Analysis of the Therapeutic Efficacy of Alginate Dressings on Infected Wounds

Most infectious wounds are caused by trauma, surgery, and various types of catheterization that allow bacteria to invade localized areas, causing skin ulcers, suppuration and prolonging wound healing time, leading to physical and psychological pain for patients and increasing economic burden. In recent years, many studies have found that using at home medical supplies to cover wounds can keep the wound moist, which is more conducive to granulation growth and epidermal cell migration and accelerates wound healing. Under the guidance of this theory, wound care products fully utilize their advantages, reducing swelling, promoting wound healing, and minimizing trauma to the wound bed and surrounding skin due to their unique adhesive technology, resulting in significant wound healing effects.


Disadvantages of traditional dressing changes

The traditional wet dressing is basically in line with the theory of wet healing and still has a high clinical utilization rate. Its advantages are that it protects the wound, absorbs exudate, has wide raw material sources, is easy to make, and is cheap. However, its disadvantages are that it cannot keep the wound at a constant temperature and moisture level for a long time, scabs too early, dries too fast, and is not conducive to the growth of epidermal tissue. Gauze adheres to the wound surface and causes mechanical damage when changing the dressing, damaging fresh granulation tissue, causing unbearable pain to the patient’s wound, and frequent changes of the wound dressing can easily cause wound reinfection. If the at home medical suppliers bandage is wrapped too tightly, it can affect the circulation of the limbs and the growth of granulation tissue, and adhesive tapes can cause skin redness or insufficient adhesion, leading to contamination of the dressing. When changing the dressing for an infected wound, 3% hydrogen peroxide or anti-inflammatory agents need to be repeatedly rinsed, which affects wound healing when used for a long time. Traditional dressing not only increases the economic burden of patients but also increases the workload of medical personnel.


Advantages of wound care alginate dressings

People have gradually realized that the purpose of using at home medical supplies dressing is not only to cover the wound but also to help the wound heal, create the best environment to promote wound healing, and alginate dressings can change the dressing without damaging the new tissue, reducing bleeding and pain. They can keep the wound moderately moist, promote wound healing, and reduce immersion and further damage to the skin around the wound. The dressings are highly malleable and can be cut arbitrarily; they can quickly absorb a large amount of exudate and lock the wound, activating the body's own debridement mechanism and self-dissolving debridement to help remove infected necrotic tissue and avoid damage to surrounding normal tissue when cutting off necrotic tissue. At the same time, local microcirculation is improved. The dressings are easy and convenient to use, do not contain preservatives, and are tasteless. They can fill missing tissues, protect new granulation tissue, and promote epithelial formation. The adhesive technology of alginate dressings can reduce the number of dressing changes, allows for continuous observation of the wound, relieve pain for patients, and according to different needs, corresponding dressings can be selected for long-term maintenance of wound moisture, improving wound healing rate, reducing length of hospital stays and medical expenses, and achieving satisfactory clinical results.
