What is a feve

Normal body temperature in a certain range. General axillary temperature of 36-37.4 ℃, so it has often been the temperature above 37.5 ℃ for fever. And further divided into ,37.5-38 ℃ for low-grade fever ,38.1-39 ℃ to moderate fever ,39-40 .4 ℃ high fever, more than 40.5 ℃ for the ultra-high heat.
Normal children more vulnerable to fluctuations in body temperature, infection, environment and movement and other factors could lead to changes in body temperature in children. Children with elevated body temperature rise is not necessarily abnormal, that is to say the higher temperature is not necessarily the heat. If short-term fluctuations in temperature, but the whole body in good condition and no other abnormal performance should not be considered as children in the fever, may be generated by the following non-disease factors.
Normal body temperature can be increased after exercise. Children in the crying, feeding and other normal physiological activity will increase body temperature. Under normal circumstances, the body temperature does not rise too high, mostly between 37.5-38.0 ℃. Temperature rise is due to crying, feeding and other normal physiological muscle activity resulted in more heat. These reasons lead to increased body temperature, cessation of movement will be returned to normal levels quickly. Encounter these situations, parents can continue to observe the temperature changes in children generally do not need any treatment.
Abnormally high body temperature of the so-called referring to the heating temperature not only increased, but also at the same time due to illness caused by the existence of other abnormalities, such as: pale, breathing accelerated, emotional instability, nausea, vomiting, diarrhea, a skin rash. Because of individual differences in children and lead to different diseases, fever, after the performance and there is great difference. For example, with pneumonia, fever and some children are not high, some children can heat up to 39-40 ℃; and if the sense of sustainable heat 2 to 3 days and sustainable for several weeks sepsis. There are acute onset of fever there is relief, and some first heat followed by chill; some heat but very cold extremities and forehead, so his hands and forehead touching the limbs can not easily be detected and sometimes fever, chest and abdomen and can feel the touch fever in children.
In addition, due to brain disease, lesions of central temperature regulation has been violated, nerve conduction system or heat-related dysfunction of tissues and organs (such as hyperthyroidism) or too high temperature of the external environment (eg heat stroke) and serious skin injury Thermal effects of features such as skin, the body's temperature will rise, sometimes up to a very high level. This phenomenon is not a fever, but overheating.
Parents should be noted that when the body temperature of children over the normal range, particularly when there is high fever, do not panic. Should first determine the accuracy of temperature measurement, but also to give serious consideration to the reasons causing the body temperature increased, as necessary, timely diagnosis and treatment of children to go to the hospital in order to avoid delays in diagnosis and treatment of disease.
