The Role of Alginate Ag Dressings and Requirements for Wound Care

Alginate medical wound dressing products mainly consist of calcium alginate, a natural cellulose extracted from seaweed, which is mainly used for the care of superficial wounds. When covered on the wound surface, it can effectively absorb excess wound exudate and form a soft mesh gel, thus maintaining a good moist environment and promoting wound repair and healing. Alginate has good hydrophilicity and biocompatibility. Its application on superficial wounds can help to suppress bacteria, stop bleeding, and promote healing. It can also be applied to small and deep sinus wounds to promote wound drainage and pus discharge.


The use of alginate ag dressings has strict requirements for wounds


Before use, make sure the wound is clean and free of necrotic tissue. If there are black scabs, necrotic tissue, or viscous pus, a debridement process should be carried out first to keep the wound flat and clean before covering the wound with alginate. Wash the wound with saline water and dry the surface with a cotton ball. Cut the alginate dressing according to the size of the wound and gently cover it on the surface of the wound, making sure that the dressing is attached to the bottom of the wound. Then use sterile gauze to wrap and fix it. During the initial stage of wound repair, the alginate ag dressing should be changed once a day. When the wound inflammation is under control, the exudate is reduced, and granulation tissue begins to form, the frequency of dressing changes should be reduced.


When alginate ag dressings are soaked with exudate, it indicates that their water absorption capacity is basically saturated and needs to be replaced in a timely manner. Generally speaking, the longest time for dressing change should not exceed seven days. Alginate ag dressings have obvious advantages in the early stage of wound repair and are mainly used for clean wounds. If it is a bad and corrupt wound, or there are black scabs, cavities, and deep injuries, it is necessary to go to a specialized hospital for wound repair treatment as soon as possible, and then carry out nursing with dressings after debridement.


Alginate ag dressing mainly helps wounds in the following aspects


Promote wound healing


Compared with other dressing products, the water absorption capacity of alginate ag dressings is relatively strong, and they can absorb a large amount of wound exudate, forming a moist gel state to maintain the moist and low oxygen environment of the wound. In this environment, epidermal cells can move and proliferate freely, and the growth rate of granulation tissue and new epithelium is accelerated.


Help stop bleeding


For the bleeding symptoms of fresh wounds, after covering with alginate ag dressings, calcium ions can be released on the surface of the wound to promote the formation of prothrombin activator, thus accelerating the clotting process.


Isolate external pathogens


After the skin is ruptured, pathogens are easy to invade the wound. However, covering alginate ag dressings can effectively isolate external pathogens, avoid pathogen invasion, and provide a moist, low-oxygen, and slightly acidic environment conducive to the activation of white blood cells, enhance local bactericidal ability, and reduce the incidence of infection.


Will not adhere to the wound


Alginate ag dressings have good affinity and can be easily removed after absorbing moisture without adhering to the wound, causing no pain during dressing changes.


Compared with traditional gauze, although alginate wound dressing products is more expensive, it can shorten the time of wound repair, reduce local inflammation reactions, and improve the quality of wound healing in many ways, which can alleviate the patient's pain. Therefore, its application prospects are quite broad.
