Elderly fever needs to be handled with caution

Elderly fever needs to be handled with caution

When the elderly have a fever or a sudden change in functional status, the cause must be identified as soon as possible and the correct treatment should be given as soon as possible.

Because the researchers have found through a large number of clinical observations, the elderly may not have obvious fever or fever when they have infectious diseases, so they are easily missed and delay treatment, which leads to an increase in complications and mortality in the elderly.

If the elderly have fever, they often indicate a serious infection.

  Although the average maximum and maximum body temperature and minimum body temperature of healthy elderly people are not much different from those of young people, the basal body temperature of frail elderly people is lower than that of healthy young people.

The average morning oral temperature of the elderly is 36.

7 ° C, anus temperature 37.


The definition of fever in the elderly is: oral temperature continues, 37.

2C, anus temperature continues, 37.

5 ° C.

Absolutely use any thermometer to measure at any location (such as underarm temperature) as long as the temperature is higher than the basal body temperature, 1.

3C indicates fever.

However, it should be remembered that once the elderly have noticed a dramatic change in their functional status, there is indeed no fever, and it is necessary to consider the possibility of an acute infection.

  The characteristics of fever in the elderly are still: when the elderly suffer from endocarditis, pneumonia, etc., the fever is lower than that of young people, and even a large proportion of patients with acute cholecystitis, appendicitis, perforation and perforation, the body temperature is lower than 37.


In the elderly with severe infections, about 20%-30% do not have fever or fever, which is often a poor prognosis.

The detailed mechanism of delayed fever in the elderly is unclear and may be related to age.

  The fever that most elderly people are looking for can be diagnosed and cured.

According to some data, 25%-35% of the elderly have infections, and the probability of tuberculosis infection is much higher than that of younger ones; connective tissue diseases account for 25%-31% (such as rheumatoid arthritis, spinal arteritis, etc.)Malignant tumors account for 12%-23%.

Therefore, the elderly should find out the cause of fever as soon as possible in order to obtain timely and correct treatment.
