Defevering – treatment, effects and risks

Defever

In medicine, a body temperature of over 38 degrees is referred to as fever . If the curve rises above 39.5 degrees, then there is talk of a high fever. Defevering is a measure that serves to counteract this symptom .

What is defevering?

A person’s body temperature fluctuates throughout the day. It is regulated in a part of the diencephalon called the hypothalamus . Fever releases the body’s own defences. This stimulates the leukocytes (white blood cells) to work harder. An increased release of interferon also sets in and both activities in the hypothalamus bring about the natural defecation.

A warm meal or strenuous activities such as sport sometimes cause the temperature to rise by around 2 degrees. Elderly people and small children also often have an increased body temperature if their fluid balance is not in order. In this case, the fever is relieved by the administration of drinks. If this is not possible orally, a stay in a hospital is necessary. Those affected are given the fluid they need by administering IV fluids. A simple saline solution without the addition of medication then takes care of the fever.

Function, effect & goals

Even if fever is not a disease in its own right, it can cause serious damage to the body. Defevering is therefore vital. If the high body temperature in infants is not treated in time, their body reacts with convulsions, which can very quickly lead to death.

Febrile seizures are dangerous and can be prevented by giving plenty of fluids. Even adults with a very high fever show signs of convulsions. It can also be observed that they suffer from perceptual disturbances, comparable to delirium . Sometimes this leads to permanent brain damage.

A mild fever can initially be curbed with simple home remedies. Calf wraps have been a recipe for high body temperature for many years. For this purpose, a towel is soaked in cold water and placed on the affected person’s lower legs. In many cases, this causes the body temperature to drop. However, defervescence must not be too rapid. The circulatory system cannot tolerate this and a collapse would be the result.

Defevering is also done with medication under medical supervision. The specialist administers a suitable medication that reduces the fever. In doing so, he makes sure that he is also fighting the triggering factor. Both viruses and bacteria can be responsible for fever. The examination of the urine and/or the blood provides information.

A blood sedimentation shows within minutes whether an inflammation has formed in the body and whether this is the reason for the fever. Checking vital functions is a routine part of defebration under medical supervision. In people who are permanently bedridden, the stressed skin areas tend to form necrosis . This means that the skin is insufficiently supplied with blood and dies off. In these cases, the fever is removed by removing the necrotic areas.

Risks, side effects & dangers

Chills are a symptom of fever. Even in great heat, the affected person suddenly begins to freeze. Neither a thick blanket, nor hot tea, nor the hot-water bottle prevent his whole body from trembling. This is because muscle contractions generate heat. Due to the increased temperature, this bodily function is restricted and the person freezes.

In such a case, defervescence must be provided quickly. Antipyretics and calf wraps are part of the emergency measures. If there is no noticeable improvement in condition, medical advice is required. This also applies if the fever breaks down too quickly. If the high body temperature falls within a short period of time, this puts a great strain on the cardiovascular system and must be treated by a doctor. This acute emergency is also known as a crisis.

Defevering should not take place without examining the person concerned. It is determined whether bacteria or viruses are the causes of the rise in temperature. A tumor or malignant lymph node inflammation can also be responsible for the fever. The administration of antibiotics or other antipyretic drugs is therefore only possible after the blood and urine have been tested.

In lytic fever, the temperature decreases slowly. The time scale here is around 24 hours. It is only possible under medical supervision. There are different approaches under the technical term lysis . The goal is the same for everyone: bacteria, viruses or obstacles to drainage are dissolved or destroyed by suitable medication.

Obstacles to drainage within the body can be blood clots or stones. The removal of kidney and gallstones therefore automatically leads to the patient’s fever defecation.

However, self-treatment with medicines that are still left in the medicine cabinet can also have serious consequences. This applies, for example, to the careless use of antibiotics. MRSA (methicillin-resistant Staphylococcus aureus), also known under the term ‘multi-resistant germs’, arose, among other things, from the fact that antibiotics were taken too frequently and imprudently. There are now germs that are immune to any medication, which is why some patients cannot be treated. Defevering is important if the fever curve is too high for several days, the administration of penicillinis therefore not fundamentally necessary and always requires a prior examination.
