To investigate the incidence of oligohydramnios in each gestational week, with or without other risk factors, mode of delivery and perinatal outcome. Methods: From January 1993 to December 1997, the incidence of oligohydramnios was 15 68 cases, oligohydramnios occurred 40 weeks to 41 6 weeks 53 16% (84/158), 59 cases High-risk pregnancies with oligohydramnios occurred more than 40% of the patients (40%, 41/51) before 40 weeks. B-ultrasound was used as an indicator to monitor amniotic fluid, with a coincidence rate of 95.47%. Results: Cesarean section ended as soon as possible delivery can significantly improve the prognosis of perinatal children, 15 cases of fetal distress 57 cases of low Apgar in 11 cases, no case of perinatal death.
