We practice in an era of outcome based medicine. It’s not enough anymore, at least when it comes to things like blood pressure and blood sugar, just to treat the numbers (cosmetic treatment). Why, then, in everyday practice, don’t we apply the same rigorous skepticism to the problem of fever?
A recent study in Critical Care looked at the question. Lowering of body temperature was not associated with improved outcomes and in some patients was harmful.
Don’t forget the exceptions, e.g. the better brain outcomes in cardiac arrest and stroke patients, and, of course, treatment of heat stroke and the other hyperthermia syndromes.
