What are the classifications of fever? What are the types of fever?

Thermal types are classified as residual heat, relaxation fever, intermittent fever, and irregular fever.

The classification and characteristics of the thermal type are as follows:

Residual fever: The body temperature continues to rise to about 1 for several days or weeks, and does not fluctuate more than 1 in 24 hours. It is common in typhoid fever, pneumococcal pneumonia, etc.

Relaxation fever: the body temperature is above but fluctuates widely, the difference in body temperature is more than 1 in 24 hours, and the minimum body temperature is still above the normal level. Common in sepsis, rheumatic fever, etc.

Summary tip: It is necessary to pay attention to distinguish between residual fever and relaxation fever, the meaning of retention is continuous stay, all 24 hours of body temperature continues to stay in a high temperature state, the body temperature fluctuation is not large, no more than 1, and the meaning of relaxation fever is relaxation and tension, high and low, so the fluctuation is relatively large, more than 1.

Intermittent fever: high fever alternates with normal body temperature, with a sudden rise in body temperature above 39 for a few hours or longer, then a rapid drop to normal, followed by a break of hours or days, followed by a recurrence. It is commonly seen in malaria, etc.

Irregular heat: The body temperature changes irregularly over a 24-hour period. It is common in epidemics, tumor fever, etc.

Precautions: Different febrile diseases have their own corresponding heat types, and according to the different heat types, it is helpful for the diagnosis and differential diagnosis of fever**. But it must be noted:

Infection can be controlled in a timely manner due to the widespread use of antibiotics, or by the use of antipyretics or glucocorticoids, which can make the characteristic thermal pattern of some diseases atypical or irregular.

The fever type is also related to the strength of the individual response, for example, the elderly may have a low-grade fever or no fever in the case of shock pneumonia, but do not have the typical fever of pneumonia.

There are several types of fever: Residual fever. The body temperature is usually above 39, and the daily fluctuation range does not exceed L.

Seen in typhoid fever, typhus, lobar pneumonia, etc.; Relaxation fever. The body temperature is above 39, but the daily fluctuation is very large, and the body temperature can drop below normal temperature, also known as wasting fever or septicemia fever. seen in sepsis, sepsis, abscesses, etc.; Intermittent heat.

Febrile and afebrile phases alternate. Seen in malaria, lymphoma, etc.; Regression fever. The high fever rises suddenly, lasts for a few days and then recedes suddenly, and the interval is no fever for several days, and the high fever reappears, which can be repeated several times.

seen in relapsing fever; Brucellosis. The heat gradually rises, peaks and then gradually decreases, then rises and falls again, in a wavy shape, seen in brucellosis; Doublet fever. The heat rises and falls, rises and falls again in a day, and the difference between each rise and fall is about 1.

seen in gram-negative bacillary sepsis, kala-azar, acute schistosomiasis; Irregular heat. The daily heat varies from day to day and fluctuates irregularly. It is seen in amoebic liver abscess, etc.

According to the length of the fever fever process, it can be divided into short-term fever and long-term fever. Short-term fever is more common in various acute infectious diseases, such as measles, chickenpox, rubella, scarlet fever and other exanthematous acute infectious diseases, as well as upper respiratory tract infections, epidemics, hepatitis, dysentery, some bacterial food poisoning, urinary tract infections, etc. Sunstroke.

Non-infectious fevers such as drug fever and heteroprotein fever are all short-term fevers. Short-term fever is mostly about a week, but there are also cases as short as 1 to 2 days. Long-term fever refers to those with a fever duration of more than 2 weeks, which is seen in typhoid, tuberculosis, and sepsis.

Infective endocarditis, leukemia, malignant tumors.

connective tissue diseases, etc.

Fever is often accompanied by other symptoms. If accompanied by headache.

When vomiting, coma and other mental changes, central nervous system infections should be considered, such as Japanese encephalitis, various bacterial meningitis, viral meningitis, fungal meningitis, etc.; If it is accompanied by cough, phlegm, chest pain or shortness of breath, lung, pleural and other diseases should be considered; If it is accompanied by diarrhea, there is a possibility of intestinal infections such as bacillary dysentery and bacterial food poisoning; If abdominal pain is present, hepatobiliary infection should be considered; If it is accompanied by symptoms such as low back pain, frequent urination, urgency, and painful urination, it indicates the presence of urinary tract infection.

1.Residual fever: refers to a significant increase in body temperature of 39 40 or above, and the difference in body temperature fluctuation within 24 hours is not more than 1.

2.Relaxation fever: refers to the type of body temperature curve that fluctuates by more than 2 in a 24-hour period, but the lowest point does not reach the normal level.

3.Intermittent fever: A sudden rise in body temperature that lasts for several hours and then rapidly drops to normal levels, and periods without fever can last for 1 to several days, alternating between periods of high fever and periods of absence of fever.

4.Relapsing fever: refers to a type of body temperature curve in which a rapidly rising high fever persists for a few days and then plummets spontaneously, but then reappears a few days later.

5.Undulating fever: refers to a fever type in which the body temperature rises to 39 or above, gradually decreases after a few days, and then regenerates for a few days.

6.Irregular heat: refers to the heat type of fever in which the body temperature curve of a febrile patient does not have a certain regularity.

There are many types of fever, and it has a lot to do with the disease that causes it. Common types of fever are: relaxation fever, residual fever, undulating fever, bimodal fever, low-grade fever, intermittent fever, etc.

Infection is the most common cause of fever. Therefore, when fever occurs, it is necessary to pay attention to the presence of infectious lesions. It is also necessary to take more physical cooling, drink more water, try to avoid excessive intake of antipyretic drugs, avoid affecting the judgment of the condition, and pay attention to strengthening nutrition.

The body temperature of a normal person is regulated by the thermoregulatory center, and the heat production and heat dissipation processes are dynamically balanced through nervous and humoral factors, keeping the body temperature within a relatively constant range. Fever refers to the situation in which the pyrogen directly acts on the thermoregulatory center, the body temperature center is dysfunctional, or the excessive heat production and reduced heat dissipation caused by various reasons, resulting in an increase in body temperature beyond the normal range.

Normal body temperature varies slightly from person to person and is influenced by many factors (time, season, environment, menstruation, etc.). Generally 36 37, to determine whether there is a fever, it is best to compare it with your usual body temperature under the same conditions. If you do not know your original body temperature, your armpit temperature (10 minutes of detection) exceeds that of a fever.

In order to talk about the type of non-land or fever, the file is (c) aAcute fever.

b.Chronic fever.

c.Short-term fever.

d.Long-term fever.

Yes c, short-term fever is not a type of fever.
