It starts in the brain
To really understand what is fever, you need to know the hypothalamus. The hypothalamus is the brain center. Think of it as the body’s thermostat, the device is in the walls of many houses and used for adjusting the temperature of the heating and / or air conditioning. The hypothalamus knows what temperature should be the body of a person and sends messages to the body to be set and maintained at that temperature.
The body temperature of most humans is around 37 ° C (98.6 ° Fahrenheit). Some people will have a normal temperature a little higher, others will have it a little lower.
The body temperature of most people also varies slightly during the day: it will be a little lower in the morning and a little higher in the evening.
What is fever?
Fever is not a disease but the body’s response to an abnormal situation. In children, most commonly it is caused by an infection, so it is not so much control fever and properly diagnose and treat the infection. There are even plenty of evidence showing that moderate fever facilitates the body’s defense mechanisms against infections.
Other causes of fever can be dehydration, excess clothing, especially in newborns, drug reaction, allergy, and very occasionally, some tumors.
It is believed that a person has:
- Hypothermia: When the temperature is below 35.0 º C.
- Sub-fever or feverishness: less than 37.5 º C.
- Mild fever: mens of 38 ° C.
- Mild fever: 38 – 39 º C.
- High fever: 40 º C.
- Hyperthermia: 41 º C.
What is the normal temperature?
A normal oral temperature is about 98.6 ° F (37.0 ° C). Rectal temperatures are 0.5 ° C higher and axillary 0.5 ° C lower than oral. A characteristic of some children is their tendency to experience rapid temperature elevation, with the associated risk of seizures, children under 3 years are more susceptible to seizures.
How is the temperature?
First, we must remember that there are thermometers for rectal use and axillary or oral use. Although all used to be used in any of these sites, the key difference is security, because the rectal bulb are shorter and thicker, which decreases the risk of injury or rupture of the thermometer. Unfortunately the tapes to the skin are notoriously unreliable, especially in young children.
It is important that before taking the temperature does not have eaten hot or cold foods if oral measurement and dried where axillary skin.
Recently it has become fashionable thermometers that measure temperature in the ear. Although they are very practical, have two major drawbacks, cost and lack of sensitivity, so it is very easy to get wrong. It is also advisable not to use. Mercury is a toxin to the environment and you do not want to risk exposing your family to it. If you have a mercury thermometer at home, you should remove it and use a digital thermometer.
In oral temperature, the thermometer should be placed under the tongue in the sublingual pouch and continued for 3 minutes. In the axillary temperature, place it under his arm at the Center of the axilla and stuck to the skin for 4 minutes. and rectal temperature Lubica not tip well over 2.5 cm into the rectum to hold the thermometer for 1 minute.
Never leave your child alone while taking his temperature.
After you finish using the thermometer, wash in cold water and soap.
What to do?
First, keep the child with very cool clothes, which promotes heat loss, not anxious about fever, remember that it may be useful to the body temperature measured with a thermometer, not your hand.
If the temperature is below 38.5 º C, and the child does not feel pain, it’s best to just observe. If the temperature is higher and lower it is considered necessary to make the child feel better, eat more, is calmer, or to decrease the risk of seizure with fever, you can use sponge baths, wetting the skin of the extremities and trunk with water at the time or slightly warm. If you use very cold water can cause more chill and thereby obtain the opposite effect.
If a child has high fever, most likely, the doctor told his parents that give an antipyretic, is a medicine to reduce fever. The two most recommended antipyretics are acetaminophen and ibuprofen. Both block the chemicals that tell the hypothalamus to raise body temperature. Children should never take acetylsalicylic acid (the active ingredient in aspirin) to treat fever because it can cause an illness called Reye syndrome. Reye’s syndrome is a serious illness that can cause death. . .
1. Never use ice water enemas for the risk of water intoxication. 2. Never use alcohol baths as this can be absorbed through the skin and cause serious injury. You should drink plenty of fluids. This is important because when the body heats up, it’s easy to become dehydrated, ie it loses too much water. Plenty of choice for well-hydrated juice, water, sports drinks, soup, jelly.
And most importantly talk to your doctor, because the fever is indicative that there is a problem and your child should be examined
