Hemostatic efficacy of two topical adjunctive hemostats in a porcine spleen biopsy punch model of moderate bleeding.

Topical hemostatic agents have become essential tools to aid in preventing excessive bleeding in surgical or emergency settings and to mitigate the associated risks of serious complications. In the present study, we compared the hemostatic efficacy of SURGIFLO Hemostatic Matrix Kit with Thrombin (Surgiflo-flowable gelatin matrix plus human thrombin) to HEMOBLAST™ Bellows Hemostatic Agent (Hemoblast-a combination product consisting of collagen, chondroitin sulfate, and human thrombin). Surgiflo and Hemoblast were randomly tested in experimentally induced bleeding lesions on the spleens of four pigs.

Evaluation of the Hemostatic Efficacy of Two Powdered Topical Absorbable Hemostats Using a Porcine Liver Abrasion Model of Mild to Moderate Bleeding.

Introduction: Topical hemostatic agents, used alone or in combination, have become common adjuncts to manage tissue and organ bleeding resulting from trauma and surgical procedures. Oxidized regenerated cellulose (ORC) is one of the most commonly used adjunctive hemostatic agents. The aim of the present study was to compare the hemostatic efficacy of a novel ORC-based product, SURGICEL® Powder Absorbable Hemostat (Surgicel-P) to that of HEMOBLAST™ Bellows (Hemoblast-B), a collagen-based combination powder.

An analysis of ISO intracutaneous reactivity test results to justify a reduction in animal requirements.

The ISO intracutaneous reactivity test is the standard protocol for determining a medical device's potential for causing irritation. The authors present data indicating that the number of animals required per test can be reduced from three rabbits to two.
