Hydrofera Blue Classic Ostomy Ring Dressing with Moisture-Retentive Film — PVA Foam, Antibacterial, HBRF2650

The only antibacterial foam ostomy ring dressing — for infected or severely irritated peristomal skin where a standard barrier ring isn't enough. Hydrofera Blue Classic Ostomy Ring Dressing (HBRF2650) is a 2.5" diameter PVA foam dressing specifically designed to be worn directly against the peristomal skin, under any ostomy skin barrier, when standard barrier rings (such as Adapt, Eakin Cohesive, or Brava) are insufficient because the skin around the stoma is infected, ulcerated, or severely irritated. Made from open-cell polyvinyl alcohol (PVA) foam — a fundamentally different material from standard polyurethane foam — impregnated with methylene blue and gentian violet, the same dual-pigment antibacterial system used throughout the Hydrofera Blue line. The moisture-retentive film backing faces the ostomy appliance, allowing the skin barrier to adhere normally over the top without interference. Cut-to-fit up to 2" center opening. Must be hydrated with sterile saline or water before application. 10 dressings per box.

When to Use Hydrofera Blue Ostomy Ring Dressing

Standard ostomy barrier rings — including moldable hydrocolloid rings like Adapt, Eakin Cohesive Seal, and Brava — are excellent for filling peristomal contour irregularities and preventing leaks, but they provide no antibacterial protection. When the skin around the stoma becomes infected, ulcerated, or severely irritated — conditions common in patients with high-output stomas, frequent leaks, contact dermatitis, or post-operative stomal complications — a standard barrier ring maintains the mechanical seal but does nothing to address the underlying bioburden or support wound healing in the compromised peristomal tissue.

Hydrofera Blue Ostomy Ring Dressing is specifically indicated for exactly this situation: when the peristomal skin cannot heal because bacterial colonization, exudate accumulation, and ongoing skin breakdown are creating a wound environment under the appliance that standard pouching practice alone cannot resolve. The dressing sits directly against the compromised peristomal skin, wicks bacteria-laden exudate away from the wound surface, delivers continuous antibacterial activity through the methylene blue and gentian violet pigments, and supports the natural wound healing process — all while the ostomy appliance is worn normally over the top.

• Indicated when peristomal skin shows signs of infection, ulceration, or severe irritation that standard barrier rings cannot address
• For use following stomal surgery when post-operative peristomal wound management is required under the pouching system
• For patients with high-output or frequently leaking stomas where ongoing peristomal skin breakdown has created a wound environment
• As an alternative to standard ostomy rings when bioburden management is a clinical priority
• For management of peristomal candidiasis, bacterial infection, or moist desquamation

Why PVA Foam — How It Differs from Standard PU Foam

The Hydrofera Blue Ostomy Ring is made from polyvinyl alcohol (PVA) foam, not the polyurethane (PU) foam used in most wound dressings including the Hydrofera Blue READY line. PVA foam has a distinct physical structure — its open-cell architecture provides extremely high wicking efficiency and moisture-holding capacity relative to its volume, exceptional softness against fragile peristomal tissue, and a surface texture that conforms closely to irregular wound surfaces without exerting pressure. The combination of PVA's exceptional absorption and retention with the methylene blue and gentian violet pigments creates a dressing that continuously pulls bacteria-laden exudate from the peristomal wound surface, traps the bacteria in the dressing matrix, and maintains a clean, moist wound bed — all without releasing antibacterial agents into the tissue or inhibiting the cellular healing process.

• PVA open-cell foam — extremely high wicking efficiency and fluid retention relative to dressing volume
• Extreme softness — conforms closely to peristomal skin contours without pressure point creation
• Methylene blue and gentian violet kill bacteria within the dressing — antibacterial action stays in the foam, not in the wound bed
• Non-cytotoxic — does not inhibit fibroblasts or growth factors; supports granulation tissue formation throughout use
• Facilitates autolytic debridement — the moist environment and mechanical wicking action support natural wound bed preparation
• Effective against gram-positive bacteria (including MRSA), gram-negative bacteria, and yeast (including VRE)
• Pigments physically bind to endotoxins in wound fluid, reducing bacterial load and associated patient discomfort

The Moisture-Retentive Film Backing — How It Works with the Ostomy Appliance

The shiny side of the Hydrofera Blue Ostomy Ring Dressing is the moisture-retentive film backing. This film serves two functions: it retains moisture within the foam (keeping the hydrated PVA foam active and preventing premature drying between changes), and it provides the surface against which the ostomy skin barrier adheres. The film has been tested and confirmed not to interfere with the adhesion of standard ostomy skin barriers — the appliance is applied directly over the film side of the dressing as it would be applied to clean, dry peristomal skin. This means the full pouching system functions normally, the seal integrity is maintained, and the antibacterial wound management occurs simultaneously and invisibly beneath the wafer throughout the wear period.

Application Guide — Step by Step

• Step 1 — Prepare: Remove the ostomy appliance per your standard change protocol. Gently cleanse the peristomal skin with warm water or normal saline and allow to dry completely. Debride any loose necrotic tissue if present per clinical protocol
• Step 2 — Cut to fit: Measure the stoma diameter. Using clean scissors, cut the center opening of the ring to match the stoma size — the center can be cut to fit stomas up to 2" in diameter. The ring should fit snugly around the stoma base without gaps
• Step 3 — Hydrate the foam: Remove the dressing from the sterile package. Hydrate the exposed foam side (not the film side) with approximately 25–30 cc of sterile saline or sterile water. Squeeze out excess liquid gently with sterile gloves or forceps — the foam should be moist but not dripping
• Step 4 — Apply: Place the dressing with the hydrated foam side directly against the peristomal skin — the film (shiny) side must face outward, away from the skin. Position the ring snugly around the stoma base
• Step 5 — Apply skin barrier and appliance: Apply the ostomy skin barrier and pouch system directly over the film side of the dressing as you would normally. The film does not interfere with barrier adhesion
• Step 6 — Change schedule: Change the first dressing at 24 hours. If the dressing has retained its blue color, subsequent dressings can remain in place for up to 72 hours. If the dressing turned white or lighter, the pigments are depleted — continue 24-hour changes until the blue color is retained at the 24-hour mark, indicating the bacterial load has decreased to a manageable level
• Removal: If the dressing has dried and adhered, do not pull — rehydrate with sterile saline or water and remove gently with forceps. Apply skin barrier to periwound skin if needed to protect from maceration

The Color Change Indicator — Reading the Dressing at Change

Like all Hydrofera Blue Classic dressings, the ostomy ring turns from blue toward white as the methylene blue and gentian violet pigments are consumed in their antibacterial function. The color at the time of change is a direct indicator of the wound's bacterial status. A dressing that is still blue at 24 hours indicates that the bacterial load was manageable — subsequent changes can safely extend to 72-hour intervals. A dressing that turned white by 24 hours indicates the pigments were fully consumed fighting a high bacterial load — continue daily changes until the dressing holds its color, signaling that the infection is coming under control. This provides a simple, objective, change-by-change picture of peristomal wound progress without requiring laboratory assessment.
