The Role and Contraindications of Hydrocolloid Dressings

Hydrocolloid dressing is an elastic dressing composed of medical pressure-sensitive adhesive and hydrophilic colloid particles. Many friends want to know: what are the effects and contraindications of hydrocolloid dressing? Hydrocolloid dressing is a new type of medical sterile dressing, mainly composed of sticky material, hydrophilic hydrocolloid (CMC), and artificial elastic materials.


I. Effects of Hydrocolloid Dressing


1. Treatment of various low to moderate exudative wounds.


2. Used for the prevention and treatment of lower limb venous ulcers.


3. Used for the prevention and treatment of stage I-II pressure ulcers.


4. Moist wound dressing are used to treat small area superficial burns.


5. Treatment of postoperative wounds.


6. Used for skin grafting wounds.


7. Treatment of various superficial injuries and plastic surgery wounds.


8. Used for the granulation and epithelialization phases of chronic wounds.


II. Contraindications of Hydrocolloid Dressing


1. Hydrocolloid moist wound dressing products are not recommended for wounds with severe infection, exposure of bone, muscle and tendon, and excessive exudation.


2. After contact with wound exudate, hydrocolloid dressing forms a gel. When the dressing is opened, material and odor similar to pus can be seen in the wound, and sometimes changes in color and swelling can be observed. This is the material and odor formed by the breakdown of the substance in the dressing itself and the protein in the exudate.


3. It cannot be used for wounds with superficial to full-thickness damage or wounds with moderate to large amounts of exudate.


4. For wounds with excessive granulation tissue growth and a large amount of exudate, foam dressings like foam dressing with silicone border can be used to maintain local moisture and cleanliness with strong exudate absorption ability, and elastic bandages can be used to inhibit the growth of granulation tissue.


5. Keep the wound moist and the surrounding skin dry to avoid affecting wound healing due to excessive frequency of dressing changes.


III. How to Use Hydrocolloid Dressing


Hydrocolloid dressing is a commonly used wound dressing that can effectively absorb wound exudate and maintain the moisture of the wound, thereby promoting the growth of granulation tissue and epidermis.


Hydrocolloid dressing is a commonly used wound dressing in clinics, mainly composed of carboxymethylcellulose sodium synthetic elastic materials, which can absorb wound exudate, maintain the moisture and sealing of the wound, and provide a good healing environment for the wound. It can be used for the prevention and treatment of venous inflammation and superficial ulcers. Among various dressings, the absorption capacity of hydrocolloid dressing for exudate is generally moderate, so it can only be used for wounds with low or moderate exudate, and the wound must have completed debridement, which is clean and free of necrotic tissue and debris. In addition, hydrocolloid dressing can only be used for superficial wounds, and the effect is relatively poor in deep wounds that cannot be reached internally.


Special conditions where hydorcolloid moist wound dressing cannot be used: wounds infected with anaerobic bacteria, full-thickness wounds, crust wounds, deep wounds, diabetic feet, wounds that are likely to continue necrosis, and bleeding wounds, which can be treated with skin-creating ointments, healing-promoting ointments, and gauze.
