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.
