“How do you drink so much water recently?”

“The day before yesterday, when I went to the labor examination, the doctor said that I had less amniotic fluid. Let me pay more attention these days. I’m in a hurry! “

“Can drinking water increase amniotic fluid???”

Amniotic fluid is a colorless and transparent liquid wrapped around the baby in the uterus. It can protect the fetus from the impact of external forces, can also be produced in the metabolism of the fetus, but also protect the mother, reduce fetal movement caused by discomfort.

Under the condition of normal pregnancy, amniotic fluid will gradually increase with the increase of gestational age, generally about 1000 ml at 38 weeks and 800 ml at full term. Amniotic fluid is the internal environment for babies to survive. Too much or too little amniotic fluid will affect the health of babies. Too little amniotic fluid during pregnancy may be an important manifestation of fetal abnormality or mother’s latent disease, which needs to be paid attention to.

Amniotic fluid index is a dimension to judge the amount of amniotic fluid. The normal range of amniotic fluid index is 5-25cm. If the index of amniotic fluid is less than 8 cm, it can be diagnosed as oligohydramnios.

B-ultrasonic examination of the maximum depth of amniotic fluid pool is also an important standard to determine the amount of amniotic fluid. If it is less than 2cm, it can also be diagnosed as oligohydramnios.

Most hospitals know the condition of amniotic fluid by ultrasound. Generally speaking, the amniotic fluid in full-term pregnancy is too little when the amniotic fluid is less than 300ml.

Oligohydramnios is generally related to fetal malformation, placental dysfunction, overdue pregnancy, intrauterine growth retardation, drug effect and other reasons. Amniotic fluid and placenta are the basis of fetal survival and growth in vivo. The instability of amniotic fluid or placenta will directly affect the growth of fetus.

During pregnancy, if the diagnosis of fetal malformation is clear, the pregnancy should be terminated immediately. Amniotic fluid can be increased by medical and family methods when fetal malformation is clear.

In the case of confirming that the fetus is free of deformity and does not need medical treatment, if it has been found that the amniotic fluid is less, the pregnant mother should pay attention to increasing the blood circulation of the mother through bed rest and drinking more water, and the indirect circulation of uterus and placenta can also be increased, so as to achieve the purpose of increasing amniotic fluid.

When the amniotic fluid is too little, the treatment plan can be selected according to whether the fetus has deformity or gestational age.

If the pregnant mother checks the lack of amniotic fluid in the early or mid pregnancy, it may indicate that the baby has birth defects and cannot produce enough urine to maintain amniotic fluid. If the diagnosis of oligohydramnios combined with fetal malformations should be terminated as soon as possible.

If it is oligohydramnios combined with normal fetus and the fetus is not full-term, the methods of amniotic fluid injection, intravenous infusion, catheter infusion, implantation of shunt can be used to increase amniotic fluid and ensure amniotic fluid volume.

If it is oligohydramnios combined with normal fetus, the fetus is full-term, and the fetus can survive outside the uterus, the pregnancy should be terminated in a timely manner. The method of termination of pregnancy can be induced labor by vagina or cesarean section, which should be selected according to the status of fetus and mother. If the delivery cannot be finished in a short period of time, cesarean section may be performed. If the storage function of the fetus is good, there is no obvious intrauterine hypoxia, and the amniotic fluid is clear after artificial rupture of membrane, the fetus can choose to give birth smoothly.

That is to say, after 37 weeks of pregnancy, the amniotic fluid of the pregnant mother is less, and the amniotic fluid index is between 5-7. If the baby’s development is normal, the fetal position is also normal, which can be observed, but usually pay attention to the number of fetal movements and fetal heart monitoring. If the diagnosis is oligohydramnios and it is in the late stage of pregnancy, after the elimination of fetal malformation and maternal factors, the fetal intrauterine situation can be evaluated in detail, and the pregnancy should be terminated as soon as possible when the fetus is mature.
