“…Prematurity as a neonatal complication has been reported in earlier studies also. [11][12][13][14] According to RCOG guidelines elective delivery by caesarean section in asymptomatic women is not recommended before 38 weeks of gestation for placenta previa or before 36-37weeks for placenta accreta. 17 No significant association between the APGAR score and type of placenta previa was found in our study.…”

Background: The reported incidence for placenta previa averages 0.3% or 1 case in 300 to 400 deliveries. Multiparity, advanced maternal age, cigarette smoking, previous caesarean delivery, history of abortions or uterine surgical procedures are some of the risk factors contributing to the development of placenta previa. Massive obstetrical haemorrhage in placenta previa is associated with severe maternal morbidity and mortality. A significant number of mothers can be saved if right approach of management is followed in placenta previa.Methods: The present case study is a retrospective analysis carried out in a tertiary care centre to study the risk factors and maternal and perinatal outcome in cases of placenta previa. The study included antenatal patients diagnosed as placenta previa on sonography at or >26 weeks of pregnancy. Data was compiled and statistically analysed.Results: Incidence of Placenta Previa in our study was 0.54%. 73.2% patients had history of previous cesarean sections. 53.6% patients were referred from outside. 98.2% patients delivered by caesarean section. Obstetric hysterectomy was required in 3.5% of total cases. 10.7% cases required the ICU admission after delivery. There was no maternal mortality in the study group. The mean gestational age at delivery was 35±2.4weeks. The mean APGAR at 5 min was 9±2.2.Conclusions: Increasing rates of caesarean sections in present era indicate that incidence of Placenta Previa is expected to rise. Good antenatal care, availability of emergency obstetric services, infrastructure, blood bank facility, HDU and ICU care and NICU services can improve maternal and neonatal outcome.

PURPOSE:To compare the maternal and perinatal outcomes of patients with placenta previa, after the adoption of a prolonged maternal hospital stay, to those of a 1991 series. METHODS: We performed a retrospective study comparing 108 cases of placenta previa hospitalized in the Maternity School Assis Chateaubriand, Universidade Federal do Ceará, during the period from 01/01/2006 to 12/31/2010, with those obtained in 1991, when 101 cases of the pathology were observed at our institution. The following maternal and perinatal data were collected: maternal age, parity, gestational age at delivery, mode of delivery, maternal stay length, Apgar scores at the 1 st and 5 th minutes, birth weight, adequacy of birth weight, neonatal length stay, maternal and neonatal morbidity and mortality rates (maternal, fetal, neonatal and perinatal). Statistical analysis was performed using the χ 2 and Fisher's exact tests. The results were considered significant when p<0.05. RESULTS: In 1991, placenta previa was found in 1.13% of cases (101/8900). In the present study, the prevalence was 0.43% (108/24726). No maternal death was observed in either series. Regarding the study of 1991, the current patients were significantly younger, with lower parity, were hospitalized longer, had better Apgar scores at 1 st and 5 th minutes, and had longer neonatal hospitalization. Also, we identified reduction of fetal, neonatal and perinatal mortality. CONCLUSIONS: Perinatal outcomes in patients with placenta previa were significantly improved between 1991 and the years 2006 and 2010. However, we can not say whether this improvement was due to the prolonged maternal hospital stay.

“…4 Furthermore, the risks of maternal mortality and neonatal complications appear to be increased in the setting of placenta previa as well as accreta. 5,6 Thus, given the strong association between multiple cesarean deliveries and placenta previa and accreta, 7 it is not surprising that this rise is being seen.…”
