleeding, achieving hemostasis with thrombin and then applying Interceed Barrier significantly reduced adhesions. The effect was not achieved by applying thrombin to previously blood-soaked Interceed Barrier. The efficacy of Interceed Barrier applied after achieving hemostasis was further improved by moistening it with heparin. Achieving hemostasis at a bleeding site with thrombin facilitates the efficacy of Interceed Barrier.
