Maternal and Neonatal Outcomes of Preterm Premature Rupture of Membranes before Viability
Background: To investigate maternal and neonatal outcomes of previable preterm premature rupture of membranes (PPROM) and compare outcome between previable PPROM before and after 20 weeks of pregnancy, with data from one single center.
Patients: All women with singleton or twin pregnancies, from 2002 through 2011, who presented with PPROM before 24 weeks of gestation.
Method: A retrospective cohort study in a university teaching hospital in the Netherlands. Data were analyzed and compared between pregnancies with previable PPROM before and after 20 weeks of pregnancy. Main outcome measures were maternal and neonatal morbidity and mortality.
Results: A total of 160 women (164 fetuses) were included. 90 women (56.2%) developed complications (intra-uterine infection, retained placenta, placental abruption or sepsis). There was no maternal mortality. 68 neonates were admitted after birth. PPHN (64.7%, p=0.001) and contractures (58.8%, p<0.001) occurred significantly more in neonates born after PPROM<20 weeks of pregnancy. Eventually 38.4% of the neonates survived. Neonates born after previable PPROM > 20 weeks had a greater likelihood of being alive at discharge (22.7 vs. 46.9%, p=0.008).
Discussion: This study of previable PPROM shows that more than 50% of the mothers develop one or more complications. Neonates have a high mortality rate, especially neonates born after PPROM<20 weeks of pregnancy. In particular neonates born after PPROM<20 weeks of pregnancy should be watched closely for PPHN and contractures.
Conclusion: This large single center study can provide good foundation for counseling parents on previable PPROM, especially the prognosis of PPROM<20 weeks of pregnancy is of additional value.
