Hemostatic agents are materials used in surgery to control bleeding and achieve hemostasis, the cessation of blood flow from a damaged blood vessel. They act by promoting clot formation, either by directly interacting with blood components or by providing a scaffold for clot formation

There are two main categories of hemostatic agents: mechanical hemostatic agents, such as gauze and bandages, and biological hemostatic agents, such as fibrin sealants and thrombin

Hemostatic agents are used in a variety of surgical procedures, including trauma surgery, cardiovascular surgery, and neurosurgery. They can be used to control bleeding from a variety of sources, including arteries, veins, and capillaries

Hemostatic agents offer a number of advantages over traditional methods of bleeding control, such as suturing and electrocautery. They are easy to use, can be applied quickly and effectively, and are less likely to cause damage to surrounding tissues
