[Ways to reduce fever: are luke-warm water baths still indicated?].

Tepid sponge bathing to reduce temperature may be an aggression against the febrile child organism leading to reactions that will limit the cooling. During the bath, the decrease of the skin temperature induces not only peripheral vasoconstriction, shivering, and metabolic heat production, but also a discomfort. This discomfort occurs when there is a difference between the thermal informations coming from the body and the central thermoregulator set point. It triggers crying when the child has no way to escape. Considering the little effectiveness (0.3 degree C on average) of the association bath cooling and antipyretic treatment versus antipyretic treatment, and the preservation of the child comfort, bathing in tepid water is not useful in current care of children fever.

[Selective brain cooling].

The brain is especially sensitive to heat stress. To limit the increase of intracranial heat in case of hyperthermia or fever, a system of selective cooling is put on. It includes two heat-exchangers. The first one, in the face and scalp skin, disperses calories through sweat evaporation. The second one is intracranial, close to the arteries which irrigate the brain. They are connected by a vascular network. In these conditions, the arterial blood temperature, of which cerebral temperature depends upon, is reduced by the cooled venous blood which comes from subcutaneous tissues through the skull wall. On feverish children, increasing such a selective cooling by face fanning can limit cerebral thermal stress.

[Thermal comfort and fever or research on how to feel better].

Thermic comfort is the affective perception of temperature (to be or not comfortable). It depends on the difference between thermoregulatory central set point and body temperature. Any measures which help to reduce this difference is felt as pleasant, and vice-versa. This must be taken into consideration in the prescriptions and advices for feverish children. Thus antipyretic therapy, and face fanning are always felt as pleasant, while undressing and tepid baths may be felt as unpleasant.
