Approach To Newborn FEVER
Definitions
Fever is an extremely common pediatric presentation and has many different causes. Fever is not an illness but rather a sign. The physician’s job is to attempt to diagnose the cause of the fever and to determine if that cause requires treatment or not.
Fever is defined as a core body temperature greater than 38°C (100.4°F) in infants younger than 28 days and greater than 38.2°C in infants older than 1 month. Core body temperature is best estimated by rectal temperature.
