What can a sudden increase in a wound's drainage signify?

A sudden increase in a wound's drainage is often an indicator of possible infection. When a wound becomes infected, the body's immune response kicks in, leading to increased fluid production as the body attempts to flush out pathogens. This drainage can be purulent, meaning it may contain pus, which is a sign of infection, indicating that bacteria are present and actively multiplying.

In contrast, an improving condition typically leads to a reduction in drainage as the wound starts to heal and tissue regeneration occurs. The normal healing process may involve some drainage, but significant increases can signal complications rather than normal physiological responses. Increased blood flow generally results in increased warmth and redness around a wound, which is different from a sudden increase in drainage. Recognizing these signs can help healthcare providers promptly address any potential complications, such as infection, ensuring better patient outcomes.
