Advanced Bleeding Control
How to Use a Haemostatic Dressing
Haemostatic gauze is made for the serious bleeds ordinary dressings cannot control. It helps the body form a clot, but it still needs to be placed at the bleeding point and held there with firm pressure.

Quick Answer
Call Triple Zero (000), lie the person down and apply firm direct pressure. If life-threatening bleeding is from a site unsuitable for a tourniquet—or a tourniquet is unavailable or has failed—a trained first aider may apply a haemostatic dressing. Place it as close as possible to the bleeding point, maintain firm pressure for the time specified by that product, secure it if possible and leave it in place until definitive care.
This is for life-threatening bleeding
Haemostatic gauze is not a premium dressing for an ordinary cut. It is specialised equipment for bleeding that threatens life. Pressure and rapid ambulance transfer remain essential.
What Is a Haemostatic Dressing?
A haemostatic dressing is gauze or another trauma dressing impregnated with an agent intended to support clot formation. You may also see the US spelling, hemostatic dressing. In Australian first aid guidance, haemostatic is the usual spelling.
The important distinction is between a pre-hospital trauma dressing and the many haemostatic products used during surgery or specialist wound care. This guide is about external bleeding control by a trained first aider. It does not describe dissolvable surgical materials, internal products or routine wound dressings.
ANZCOR Guideline 9.1.1 identifies kaolin- and chitosan-containing dressings in the underlying evidence. It does not recommend one specific brand as universally best. The dressing is an adjunct: local pressure is still what holds it against the bleeding point while a clot forms.
Where It Fits in Severe-Bleeding First Aid
- Start with pressure. Apply firm pressure on or around the wound. In life-threatening bleeding, control of bleeding takes priority over airway and breathing interventions.
- Use a tourniquet for suitable limb bleeding. If severe bleeding from an arm or leg is not controlled by pressure, a trained first aider should use an arterial tourniquet when one is available.
- Use haemostatic dressing where a tourniquet does not fit the problem. This includes bleeding from a site unsuitable for a tourniquet, limb bleeding when a tourniquet is unavailable, or bleeding that continues after a correctly applied tourniquet.
- Arrange urgent hospital care. Both devices temporarily control bleeding; neither replaces hospital treatment.
Tourniquet vs Haemostatic Dressing
| Situation | Preferred bleeding-control approach |
|---|---|
| Most external bleeding | Firm direct pressure on or around the wound |
| Life-threatening bleeding from an arm or leg, uncontrolled by pressure | Commercial arterial tourniquet when trained and available |
| Life-threatening bleeding at a site unsuitable for a tourniquet | Haemostatic dressing with firm direct pressure when trained and available |
| Suitable limb bleed but no tourniquet available | Continue direct pressure; use haemostatic dressing if trained and available |
| Correctly applied tourniquet has not stopped bleeding | Check it, add a second tourniquet above it if available, and consider haemostatic dressing in conjunction |

Kaolin, Chitosan and Product Types
Modern trauma dressings use different materials and mechanisms. Kaolin-containing gauze supports the body’s coagulation pathway. Chitosan-containing products interact with blood to help form an adhesive barrier. Both still depend on close contact with the bleeding point and sustained pressure.
Common formats include Z-folded gauze designed for wound packing and pad-style dressings designed for surface application. Some products are intended for specific clinical environments. Check that the product is suitable for your setting, listed for supply in Australia where applicable, within its expiry date and stored in an intact package. The Therapeutic Goods Administration product register is one place to verify Australian device entries.
Do not assume a powder, surgical sponge, dental product or routine absorbent dressing can be used in the same way as trauma gauze. Follow the instructions for the exact product in your first aid kit.
How to Use a Haemostatic Dressing
This is a hands-on skill, and the exact method varies between products. Follow the instructions supplied with the dressing in your kit, especially for wound packing, pressure time and approved uses.
- Make the scene safe and call Triple Zero (000). Use gloves and protective glasses if readily available.
- Lie the person down and expose the wound. Apply immediate pressure. Do not remove an embedded object; press around it.
- Find the bleeding point. The dressing must contact the source rather than sitting loosely on pooled blood at the surface.
- Apply the dressing as close as possible. If trained and the product is intended for wound packing, feed the gauze firmly into the wound cavity, starting at the bleeding point. Do not improvise invasive packing in the chest or abdomen.
- Maintain firm direct pressure. Use the time specified by the product instructions. There is no single pressure time that applies to every haemostatic dressing.
- Reassess without pulling the dressing out. If bleeding continues, maintain pressure and follow the product and emergency-service instructions. A second dressing may be required for some wounds.
- Secure it. When bleeding is controlled, hold the haemostatic material in place with a firm bandage if available.
- Leave it in place. Continue monitoring the person until paramedics take over. Give them the product packaging or name if possible.
Mistakes to Avoid
- Using haemostatic gauze for a minor cut that responds to ordinary pressure and dressing.
- Treating it as a substitute for pressure. The gauze must be held firmly against the source.
- Placing it loosely on top of a deep wound instead of applying it as the product and training require.
- Using one memorised pressure time for every brand and format.
- Removing the dressing to check the wound and disrupting the developing clot.
- Confusing trauma gauze with dissolvable surgical material or routine wound-care products.
- Delaying a tourniquet when life-threatening limb bleeding is suitable for one.
- Delaying Triple Zero (000) or hospital transfer after bleeding appears controlled.
After the Dressing Is Applied
Keep the person still, lying down and warm. Continue to monitor response and normal breathing. Watch the outside of the secured dressing for renewed bleeding, but do not pull out the haemostatic material to inspect underneath it.
Tell paramedics where the dressing was placed, when it was applied, what product was used and whether bleeding restarted. If the person is taking anticoagulant medicine or has a known bleeding disorder, pass that information on as well. The dressing should remain against the bleeding point until the hospital team takes over.

Learn Advanced Bleeding Control
Correct application is tactile: you need to identify the source, place the material where it matters, maintain pressure and secure it without disturbing the clot. A written guide cannot reproduce that practice.
