ABSTRACT

Abstract:The aim of this study was to investigate risk factors and perinatal outcomes of pregnancies complicated by placenta praevia. Records of 148 cases with placenta praevia and 1480 randomly selected controls were reviewed retrospectively. Statistical analysis was performed using Pearson’s chi square method. Placenta praevia complicated 1.3% (n= 148) of all deliveries included in the study (n= 11200). Multiparity was more common in patients with placenta praevia (78.5%, p<0.001). Cases with placenta praevia had majority of male infants – 94(63.5%). Cases with placenta praevia had significant low birth weight babies (< 2500gm) – 33% , p<0.0001. It was also concluded from the study that previous abortion (OR= 0.6; 95% CI = 0.57-0.83), previous placenta praevia (OR= 4.17; 95% CI= 5.61-7.62) and previous cesarean section (OR= 9.5%; 95% CI= 3.9- 33.41) were risk factors for placenta praevia. Significant number of newborns that were delivered after placenta praevia graded had lower apgar scores less than 7 at 5 min (24.7%, p<0.0001). Multiparity, previous placenta praevia, previous abortion and previous cesarean section are concluded as significant risk factors for placenta praevia..
