As we all know, the baby in the pregnant mother lives in an environment full of amniotic fluid.As a substance that is closely in contact with the baby at all times, I believe that pregnant mothers feel that they are familiar and unfamiliar with amniotic fluid.
It often appears in the topic of pregnant mothers, and it is indispensable for each birth check; how does it come from, why is it called "sheep", what components contain, what will happen?Moms and dads are curious.
Why is amniotic fluid called "amniotic fluid, not" human water "," pig water "," beef water "or" monkey water "?
There are many opinions about the origin of this name:
First, when people saw a layer of film wrapped around the baby in ancient times, they felt similar to sheep intestine, which was called amniotic fluid.
The second is that amniotic fluid comes from the theory of yin and yang of traditional Chinese medicine."Sheep" and "Yang" are connected, and the same sound.The beginning of human life cannot be separated from the sun, so the source of human life is "amniotic fluid", which means Yangshou and life.
The third is that amniotic fluid exists in the amniotic membrane. The saying of amniotic fluid comes from Greek AMNOS, which means lamb.Because the lamb was born a layer of fetal membrane at birth, this usage extended this usage and translated into amniotic membrane.
Fourth in Han culture, sheep represent nourishment, beauty, and auspiciousness. The typical Chinese characters "raising, beautiful, auspicious, meals, and fresh" all have sheep, and amniotic fluid means nourishing the baby’s water.
Anyway, no matter what kind of statement, it is no longer able to sophisticated, and this name is also fixed.
The early amniotic fluid was formed by the tissue liquid exuded from the fertilized egg nucleus. In the middle of the pregnancy, the tissue liquid from the amniotic, placenta, and umbilical cord exuded. By 5 months of pregnancy, the fetus began to urinate and became one of the amniotic fluid.
As the infant embryo organs slowly mature, the baby continues to obtain water from the placenta, and the swallowed amniotic fluid forms urine to discharge the urine through the kidneys to continuously circulate.Therefore, we all grew up drinking our own urine.
However, the fetal urine composition is different from the birth after birth. Although the amniotic fluid contains fetal urine, it is actually not what you think.98%are water, and there are a small amount of inorganic salt, urea, uric acid, creatinine, fetal fat and fetal epithelial cells.If you are diagnosed with diseases such as fetal chromosomal abnormalities, you can obtain the fetal cells by pumping and sucking amniotic fluid.
When the abdomen of the pregnant mother is affected by foreign pressure and impact, amniotic fluid can play a certain buffering role to avoid and slow the baby’s injury.When pregnant mothers walk or do other movements, the baby floats in amniotic fluid, so as not to shake too much.
Amniotic fluid can also keep the uterus a relatively constant temperature and provide a warm and suitable growth environment for the baby.More importantly, with the "stretching" uterus of amniotic fluid, the baby has sufficient activity space. You can stretch your arms and kick your calves to avoid space limitations and restrict development.
During childbirth, the amniotic fluid will form an front amniotic fluid in front of the fetus’s head to expand the cervix, reduce the pressure caused by contractions on the fetus, and have a certain lubrication effect, which is easy to give birth to the baby’s delivery.
For amniotic fluid, the most nervous of pregnant mothers must be that during the checkup, the doctor said too much or too little.
During the full moon pregnancy, the amount of amniotic fluid is generally 800 to 1000ml.At any time of pregnancy, more than 2000ml of amniotic fluid is called too much amniotic fluid; after 28 weeks of pregnancy, the amniotic fluid less than 300ml is called too little amniotic fluid.It can be seen that the amplitude between too much and too little is still very large. Within this range, more and less will not have any effects, don’t be too tangled.
However, if it really exceeds 2000ml, it is necessary to carefully check whether there are congenital abnormalities (such as tracheal esophageal fistula, duodenal lock), multi -fetal pregnancy, placental umbilical cord vascular lesions, pregnancy with diabetes, and maternal blood types.
Even if there is no cause, too much amniotic fluid will cause the uterine capacity to increase, induce premature shrinkage of the uterus and cause premature birth. At the same time, the incidence of abnormal fetal abnormalities will increase significantly, increasing the risk of premature fetal rupture.Liestone puncture can be performed to reduce the amount of amniotic fluid.
When there is too little amniotic fluid, we must pay attention to abnormal urinary system deformed and restricted in the fetal palace.If the diagnosis of the fetus has malformations, you can consider whether to terminate your pregnancy in combination with the opinions of the doctor and your own situation; for the fetus that does not have a clear diagnosis but not the pregnancy, it can increase the amount of tonic and accept strict medical monitoring; for no clear diagnosis diagnosis, there is no clear diagnosis diagnosisFits that are abnormal and pregnant are full of pregnancy, and pregnancy can be considered in advance.
So, how can pregnant mothers know whether their amniotic fluid quality is good?There are about 4 feelings:
1. The fetal movement is normal.It is generally recommended to start several fetal movements at 30-32 weeks. The fetal movement per hour is 3-5 times, and the 12-hour fetal movement is more than 30-40 times.If the number of fetal movements is abnormal, the risk of abnormal amniotic fluid will be higher.
2. The growth of the abdomen is normal.As the pregnancy week continues to increase, the baby is also growing, and the stomach of the pregnant mother has gradually grown up.After 20 to 24 weeks, the growth rate is about 1.6 cm per week. At about 37 weeks, the growth rate of the abdomen is slow or stopped.Pregnant mothers can roughly determine whether the baby or amniotic fluid is normal through the abdomen circumference.
3. Normal urination.The amount of amniotic fluid is related to the amount of water intake.If the pregnant mother has sufficient amniotic fluid, there should be no obvious abnormalities in urine and urine.And if the urine color of the expectant mother is dark and the number of urination times is small, there may be a situation where there is less amniotic fluid, and you should go to the hospital in time.
4. Full of spirit.If the pregnant mother is in good mental state, the quality of sleep is high, and there are generally no problems with amniotic fluid.But if the mental state is poor and pale, it may affect amniotic fluid.
