Understanding the Variety of Wound Dressings at First Aid Distributions
The first question to ask isn't what dressing to buy. It's what state the wound is in. How wet, how clean, how fragile the skin around it. Get that right and the dressing usually picks itself.
Around 450,000 Australians live with a chronic wound at any given time, and chronic wounds cost the health system an estimated $6 billion a year (Monash University, 2025). A meaningful share of that cost comes from dressings being used in the wrong situation. Choosing well makes a real difference.
We carry the full clinical range of dressings stocked in Australian hospitals, aged care, and community nursing. Here's how the main types of wound dressings work, and how to pick what fits.
Start with the wound, not the dressing
Every dressing does some combination of four jobs: hold a moist healing environment, manage moisture (either soak it up or add it), reduce contamination risk, and stay in place without damaging the skin around the wound. The right product is the one that matches what the wound actually needs from that list.
When you look at a wound, four things drive the dressing choice: how much fluid (exudate) it's producing, whether infection is a risk, how the surrounding skin is holding up, and how often you can change the dressing without disturbing healing.
Wounds that produce a lot of fluid
High-exudate wounds need products that absorb without sitting wet against the wound bed. The main categories you'll see used clinically:
- Alginate dressings (Aquacel, Kaltostat). Made from seaweed fibres, they absorb fluid and form a soft gel over the wound bed. Useful for moderate-to-heavy exudate and for packing cavity wounds.
- Foam dressings (Mepilex, Allevyn, Biatain). Thicker, soft, comfortable. They suit pressure injuries, leg ulcers, and post-surgical sites. Some come with silicone or adhesive borders.
- Superabsorbent pads (Zetuvit Plus, Mextra). For very wet wounds. They lock fluid away from the skin and protect the wound edges from maceration.
- Hydrofiber dressings (Aquacel Extra). Similar to alginates with even higher fluid uptake.
If a dressing is at capacity inside 24 hours, you're either under-dressing the wound or it needs a clinician's eyes.
Dry wounds that need moisture
The opposite problem matters just as much. Dry wounds heal slowly. The principle behind modern wound care is that moist wounds heal faster than dry ones. Two categories add moisture or hold it in:
- Hydrogels. Water-based gels and sheets, around 70 to 90 per cent water. They rehydrate dry wounds and soothe painful ones. Good when a wound bed has dried out and healing has stalled.
- Hydrocolloids (Duoderm, Comfeel). Self-adhesive, retain moisture, and let the wound bed soften under them. Useful for minor abrasions, light-exudate wounds, and longer wear times.
The clinical shorthand is straightforward. If it's dry, wet it. If it's wet, soak it. Get that wrong and healing slows down.
Wounds at risk of infection
Antimicrobial dressings reduce the bacterial load on wounds that are infected or at high risk of becoming infected. They are not for clean, healing wounds.
The mechanism varies by product. Silver dressings (Mepilex Ag, Aquacel Ag, Acticoat) release silver ions over time. Iodine dressings (Inadine) release iodine. PHMB and honey-based dressings work on different mechanisms again. All are listed on the ARTG.
A clinical rule worth knowing: silver dressings are typically used as a two-week challenge. Apply for two weeks, reassess. If infection signs have resolved, switch to a non-antimicrobial dressing. Silver isn't a permanent choice, and prolonged use on clean wounds can slow healing rather than help it.
If a wound shows signs of infection (spreading redness, warmth, pus, fever, increasing pain) and it isn't responding within a few days, the right step is a clinician's review rather than a longer course of dressings. ALWAYS READ THE INSTRUCTIONS FOR USE before applying any antimicrobial product.
Wounds on fragile skin
Two categories matter when skin around the wound is thin, papery, or easily torn:
- Non-adherent dressings. They lift cleanly off the wound at change. Useful for partial-thickness burns, skin tears, and any case where the wound bed is too vulnerable for an adhesive dressing.
- Silicone-interface dressings (Mepitel, Mepilex Border). The contact layer is silicone, which holds onto the dry skin around the wound without sticking to the wound itself. They reduce trauma at every dressing change.
Skin tears are common in older Australians. Residential aged care prevalence sits between 41 and 59 per cent, the highest rate in the world (Rayner et al., Wound Practice and Research, 2018). For anyone caring for an elderly parent, a relative on blood thinners, or someone with very thin skin, silicone-interface dressings are usually the first call.
The everyday cover: gauze, island, film
Most home, school, and workplace first aid kits run on the basic primary and secondary dressings:
- Gauze (sterile and non-sterile). Breathable, low cost, useful as a secondary layer or for minor wounds. Not ideal in direct contact with healing wounds, where it can dry and stick.
- Combine dressings. Larger absorbent pads for trauma or heavy bleeding before professional care arrives.
- Island dressings (Cutiplast, Primapore, Opsite Post-Op). A non-stick pad in the centre with an adhesive perimeter. Good for post-surgical sites and tidy cuts.
- Film dressings (Tegaderm, Opsite Flexigrid). Transparent, semi-permeable. They let oxygen and moisture vapour through. Good as a secondary dressing or for protecting IV sites and minor wounds.
For severe bleeding, haemostatic dressings (QuikClot, Celox) speed up clotting and belong in trauma kits, remote-area kits, and high-risk workplaces. They aren't the right tool for chronic wound management.
How to choose the right dressing
The shortest route to the right product is to read the wound, not the marketing:
- Wet wound: alginate, foam, or superabsorbent.
- Dry wound: hydrogel or hydrocolloid.
- Infected or high-risk wound: antimicrobial, with reassessment in two weeks.
- Fragile skin: silicone-interface or non-adherent.
- Minor wound or cover layer: gauze, island, or film.
- Severe bleeding: haemostatic.
For complex, chronic, or non-healing wounds, the dressing choice should come from a clinician who has actually looked at it. Wound nurses, GPs, and community nursing teams are the right call, particularly for older patients, diabetic ulcers, and slow-healing wounds. The Chronic Wound Consumables Scheme, launched in June 2025, fully subsidises wound dressings for eligible Australians with diabetes-related chronic wounds aged 65 and over (50 and over for First Nations people), through participating health professionals.
We stock all of the categories above, including the clinical sizes and bulk quantities that pharmacy chains don't carry. Thirty years of nursing and a few more running this business has taught me one thing: the most common mistake people make is matching the dressing to what they recognise from the chemist shelf, not to what the wound actually needs.
