Comparison of the Fetomaternal Outcome in Women With Preterm Premature Rupture of Membranes on Expectant Management Versus Delivery at 34 Weeks.

CONTEXT

This study aimed to study feto-maternal outcomes in women with preterm prelabor rupture of membranes (PTPROM) on expectant management versus delivery at 34 weeks of gestation and correlate the period of latency and inflammatory markers with delivery outcomes. We have chosen this research topic as there is a paucity of specific guidelines regarding the optimal period of gestation for delivering women with PTPROM.

AIM

The study correlated the feto-maternal outcomes in women with PTPROM on expectant management till 37 weeks versus delivery at 34 weeks with a period of latency and maternal inflammatory markers.

METHODS AND MATERIALS

This was a prospective observational study conducted on 262 women with PTPROM from 28-33+6 weeks of gestation. Women were monitored till 37 weeks with biweekly total leukocyte count and weekly C-reactive protein, urine routine microscopy, urine culture, high vaginal culture sensitivity, and ultrasound. Women were monitored expectantly till 37 weeks. However, intervention was done at any time during the feto-maternal compromise. There were 52 women who delivered <34 weeks and 210 women who delivered ≥34 weeks. Feto-maternal outcomes were documented. Group A was assigned to women who delivered before 34 weeks and Group B was assigned to women who delivered after 34 weeks. Statistical analysis was done using SPSS software. A p-value <0.05 was considered significant.

RESULTS

Among the study group, 238 (90.8%) women were managed expectantly while 24(9.1%) required intervention. A latency of 3-4 weeks was observed in 131(50%) women. Chorioamnionitis developed in 7 women (4.4%) in group A and 13 women (4.9%) in group B. Neonates developed sepsis in 5.7% in group A and 5.8 % in group B and were comparable in both the groups (p=1.000). Early neonatal death (END) occurred in 10 (3.8%) among which seven died because of low birth weight (LBW), two due to sepsis, and one due to respiratory distress. LBW was significantly associated with END (p<0.001) Conclusion: Expectant management beyond 34 weeks with close monitoring can improve neonatal outcomes without increasing maternal morbidity in women with PTPROM.
