New Material for Wound Dressings Helps Heal Wounds Faster

Today, wound care treatment is not about just applying stitches and gauze, but has become far more sophisticated with skin bioengineering, anti-scarring strategies and much more. However, there are several limitations with existing wound dressing materials that can delay the healing of a wound. Recently, a group of scientists developed a new material for wound dressing applications that can help heal wounds faster. The scientists tested this biomaterial on the wounds of mice and found that their wounds healed completely within two weeks, faster than existing commercial dressings.

Wound DressingsIn the opinion of the lead study author, healthcare providers will have to deal with more patients with pressure ulcers and other chronic skin wounds as the global population ages. So, there is the urgent need for an ideal dressing that can speed up the healing process in addition to preventing bacterial infection. However, all the current options available have shortcomings in one way or another. Whether it is alginate, hydrofiber, antimicrobial, silver or hydrogel dressings, a secondary dressing is required to keep them in place. Certain hydrocolloid dressings may adhere to the wound or remain too difficult to remove. Though the damp environment provided by hydrogels can help healing, it won’t give adequate air circulation for the wound. Dry films with tiny pores allow the air to move in and out of the wound. But the blood cells and bacteria may stick to the films and adversely affect the healing process. In order to prevent such issues, scientists are always on the lookout for new materials and now they have developed something really useful.

The scientists introduced a pseudo-zwitterionic structure bearing moieties with mixed positive and negative charges to develop the biomaterial. They attached the zwitterions to a porous dry film and the resulting material remained slick to cells and bacteria. The material kept a moist environment, allowed adequate air circulation and promoted healing. Pseudo-zwitterionic structure retained the ideal combination of major properties of efficient dressings such as hydration property, resistance to fibrinogen adsorption, hemocompatibility, resistance to fibroblast attachment and bacteria colonization.

Even though this technology will come into practice, it is very important to ensure that patients are getting its advantage at the right time. Wound assessment is an important part in determining the appropriate management of a wound. Usually, nurses assess the initial wound and help to develop a treatment plan that aid in wound healing. They need to document their notes as well for wound care physicians to determine the best treatment options. Electronic documentation can speed up this process and thereby facilitate the provision of the right treatment at the right time.
