Medline OptiLock Super Absorbent Dressings

When a wound produces more drainage than a standard gauze pad can handle, the question isn't just how to cover it — it's how to lock that fluid away so it doesn't macerate the surrounding skin or soak through the bandage in an hour. That's the entire purpose of the Medline OptiLock line: superabsorbent polymer dressings built for moderate to heavily exuding wounds.

Each OptiLock dressing uses a polymer core that traps exudate and holds it inside the pad, even under compression, so fluid doesn't wick back to the wound bed. The result is a controlled moist environment at the wound surface and drier, healthier peri-wound skin. All versions here are sterile, non-adhesive, and identifiable by their familiar blue-and-white construction — the blue backing faces out, the white contact layer sits against the wound.

Sizing follows the wound, not the other way around. Smaller drainage sites are well served by the 3 x 3 inch (MSC6433EP) and 4 x 4 inch (MSC6444EP) pads, while the 5 x 5.5 inch (MSC6455EP) covers moderate areas. For heavily draining or larger wounds — venous leg ulcers, pressure injuries, post-surgical sites — the 6.5 x 10 inch (MSC64610EP) and 8 x 12 inch (MSC64812EP) dressings offer the greatest fluid capacity.

Because these are non-adhesive, they need a secondary retention layer — a wrap, tape, or tubular bandage — to hold them in place, which also makes dressing changes gentler on fragile skin. OptiLock fits naturally into a protocol alongside alginates for filling deeper cavities or as a standalone primary dressing on shallow, exuding wounds.
