What is a hydrocolloid dressing?
A hydrocolloid dressing is a type of dressing that provides a moist and insulated healing environment. Hydrocolloid dressings protect uninfected wounds and allow the body’s own enzymes to assist in the healing process. Hydrocolloid dressings are easier to apply than other dressings and they generally don’t need to be changed as frequently.
Most hydrocolloid dressings contain gel-like agents which help the wound to heal. They have a waterproof (usually polyurethane) backing which adheres to the skin. Hydrocolloid dressings are available in a wide range of shapes and thicknesses, and they can be purchased with or without an adhesive border.
When to use a hydrocolloid dressing. Hydrocolloid dressings are ideal for wounds that are free from dirt and debris. They are also suitable for dry wounds that don’t require drainage.

How to apply a hydrocolloid dressing
Hydrocolloid dressings are easy to apply, and simply require standard wound-care techniques. For best practice application, follow these steps:
1) Wash hands and wear gloves
2) Remove any previous dressings
3) Clean wound with saline
4) Pat wound dry with gauze
5) Apply a moisture barrier or wound cavity filler as needed
6) Select a hydrocolloid dressing that is roughly 3cm larger than the wound
7) Apply the dressing from the centre of the wound
8) Ensure the adhesive is smooth against the skin
When to change the dressing
Hydrocolloid dressings usually last between three to seven days. If the dressing starts to peel from the edges before this time, it will need changing.
The great thing about hydrocolloid dressings is that they keep the wound moist and protected. This means that the wound will not need to be cleaned every day. In fact, the wound will heal faster if you keep the dressing on and don’t regularly expose it to air.

• Lift up the corner of one of the adhesive edges
• Gently lift around all edges until all the adhesive is free
• Remove the dressing from the wound in the direction of hair growth
• Replace with new dressing if required.
When are hydrocolloid dressings not suitable?
Hydrocolloid dressings are not suitable for all types of wounds. In particular, these dressings should not be used on wounds that are infected or require drainage.
Hydrocolloid dressings are not ideal for wounds that require regular assessing as it can be difficult to see the wound without removing the dressing.
Individuals with fragile skin may find that the adhesive nature of these dressings can cause skin trauma when being removed.
Is it safe to use Hydrocolloid Dressings on Patients with Diabetes?

• The patient has been thoroughly assessed

• There is no sign of infection
• The wound does not require drainage
