Abstract: To investigate perinatal diagnosis of oligohydramnios and outcome of perinatal fetus methods 202 cases of oligohydramnios were reviewed. The incidence of oligohydramnios, from January, 1988 to July, 1998, was 1.47%(202/13 738). The prolonged pregnancy was 52.48 % (106/202). IUGR, EPH syndrome and prolonged pregnancy were common complications. The accordance rate that ultrasonography diagnosed oligohydramnios was 72.77%(147/202). The incidence of fetal distress and asphyxia neonatorum were 44.55%(90/202) and 2.48%(5/202) respectively. The death rate of perinatal fetus was 0.99%(2/202). The cesarean section rate was 92.08%(186/202). The result showed that ultrasonography is a simple and effective method diagnose oligohydramnios in the period of gestation. Early diagnosis and quickly performed ceasarean section is the key to improve the outcome of perinatal fetus of oligohydramnios.

Key words: oligohydramnios, fetal distress, asphyxia neonatorum
