Maternal and Perinatal Outcome in Premature Rupture of Membranes at Term Pregnancy

Background: Before onset of labour if premature rupture of membranes occurs, then it is called premature rupture of membranes. This study was conducted to evaluate the maternal and perinatal outcomes in term PROM cases. Materials and methods: This was a prospective study which was conducted during May 2015 to June 2016, on 75 cases of rupture of membranes spontaneously after 37 completed weeks who were admitted in department of obstetrics and gynaecology, Osmania Medical College, Hyderabad. Results: History of term PROM was seen in 15% of the patients, History of abortion was seen in 12% of the patients and history of preterm PROM was observed in 7% of patients. When risk factors and PROM were compared, anaemia was 20%, UTI was 10%, lower genital infections were 8%, cervical stich was 2%, mal-presentations were 4%, hydramnias were 4% and there were no risk factors in 27% of the patients. Favourable bishop score was observed 30 patients undergoing vaginal delivery, 10 in LSCS, and unfavourable bishop score was observed in 20 patients undergoing vaginal delivery, 9 in LSCS. Number of cases in maternal morbidity was highest in > 24 hours i.e. 26.7%, perinatal morbidity cases were highest in 12-24 hours i.e. 30% and mortality among perinatal cases were 5% in 12-24 hours and >24 hours of PROM. Conclusion: This study concluded that premature rupture of membranes incidence was higher in women of unbooked cases and in those with previous history of abortions and premature rupture of membranes. The concomitant increase in incidence of maternal morbidity and perinatal morbidity and mortality with an increase in the duration of labour and delivery and thus rate of caesarean delivery was increased.
