The fetus is prone to hypoxia during the third trimester, and the fetus will send 5 major hypoxia signals. Pregnant mothers must respond in a timely manner

Guide: related knowledge of hypoxia in the palace

We all know that the fetus is most afraid of hypoxia in the third trimester. After 36 weeks, we must do fetal heart monitoring every week, and pay close attention to fetal movements, and we are afraid of the fetus hypoxia.Many pregnant mothers do not know the harm of hypoxia and think that there is no need to be so nervous.Some pregnant mothers have an attitude towards the birth of the third trimester. They are waiting for the creamy to be cooked, and they have not seen it. They found that they had died in the hospital.

The fetus is prone to symptoms of hypoxia in the third trimester. What are the harms, what are the causes, how to find it?Let’s talk about this topic together.

A fetal hypoxia refers to a phenomenon of decreased oxygen and nutritional supply of fetus in the palace, which leads to distress in the fetus.According to the "Eighth Edition of Obstetrics and Gynecology" and "The Holy Ceremony of Pregnancy": During the hypoxia in the palace, the growth and development of the fetus will be restricted, the growth delays, less than the corresponding date, and less than the pregnancy age.When the fetus is hypoxic, it is easy to inhale amniotic fluid, and the problem of inhaling pneumonia occurs after birth.When the fetus is hypoxic, it is easy to discharge tire feces, contaminate amniotic fluid, and cause fetal manure inhalation syndrome.When the fetus is hypoxic, if it is not intervened in time, brain and heart damage, or even death may occur.It can be seen how much fetal hypoxia is.

There are acute hypoxia and chronic hypoxia for fetal hypoxia. There are reasons for pregnant mothers and fetuses. There are also factors for fetal cords and placenta. It is a comprehensive complex problem.

1. The factors of pregnant mothers

When pregnant mothers have severe blood circulation such as shock, at the time of use, acute fetal hypoxia will occur when the anesthesia is excessive.Pregnant mothers have insufficient blood oxygen content, such as congenital heart disease, lung infection, lung dysfunction, asthma and severe anemia; when uterine placental blood vessels are sclerosis, such as pregnancy hypertension, chronic nephritis, diabetes, and delivery, this isChronic fetal hypoxia will occur in two types.

2. Fetal factors

The fetus suffers from severe cardiovascular disease, respiratory disease, fetal malformations, maternal and child blood types, intrauterine infections, and brain damage. The ability of the fetus to transport oxygen and oxygen will decrease, which will cause hypoxia.

3. Umbilical cord, placenta factors

The umbilical cord and placenta are the transmission and transmission channels of inter -fetal oxygen and nutrients. If dysfunction occurs, it will affect the fetus cannot obtain sufficient oxygen and nutrition.Such as umbilical cord knot, umbilical cord twist, umbilical cord around the neck, umbilical cord prolapse, umbilical cord hematoma, too long or shorter umbilical cord, umbilical cord attached to the placental membrane; premature placenta, placental peeling, aging placenta, abnormal shape of the placenta, excessive placenta, excessive placentaLarge or too small, incomplete function of placenta.

1. fetal movement

When the fetus is hypoxic, the fetal movement will be frequently reduced or disappeared. Usually pay attention to counting the fetal movement."The Eighth Edition of Obstetrics and Gynecology" reminds: If the fetal movement count is greater than equal to 6 times/2 hours, it is normal. If it is less than 6 times/2 hours or 50%, it is prompted to be hypoxic."Zheng Yu Qiao Parenting Scripture-Fetal Volume" mentioned that after 28 weeks of pregnancy, it is necessary to regulate the daily fetal movement every day.EssenceThe number of tires 3 times is 4, that is, a 12 -hour fetal movement, and then 6 is the number of fetal movements in 2 hours, which can be compared with the above standards.

2. fetal heart rate

The normal fetal heart rate base line standard is 110-160 times/min, and the fetal heart rate is less than 110/min, which is a hypoxia state.When the fetal heart rate is less than 100 times/min and the fluctuation is less than 5 times/min, it is severe hypoxia, which is likely to be in the palace.Because there is also a periodic for check -up, it will be checked once a week after 36 weeks, but there are still many uncertainty.If there are some factors that may cause fetal hypoxia, you can bring a fetal heart rate detector for daily fetal heart rate testing, and some can also record the number of fetal movements at the same time.

3. Felty heart monitoring

In the third trimester of pregnancy, there is a problem of hypoxia in the treatment of fetal heart monitoring. The fetal heart monitoring is a monitoring method of whether the fetal heart rate changes during fetal movement and contraction.When the fetal heart rate exceeds 110-160 times/min, or when the number of fetal movements is less than 3 times in 20 minutes, it can be judged as a hypoxia, the need to retake the oxygen, and observe whether it improves.This situation is very common in clinical practice, and I encountered many times when I went to fetal heart monitoring.When I gave birth to Dabao, I was also tested by the fetal heart to be detected by hypoxia.

4. The feeling of pregnant mothers

If the pregnant mother has a white face, white lips, accelerated heartbeat, severe itching of the whole body, and difficulty breathing, it may be prompted that the oxygen supply is insufficient.

5. Study in fetal growth and development

To do B -ultrasound, you can check the fetal’s double -top diameter, femoral long, and abdominal circumference indicators. If these indicators are less than 2 weeks of standard value, it is prompted that the fetus may have a hypoxia, and it must be eliminated in time.

1. Pay attention to the left lying rest

Usually pay attention to rest on the left side. The posture on the left lying on the left can reduce the degree of right rotation of the uterus, reduce the tension of the uterine vascular tension and the pressure on the aorta and skeletal artery, increase the blood flow of the placenta, and improve the oxygen supply state in the uterus, which is conducive to the state of oxygen supply, which is conducive to conducive toFetal growth and development.

2. Oxygen absorption

Oxygen absorption 2-3 times a day, 30 minutes per oxygen per time, provides enough fetal oxygen by forced oxygen inhalation.Many clinics or hospitals provide such services.It is not recommended to purchase oxygen -absorbing equipment by yourself. If you control it, it is easy to cause mistakes. It is more appropriate to go to a professional medical institution.

3. Timely eliminate the disease factors

For some diseases that cause hypoxia, it is necessary to control it in time, such as pregnancy hypertension and gestational diabetes, to increase the frequency of production examination, and use the appropriate treatment method for treatment to avoid serious hypoxia caused by the fetus.

4. Inspection on time

Do a good job of delivery on time and find out whether the fetal development is normal in time.Do fetal heart monitoring regularly, discover the fetal abnormalities in time, and deal with it in time.By 36 weeks, a fetal heart monitoring is performed once a week. If the risk of hypoxia is greater, it is recommended to do 2-3 fetal heart monitoring 2-3 times a week in order to control or terminate pregnancy in time to save the fetus of the fetus.

In short, the fetal hypoxia is seriously harmful to the health of the fetus and the results of adverse results. It is also a heavy blow for pregnant mothers. Do not ignore the problem of hypoxia during pregnancy, check on time, pay attention to fetal movement, and extinguish the fire of the stars in time.
