For what purposes are measured rectal temperature
Rectal (basal) temperature is measured to study the function of the ovaries. During the menstrual cycle the hormones in a woman's body changes. In the first phase of the monthly cycle rectal temperature is from 36.5 to 36.8 per OS, the second - from 37,0 to 37.2 OC. Its decline in the period of ovulation. In the second phase of the cycle the increase in rectal temperature occurs due to changes in the hormonal composition of blood and evidence of exit into the abdominal cavity capable of fertilizing an egg. Days before you ovulate and are most fertile. Making and analyzing graphs rectal temperature can reveal the optimal days for sexual intercourse to plan a pregnancy.
Rectal temperature measurement is carried out daily, without interruption during menstruation, for at least three menstrual cycles. It should be determined at the same time, the difference should not be more than 30 minutes. The rectal temperature should be measured immediately after waking up. You can't get out of bed, it is impossible to do sharp movements. Cooked in the evening the thermometer should be carefully inserted into the anus. Time of temperature measurement should be about the same and be 5-10 minutes.
After extracting thermometer need immediately to record his testimony.
What factors can affect rectal temperature
When measuring the rectal temperature should pay attention to the circumstances that can change the rate. It can be disease with the General rise in temperature, diarrhea, local inflammation (fissure of the rectum, sore, inflamed node of the rectum), boils or abscesses of the buttocks and the inflammation of the wounds on his legs. On the magnitude of rectal temperature can also affect a small time of sleep (less than five hours before the measurement), the measurement at unusual times, sleep in changed temperature conditions (too hot or too cold), sex, admission on the eve of alcohol or any drugs. The use of vaginal plugs usually do not affect the indicator. When recording values of the rectal temperature, it should be noted probable cause of the deviations.
Analysis of the chart basal temperature is of great importance for the diagnosis of infertility or pregnancy.
The use of these graphics rectal temperature suggests or diagnosing lack of ovulation (when the temperature is monotonic, below 37,0 OS), endometriosis or chronic endometritis (if periods are at a temperature above 37,0 OS), failure of function of the corpus luteum (if the basal temperature is increased after the presumed ovulation, lifting it lasts no more than 5-7 days), acute inflammation (if in any phase of the cycle, the basal temperature is much higher 37,0 OS).
