Oligohydramnios is an independent risk factor for perinatal morbidity among women with pre-eclampsia who delivered preterm

AbstractPurpose: The purpose of this study is to determine the relationship between oligohydramnios and adverse maternal and neonatal outcomes in a unique cohort of preterm pre-eclamptic patients.Materials and methods: A retrospective matched case–control study comparing 81 preterm parturients (28 0/7 and 36 6/7 weeks) with pre-eclampsia and oligohydramnios to 81 preterm pre-eclamptic patients with a normal amniotic fluid index (AFI).Results: About 4.8 percent of all our preterm pre-eclamptic patients had oligohydramnios. Patients in the study group showed a trend toward being older than 35 years (18.5%% versus 27.2%) and were more likely more likely to be primi-parous, and have previously delivered a small for gestational age (SGA) or a dead fetus (p = .012, .039, and .032). Severity of pre-eclampsia, including HELLP and eclampsia as well as gestational age at delivery did not differ statistically between the study groups (p = .47, .516). Growth restricted fetuses were more common in the study group (p <...
