Background: Hemostasis plays a crucial role during every surgery allowing for a bloodless operating field. Fast and effective surgery leads to a reduced risk of postoperative complications. One of the latest methods for achieving homeostasis is using natural polysaccharide-based hemostatic powders. The study aimed to evaluate the biocompatibility according to the ISO 10993 standards of 4SEAL® Hemostatic powder.
Methods: Chemical characterization (Headspace GC-MS, GC-MS, and ICP-MS), cytotoxicity, genotoxicity (MLA and AMES), endotoxin contamination, sensitization potential, intracutaneous reactivity, acute and subacute systemic toxicity with implantation, and pyrogenicity were evaluated to investigate the biocompatibility of the 4SEAL® Hemostatic powder. Studies were conducted according to ISO 10993 standards.
Results: The biocompatibility requirements according to ISO 10993-1 for 4SEAL® Hemostatic powder were met. Based on the conducted in-vitro studies, 4SEAL® Hemostatic powder shows a non-cytotoxicity and non-mutagenic potential. Also, the results of in vivo studies of 4SEAL® Hemostatic powder shows no signs of toxicity, non-sensitizing, non-irritating, and no pyrogenicity potential. In the chemical characterization of 4Seal® Hemostatic Powder, no compounds were identified above Analytical Evaluation Threshold (AET) and no elements with concentrations higher than element-specific PDE [μg/day] were detected.
Conclusions: 4SEAL® Hemostatic powder is a promising new hemostatic agent with a wide range of potential applications and excellent biocompatibility.
