If a patient has a post-operative fever, what is the first intervention that should be considered?

In the context of a post-operative fever, administering fluids as the initial intervention is important for several reasons. Post-operative patients are at risk for dehydration due to a variety of factors, including loss of fluids during surgery, decreased oral intake, and ongoing bodily stress responses.

Fluid administration can help manage the patient's overall hemodynamic status, support renal function, and assist in regulating body temperature. Providing fluids may also help to promote tissue perfusion and support recovery.

While other interventions such as administering antibiotics, performing a physical exam, and initiating cooling measures are certainly important in the overall management of a post-operative fever, hydration should be prioritized, especially if there is any indication of hypovolemia or risk factors that suggest the patient may need additional fluid support. Each of these actions would follow based on the clinical presentation and ongoing assessment, but starting with fluid administration sets a foundation for stabilizing the patient.
