Recent United States University of California medical scientists made warned: when the heating or when there is a quick change of function in the elderly, must as soon as possible a clear cause, given proper treatment as soon as possible.Because researchers with a lot of clinical observation found that due to infectious diseases in the elderly, not obvious or not to heat fever, therefore easily missed and delayed treatment, so that the complications and mortality are higher in the elderly.If the elderly once fever, often prompting serious infection.
While the average maximum temperature and minimum temperature in healthy elderly people and young people little difference, but the basic body temperature below the healthy young man of frail older persons.Average oral temperature 36.7 ° c in the early morning of the elderly, anal temperature 37.3C.Fever is defined in the elderly: oral temperature, 37.2C, anal temperature continued, 37.5 ℃.Regardless of any thermometers on any part (such as body temperature under the armpit) measurements, as long as the temperature than base temperature rises, 1.3C that indicates there is a fever.However be remembered that, as long as the function is found in the elderly drastic changes, with or without fever, are considered likely to have an acute infection.
Characteristics of fever is also in the elderly: when you risk of endocarditis, pneumonia in the elderly, low fever than young people, or even a significant share of elderly patients with acute cholecystitis and appendicitis, gastrointestinal perforation, body temperature less than 37.5C.In severe infections in the elderly, also 30% heat or heat-induced slow, this is often the prognosis is poor performance.Elderly people detailed mechanism of slow fever is not clear and may be associated with age-related.
Most elderly people find this fever can be diagnosed and cured.Information: causes of fever 25%-five for infection in the elderly, tuberculosis infection is much higher than the probability of young into; 25%-cent connective tissue diseases (such as rheumatoid arthritis, such as temporal arteritis), cancer accounted for 12% per cent.Therefore, the fever as soon as possible to identify its cause in the elderly, in order to have timely and correct treatment.
