How much amniotic fluid is normal at eight months needs to look at the amniotic fluid inspection index, including amniotic fluid index, vertical depth of amniotic fluid, amniotic fluid volume, etc. The normal range is as follows: 1. If it is higher than 8cm, it is too much amniotic fluid; 3, the amount of amniotic fluid: the normal amount is about 800ml, if the amniotic fluid exceeds 2000ml, it is too much amniotic fluid, less than 300ml is called too little amniotic fluid. When the amniotic fluid is too small, the fetal activity is restricted, suggesting that there may be fetal malposition, fetal lung insufficiency, fetal malformation, and even limb shortage, and the incidence of fetal distress and neonatal asphyxia is also higher. When there is too much amniotic fluid, the fetus is prone to preterm delivery, premature rupture of membranes and abnormal fetal position, while the pregnant woman is prone to complications of hypertension, placental abruption and umbilical cord prolapse during rupture of membranes, and postpartum hemorrhage during delivery. The clinical method of amniotic fluid index is usually used to determine the amniotic fluid volume. When abnormal amniotic fluid volume is found, it is necessary to go to the hospital in time to improve the relevant examination and find out the cause before carrying out symptomatic treatment. Low amniotic fluid can be treated with expectant therapy and, if necessary, termination of pregnancy. Excessive amniotic fluid can be self-regulated within a short period of time, or can be treated with medication under the guidance of a doctor.
