Reassurance for parents about febrile convulsions The signs and symptoms of a febrile convulsion can be very frightening to parents. Important things to remember include: Children suffer no pain or discomfort during a fit. A febrile convulsion is not epilepsy. No regular drugs are needed. A short-lived fit will not cause brain damage.

Even a long fit almost never causes harm. Children who have had a febrile convulsion grow up healthy. If you have concerns or questions, contact your doctor. In an emergency, take your child to the nearest hospital emergency department. There is a medication called Midazolam that is sometimes recommended for children who have a history of febrile convulsions lasting longer than 5 minutes.

Most children do not require this medication. If you would like more information about this treatment, you should talk with your doctor. Causes of febrile convulsions Febrile convulsions only happen when there is a rise in body temperature. Treatment for a fever Fever is a normal response to infection and is usually harmless. If your child has a fever, suggestions include: Keep them cool by not overdressing them or having their room too hot.

Give them plenty to drink. It is best to give small, frequent drinks of water. Fever is a natural, adaptive response of the body, to physiological stress. Fever can be caused by a vast range of conditions, both infectious and non-infectious.

This results in a controlled increase of the overall body temperature. This change in the set-point is mediated by the action of cellular messengers, known as pyrogens, on the hypothalamus. Pyrogens can either be endogenous e. IL1, IL6 or exogenous e. For instance, hyperthermia could be caused by strenuous exercise in a hot environment or due to excess heat production in diseases such as pheochromocytoma a rare form of tumor in the adrenal gland.

As a result, hyperthermias do not respond to anti-pyretic drugs, such as Aspirin or Acetaminophen, like fevers do. Serious illnesses like sepsis, are usually accompanied by very high fevers even up to In such cases, it is absolutely essential to rule out hyperthermia. No matter how high the fever, administering antipyretics usually results in a slight drop in temperature.

Because fevers are centrally controlled, there is usually some diurnal variation - i. However, there is no such variation observed in the case of hyperthermia. Fevers are a natural, protective response of the body and are often innocuous. A novel biologic function of serum amyloid A-induction of T lymphocyte migration and adhesion. Lab Invest.
