Molnlycke Mesalt Sodium Chloride Impregnated Dressing — 20% NaCl, Heavily Exuding & Infected Wounds, 3 Formats

Salt pulls. Mesalt cleans. Mesalt by Molnlycke is a sterile, non-woven viscose/polyester dressing impregnated with 20% sodium chloride that uses osmotic action to actively draw exudate, bacteria, and necrotic material out of the wound bed and into the dressing. Where standard dressings passively absorb whatever fluid reaches them, Mesalt's hypertonic sodium chloride creates an osmotic gradient — a concentration difference between the dressing and the wound environment — that attracts fluid, bacterial load, and debris toward the dressing and away from the wound. This makes Mesalt particularly effective during the inflammatory phase of healing, when wound bioburden is high and the wound needs active cleansing to progress. Applied dry directly to the wound bed in a single piece. Available in three formats: 4x4 inch square (285580), 6x6 inch square (286099), and 3/4 x 39 inch ribbon for cavity and tunneling wounds (285280).

Product Details & Available Formats

Indicated For — Wound Types & Applications

• Heavily exuding wounds in the inflammatory phase — primary indication
• Infected wounds requiring active bacterial reduction and cleansing
• Moderately to heavily draining chronic wounds — pressure ulcers, venous leg ulcers
• Surgical wounds with high exudate or bacterial burden
• Cavity wounds, tunneling wounds, and fistulas — ribbon format (285280)
• Deep pressure ulcers requiring packing
• Hypergranulation tissue — sodium chloride reduces excessive granulation
• Moist necrosis requiring debridement support
• Sloughy wounds with significant bacterial load

Do not use Mesalt on: Dry wounds or wounds with little to no drainage — the osmotic mechanism requires wound moisture to function and can desiccate a dry wound. Avoid direct contact with exposed bone or tendon. Do not use on patients with known hypersensitivity to product materials. Do not reuse.

How Mesalt Works — Hypertonic Osmotic Cleansing

Standard absorbent dressings work by capillary action — they passively pull fluid into the dressing matrix as it contacts the dressing surface. Mesalt works differently. The 20% sodium chloride impregnated into the dressing creates a hypertonic environment — a salt concentration significantly higher than the fluid in the wound bed. Osmosis drives fluid from areas of lower solute concentration toward higher solute concentration, so wound exudate, bacteria, and cellular debris are actively drawn into the dressing rather than simply absorbed passively.

• Osmotic exudate draw — the high NaCl concentration in the dressing pulls wound fluid, dissolved proteins, and bacterial components toward and into the dressing, reducing bioburden in the wound bed
• Bacterial absorption — bacteria suspended in wound exudate are drawn into the dressing along with the fluid and trapped there — reducing the bacterial load in the wound environment
• Necrotic material removal — necrotic debris and slough are drawn toward the dressing and absorbed, facilitating autolytic debridement of the wound bed
• Hypergranulation reduction — the hypertonic sodium chloride environment reduces excessive granulation tissue by drawing moisture out of the hypergranulating cells, helping the wound return to a normal healing trajectory
• Applied dry — Mesalt is applied directly to the wound surface without pre-moistening; the wound's own exudate activates the osmotic mechanism on contact
• Single piece application and removal — the dressing is applied and removed in one piece, simplifying the dressing change process and reducing the risk of leaving fiber residue in the wound bed

Choosing the Right Format

• 285580 (4x4" Square) — Standard size for flat, moderately to heavily exuding wounds. Covers most pressure ulcer, venous ulcer, and surgical wound footprints. Delivered folded to 2x2 inch — unfold to 4x4 for placement. Box of 30.
• 286099 (6x6" Square) — Larger format for wounds requiring extended coverage. Delivered folded to 3x3 inch — unfold to 6x6 for placement. Box of 30. This is the SKU on the Vitality Medical listing.
• 285280 (3/4" x 39" Ribbon) — For cavity wounds, tunneling wounds, fistulas, and deep pressure ulcers where a flat dressing cannot reach the wound bed. The ribbon is loosely packed into the wound cavity — do not pack tightly. Box of 10.

Application Instructions

1. Cleanse the wound with sterile saline and remove any loose debris
2. For flat wounds (285580, 286099): unfold the dressing and apply dry directly to the wound bed, ensuring full wound surface coverage
3. For cavity wounds (285280 ribbon): loosely pack the ribbon into the wound cavity — do not pack tightly, as swelling occurs as the dressing absorbs exudate
4. Cover with an appropriate secondary dressing — Mepilex Border or equivalent to keep Mesalt in place
5. Where clinically indicated, compression therapy may be applied over Mesalt for venous wounds
6. Change when the dressing is saturated — at least once daily, more frequently if exudate volume is high
7. To remove: moisten the dressing with sterile saline if adherent before removing — remove in one piece; irrigate wound bed to clear any residual sodium chloride
