Hydrocolloid dressings are made from a hypoallergenic water-like adhesive and polyurethane or polyurethane foam for contact with the wound. The hydrophilic polymer is usually carboxymethyl cellulose (CMC). Additionally, the Hydrocolloid dressing is easy to tailor and can be tailored to the anatomy for the best results.
Pros of Hydrocolloid Dressing:
1. Keep the wound moist, create a low-oxygen, slightly acidic environment to accelerate wound healing
2. It has the effect of autolytic cleansing and has the effect of dissolving fibrinogen
3. Greater absorption, faster absorption speed.
The improvement of the inner layer structure, especially containing CMC particles, has the ability to absorb a small to medium amount of exudate.
4. Form a gel to protect the exposed nerve endings, relieve pain and not cause mechanical damage again
Cons of Hydrocolloid Dressing:
1. Can not be used for wounds with a lot of exudate
2. Sealed wounds, infected wounds cannot be used
Clinical application of Hydrocolloid dressing
According to the theory of wound healing, Hydrocolloid dressing is generally used in the middle and late stages of healing, that is, the granulation stage and the epithelial stage. At this time, the wound exudation is reduced, but a moist environment needs to be maintained to promote the growth of granulation and epithelium.
