Hemostatics, also known as hemostatic agents, are substances or pharmaceuticals designed to control and promote the cessation of bleeding. Their primary purpose is to facilitate hemostasis, the physiological process that stops bleeding, either by promoting vasoconstriction, platelet aggregation, or by enhancing the coagulation cascade. These agents find crucial applications in surgical and medical settings, trauma care, and emergency medicine. One common type of hemostatic agent is the topical hemostat, often used in surgeries to control bleeding from small blood vessels or capillaries. These agents may include materials like absorbable gelatin, collagen, or cellulose-based compounds, which create a physical barrier and encourage clot formation at the site of application. In addition to topical hemostatics, systemic hemostatic agents may be administered internally to address more severe bleeding disorders or conditions. These can include medications that influence platelet function, clotting factors, or fibrinolysis. The development and use of hemostatics have significantly improved the safety and success of medical procedures, allowing for better control of bleeding and reducing the risk of excessive blood loss. However, their application requires careful consideration of the patient's overall health, the nature of the bleeding, and potential interactions with other medications. Hemostatics continue to be essential tools in modern medicine, contributing to improved patient outcomes and recovery.
