Although the pregnant woman Xing'er is 29 weeks pregnant, her personality is a big grin, and she is more careless in doing things, and she is an optimist.
At the last obstetric examination, the doctor mentioned that the fetal umbilical cord is around the neck 3 times, and when going home, it is necessary to pay attention to the number of fetal movements.
When she got home, her life was still the same as before, eating well and sleeping soundly.
Sometimes when she thinks about it, she counts the fetal movements, and when she is particularly busy, she will leave it behind.
One day, when the husband was off work, the two talked about the fetus, Xing'er realized that there was no fetal movement today, and the fetus did not move much this afternoon, the two thought that this was troublesome, panicked and went to the hospital for examination, the result was that the fetal supervision failed, and the fetal movement of the fetus was very weak.
The doctor quickly arranged an emergency caesarean section for Xing'er, and when the fetus was taken out, the whole body turned purple, but fortunately, the baby finally turned the corner.
The doctor breathed a sigh of relief, fortunately you came in time, otherwise you would really regret it.
What is intrauterine hypoxia in the fetus?
Fetal hypoxia is common in the third trimester or when pregnant women are about to give birth, the fetal heart rate decreases, and the fetal movement decreases. Pregnant women's own diseases, such as pregnancy hypertension, can lead to intrauterine hypoxia in the fetus.
Umbilical cord blood transport is not smooth, the placenta is too large and too small, the placenta is abnormal and infected, so that the fetus can not smoothly obtain sufficient oxygen and nutrients, which can easily lead to intrauterine hypoxia of the fetus.
Malformed children or fetal cardiovascular insufficiency can also easily lead to fetal hypoxia.
The consequences of fetal hypoxia are very serious, which will not only lead to fetal growth retardation, but also lead to fetal accidents.
The closer to the expected date of delivery, the symptoms of fetal hypoxia will slowly worsen, and the longer the hypoxia, the more serious the developmental delay of the fetus.
Cord wrapped around the neck, prolapse or knots, placental abruption, and strong contractions are the main causes of acute fetal hypoxia.
Acute fetal hypoxia is common in the third trimester, and is manifested by changes in fetal heart rate, frequent or absent fetal movements, amniotic fluid meconium contamination, and so on.
What are the manifestations of intrauterine hypoxia in the fetus?
1. No fetal movement for a long time
If the pregnant woman feels that there is not a single fetal movement for several hours in a row, even if the pregnant woman taps the stomach, the fetus does not respond to fetal movement, and the fetus may have been deprived of oxygen.
2. Fetal heart rate abnormality
The fetal heart rate of the fetus suddenly accelerates, from strong to weak, becomes irregular, exceeding the normal range of the fetal heart rate.
If the fetus is deprived of oxygen for a long time and the fetal movement stops, the fetal heartbeat will slowly disappear within 24 hours.
3. Fetal movement is intensified
Pregnant women can feel the fetal struggle, at this time may be the umbilical cord suddenly wrapped too tight, resulting in fetal hypoxia.
4. Fetal heart rate monitoring is not up to standard
If the fetus is hypoxic, fetal heartbeat monitoring will show abnormal fetal movement and the fetal monitoring will be unqualified.
What should I do if the fetus is deprived of oxygen during pregnancy?
After the pregnant woman inhales oxygen, the maternal blood oxygen content increases, the fetal hypoxia is improved, and the pregnant woman needs regular obstetric examinations to detect the development of the fetus.
If the pregnant woman's uterine opening is complete and the fetus is deprived of oxygen, then a vaginal delivery can be tried.
If the uterine opening of the pregnant woman has not been fully opened, the pregnant woman changes to the left lying position, after 10 minutes, the fetal heart rate slowly returns to normal, you can continue to observe the situation of the fetus, once the fetus has a lack of oxygen, it is necessary to respond in time.
Before delivery, if the oxytocin contraction is too strong, it may lead to a decrease in the fetal heartbeat, and if the oxytocin is stopped, the fetus is still hypoxic, and the pregnant woman can only have an emergency caesarean section.
Under the action of oxytocin, the contractions of the pregnant woman Xiaomei are too strong, and the fetal umbilical cord is wrapped around the neck and is prone to lack of oxygen.
Fortunately, oxytocin was later stopped, the contractions became slower, the baby's hypoxia was alleviated, and finally after a smooth delivery, the baby was born smoothly.
How can pregnant women prevent intrauterine hypoxia in the fetus during pregnancy?
Pregnant women should do fetal heart rate monitoring on time during pregnancy
The normal fetal heart rate is 120-160 beats / min, fetal movement is less than 100 / time per minute, or more than 160 times, are abnormal fetal movements, then the doctor will judge the fetus to have intrauterine distress.
2. Uterine height and growth of abdominal circumference in pregnant women
If the fetus is chronically hypoxia in the womb, the development of the fetus will be delayed, and the uterine height and abdominal circumference of the pregnant woman will not change for two weeks, or the growth will be slower.
3. If the fetus has an umbilical cord around the neck, pregnant women usually do not touch the stomach frequently
Pregnant women should not touch the stomach too much, so as not to disturb the fetus, causing the fetal umbilical cord to be more serious around the neck.
4. Pregnant women usually pay attention to the number of fetal movements at home, especially if there is too little amniotic fluid, and the number of umbilical cords around the neck should be increased
Several fetal movements occur for 3 hours a day, normal fetal movements occur 3 times within 1 hour, and continuous fetal movements are only counted as one fetal movement.
If there are less than 3 times in an hour and less than 10 fetal movements for 12 hours, the fetus may already have intrauterine distress.
5. Listen to fetal heart sounds
If fetal motility is reduced, or if fetal movement is overfrequent, fetal hypoxia is likely to occur.
6. Pregnant women should avoid doing too heavy housework or often go to places with dense crowds to reduce the collision of external forces on the abdomen of pregnant women
7. When pregnant women sleep, try to choose the left lying position, which can improve the blood supply to the placenta and allow the fetus to absorb more oxygen
epilogue
Although the consequences of fetal hypoxia are very terrible, but the fetus is hypoxic, there will be four major manifestations, pregnant women to prevent fetal hypoxia, need to pay attention to these 7 points, then the fetus can successfully pass the pregnancy and be born safely.
