Technological developments with wound treatment dressings

Dressings are long-established in the medical field for keeping wounds clean and preventing secondary infections. Dressings are essential for reducing infection risk; more recent advancements have seen dressings developed to promote wound healing.

In relation to this, Tim Sandle has written an article for Infectious Disease Hub. Here is an extract:

Wound healing refers to a specific biological process related to the general phenomenon of growth and tissue regeneration. Wounds heal by the control of moisture and by a process of staving off infection; while dressings have addressed the former over centuries, with the latter specialized dressings are being developed. Dressings to aid wound healing have been used for several decades, such as the use of hydrocolloid dressings to help treat burns and with the application of hydrogels for wounds that are leaking little or no fluid. However, it is in more recent years that antimicrobial compounds have been incorporated.

This involves the addition of physical or chemical processes designed to kill any pathogenic microorganisms that might be present, and which pose a risk of triggering a disease such as sepsis (where the chemicals that body’s immune system releases into the bloodstream to combat an infection trigger inflammation throughout the entire body) or delay the rate of wound healing (one of the causes of delayed wound healing is the presence of microorganisms in the wound). This article examines some of these developments, and also considers an additional development in the form of color-changing dressings for signaling the presence of antimicrobial-resistant bacteria.
