Abstract: During normal pregnancy，the production and absorption of amniotic fluid is in dynamic balance. Abnormal amniotic fluid volume is closely related to maternal and fetal complications，which directly endangers the safety of perinatal infants. According to the etiology of abnormal amniotic fluid volume，gestational age，the severity of maternal symptoms and the conditions of the fetus in utero，adopting appropriate methods of labor induction based on indications is of great significance to improve the outcome of perinatal infants.
