RESUMEN
In infants and children, fever is very common in the emergency setting. The overall aim of the present publication was to overview guidance and provide an algorithm for use in the emergency setting as well as recommendations to inform parents for home care. To obtain consensus, a core steering committee drafted a management algorithm and general consensus was obtained by remote voting among experts. A number of common messages are found in current guidelines: management of fever depends on age, antipyretics are indicated only for discomfort; paracetamol or ibuprofen can be recommended; physical methods for lowering temperature are discouraged. A consensus algorithm is presented in which infants <28 days are considered separately, while those >28 days and <90 days are divided into those ill or well appearing. All infants <28 days with fever ≥37.5 °C should undergo complete work-up for sepsis, strongly considered to receive empirical antibiotics ± acyclovir, and be hospitalized. All infants (between 28 and 90 days) ill appearing should undergo diagnostic work-up for sepsis, receive empirical antibiotics, and be hospitalized. In well appearing infants, diagnostic work-up should be carried out to decide admission to hospital and administration of antibiotics. Specific recommendations are also given for home discharge that can be used to inform parents about the actions to take during home care in the attempt to reinforce existing guidelines. At present, physical examination and laboratory tests, along with best clinical judgement and postdischarge guidance following a defined algorithm, are the foundation of management of febrile children.
