Hemorrhage remains a big threat to trauma patients, especially in combat fields. Therefore, we formulated a biocompatible and biopolymer based chitosan/carrageenan composite dressing. This dressing was fabricated using freeze-drying that will serve as a promising material to promote hemostasis and tissue growth required during hemorrhage. The efficacy of dressing was evaluated for its physiochemical analysis, surface morphology, and biodegradability. Further, human dermal fibroblast cells were seeded on dressing and demonstrated non-toxic effects on the cells by showing enhanced cell attachment and proliferation. In vitro hemostatic properties of the dressing were analyzed by human Thrombin-Antithrombin assay. The dressing formed showed steady blood coagulation implying red blood cells and platelet adhesion that helped in thrombin formation, which is responsible for enhancing wound healing. Thus, it is concluded that the composite dressing can be a potent combination to accelerate hemostatic activity against hemorrhage and promote tissue growth for effective wound healing.
