Vérzéscsillapító

A vérzéscsillapító, or hemostatic agent, is a substance used to promote the cessation of bleeding by accelerating blood clot formation. These agents are critical in medical, surgical, and emergency settings to control hemorrhage and minimize blood loss.

Hemostatic agents can be classified into topical and systemic types. Topical hemostatics are applied directly to bleeding tissues. They include powders, gauzes, sponges, and bandages infused with substances that activate the clotting process. Common materials include oxidized regenerated cellulose, gelatin, chitosan, and thrombin. Systemic hemostatics are administered intravenously or orally to promote clotting throughout the body, often used in patients with bleeding disorders such as hemophilia.

The primary function of a vérzéscsillapító is to facilitate the natural clotting cascade by providing a physical matrix for clot formation or by supplying clotting factors. For example, thrombin-based agents directly convert fibrinogen into fibrin, forming a stable clot. Chitosan, derived from shellfish, promotes coagulation by interacting with red blood cells and platelets, regardless of traditional clotting pathways.

Vérzéscsillapító agents are widely used in surgeries, trauma care, dental procedures, and in emergency kits. Their effectiveness depends on proper application, the nature of the bleeding, and the specific agent used. Recent advancements focus on improving biocompatibility, ease of use, and effectiveness in non-compressible bleeding.

While generally safe, some hemostatic agents may cause allergic reactions or complications such as inflammation or infection if improperly used. Their selection and application require careful consideration by healthcare professionals to ensure optimal outcomes.
