The child has a fever and is shivering

When children have a fever, they will feel that they have some other symptoms, such as shaking hands. This is very common. Then when it happens, they must take some medicines with antipyretic effects, and they need to take corresponding drug treatment according to the exact temperature of their specific fever. In this way, they can prescribe the right medicine and avoid misdiagnosis during the medication process.

1. Fever degree classification (axillary table)

(1) Low fever 37.5～38.0℃;

(2) moderate fever 38.1-39.0°C;

(3) High fever 39.1～40.0℃;

(4) Hyperthermia above 40°C.

2. According to the duration of fever, it can be divided into

(1) Short-term fever lasting less than 2 weeks, often accompanied by local symptoms and signs;

(2) Long-term fever lasting ≥ 2 weeks, with some patients having no obvious symptoms or signs;

(3) Fever of unknown origin (FUO): Fever persists or is intermittent for more than 3 weeks and cannot be diagnosed through physical examination and routine auxiliary examinations;

(4) Chronic low-grade fever: Low-grade fever lasts for more than one month.

3. Common fever types

Children's fever patterns are not as typical as those in adults. In recent years, due to the widespread use of antibiotics and the application of corticosteroids, fever patterns have changed, and the significance of fever patterns for differential diagnosis of diseases has been affected.

(1) Persistent fever with persistent fever and small fluctuations in body temperature, generally not exceeding 0.6°C;

(2) Remittent fever: body temperature fluctuates by 2 to 3°C but does not return to normal;

(3) Intermittent fever returns to normal for at least 24 hours before fever reappears;

(4) Bimodal fever: There are two peaks of fever within 24 hours;

(5) Recurrent or relapsing fever with multiple episodes of fever, each lasting several days, with normal body temperature for 1 to several days between episodes;

(6) Irregular thermal patterns have no definite pattern.

4. Stages of fever

During the fever process, due to the constant changes in the contradiction between heat generation and heat dissipation, fever can generally be divided into four stages:

(1) Many febrile diseases may not have any symptoms during the prodromal phase. The duration of symptoms in this stage varies according to the specific circumstances of the febrile disease, and is mainly manifested by general discomfort, fatigue, loss of appetite, emotional instability, and low fever. Some exanthematous diseases may have a prodromal rash before the appearance of the systemic rash. For example, during the prodromal stage of measles, Kleinberg spots may appear on the oral mucosa.

(2) The temperature rise period is characterized by high heat production and low heat dissipation, so heat production is dominant and the body temperature rises. Symptoms include pale, dry, sweat-free skin, goose bumps, and a cold feeling to the touch. If chills occur, it indicates that a high fever will occur. Young children may experience convulsions at this time. During the chills, the body temperature is mostly above 38°C, and most of the time it reaches the peak of high fever within a few hours, such as malaria, lobar pneumonia, sepsis, drug-induced fever, etc. The above are those with sudden rise in body temperature.

A gradual rise in body temperature refers to a fever that starts with a low fever and gradually rises from a low fever to a high fever within a few days. This is called a gradual fever. Those with gradual onset often have prodromal symptoms, most of whom do not have chills, but sometimes they may feel cold, like atypical typhoid fever. Some people present with a sudden rise in fever, which may be caused by a low fever that is ignored. In addition, the body temperature of diseases such as tuberculosis is gradually rising.
