What about oligohydramnios in 27 weeks? When oligohydramnios is found, the treatment scheme can be selected according to whether the fetus is deformed or gestational age.
1, oligohydramnios with fetal malformation
If fetal malformation has been diagnosed, the pregnancy should be terminated as soon as possible. Injection of ethacridine through abdominal amniocentesis guided by B-ultrasound can be used to induce labor.
2, oligohydramnios with normal fetus
When oligohydramnios is found, but the fetus develops normally, the cause should be found and removed. Improve placental function and resist infection by increasing fluid replacement. Pregnant women should monitor their fetal movements at ordinary times, and doctors should give biophysical scores to the fetus. The amniotic fluid volume and the ratio of the highest systolic blood flow velocity to the lowest diastolic blood flow velocity (S/D) of umbilical artery were obtained through dynamic monitoring by B-ultrasound, and the fetus was monitored electronically to closely monitor the intrauterine situation.
The specific treatment method is as follows:
(1) Termination of pregnancy
If the pregnancy is full-term and the fetus can survive outside the uterus, the pregnancy should be terminated in time. In case of placental dysfunction, fetal distress, oligohydramnios and serious meconium pollution when the fetal membrane is broken, it is estimated that delivery cannot be terminated in a short time, so cesarean section should be adopted to terminate pregnancy in order to reduce the perinatal mortality rate.
If the fetal reserve function is still good, there is no obvious intrauterine hypoxia, and the amniotic fluid is clear after artificial rupture, vaginal trial delivery can be carried out. If you choose vaginal trial delivery, you need to closely observe the progress of labor and continuously monitor the changes of fetal heart rate.
(2) Increase amniotic fluid volume and look forward to treatment.
For those with premature pregnancy and immature fetal lungs, it is feasible to increase amniotic fluid volume and expect treatment to prolong pregnancy. Amniotic cavity perfusion can be used to reduce the incidence of fetal heart rate variability deceleration, amniotic fluid fecal contamination rate and cesarean section rate. At the same time, uterine contraction inhibitors should also be used to prevent premature delivery.
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.
Amniotic fluid index standard 1. Amniotic fluid depth
Amniotic fluid depth is an important index to judge the amount of amniotic fluid, and it is the vertical depth of sheep pond displayed by B-ultrasound. Normal amniotic fluid depth is 3-8cm. When it is less than 3cm, meconium is easy to deposit, which may cause premature delivery or asphyxia of the fetus.
2. Amniotic fluid index
The uterus is divided into four quadrants: upper left quadrant, upper right quadrant, lower left quadrant and lower right quadrant. Amniotic fluid index AFL refers to the sum of the vertical depths of the largest dark area of amniotic fluid in these four quadrants. The normal range of amniotic fluid water stopping is 18-24cm.
3. Amniotic fluid measurement
Hospitals usually know whether the amniotic fluid volume is normal by ultrasound. Amniotic fluid measurement is an important index to evaluate whether pregnant women are normal or not. Amniotic fluid measurement is to sum the maximum depth of amniotic fluid in each of the four quadrants, and the normal range is 8-27cm.
