Use of a plant-based polysaccharide hemostat for the treatment of sternal bleeding after median sternotomy

Abstract

Background: In cardiac surgery profuse or persistent sternal bleeding after sternotomy is routinely controlled with bone wax. However, bone wax should be avoided, especially in high-risk patients for nonunion of the sternum and infections. Purpose of this study was to evaluate an alternative technique to control bleeding after medium sternotomy using a plant based absorbable polysaccharide hemostat. Methods: A consecutive series of 38 patients requiring median sternotomy for coronary artery bypass surgery (21 OPCAB, 17 CABG) had sternal bleeding control with the polysaccharide hemostat, STARSIL® HEMOSTAT. This hemostat is a hydrophilic powder, which achieves hemostasis after topical application at the surgical wound site. Initially it dehydrates blood rapidly, thus accelerating aggregation of platelets and blood solids. Thereafter, it forms a gelled adhesive matrix, which serves as a mechanical barrier against further bleeding. The polysaccharide is completely resorbed within 48 to 72hours. Results: Satisfactory control of sternal bleeding was observed in 37 patients (97%). No product-related complications were observed or any other major adverse events in an observation period of 3months. Conclusion: Polysaccharide hemostats appear to be safe and effective for bleeding control of the sternum.
