Abstract
BACKGROUND Placenta previa describes a placenta that is implanted somewhere in the lower uterine segment,either over or near the internal cervical os. AIM OF THE STUDY To analyse the risk factors and outcomes associated with placenta previa METHODS A prospective study of all the placenta previa patients delivered at Govt RSRM Lying in Hospital,Chennai from June 2019 to November 2020 are included.Control of 533 patients without placenta previa were selected randomly during the same period.The differences between the groups with respect to age,parity ,mal presentation,pregnancy associated complications,gestational age at onset of bleeding,gestational age at delivery,mode of delivery,third stage complications,neonatal outcome,during of hospital stay are noted. RESULTS The risk of occurrence of placenta previa is increased with advancing maternal age,parity and previous uterine surgery.Incidence is 0.5%,69% of placenta previa cases delivered by cesarean section,10% developed PPH,2% managed surgically,25% preterm delivery. CONCLUSION Accurate diagnosis,judicious expectant management with blood transfusion as required and timely delivery may lead to the most favorable outcome. The current study also suggested that advancing maternal age,parity and cesarean section increase the risk of placenta previa.
