Which sign could indicate a potential infection at the surgical site?

Swelling and increased warmth at the surgical site are key indicators that can signify a potential infection. These signs often result from inflammatory processes that occur when the body is responding to an infectious agent. When infection is present, the body's immune system increases blood flow to the area, which can lead to warmth; simultaneously, swelling occurs as fluid and white blood cells accumulate at the site of infection.

In clinical practice, it is crucial to monitor these signs closely after surgery. Early detection of infection can significantly improve outcomes, as timely intervention, such as antibiotics or drainage procedures, may be necessary to prevent complications. Recognition of these signs is part of routine postoperative care to ensure that any deviations from normal healing processes are addressed promptly.
