What effect does amniotic fluid have on the fetus? Many people know amniotic fluid, so do you know what amniotic fluid is? Amniotic fluid refers to the fluid in the amniotic cavity of uterus during pregnancy. Amniotic fluid is the most indispensable for maintaining the fetus. So there is less amniotic fluid, and different problems will follow. Below, I would like to share with you the impact of amniotic fluid deficiency on the fetus.
What effect does oligohydramnios have on the fetus? 1 What effect does oligohydramnios have on the fetus?
1, oligohydramnios will lead to a significant increase in perinatal mortality.
In mild oligohydramnios, the perinatal mortality rate increased by 65438 03 times. In severe oligohydramnios, the perinatal mortality rate increased by 47 times, and the main causes of death were fetal hypoxia and fetal malformation.
2, oligohydramnios can lead to fetal development malformation.
If oligohydramnios occurs in the early stage, the adhesion between fetal membrane and carcass will cause fetal malformation and even limb loss; If it occurs in the second and third trimester of pregnancy, the fetal skin is dry, such as parchment; Extrauterine pressure directly acts on the fetus, causing fetal musculoskeletal deformities, such as torticollis, hunchback, hand and foot deformities, etc. Oligohydramnios caused by congenital nephropathy can cause Porter's syndrome (pulmonary hypoplasia, flat nose, low ear position, shovel hand, arched leg, etc. ), and the prognosis is very poor. Most children die after giving birth.
3. Fetal lung dysplasia.
Possible reasons are: lung development defect, unable to excrete fluid to maintain amniotic fluid volume; Due to the lack of amniotic fluid, the uterus compresses the fetal chest, affecting the expansion of the chest wall and lungs; Lack of fluid inhalation in alveoli will hinder lung development. During normal pregnancy, it is very important to inhale appropriate amniotic fluid for the expansion and development of fetal lungs.
Expectant mothers should pay attention to the fact that lack of amniotic fluid does not directly affect delivery. Only in the case of amniotic fluid deficiency and fetal growth retardation at the same time, it is necessary to have an early caesarean section. Expectant mothers with less amniotic fluid should first listen to the doctor's advice to see if they need to give birth early. If not, they only need to do a good job in fetal heart monitoring period and some basic treatment methods to reach the expected date of delivery of umbilical cord.
What should I do if the amniotic fluid is less?
1. If oligohydramnios are found during pregnancy, the pregnancy should be terminated immediately in case of definite fetal malformation.
2. If the diagnosis of oligohydramnios during pregnancy is clear that there is no fetal malformation and the fetus is mature, termination of pregnancy can be considered, and cesarean section can be considered as a way to terminate pregnancy.
3. Oligohydramnios caused by insufficient blood volume or lack of oxygen can really play a role by drinking plenty of water, intravenous infusion and oxygen inhalation.
4. For pregnant mothers in hypercoagulable state, low molecular weight heparin can be injected subcutaneously, or low molecular weight dextran can be injected intravenously, so that the blood is not so easy to coagulate, and the blood circulation of the placenta is smoother, which is beneficial to the formation of amniotic fluid.
5. Amniotic cavity perfusion method: the decrease of amniotic fluid volume is the main reason for the adverse effects of oligohydramnios on mother and fetus during pregnancy and delivery. Increasing amniotic fluid volume by amniotic cavity perfusion is a targeted therapeutic measure. Intraamniotic perfusion therapy, that is, injecting a proper amount of normal saline into amniotic cavity with puncture needle under the guidance of B-ultrasound, can improve the condition of oligohydramnios. This method is now recognized and adopted by more and more people, especially for some pregnant women with early unexplained oligohydramnios and immature fetus. Amniotic fluid perfusion can improve the effect of oligohydramnios on the fetus in a short time and maintain the normal development of the fetus.
Daily nursing
Expectant mothers with oligohydramnios are advised to stay in bed on the left side to improve the blood supply to the placenta. At the same time, expectant mothers with oligohydramnios are under great psychological pressure, so doctors have the responsibility to explain their illness to pregnant women and their families, provide emotional support, and help them actively participate in treatment and self-care nursing. It is necessary to inform expectant mothers of the benefits of maintaining a happy mood and cooperating with treatment on fetal development. Family members should also give more psychological comfort and care to help eliminate the psychological worries of expectant mothers.
The above is an introduction about the influence of oligohydramnios on the fetus. Oligohydramnios affects fetal health. What should pregnant women do? Expectant mothers should pay attention.
What effect does oligohydramnios have on the fetus? 2 1. amniotic membrane rupture leads to oligohydramnios.
Even a small crack in the amniotic membrane will let some sheep flow out. This can happen at any stage of your pregnancy. However, it will be more common near production. If you notice that your underwear is wet, you will find that your amniotic fluid is leaking; Or when the doctor examines you, you may find that.
Amniotic membrane rupture will increase the risk of infection for you and your baby, because it will provide a channel for bacteria to enter the amniotic cavity. Sometimes small cracks will heal themselves, amniotic fluid will no longer leak, and the amount of amniotic fluid will return to normal. If amniocentesis causes amniotic fluid leakage, it usually happens.
2, placental problems lead to less amniotic fluid.
If there is something wrong with the placenta, such as partial abruption, the placenta can't supply enough blood and nutrition to the baby, which leads to the interruption of amniotic fluid circulation.
3. Some disease factors lead to oligohydramnios.
Some diseases can also lead to oligohydramnios, such as chronic hypertension, preeclampsia, diabetes and lupus.
4, twins or multiple births cause oligohydramnios.
If you are pregnant with twins or multiple births, you may also have oligohydramnios. In the case of twin transfusion syndrome, there may also be oligohydramnios, one baby with oligohydramnios and the other with polyhydramnios.
5, fetal malformation leads to oligohydramnios.
If oligohydramnios is detected in the first or second trimester, it may indicate that the baby will have birth defects. If the baby does not have a kidney, renal dysplasia (Porter's syndrome) or urethral obstruction, it cannot produce enough urine to maintain the amniotic fluid volume. Congenital heart defects can also cause this problem.
What should I do if the amniotic fluid is less?
The amount of amniotic fluid in the third trimester is less than 300ml, which is called oligohydramnios. When oligohydramnios occur, the amniotic fluid is thick, turbid and dark green. Oligohydramnios in the first and second trimester of pregnancy often end in abortion. In the past, it was thought that the incidence of oligohydramnios was about 0.65438 0%, but in recent years, due to the wide application of B-ultrasound, the detection rate of oligohydramnios was 5% ~ 4%, and the incidence rate increased.
During pregnancy, the quantity and composition of amniotic fluid are not fixed, but in a relatively stable dynamic process of continuous production and absorption. Oligohydramnios will occur when the amniotic fluid production decreases or the amniotic fluid absorption increases, and the amniotic fluid production is less than the amniotic fluid absorption.
Fetal urine, fetal swallowing, fetal respiratory movement, fetal skin and fetal membranes (including amniotic membrane and chorion) are mainly involved in the production and absorption of amniotic fluid. Fetal urine is the main source of amniotic fluid, and fetal swallowing is the main factor of amniotic fluid absorption. Other factors may have dual effects on amniotic fluid production and absorption.
Too little has different effects on pregnant mothers and fetuses, so attention should be paid to it. Once the pregnant mother finds that the abdominal growth is not obvious or the fetal movement is abnormal, she should go to the hospital for examination in time and make necessary treatment under the guidance of a doctor. First of all, let's understand the impact on the baby.
1, oligohydramnios occurs in the early pregnancy, and the fetal membrane can adhere to the fetus, resulting in severe fetal malformation.
2. In the second and third trimester of pregnancy, the buffering effect of amniotic fluid disappears, and the uterine pressure can directly act on the fetus, causing torticollis with curved back, giant jaw, hand and foot deformity. Fetal chest wall can be compressed, lung expansion leads to pulmonary hypoplasia, and the incidence of respiratory distress syndrome increases significantly after birth.
3. Oligohydramnios during delivery can lead to fetal umbilical cord compression, fetal distress or neonatal asphyxia during uterine contraction. If complicated with amniotic fluid turbidity at the same time, it can cause neonatal aspiration pneumonia or respiratory tract obstruction, and increase neonatal mortality.
4. The influence of amniotic fluid on pregnant mothers mainly includes: oligohydramnios in the third trimester may be caused by low blood volume of pregnant mothers, using indomethacin to protect the fetus and using captopril to treat hypertensive disorder complicating pregnancy. In the process of delivery, oligohydramnios usually have uncoordinated contractions, slow cervical dilatation, umbilical cord compression, fetal distress and so on, so the rate of cesarean section increases.
