What is Wound Care?
A wound is a break in the skin caused by an injury (a cut or blow), surgery or conditions such as diabetes. Wound care refers to the treatment and management of a wound until it heals, addressing the immediate medical needs as well as precautions for the future.
What is a Dressing?
A dressing is a sterile pad or gauze (compress) applied over a wound. The type of dressing used may depend on various factors such as the kind of injury, size, location and severity.
Types of Dressings
Hydrocolloid dressing: Used for burns, liquid emitting or necrotic wounds, and pressure or venous ulcers.
Hydrogel dressing: Used for dry or painful or necrotic or infected wounds, second-degree burns and pressure ulcers.
Alginate dressing: Used for wet wounds with high liquid drainage, burns, packing wounds, and venous or higher staged pressure ulcers.
Collagen dressing: Used for chronic or stalled or surgical wounds, transplant sites, ulcers, burns, pressure sores or large injuries.
Foam dressing: Used for wounds of varying degrees and severity including those that exhibit odours.
Transparent dressing: Used by medical professionals or medical carers.
Cloth dressing: Most commonly used dressing for all types of open wounds or broken skin. Suitable for minor injuries such as grazes, cuts, etc.
Purposes of Wound Care and Dressings
The main objectives of wound care and dressings are to:
- Help reduce pain and prevent infection
- Decrease purulent wound drainage
- Provide a clean and dry environment for healing
- Immobilize, protect and support the wound
- Ensure healing as fast and effective as possible
- Apply medication to the wound
Steps involved with Wound Care and Dressings
Typically, wound care and dressings involve:
- Bleeding control
- Wound cleansing
- Actual dressing of wound
This is the first and most important step. Bleeding can be stopped with pressure from the hands or with gauze if available or you can wait for the blood to clot (coagulate).
Once bleeding is controlled, the wound is cleansed with mild soap or liquid soap and warm water. The wound needs to be rinsed thoroughly with water to the entire depth from the surface. After the washing, the wound should be pat dried gently with a clean and soft towel.
Hands should be thoroughly washed and dried. Disposable gloves can be worn if available. A dressing that is slightly bigger than the wound to be covered should be used. Holding the dressing at the edges, the dressing should be applied while keeping the fingers away from the part that is going to cover the wound.
Dos and Don’ts of Dressing Wounds
- Always clean the wound before applying a dressing
- Leave the wound open if cleaning is not possible
- Seek medical advice on cleaning and dressing
- Change the dressing every 12 hours
- Do not dress a wound with visible infection
- Do not dress a bleeding wound. Stop the bleeding first before dressing the area.
