'Perinatal outcome in preterm premature rupture of membranes with Amniotic fluid index < 5 (AFI < 5).
BACKGROUND: Our purpose was to determine whether AFI<5 cm after preterm premature rupture of the membranes (PPROM) is associated with an increased risk of perinatal morbidity. METHODS: We performed a prospective cohort study of 95 singleton pregnancies complicated by preterm premature rupture of the membranes (PPROM) with delivery between 26 and 34 weeks gestation.Patients were categorized in two groups on the basis of amniotic fluid index<5, (AFI<5 cm)(n = 26) or AFI >/= 5 cm (n = 69). Categorical data were tested for significance with the chi2 and Fisher exact tests. Continuous data were evaluated for normal distribution and tested for significance with the student t test.All 2-sided p values < 0.05 were considered significant. RESULTS: Both groups were similar with respect to selected demographics, gestational age at rupture of the membranes, gestational age at the delivery, birth weight. Both groups were similar with respect to selected variable, latency until delivery, early onset neonatal sepsis, RDS and neonatal death. Patients with AFI<5 cm demonstrated greater frequency of C/S delivery for non reassuring fetal tests (23%vs 2.8%) (p = 0.001). Our study demonstrated that patients in group I had a significant increase in the frequency of clinical chorioamnionitis (P < 0/001). Post partum infections were not seen in 2 groups. CONCLUSIONS: An AFI<5 cm after PPROM between 26 and 34 weeks gestation is associated with an increased risk of maternal infections and frequency of C/S.
