Alginate ag dressing has good absorption and compliance, and has a wide range of applications, which can be used for the treatment of various wounds. Such as full-thickness or partial skin gaps containing slough and necrotic tissue with extensive exudation, including infected wounds and wounds with sneak and/or sinus tracts. The gel formed after absorbing the exudate will form a good moist environment in the wound, and promote the wound autolytic debridement and the growth of granulation tissue. Formation of the gel depends on sufficient fluid, so alginate ag dressing cannot be used on wounds with little exudation and wounds covered with crusts of necrotic tissue.
The alginate ag dressing containing silver ions has both high absorbency and anti-infection effect, which is very suitable for infected wounds with a lot of exudation, such as infected pressure ulcers with a lot of exudation. For shallow wounds, heavily exuding wounds, such as lower extremity ulcers, a sheet dressing can be used, while for cavity wounds, a strip alginate ag dressing should be used. For epithelial wounds, alginate ag dressings are preferred to cellulose dressings because they are easier to remove without causing pain. Alginate ag dressings like alginate foam dressing can be used in combination with other dressings such as hydrocolloid dressings, foam dressings and silver ion dressings.
I. Clinically applicable symptoms of alginate ag dressing
1. Treatment of exudate and local hemostasis.
2. Wounds with moderate or severe exudates and cavities, such as pressure ulcers and bedsore wounds.
3. Diabetic foot ulcer wounds, lower extremity venous and arterial ulcer wounds.
4. Burn donor site wounds and refractory burn wounds in the Department of Burns.
5. Bleeding and exudate from the wound after anorectal anal fistula operation.
II. Skills in using alginate ag dressing
1. Cover with a second layer of dressing.
2. When the alginate ag dressing is soaked by the exudate, it needs to be replaced in time; it should not be used in combination with the hydrogel dressing.
3. If an alginate ag dressing containing silver is used, the dressing must be removed during MRI examination.
4. The wound is relatively dry, and the dressing is not glued or adhered to the wound. When removing, soak it with normal saline and then remove it.
5. Do not use too many dressings when filling the wound, so as not to affect the wound healing.
6. Be sure to rinse the wound bed with normal saline after each antimicrobial alginate dressing change.
III. Precautions for alginate ag dressing
1. Antimicrobial alginate dressing can be used for the treatment of infected wounds, but it should be used under the guidance of medical staff and in conjunction with other treatment measures. Moreover, medical staff need to frequently evaluate the clinical indications of patients and check the wound condition.
2. If the wound is mainly caused by arterial insufficiency or diabetic foot ulcer, the conditions for using antimicrobial alginate dressing are: use it under the guidance of medical staff, and medical staff need to frequently evaluate the clinical indications of the patient and check the wound condition.
3. Antimicrobial alginate dressing is not suitable for massive and continuous bleeding that cannot be controlled by the body's physiological mechanism and must be stopped by surgical means.
4. Antimicrobial alginate dressing is not recommended for dry wounds.
5. If the cumulative use time of antimicrobial alginate dressing exceeds 30 days after multiple replacements, its genotoxic and subchronic toxicity effects have not been confirmed.
