Abstract:
Objective To investigate the risk factors of postpartum haemorrhage(PPH) in placenta previa. Methods A retrospective analysis of 136 cases with placenta previa from Jun.1996 to Dec. 2000 was performed. Results The incidence of placenta previa was 1.24%(136/10967) and the rate of postpartum haemorrhage was 22.06%(30/136). The associated factors of postpartum haemorrhage in placenta previa were history of multiple abortions (more than twice) , previous cesa rean section, elder age, type of placenta previa, no prenatal check, prenatal bleeding and other complications. PPH might happen when the high risk factor score was more than 4. Conclusions The relative factors of postpartum haemorrhage in placenta previa are abortions more than twice, previous cesarean section, older age, types of placenta previa, absence of prenatal check, antepartum hemorrhage and other complications. We can predict PPH by high risk factor score.
