At 32 weeks of pregnancy, the normal value of amniotic fluid depth is 3-8cm. amniotic fluid depth refers to the depth of the deepest amniotic level, generally speaking, amniotic fluid depth <3cm is considered too little amniotic fluid, if amniotic fluid depth >8cm, excessive amniotic fluid is considered. At 32 weeks of pregnancy, if there is any abnormality in the amniotic fluid volume, it is recommended to review the ultrasound after 2 weeks and also pay attention to the amniotic fluid volume. Low amniotic fluid may be due to abnormal fetal kidney development and possibly decreased placental function. When the amniotic fluid is too low, acute intrauterine distress or even fetal death may occur and fetal heart monitoring is needed to note whether the fetal heart is responding well. If the fetus is hypoxic, it is recommended to lie on the left side, administer oxygen and review the fetal heart monitoring. When the amniotic fluid is too low, the pregnant woman can drink more water and increase the amount of water to promote the increase of amniotic fluid, as well as regular pregnancy checkups and review the amniotic fluid volume. When the amniotic fluid is too much, pay attention to whether the fetus has neurological or digestive abnormalities, commonly fetal tracheal and esophageal fistula. It is also important to pay attention to whether the pregnant woman has gestational diabetes, and a glucose tolerance test is recommended. Before doing the glucose tolerance test, it is necessary to fast from food and water for 8 hours and measure the blood glucose on fasting, 1 hour and 2 hours after taking sugar. If one or more results are found to be abnormal, gestational diabetes is diagnosed. Therefore, it is necessary to strictly control the pregnant woman’s diet and to monitor her fasting blood sugar and blood sugar at 2 hours after meals. If the amniotic fluid is excessive, it may also cause respiratory distress in the pregnant woman. In this case, puncture to release some of the amniotic fluid may be considered.
