Prenatal signs

Introduction Before the birth of the childbirth, there is a symptom indicating that the labor will be soon to be delivered, which is called a threatened labor. Including: false labor, fetal decline, see red, is a relatively reliable sign of childbirth is about to begin.

Cause

1, the bottom of the palace decline

The height of the fundus began to decline, reducing the pressure on the diaphragm. Pregnant women felt less difficulty in breathing, the pressure of the stomach disappeared, and the appetite increased.

2, abdominal pain

The lowering of the fetal head increases the pressure on the pelvis, and the feeling of the backache is more and more obvious.

3, the number of large, urination increased

The fetus is lowered, the bladder and rectum are compressed, so that there is still urine in the urine after urination, and there is still an anal bulge after the stool.

4, increased secretions

Increased secretions from the cervix and vagina.

5, fetal movement reduction

Fetal movements are not so obvious at this time, don't feel uneasy about this, because the fetal position is relatively fixed. However, if the fetal movement is reduced significantly or if the fetal movement is still not felt for 12 hours, you should immediately get a doctor's diagnosis.

6, weight gain stops

Pregnant women can experience an increase in weight loss, and sometimes even weight loss, which can be a sign of fetal maturity.

7, the uterus has frequent, irregular pain

That is, fake contractions. From the 28th week of pregnancy, false abdominal contractions often occur in the abdomen. If the pregnant woman is standing or sitting in the same position for a long time, it will feel the hardening of the abdomen. This is a false contraction, which is characterized by irregular time and degree of weakness. Before labor, due to the compression of the lower part of the uterus caused by the decline of the fetal head, the situation of false contractions will become more and more frequent. If the contractions are shortened to 5 to 10 minutes, they should be diagnosed immediately by the doctor.

8, see red

The leucorrhea containing blood from the vagina is called "see red." Usually go to the hospital for examination within a few hours of seeing red. But sometimes after seeing red, it still has to wait for 1-2 days, sometimes only after a few days, regular uterine contractions begin to appear.

1. Clinical calculation: Learn more about the previous menstrual cycle, ask about the last menstrual date, the start of early pregnancy reaction and the start time of fetal movement; according to the gynecological examination during early pregnancy, the size of the uterus is consistent with the menstrual month; refer to the current pubic uterus length and The abdominal circumference is calculated as the gestational age.

2, ultrasound examination: fetal head diameter, head circumference, abdominal circumference, femur length and gestational age and weight are closely related. The gestational age and fetal size can be estimated from the ultrasound measurements. The measurement of double top diameter is more accurate and less error, such as 85mm, 96% fetal weight 2500g; the reliability of femur length measurement is about 90%, such as 6.8cm, fetal weight 2500g.

Differential diagnosis

False labor is also known as "fake folds." In the third trimester of pregnancy, the uterus undergoes irregular contractions, the so-called Braxtion-Hicks contraction. As the pregnancy progresses, the frequency of this irregular contraction increases and is gradually perceived by the mother. The characteristic of false contraction is that the interval between contractions is irregular; the intensity is not large, only the lower abdomen has slight pain; the duration is not constant, generally no more than 30 seconds, the false contraction is not accompanied by cervical shortening and cervix Expansion, and can be relieved by sedatives. False constriction is a normal physiological phenomenon that contributes to the maturation of the cervix and prepares for childbirth. However, the excessive frequency of the fake contraction can interfere with the rest of the pregnant woman, so that pregnant women are exhausted before delivery. This phenomenon is more common in violent primiparas.
