Objective
To evaluate maternal and neonatal outcomes following management of preterm premature rupture of membranes (PPROM) by two fetal assessment strategies.
Methods
In a retrospective cohort study performed at two hospitals in Philadelphia, Pennsylvania between July 2010 and June 2015, data were reviewed from 180 singleton pregnancies with PPROM at 230–336 weeks of gestation that underwent expectant management. Outcomes were compared between continuous electronic fetal heart monitoring (EFM) with daily biophysical profile (BPP) (“continuous monitoring”) and non‐stress test (NST) three times per day (“periodic monitoring”) using Mann‐Whitney U and Fisher exact tests.
Results
Overall, 119 (66.1%) pregnancies were assessed by continuous monitoring and 61 (33.9%) by periodic monitoring. There was no difference in frequency of intrauterine death between the continuous monitoring (1, 0.8%) and periodic monitoring (3, 4.9%) groups (OR, 0.16; 95% CI, 0.02–1.61). The continuous monitoring group was more likely to have an interventional (OR, 2.17; 95% CI, 1.06–4.44) or cesarean (OR 3.30, 95% CI 1.70–6.38) delivery.
Conclusion
Continuous EFM with daily BPP was associated with higher rates of intervention and cesarean delivery compared with periodic NST, but there was no difference in intrauterine or perinatal mortality.
