The presence of redness, swelling, warmth, and discharge at the surgical site are well-established indicators of surgical site infection (SSI). These signs are part of the body's inflammatory response to infection. Redness around the incision indicates increased blood flow to the area as part of the immune response, swelling can signify the accumulation of fluids or white blood cells fighting the infection, warmth is often due to increased metabolic activity in the affected area, and discharge may indicate the presence of pus or other infectious materials.

Recognizing these signs early is crucial for timely intervention, which can prevent the infection from worsening or spreading. Surgical site infections can lead to serious complications, extended recovery times, and increased healthcare costs, so thorough monitoring for these indicators is an integral aspect of postoperative care.

In contrast, coldness and numbness typically suggest issues related to circulation or nerve damage rather than an infection. Symptoms like fatigue and nausea may indicate a broader systemic issue but are not specific to SSIs. Persistent cough and fever can be signs of respiratory infections or other systemic conditions but do not directly indicate an infection at the surgical site.
