Powder absorbable hemostat are hemostatic agents launched for controling bleeding by aiding in clot formation and are absorbed by the body over time. Absorbable hemostatic powders are commonly used in surgeries, trauma care, and minimally invasive procedures. Below are main types of powder absorbable hemostat.
Gelatin-based agents
Gelatin-based hemostatic agents are often used during surgical procedures. These agents come in sponge or sheet form and are designed to absorb blood while providing a matrix that helps platelets aggregate and form a clot. Gelatin agents are highly absorbent and can expand when placed in a wound, applying pressure that helps stop the bleeding. They are typically absorbed by the body over time, eliminating the need for removal.
Collagen-based agents
Collagen-based hemostatic agents are effective in promoting rapid clot formation. These agents work by attracting platelets to the wound site, where they trigger the body's natural clotting mechanisms. Collagen hemostats are commonly used in surgeries and trauma care because they help form a stable clot quickly and can be absorbed by the body.
Cellulose-based agents
Cellulose-based agents are often used in the form of gauze or bandages. These products transform into a gel-like substance upon contact with blood, which helps stop the bleeding by creating a physical barrier and promoting clotting. These agents are often used in first-aid settings and are popular in emergency trauma care, especially for treating wounds that bleed heavily. Additionally, prehospital topical hemostatic agents play a crucial role in managing severe hemorrhage during critical care situations outside of hospital settings, such as in emergency medical services, military operations, and trauma care.
Chitosan-based agents
Chitosan is a naturally occurring substance derived from chitin, found in the exoskeletons of crustaceans like shrimp and crabs. Chitosan-based hemostatic agents work by creating a mechanical barrier that seals the wound and physically seal bleeding wounds by bonding with red blood cells and platelets. These agents are used in both surgical settings and emergency trauma care, as they are biocompatible and do not rely on the body's natural clotting mechanisms, making them ideal for patients with clotting disorders.
Kaolin-based agents
Kaolin is a type of clay mineral that is used in some hemostatic agents to activate the body's clotting cascade. When applied to a wound, kaolin triggers the rapid formation of a clot by initiating the activation of clotting factors. Kaolin-based dressings and bandages are particularly useful in trauma situations where rapid bleeding control is needed, and they are often included in military and tactical first-aid kits.
Anti-hemorrhagic drugs
In addition to physical agents, certain medications known as anti-hemorrhagic drugs can also function as hemostatic agents. These drugs help stop bleeding by promoting clot formation or reducing the breakdown of clots. Anti-hemorrhagic drugs can be administered orally, intravenously, or topically depending on the situation. They are typically used in clinical settings to manage bleeding in patients with bleeding disorders, such as hemophilia, or in surgical settings to control excessive bleeding.
Potato starch-based hemostatic powders
Potato starch-based hemostatic powders are highly effective, natural, and biodegradable solutions for controlling mild to moderate bleeding. They are a valuable tool in surgical and emergency medicine due to their rapid action and ease of use. Typical potato starch-based hemostatic powders are Surgiclean Absorbable Hemostatic Powder, it is indicated in surgical as an adjunctive hemostatic device to assist when control of capillary, venous, and arteriolar bleeding by pressure, ligature, and other conventional procedures is ineffective or impractical.
