Objective: Major vascular injury is one of the most important causes of death after trauma. The effective and speedy control of the hemorrhage is crucial in reducing deaths. Many products are used for this purpose. Today, however, an ideal product has not yet been produced and there is a strong demand for such effective hemostatic products. The aim of this study is to compare the efficacy of Algan hemostatic agent with Floseal in the liver laceration model in rats. Materials and Methods: A total of 28 rats were used in the study. Rats were divided into 4 groups, each consisting of 7 rats. Experimental liver laceration was established. In the control group, saline-impregnated gauze was applied. Algan hemostatic agent-impregnated sponge, Algan hemostatic agent powder, and Floseal gel were applied to the experimental groups. Results: There was no difference in bleeding control among the Algan hemostatic agent powder, Algan hemostatic agent-impregnated sponge, and Floseal. When compared to the control group, Algan hemostatic agent powder, Algan hemostatic agent-impregnated sponge, and Floseal were found to be very effective in bleeding control, respectively (P=.001, .012, and .002), in the experimental groups. Conclusion: This study showed that the properties of both Algan hemostatic agent powder and Algan hemostatic agent-impregnated sponge for controlling bleeding are similar to Floseal. Considering other characteristics such as Algan hemostatic agent’s naturalness, easy applicability, and low cost, Algan hemostatic agent has been a promising effective hemostatic agent.
