How do you deal with low fever in children? Some parents don't pay enough attention to low fever, think it is not necessary to go to the hospital, and missed the best time to treat many diseases. Another kind of parents is more nervous. They think that once the child's temperature exceeds 37 degrees, it is a very serious problem. Let's detail the knowledge about low fever from the perspective of a professional children's doctor.
The basal body temperature of normal children is about 36.9 to 37.5 degrees Celsius, (the body temperature here refers to the temperature of the underarms). Generally, when the body temperature exceeds the basal body temperature, it can be considered as fever. Body temperature fluctuates around 37.5 to 38 degrees Celsius which can be considered low fever. When the body temperature reaches above 39 degrees Celsius, it can be considered as high fever.
Because many children (especially infants and young kids) do not cooperate when measuring body temperature, parents now tend to use ear thermometers to measure the temperature of their babies. The temperature measured by the ear thermometer is based on the above basal body temperature, which we generally call the core body temperature, so the temperature measured by the ear thermometer is higher than 37.8 degrees Celsius, which can be considered a fever. In addition, the temperature difference between the ear thermometer and the armpit is about 0.3 to 0.5 degrees Celsius.
Long-term low fever refers to a temperature of about 37.5 to 38 degrees Celsius in children, which lasts for more than two weeks, and is accompanied by symptoms of loss of appetite, fatigue, rash, and joint pain. Long-term low fever needs to be taken seriously by parents. It is often a precursor to some infectious diseases, blood or immune system diseases.
According to the cause of low heat, we can simply divide low heat into: non-organic low heat and organic low heat.
It means that there is no actual change in organ function except fever, such as physiological low fever and seasonal low fever.
1. Physiological hypothermia: Children's body temperature fluctuates between day and night, but this fluctuation generally does not exceed about 1 ° C. Most physiological hypothermia does not require treatment, and there are no signs in the whole body.
The use of antipyretic drugs does not have a significant effect when the fever is low, and the fever can resolve on its own. The temperature of premature babies, newborns, and babies under one year of age is more susceptible to fluctuations, and is usually not called a pathological phenomenon if there are no other accompanying symptoms.
2. Seasonal hypothermia: It occurs mostly in the summer season, and it manifests as long-term hypothermia, with thirst, polyuria, and fatigue. It is more common in fragile children from six months to three years of age, which can last for one to three months.
When the temperature improves, the children body temperature drops to normal. There is currently no effective treatment and preventive measures for this disease. Generally, it is recommended to eat a reasonable diet and go to less densely populated areas to avoid causing infections.
Children with chronic organic low fever, chronic infections are more common. Chronic infectious hypothermia is mainly due to the stimulation of pathogenic microorganisms, which causes febrile reactions in children.
Low fever caused by tuberculosis is the most common of various chronic infections, followed by tonsillitis, otitis media, inflammation of the urinary system or chronic infection, sepsis, rickettsial infection, etc. these are may cause chronic low fever. Therefore, treatment is usually directed against the pathogen that caused the infection, and we need take corresponding treatment measures.
For children with low fever, prevention is the key. Parents should pay attention to the child's physical condition, and prepare ear thermometers, stethoscopes, and commonly used drugs at home.
