Low amniotic fluid in late pregnancy is often caused by placental hypoplasia, amniotic membrane lesions, hypertensive disorders of pregnancy, etc. It is necessary to actively search for the cause and treat the symptoms. And timely termination of pregnancy at the right time. For different causes, there are different treatment measures, rapid water intake, intravenous fluid rehydration, and even the administration of low molecular heparin and other treatments. 1. While actively searching for and promptly removing the etiology of the disease, it is important to increase dynamic monitoring of the intrauterine condition of the fetus. If the amniotic fluid is too low, there is no malformation in the fetal examination, and the pregnant woman has no serious complications, the amount of amniotic fluid can be increased by drinking water quickly, and if the amount of amniotic fluid can be restored to the normal range, there is no problem. If the amniotic fluid volume is still relatively low, attention should be paid to finding the cause. 2. If the amniotic fluid is low due to insufficient maternal blood volume or lack of oxygen, drinking a lot of water, intravenous fluids and oxygen can indeed play a certain role. For pregnant women with hypercoagulability, subcutaneous injection of low molecular heparin or intravenous infusion of low molecular dextrose will also be given under doctor’s guidance to make the blood circulation of the placenta smoother, which is conducive to the formation of amniotic fluid. In addition, a pH test paper is used to rule out the presence of water breakage, and it will be necessary to decide what to do depending on the week of pregnancy. There is no premature rupture of membranes, which is often caused by aging placental function. When low amniotic fluid occurs in late pregnancy, it is important to seek medical examination to clarify the cause of the condition and follow the doctor’s instructions.
