Hydrocolloid Dressings - Introduction | How it Works | When to Use | Types & Brands | Research & Articles
Hydrocolloid wound dressings provide a highly-effective moist environment, which is ideal for healing. Gel-forming agents are mixed with adhesives plus elastomers and then applied to a polyurethane foam or film. The gel-forming agents form a gel on coming into contact with the exudate. The viscosity of the gel will depend on the gel-forming agents contained within. Some may form a thick gel while others may lead to a watery one. The moist environment provided by the hydrocolloid is conducive to quick recovery of the wound. Generally, the dressing is impermeable to moisture but once the gel forms, the dressing becomes absorbent thus pulling in more and more exudate. The moist core of FlexiCol Hydrocolloid Wound Dressing allows for higher and quicker fluid uptake so there is very little residue remaining behind on the wound.
Hydrocolloid dressing brands that are highly effective include 3M Tegaderm, DuoDerm dressings, Comfeel, RepliCare, Nu-Derm, Exuderm and Cutimed. The Medline Exuderm LP has a dressing change frequency of maximum of seven days and depends on the amount of drainage. It can be used for primary, secondary, shallow and moderate wounds. The 3M Tegaderm hydrocolloid dressing is thin and provides a viral barrier while staying intact without leakage. It is available in oval and square and multiple sizes. The Derma dermaGran B hydrophilic Wound Dressing is ideal for external wounds and gives a moist wound environment for quick healing.
