Hydrogel is commonly used, the main component of the dressing and veneer compound dressing, providing elastic composite fit and occlusive clinical sodium, providing elastic suture of the wound, wound exudate, keeping the wound moist and moist, available For the prevention and treatment of inflammation, and for superficial wounds.


A variety of wound dressings may be used in daily wound treatment, such as common hydrocolloid dressings, alginate dressings, foam dressings, silver ion dressings, and active dressings. Similarly, the following focuses on the most commonly used hydrocolloid dressings.


Among various dressings, hydrocolloids have a moderate ability to absorb exudate, so they can only be used for wounds with low or moderate exudate, and the wound must have been debridement and the wound surface is clean and free of slough and dirt. In addition, hydrocolloids can only be used for superficial wounds, and deep wounds cannot reach the interior, so the effect is relatively poor.


The hydrocolloid dressing is simple and convenient to use, and does not need to be replaced frequently. It is usually replaced every 3-5 days. At this time, because the dressing absorbs too much exudate and the viscosity decreases, it will not cause pain and damage when removing. However, if the use time is too short, and the forced removal of the dressing will damage the skin around the wound, especially the new granulation tissue and delicate epidermis, special attention should be paid to this.

After the hydrocolloid dressing absorbs the exudate, it will turn into a gel, which will swell locally and turn white. Therefore, attention should be paid to observe the degree of exudate absorption of the dressing during use, and the whitened area should be replaced in time when it is close to the edge of the dressing (such as 1 cm).

In the care of chronic ulcer wounds and phlebitis, the hydrocolloid dressing should not be forcibly torn off, but should be pressed on one side of the dressing with one hand, and the dressing should be pulled to the opposite side with the other hand and slowly peeled off. Due to the dry and fragile skin of the elderly, the dressing change or removal process should be done with care.


Special situations in which hydrocolloid dressings should not be used: anaerobic infection wounds, full-thickness wounds, scabbed wounds, deep wounds, diabetic foot, wounds that may continue to necrosis, and bleeding wounds.
