Dressing is an essential part of nursing care, especially when it comes to treating wounds. There are several types of dressings, each with its own characteristics and uses. This chapter of the e-book "Complete Nursing Workbook: How to Treat Wounds and Dressings" will explore eleven types of dressings.
1. Dry dressings
Dry dressings are the most common and are used to protect minor wounds such as cuts and scrapes. They are made of an absorbent material that is placed over the wound and secured with tape. The purpose of this dressing is to protect the wound from infection and help stop bleeding.
2. Wet dressings
Wet dressings are used to treat wounds that are producing a lot of exudate or that have necrotic tissue. They are made from a material that is able to absorb moisture and help clean the wound. This type of dressing also helps maintain a moist environment that is conducive to wound healing.
3. Hydrogel dressings
Hydrogel dressings are gelatinous and keep moisture in the wound, promoting healing. They are used to treat dry or necrotic wounds as they help soften dead tissue so it can be removed. This type of dressing is also comfortable for the patient as it is fresh and does not adhere to the wound.
4. Foam dressings
Foam dressings are made from a polyurethane material that absorbs exudate from the wound. They are used to treat wounds that are producing large amounts of exudate. This type of dressing also helps protect the wound from mechanical damage.

5. Alginate dressings
Alginate dressings are made from seaweed and are highly absorbent. They are used to treat deep wounds that are producing a lot of exudate. This type of dressing also helps control bleeding, as the alginate forms a gel when it comes into contact with blood.
6. Hydrocolloid dressings
Hydrocolloid dressings are made from a material that forms a gel when it comes into contact with wound exudate. They are used to treat wounds that are producing small amounts of exudate. This type of dressing also helps maintain a moist environment that is conducive to wound healing.
7. Transparent film dressings
Clear film dressings are thin and adhere to the skin, protecting the wound from bacteria and dirt. They are used to treat minor wounds and to protect the skin around catheters and tubes. This type of dressing also allows the healthcare professional to view the wound without removing the dressing.
8. Collagen dressings
Collagen dressings are made from collagen, a protein that is essential for wound healing. They are used to treat wounds that are not healing well. This type of dressing helps stimulate new tissue growth and reduce inflammation.
9. Antimicrobial dressings
Antimicrobial dressings are impregnated with substances that kill bacteria, such as silver or iodine. They are used to treat infected wounds or to prevent infections in high-risk wounds. This type of dressing helps to reduce the bacterial load on the wound and prevent infections.
10. Negative pressure dressings
Negative pressure dressings use a machine to apply negative pressure to the wound, which helps promote healing. They are used to treat complex wounds that are not healing well with other methods. This type of dressing helps to reduce edema, promote the formation of new tissue and remove exudate from the wound.
11. Biological dressings
Biological dressings are made from natural materials such as pigskin or amniotic membranes. They are used to treat serious wounds such as burns or pressure sores. This type of dressing helps promote healing, reduce inflammation and protect the wound from infection.
In summary, choosing the appropriate dressing depends on several factors, including the type and severity of the wound, the amount of exudate produced, and the presence of infection. By understanding the different types of dressings available, nurses can make informed decisions about the best treatment for their patients.
