The clinical manifestations, diagnosis, and differential diagnosis of hypothermia in children will be reviewed here.
Treatment of hypothermia in children, neonatal hypothermia, and frostbite are discussed separately. (See "Hypothermia in children: Management" and "Short-term complications of the preterm infant", section on 'Hypothermia' and "Frostbite".)
DEFINITION OF HYPOTHERMIA
Hypothermia is defined as a core body temperature below 35°C (95°F). The stage of hypothermia, defined by core temperature, has a major impact on both recognition and treatment. The most commonly used definitions found in the literature are as follows [1-4]:
●Mild – Core temperature 32 to 35°C (90 to 95°F)
●Moderate – Core temperature 28 to 32°C (82 to 90°F)
