What is an early sign of infection in a surgical patient?

Fever and chills are considered early signs of infection or an inflammatory response in a surgical patient. After surgery, the body’s immune system may react to surgical trauma, and any increase in temperature, even if mild, can indicate that the body is fighting off an infection. The presence of chills often accompanies a fever, further reinforcing the body’s response to an infectious process. Monitoring vital signs, including temperature, is a crucial aspect of post-operative care, as early identification of fever allows for prompt intervention and management, which is essential to prevent further complications.

Increased urination may relate to various factors post-surgery, such as fluid management or diuretics, but it does not specifically indicate an early infection. Low blood sugar is also not directly linked to infection; rather, it may occur due to fasting or changes in metabolic state after anesthesia. Chest pain could result from multiple causes post-surgery, such as respiratory complications or cardiovascular issues, but it is not a typical early indicator of infection. Therefore, recognizing fever and chills is essential in the context of surgical recovery and complications associated with infections.
