Which sign might indicate a surgical wound infection?

A surgical wound infection can present with several signs, each of which indicates that the healing process may be compromised and that there is a risk of infection. Excessive fluid discharge from the wound site often signals infection, as this can indicate an inflammatory response and the presence of purulent material. Temperature elevation, or fever, is a systemic response that the body mounts in reaction to infection, highlighting an increased immune response. Additionally, decreased pain sensation may occur due to nerve damage or the effects of infection which can alter pain perception.

The presence of these conditions collectively suggests that a surgical wound infection could be present, making "all of the above" the comprehensive answer that encompasses the variety of signs that may indicate a problem at the surgical site. Each sign contributes to the overall picture of a potential infection. Understanding these symptoms is crucial for postoperative monitoring and timely intervention.
