4hw.com.cn: although too much amniotic fluid is a common phenomenon, its harm can not be ignored, and there is a way to treat it. So what should we do about too much amniotic fluid? How to control too much amniotic fluid? Xiaobian has collected a lot of information about the treatment of too much amniotic fluid. Let's follow Xiaobian to learn more about it~
Medical treatment of amniotic fluid excess
Therapeutic principles
1. In case of excessive amniotic fluid and fetal malformation, the pregnancy should be terminated in time.
2. If the amniotic fluid is too much, no deformity is found by B ultrasound, and AFP is normal, the pregnancy can continue.
Specific treatment
The termination method for the patients with excessive amniotic fluid and fetal malformation depends on the amount of amniotic fluid and cervical maturity.
(1) Puncture and induction of labor: chronic amniotic fluid is too much, which is generally good. Appropriate amount of amniotic fluid is discharged through amniocentesis, and ethacridine 50-100mg is injected to induce labor.
(2) Induced labor by high-level amniotic fluid: high-level amniotic fluid was used at a speed of 500ml / h. During amniotic fluid drainage, attention should be paid to the sudden decrease of uterine pressure to cause placental abruption. Pay attention to blood pressure and pulse. Sandbags or abdominal straps can be placed on the abdomen to prevent shock. Antibiotics can be used 12 hours after membrane rupture. If 24 hours is still especially uterine contraction, use oxytocin induced labor.
(3) Artificial rupture of membrane after abdominal puncture: first puncture through the abdomen, release part of amniotic fluid, reduce the number of artificial rupture of membrane, can avoid placental abruption.
Excess amniotic fluid with normal fetus
(1) Generally, patients with chronic amniotic fluid excess who have no obvious symptoms can be given rest, low salt diet, sedative as appropriate, and regular observation of amniotic fluid volume.
(2) Indomethacin is an inhibitor of prostaglandin synthetase, which can reduce fetal urine excretion and promote the reabsorption of amniotic fluid through the lung. The dosage is 25mg, three times a day. The side effect of indomethacin is that the fetal artery catheter is closed in advance, which usually occurs after 32 weeks of pregnancy. Therefore, the duration of indomethacin is 22-31 weeks, and it should be continued for 3 weeks. The changes of amniotic fluid volume and the occurrence of fetal artery stenosis were monitored.
(3) Amniocentesis and drainage of amniotic fluid can be performed under the guidance of B-ultrasound if the gestational age of amniocentesis and drainage of amniotic fluid is less than 37 weeks and the symptoms of excessive amniotic fluid are serious. The amniotic fluid should be discharged at the rate of 500 ml per hour without puncture of placenta and fetus, and the volume of amniotic fluid should not exceed 1500 ml at one time. It is easy to cause premature delivery or placental abruption due to too fast and too much liquid discharge, which should be based on the remission of pregnant women's symptoms. Attention should be paid to aseptic operation, antibiotics should be given to prevent infection after operation, and uterine contraction inhibitors and sedatives should be used to prevent premature delivery.
