Maternal characteristics and timing of presentation following pre-labour rupture of membranes

MANAGEMENT OUTCOME OF PREMATURE RUPTURE OF MEMBRANES IN A TERTIARY HEALTH FACILITY IN SOUTH WESTERN NIGERIA

Background

Pre-labour Rupture of Membranes (PROM) contributes immensely to the potential risk of maternal morbidity and mortality.

Objective

To explore the incidence and management outcome of PROM at Ladoke Akintola University of Technology Teaching Hospital (LTH), Ogbomoso, Nigeria.

Methods

A retrospective study of 61 cases of PROM managed at LTH, Ogbomoso over a 3-year period. Information on the socio-demographics and obstetrics characteristics, management instituted, and outcomes were obtained using a structured proforma. Data were analysed using SPSS version 20. Level of statistical significance was set at <0.05 and 95% confidence interval.

Results

The incidence of PROM was 4.1% with a perinatal mortality rate of 0.18 per 1000 deliveries. Twenty (33%) were pre-term while 41 (67%) were term PROM with 10% of the perinatal death occurring among those with preterm PROM. The mean age of the women was 36.9 (SD=2.1) years and median parity of 1(range 1-5) children. There was a significant association between the women's gestational age at which PROM occurred with the latency period (p< 0.001). Fetal birth weight, APGAR score and Neonatal Intensive Care Unit (NICU) admission were all significantly associated with the gestational age at which PROM occurred (p<0.05). There was a significant difference between the intervention instituted and mode of delivery (p=0.009).

Conclusion

The incidence of PROM at term was high and conservative/ expectant management was effective. The latency period and fetal outcomes such as birth weight, apgar score and NICU admission were determined by the gestational age at which PROM occurred.
