What type of dressings have effectively stopped bleeding in surgical patients with severe coagulopathy?

Chitosan dressings have shown significant effectiveness in controlling bleeding, particularly in patients with severe coagulopathy, which is a condition where the blood's ability to clot is impaired. Chitosan, a natural biopolymer derived from chitin, promotes hemostasis in two main ways: it actively enhances blood coagulation and creates a physical barrier to blood loss. When applied to a wound, chitosan dressings can rapidly absorb blood and form a gel-like substance that supports clot formation, even in cases where traditional clotting mechanisms may not function correctly due to coagulopathy.

In surgical patients specifically, where the risk of severe bleeding is high, the use of chitosan dressings provides an additional intervention beyond standard gauze or foam dressings and supports a rapid response to prevent further complications from trauma or extensive surgery. They are particularly valuable in pre-hospital settings or emergency contexts where quick action is necessary.

Other types of dressings, while useful in various contexts, do not offer the same level of efficacy in this specific situation. Gauze dressings may be helpful but do not possess the same hemostatic properties as chitosan. Compression bandages can assist with bleeding control but may not be sufficient on their own when dealing
