How to replenish the amniotic fluid quickly at 38 weeks

When it comes to amniotic fluid, everyone is very familiar with it, especially expectant mothers. Amniotic fluid has special significance for both pregnant mothers and babies. Too much or too little amniotic fluid can cause great harm to us. So, how can we replenish the amniotic fluid faster at 38 weeks? What are the reasons for low amniotic fluid? Let’s take a look.

How to replenish amniotic fluid faster at 38 weeks

In recent years, the use of amniotic fluid intravenous drip to prevent oligohydramnios in the middle and late stages of pregnancy has achieved remarkable results. One of the methods is to place a pressure measuring tube and a hair electrode in the amniotic cavity to monitor the fetus during delivery, and to infuse 37°C 0.85% saline into the amniotic cavity at a rate of 15-250 l per minute until the fetal heart rate decreases or the AFI reaches 8 cm. Generally, it takes about 250L (100-700mL) of saline solution to eliminate the genetic variation in the fetal heart rate. If the gene mutation rate does not subside after infusion of 800ml, it is considered unsuccessful. Intra-amniotic intravenous drip can eliminate the stress on the fetal umbilical cord, reduce the rate of fetal heart rate mutation, reduce the rate of meconium excretion and cesarean section, and improve the survival rate of newborns. It is a safe, economical and effective method. However, repeated intra-amniotic intravenous drip has complications such as chorioamnionitis.

Too little amniotic fluid is a serious risk to the fetus and a very important signal. If the pregnancy is full-term, rupture of membranes should be performed as soon as possible to induce abortion. After rupture of membranes, if the amniotic fluid is small and thick, there is severe meconium contamination, and fetal distress occurs, it is estimated that the delivery cannot be completed in the short term. After excluding abnormal fetuses, cesarean section should be chosen to complete the delivery. Cesarean section can dramatically reduce perinatal mortality compared to natural delivery.

What are the reasons for low amniotic fluid in pregnant women?

First, the deformed fetus. For example, if the fetus has congenital renal defects, renal dysplasia, urethral tube or urethral stenosis and other malformations, resulting in oliguria or anuria, it will cause oligohydramnios.

Second, overdue pregnancy. In case of overdue pregnancy, the placenta function is reduced, the amount of fluid injection is insufficient, the fetus is dehydrated, and there is less amniotic fluid. Some experts and scholars also believe that in overdue pregnancy, the fetus is too mature, its renal tubules are more sensitive to adrenal hormones, and the urine output is low, resulting in too little amniotic fluid. The incidence of oligohydramnios caused by post-term pregnancy is as high as 20% to 30%.

Third, the baby’s intrauterine language growth retardation (IUGR). Oligohydramnios is one of the characteristics of intrauterine language development retardation in the fetus. Chronic hypoxia causes redistribution of the fetal blood circulation, mainly supplying the brain and heart, while renal blood volume decreases and fetal urine conversion decreases, resulting in oligohydramnios.

In general, if there is too little amniotic fluid at 38 weeks of pregnancy, relevant treatment methods should be used to treat it. Too much amniotic fluid will make pregnancy difficult. Prenatal examinations can reflect the amniotic fluid status of pregnant women to a certain extent. Therefore, prenatal check-ups are particularly important. Pregnant mothers should have regular, timely, and thorough prenatal check-ups.
