It is a sign that indicates a probable pregnancy.
The signs are those that the doctor usually observes when examining the patient during pregnancy.
Hegar’s sign was repeatedly demonstrated and described by Ernst Ludwig Alfred Hegar, a German gynecologist, in 1895. Hegar credited Reinl, one of his assistants, who originally described this sign in 1884.
The diagnosis of uterine pregnancy is easily made after the first two months of gestation in the average case, and in experienced hands a near-positive diagnosis is often possible during the first eight weeks of pregnancy.
It is often important to make an early diagnosis between normal pregnancy and various pathological conditions, particularly fibromyomas of the uterus, ectopic pregnancy, inflammatory tumors, and ovarian cystoma.
The art of classical obstetrics
With the advent of ultrasound and specific urine and blood tests, diagnosing pregnancy is quite simple. But there is a certain kind of romance in the history of pregnancy diagnosis before these modern aids were in common use.
Doctors used to be trained differently, using judgment and diagnostic skills that seem outdated today.
Today, we can clinically pinpoint ovulation and conception, so current obstetric books do not focus on diagnostic measures that are based on the signs and symptoms of yesteryear.
When early pregnancy diagnosis was an art, there was a certain linkage phenomenon that occurred with following the conditions described below.
In earlier unsophisticated times, many women were unable to obtain a diagnosis of their “delicate condition” until mid-pregnancy.
The signs and symptoms described below were actually the practice of medicine back then, but now most of them are historical in origin.
However, despite its clinical importance, pregnancy is a beautiful experience for mammals; And although the science of obstetrics has improved pregnancy, the beauty of the art of medicine has been lost.
In the “old days”, around the year 1960 (last century) The diagnoses of the “old days” were grouped into three classifications:
Presumptive evidence of pregnancy mainly things perceived by the woman:
- Cessation of menstruation: Other things can cause this, but pregnancy and menopause top the list of possible.
- Breast changes: tenderness at first, then the nipples become darker and larger. Subsequently, discharge of colostrum (precursor of milk).
- Abdominal stretch marks
- Greater pigmentation. The “black line,” or black line, runs down the center of the abdomen and usually fades after pregnancy.
- Increased urination, due to the pressure of the growing uterus on the bladder.
Physical signs were often named after the people who discovered them and include:
- Jacquemier’s sign.
- Hegar’s sign.
- Osiander sign.
All of these signs include uterine changes, abdominal changes, cervical changes, basal body temperature, positive pregnancy test by a doctor, and fetal palpation.
Hegar’s sign is a non-sensitive indication of pregnancy in women; its absence does not exclude pregnancy.
It refers to the characteristics of the cervix and uterine isthmus. It has been shown to soften the consistency of the uterus, and the uterus and cervix appear to be two separate regions.
This is a softening of the lower uterine segment just above the cervix. When the uterus is compressed when examining the fingers, the wall feels that the tissue paper is thin.
The doctor will use the bimanual maneuver simultaneously (abdominal and vaginal) and cause the uterus to tilt forward.
Hegar’s sign is seen in the sixth to eighth week of pregnancy. Hegar’s sign is more difficult to recognize in multiparous women.
The probable sign of Hegar is a bimanual examination with two fingers in the anterior puncture and the fingers of the other hand in the abdomen behind the uterus, the inner and outer fingers can be approximated due to the fact that the lower segment is soft and empty.
