ABSTRACT
OBJECTIVE:
Premature preterm rupture of membranes (PPROM) accounts for a significant part of overall perinatal mortality and morbidity. This study aims to define potential prognostic factors for neonatal outcome. PATIENTS ANDMETHODS:
One hundred and thirty-one pregnancies complicated with PPROM at between 26 and 32 weeks were retrospectively reviewed over a three-year period. The influence of chorioamnionitis on perinatal morbidity and mortality was assessed using a composite outcome.RESULTS:
On admission, gestational age (GA) at diagnosis, fetal heart rate anomalies and increasing severity of clinical features of chorioamnionitis were significantly related with an adverse outcome. Significant factors associated with a favourable outcome were an administration of steroids for lung maturation, prophylactic antibiotics and tocolytic therapies. Stratifying according to GA at PPROM, the survival rates were 43 and 52% at before 22 weeks and between 22 and 26 weeks respectively. The prognosis dramatically improved after 26 weeks with an 84.6% rate of survival without impairment. Although this rate reached 97.5% after 30 weeks, there was no statistical evidence supporting any benefit to prolong pregnancies beyond this point. The complete expression of chorioamnionitis independently increased the mortality rate by 41% (OR=1.41; 95% CI [0.99-2.01]. Overall, the most relevant factor was GA at delivery, levelling the prognostic value of GA at diagnosis. DISCUSSION ANDCONCLUSION:
If no consensus rules PPROM at the moment, the most efficient prognosis factor before 34 weeks is mostly determined by GA at delivery.
