Kendall Curasorb Calcium Alginate Dressing — Gel Block Technology, 20x Absorption, 6 Sizes

Vertical wicking. High calcium. Minimal shrinkage. One-piece removal. Kendall Curasorb Calcium Alginate Dressings are sterile, highly absorbent primary wound dressings engineered with a unique fiber configuration that sets them apart from standard calcium alginate dressings. Where most alginates absorb laterally — spreading exudate outward toward the wound margins — Curasorb's gel block fiber structure encourages vertical wicking, pulling exudate straight through the dressing for more efficient removal and reduced risk of periwound maceration. The formula features a higher percentage of guluronic acid than standard alginates, producing a stable, cohesive gel that maintains dressing integrity through the full wear period and allows clean one-piece removal with minimal tissue trauma. The unique calcium-to-sodium ratio actively donates calcium to the wound while removing sodium, supporting the ion exchange that initiates epithelialization and speeds hemostasis. Available in 6 sizes — pads from 2"x2" to 6"x10" plus a 12" rope for cavity and tunneling wounds.

✔ Gel Block Technology — Vertical Wicking, More Efficient Exudate Removal    ✔ Absorbs Up to 20x Its Weight    ✔ Donates Calcium, Removes Sodium — Regulates Wound Bed    ✔ High Guluronic Acid — Stable Gel, Easy One-Piece Removal    ✔ Minimal Shrinkage — Protects Periwound Skin    ✔ 6 Sizes Including Rope

Product Details & Available Sizes

Indicated For — Wound Types

• Pressure ulcers — all stages
• Venous insufficiency ulcers
• Arterial ulcers
• Diabetic foot ulcers
• Deep and tunneling wounds — use rope for cavity packing
• Partial thickness (second-degree) burns
• Donor sites
• Abrasions, lacerations, and skin tears
• Moderately to heavily exudating wounds requiring frequent exudate management

Contraindications: Not indicated for wounds with dry eschar or minimal exudate — insufficient wound drainage can cause dressing adherence. Do not use on third-degree burns.

What Makes Curasorb Different — The Technology Behind the Dressing

Most calcium alginate dressings are built from a standard mix of mannuronic and guluronic acid polymer chains. The ratio between these two components determines how the dressing behaves at saturation: mannuronic-heavy alginates produce a softer, more elastic gel that can spread and fragment; guluronic-heavy alginates form a firmer, more cohesive, stable gel. Curasorb is formulated with a higher percentage of guluronic acid, which produces a denser, more stable gel matrix that holds its form through the wear period — making the dressing easier to remove cleanly without leaving fiber or gel fragments in the wound bed, and maximizing patient comfort at dressing change.

The second key distinction is the gel block fiber configuration. Standard alginates absorb exudate horizontally — spreading laterally across the dressing face and toward the wound margins. This lateral spread can deposit absorbed exudate against the periwound skin, increasing maceration risk. Curasorb's gel block fiber design channels exudate vertically upward through the dressing body rather than outward. The result is more efficient fluid capture, better protection of the periwound border, and reduced maceration — allowing the dressing to be worn longer between changes even on moderate-to-heavy draining wounds.

The third differentiator is the calcium-to-sodium ratio. Curasorb is engineered with high calcium levels and an isotonic sodium configuration. As wound exudate contacts the dressing, sodium from the wound fluid exchanges with calcium in the alginate fibers. Curasorb's formulation is designed to maximize this exchange — actively donating calcium back into the wound environment (which supports hemostasis and the clotting cascade) while efficiently removing sodium (which, in excess, can inhibit cellular proliferation and delay healing). The isotonic sodium configuration ensures the exchange is gentle and non-irritating to wound tissue.

• Higher guluronic acid percentage — firmer, more stable gel that holds integrity and removes cleanly
• Gel block fiber configuration — vertical wicking draws exudate through the dressing, not toward wound margins
• Minimal shrinkage — dressing maintains its coverage area as it gels, protecting the periwound border
• High calcium levels — speeds hemostasis and supports the healing cascade
• Isotonic sodium configuration — gentle on wound tissue, non-irritating ion exchange
• Donates calcium, removes sodium — actively regulates the wound bed ionic environment
• Jump-starts epithelialization — the calcium-sodium exchange initiates cellular migration signals
• Up to 20x absorption — reduces dressing change frequency on high-drainage wounds
• One-piece painless removal — minimizes tissue trauma and patient discomfort at dressing change

Choosing the Right Size

• 9232 — 2" x 2": Small wounds, pressure injuries on bony prominences, vascular access or pin sites, small skin tears and abrasions — any wound where a compact dressing footprint is needed
• 9233 — 4" x 4": The most versatile and commonly used size — standard pressure ulcers, diabetic foot ulcers, venous leg ulcers, and surgical wounds of average size. Cut with sterile scissors to fit smaller wound shapes.
• 9240 — 4" x 5½": Slightly extended pad ideal for wounds that run longer than a standard 4x4 — surgical incisions, elongated leg ulcers, and heel wounds where added length provides full coverage without requiring two pads.
• 9238 — 4" x 8": For larger flat wounds — wide pressure ulcers, extensive donor sites, larger surgical wounds, and wounds across the sacrum or trochanter where a 4x4 would require overlapping multiple dressings.
• 9239 — 6" x 10": Largest pad size — extensive wounds, large burn surfaces, wide venous ulcers on the lower leg, or any wound requiring broad surface coverage in a single dressing application.
• 9231 — 12" Rope: For cavity wounds, tunneling wounds, sinus tracts, and deep irregular wounds. Loosely packed by fluffing and layering into the wound cavity — never tightly compressed — to ensure exudate access to the fiber surface throughout the wound depth.

Application Instructions

1. Using forceps or sterile gloves, apply the Curasorb dressing to the wound bed as the primary dressing
2. For flat wounds: apply pad directly to wound surface — select a size with minimal overlap onto periwound skin
3. For cavity/tunneling wounds: fluff the rope and loosely pack by layering back and forth into the wound cavity — do not pack tightly, ensure dressing does not overfill or compress wound margins
4. Cover with an appropriate secondary dressing to secure and provide additional absorbency as needed
5. Change when secondary dressing reaches absorbent capacity, or as wound condition warrants — typically every 1–3 days; may be left up to 7 days on lower-drainage wounds

Removal: Gently remove secondary dressing, then lift Curasorb dressing from the wound bed — the stable guluronic gel formula and vertical wicking design allow the dressing to lift in one piece with minimal residue. If any adherence occurs, moisten with sterile saline before removing.
