Hydrocolloid Dressings

All You Need To Know About Hydrocolloid Dressings

Reviewed by Christine Kijek, Registered Colorectal Nurse, on April 19, 2023

Hydrocolloids are known to have a unique design with an adhesive compound containing gel-forming agents like gelatin or sodium carboxymethylcellulose. This adhesive is laminated on a film or foam made from polyurethane, making the dressing absorbent, flexible, waterproof, and self-adherent.

Hydrocolloid wound dressings provide insulation and a moist wound environment conducive to healing. In addition, they use the moisture and enzymes of the body to hydrate the wound bed for faster healing.

Hydrocolloids are a type of wound dressing containing pectin, gelatin, and carboxymethylcellulose. When the hydrocolloid bandage is applied to the wound bed, the hydrophilic particles absorb the wound drainage and swell up. The swollen particles then liquefy and convert into a gel, enhancing the autolytic debridement. Subsequently, hydrocolloid dressings are impermeable to oxygen, water vapor, and carbon dioxide.

They are available in paste, gel, or sheet form and may be used as a primary or a secondary dressing. The gel or paste dressing needs a secondary dressing for proper security. When used as a secondary dressing, the wound surface should be in contact with alginate or gelling cellulose fiber.

• Absorbs wound exudate.
• Offers pain-free application.
• Does not adhere to the wound bed.
• Impermeable to bacterial contaminants.
• Flexible and waterproof to let you shower with it.
• Maintains a moist wound environment for quicker healing and tissue growth.

Hydrocolloid bandages are best suitable for treating non-infected and minimal exudate wounds, such as minor burns or pressure ulcers, also known as bed sores. Since these are flexible, difficult areas, such as elbows, heels, or knees can be dressed with hydrocolloids. 

Some of the conditions that warrant the use of hydrocolloidal dressings are -

• Acne
• Leg ulcers
• Open blisters
• Surgical incisions
• Granular and necrotic wounds
• Partial or full-thickness wounds
• Low to moderate drainage wounds

How to apply hydrocolloid bandage?

• Wash your hands properly. 
• Cleanse the wound with a saline solution.
• Use a sterile gauze to pat dry the peri-wound skin.
• Measure the dressing to leave an inch margin to cover the wound.
• Remove the paper liner and apply it to the center of the wound. 
• Smooth out the edges.
• Avoid overstretching or applying too much tension. Putting too much stress on it can cause trauma to the skin.
• Hold the dressing in place after applying.
• If your dressing does not have borders, use medical tape, undercast padding, netting, or retention bandage to secure it.

How to remove the dressing?

• Gently press down the skin near one edge of the dressing.
• Keep lifting off other edges until the adhesive detaches from the skin.
• Peel it off carefully from the wound in the direction of hair growth.

Frequently Asked Questions

1. When to change a hydrocolloid bandage?

Hydrocolloid bandages last up to three to seven days. Change the dressing if it starts to peel off from the edges. Since hydrocolloids keep the wound moist and protected, they need not be changed daily.

4. Can you use a hydrocolloid bandage for acne?

A hydrocolloid patch is safe to use on a scab, acne, or pimple. The moist environment of the hydrocolloid coating does not let it be dry, irritated, or itchy. Since hydrocolloid patches do not let you touch the wound constantly, it helps in quicker healing.

5. Can you use a hydrocolloid bandage for cold sore?
