What should be investigated if a patient's temperature increases significantly after treatment?

When a patient's temperature increases significantly after treatment, it may indicate a fever. A fever can be a physiological response to various factors, including infection or inflammation. In the context of dialysis or other treatments, it's crucial to monitor temperature as it could reflect complications such as an underlying infection or a reaction to treatment.

Investigating the cause of the fever is essential to ensure appropriate medical intervention. If the increase in temperature is due to an infection, prompt treatment may be necessary to prevent further complications.

Other possible reactions like dehydration or non-specific reactions to treatment can occur, but a notable increase in temperature is generally more indicative of a fever that warrants further evaluation. Ignoring this symptom could lead to overlooking a serious condition, thus the need for a thorough investigation.
