Low amniotic fluid in 36 weeks of pregnancy can be remedied by drinking water, intravenous infusion, amniotic fluid infusion and other methods. 1. Drinking water: when replenishing amniotic fluid through drinking water, attention should be paid to replenish a large amount of water in a short period of time. Generally speaking, you can drink 2,000 ml of water within 2 hours or drink water several times a day, and the total amount of water can be up to 4,000 ml, which can replenish the fetus’s need for water more quickly. 2. Intravenous fluids: If you can’t drink a lot of water, then you can increase the blood volume of the mother’s body through intravenous fluids to increase the amniotic fluid. 3. Amniotic fluid infusion: If it is not possible to replenish amniotic fluid after trying the above methods, then we can consider injecting 100~700ml of saline into the amniotic cavity with a puncture needle to replenish amniotic fluid. It is recommended to pay more attention to regular checkups during pregnancy, and if the fetus has symptoms of ischemia and hypoxia, timely intervention should be carried out, and in serious cases, early cesarean section is needed.
