Haemostatic dressings are impregnated with agents that help stop bleeding. The haemostatic dressings included contain products kaolin and chitosan. They are commonly used to control bleeding in the surgical and military settings but their use in the civilian, non-surgical setting is becoming more common.
When available and the first aid provider is trained in their use, we suggest that haemostatic dressings are of most value in the following situations.
Haemostatic dressings must be applied as close as possible to the bleeding point, held against the wound using local pressure (manually initially), then held in place with the application of a bandage if available. Haemostatic dressings should be left on the bleeding point until definitive care is available.
The need to control the bleeding is paramount. The risks associated with the first aid use of tourniquets and haemostatic dressings are less than the risk of uncontrolled severe, life-threatening bleeding. These adjuncts provide temporary bleeding control and rapid transfer to hospital remains critically important.
