Temperature curves

Temperature curves - graphic representation of the temperature fluctuations during the daily measurement. Temperature curves give a clear picture of the nature of fever (see)have often significant diagnostic and prognostic value.
Types of curves highlight the following types of fever.
1. At constant fever (febris continua) body temperature is usually high, within 39C, held for a few days or weeks with fluctuations within 1 degree. Occurs in acute infectious diseases: typhoid fever, lobar pneumonia, and other (Fig. 1).
2. Laxative, or relapsing fever (febris remittens) is characterized by significant daily fluctuations in body temperature (up to 2 degrees or more), found at purulent diseases (Fig. 2).
3. Intermittent, or intermittently, fever (febris intermittens) is characterized by sharp rise of body temperature up to 39-40 degrees and more and recession in the short term to normal and even subnormal numbers; in 1-2-3 day the same rise and fall again. Typical for malaria (Fig. 3).
4. Hectic, or debilitating, fever (febris hectica) characterized by large daily fluctuations of temperature of the body (more than 3 degrees) and a sharp drop it to normal and subnormal numbers, and fluctuations of temperature greater than that with relapsing fever; observed in septic conditions and severe forms of TB (Fig. 4).
5. Recurrent fever (febris recurrens). The body temperature rises up to high numbers, rests on these values few days, then decreases to normal. Some time later the fever comes back again followed by remission (febrile seizures may occur, 4-5). This type of fever typical of some of spirochetosis (relapsing fever and other) (Fig. 5).
6. Undulating fever (febris undulans). Gradual day-to-day temperature increase with a similar reduction nature. There may be several waves of raising and lowering the temperature differs from recurrent fever gradual increase and losing temperature. Occurs when brucellosis and other diseases (Fig. 6).
7. Twisted fever (febris in versa). Morning temperatures above the evening, meets with tuberculosis, protracted sepsis, prognostically unfavorable.
8. Irregular fever occurs most often. Daily fluctuations of body temperature varied, the duration is not determined. Observed at rheumatism, pneumonia, dysentery, influenza (Fig. 7).
Temperature curves there are 3 periods of fever.
1. The initial period, or a stage of rise of temperature (stadium incrementi). Depending on the nature of the disease, this period may be very short and measured in hours, usually accompanied by fever (for example, malaria, lobar pneumonia), or stretch out on a long term of up to several days (for example, typhoid fever).
2. Stage height of fever (fastigium or acme). Lasts from several hours to several days.
3. Stage of temperature reduction. The rapid drop in temperature is called the crisis (malaria, lobar pneumonia, typhus; Fig. 8); gradual decrease called lysis (typhoid and others; Fig. 9).the species temperature curves

Figure 1-9. Different types of temperature curves. Figure 1-7 Fever: Fig. 1 - permanent; Fig. 2 - laxative; Fig. 3 - intermittent; Fig. 4. - hectic; Fig. 5 - reflexive; figure 6 - wavy; Fig. 7 - wrong. Fig. 8. A crisis. Fig. 9. Lysis.

At the critical temperature decrease is observed profuse sweating, often falling vascular tone and sharp weakness. Cm. also the body Temperature, Temperature sheet.
