Clinical Analysis of 52 Gravidas with Placenta Praevia

Abstract

Objective To investigate the relationship between different degrees of placenta praevia and clinical outcomes. Methods From July 2009 to July 2013, a total of 52 patients with placenta praevia were included in the study. They were divided into total placenta praevia group(n=20), partial placenta praevia group(n=15) and marginal placenta praevia group(n=17). The study protocol was approved by the Ethical Review Board of Investigation in Human Being of Fifth People's Hospital of Chengdu.Informed consent was obtained from each patients. Results The incidence rate of placenta praevia was 2.03%(52/2 565). Statistical differences were found among three groups in the gestational weeks at first bleeding, diagnosis and delivery(t=8.53, 7.78, 6.79, 6.51, 5.36, 4.79; P<0.05). The blood loss and cesarean section rate were obviously higher in total placenta praevia group than those of partial placenta praevia group and marginal placenta praevia group(t=12.93, 15.35, 7.56, 6.78; P<0.05). There also had significant differences in birth weight among three groups(t=10.35, 11.01; P<0.05). Conclusions Compared with partial and marginal placenta praevia, clinical outcomes of patients with total placenta praevia are much worse. The diagnosis of placenta praevia as early as possible could help us to evaluate the patients' condition and provide guidance of clinical management, and finally obtain good clinical outcomes.
