Triad hydrophilic wound dressing is a zinc-based paste that you apply directly to the wound bed, cover with a secondary dressing, and remove gently with a pH-balanced cleanser at each dressing change. It works on both dry and moist wounds, making it a versatile option for pressure ulcers, venous ulcers, burns, and other partial or full-thickness wounds.
What Triad Is and How It Works
Triad is a paste containing 15 to 25 percent zinc oxide along with carboxymethylcellulose (CMC), a plant-derived fiber that absorbs moisture. The CMC is what makes the paste “hydrophilic,” meaning it’s attracted to water. This lets it stick to wet wound surfaces rather than sliding off, which is a common problem with ointment-style dressings.
The zinc oxide serves a protective role, forming a barrier over the wound bed that shields it from irritants like urine or stool. This is why Triad is frequently used on skin affected by incontinence-associated dermatitis, where moisture damage and wound healing need to be managed at the same time. When covered with an appropriate secondary dressing, the paste also supports autolytic debridement, the body’s natural process of breaking down dead tissue using its own enzymes and moisture.
Which Wounds It’s Designed For
Triad is intended for a fairly broad range of wound types:
- Pressure ulcers at stages 2, 3, and 4
- Venous stasis ulcers
- Partial and full-thickness wounds
- Scrapes and skin tears
- First and second degree burns
- Tunneling wounds
Because of its zinc content and moisture-managing properties, it’s also commonly used on peri-wound skin that has been damaged by prolonged exposure to bodily fluids. If you’re caring for someone with incontinence and a wound in the sacral or buttock area, Triad can address both the skin breakdown and the wound itself.
How to Apply Triad Step by Step
Start by cleaning the wound with a gentle, pH-balanced wound cleanser. Normal saline also works. The goal is to clear away any debris or residue from a previous dressing without disturbing healthy tissue. Pat the surrounding skin dry but leave the wound bed itself moist, since Triad adheres well to wet surfaces.
Squeeze or spread the paste directly into the wound bed in an even layer. For shallow wounds, a thin coating is sufficient. For deeper wounds or tunneling wounds, you’ll want to fill the wound space so the paste makes contact with the entire wound surface. Don’t pack it too tightly; the idea is gentle contact, not compression.
Once the paste is in place, cover it with a secondary dressing. The choice of cover dressing matters, especially if you’re using Triad to support autolytic debridement. In that case, pick a cover dressing that retains moisture (such as a foam or film dressing) and can handle increased drainage as dead tissue breaks down. For wounds in the sacral area or other locations prone to contamination, a waterproof or moisture-resistant cover dressing helps keep the paste in place between changes.
How to Remove Triad Without Damaging the Wound
Removal is straightforward but requires patience. Spray or pour a pH-balanced wound cleanser over the paste to soften it. Coloplast, the manufacturer, specifically recommends their Sea-Clens wound cleanser for this purpose, though any gentle pH-balanced cleanser will work. Once the paste has softened, gently wipe it away. Do not scrub. If residue remains after the first pass, apply more cleanser and repeat the process until the wound bed is clear.
This gentle approach is important. Scrubbing can strip away the new tissue forming underneath and set healing back. If the paste is particularly adherent in one area, let the cleanser sit on it for a minute before wiping again.
How Often to Change the Dressing
Dressing change frequency depends on how much drainage the wound is producing. For wounds with minimal exudate, changes every two to three days are typical. Wounds with heavier drainage, or wounds undergoing active autolytic debridement (which increases fluid output), may need daily changes. If the secondary cover dressing becomes saturated, soiled, or detached before the scheduled change, replace it sooner.
Check the wound at each dressing change for signs of progress: the wound bed should gradually appear cleaner and pinker. If you notice increasing redness around the wound edges, a foul odor, or new drainage that looks green or cloudy, these may signal infection and warrant a clinical assessment.
Tips for Getting the Best Results
Triad works best when the secondary dressing is matched to the wound’s drainage level. Using an absorbent foam over a heavily draining wound prevents the cover from failing too quickly. Using an occlusive film over a dry wound helps retain the moisture needed for autolytic debridement. Getting this pairing right makes a noticeable difference in both healing speed and how long each dressing change lasts.
If you’re applying Triad to protect intact but damaged peri-wound skin (for example, around a stoma or in skin folds affected by moisture), a thinner layer works fine since you’re using the zinc as a barrier rather than filling a wound cavity. In these cases, you can reapply over existing paste if the layer is still intact, only fully removing and restarting when buildup becomes excessive or the skin underneath needs inspection.
Store the tube at room temperature. If the paste feels stiff when you squeeze it out, warming it briefly between your hands can make it easier to spread evenly across the wound bed.
