Diagnosis of a wound infection

How to diagnose a Wound Infection?

Diagnosing a wound infection involves assessment of the wound for presence of local or systemic symptoms of infection.

Inflammation is the most significant classic indicator of wound infection. It includes redness (rubor), increased heat (calor), swelling (tumor), pain (dolor), and loss of function (functio laesa).

The 5 signs of inflammation.
To obtain an accurate diagnosis, clinical assessment must be carried out – this includes blood tests, scans, surgical procedures, and microbiological testing. Professor Karen Ousey talks about the procedures involved in more detail in the video above.

Biofilms are complex microbial communities that adhere strongly to a living or non-living surface. Microorganisms co-exist in a network and secrete and synthesize an extracellular protective polymeric substance which aids in its firm attachment to the surface. This protective polysaccharide layer does not allow the body’s immune system to detect the presence of the microorganisms. They effectively evade an immune response, survive standard treatments, and multiply. In this way, they can withstand nutrient and moisture deprivation, altered pH, and the impact of antibiotics and antiseptics. Microorganisms routinely colonise, contaminate, and infect wounds. Existing in biofilms enable bacteria to resist the effects of antimicrobial agents and host defences in the wound bed.
