Clinical analysis of 145 oligohydramnios

Objective To investigate the diagnose and management of oligohydramnios.Methods 145 cases of oligohydramnios from Jan.2000 to Dec.2000 were clinically analysed retrospectively.Results The rate of oligohydramnios was 3.8%,oligohydramnios occurred frequently in a term gestation.Degree of oligohydramnios was correlated with neonatal saphyxia and perinatal prognosis.Using amniotic fluid index measured by B ultrasonic,the correct rate was 95.2%,for higher risk pregnancy or someone who incorporate with wevere oligohydramnios,caesarean section should be the first choice.If there was only oligohydramnios and no higher risk factors were found during gestation,natural delivery under strict ward should be the first choice.Conclusion Amniotic fluid index measured by B ultrasonic should be a credible method for discovering oligohydramnios.Caesarean section is a safe delivery mode.
