Hydrocolloid dressings are bandages or wound covers that contain a gel-forming agent, like gelatin.The gel agents are usually combined with a polyurethane foam or film to create a waterproof, bacteria-proof and oxygen-proof barrier. Hydrocolloid dressings are a popular wound dressing in hospitals and doctors' offices because the dressings adhere to wet and dry wounds. Hydrocolloid dressings come in sheets, gels or powders, although a hydrocolloid sheet needs to be placed on top of a gel or powder.

How to Use Hydrocolloid Dressing

1) Clean the wound.The wound should be cleaned with a gentle spray of warm water and rubbing alcohol or antibacterial soap, if recommended by a doctor.

2) Place your hand or a warm compress on the wound.Hydrocolloid dressings adhere best at room temperature, so the wound should be as close to room temperature as possible without getting bacteria inside the wound.

3) Apply the gel or powder, if necessary. If desired, a hydrocolloid gel or powder can be placed on top of the hydrocolloid sheet to allow a stronger barrier between the sheet and the wound. Gels and powders are especially helpful as wound fillers, if the wound is hollow or dips under skin level.
