Objective To analyze the perioperative condition of pregnant women of different types of placenta previa. Methods 90 cases of placenta previa pregnant women admitted and treated in our hospital during March 2012 and June 2015 were selected as the study objectives. All the targeted pregnant women’s clinical data were retrospectively analyzed. According to different types of placenta previa, the pregnant women were divided into complete placenta previa (CPP) group, partial placenta previa (PPP) group and marginal placenta previa (MPP) group with each group 30 cases. Compare the pregnant women’s bleeding conditions like perioperative bleeding and blood transfusion, complications occurrence rate including placenta implantation, adherent placenta and puerperal infection as well as the delivery gestational weeks. Results The amount of perioperative bleeding and blood transfusion in the CPP group were obviously higher than the PPP group and MPP group (P<0.05). The amount of bleeding in the MPP group was the least (P<0.05). The amount of postpartum bleeding in the MPP group was middle which was significantly different with the PPP group (P<0.05). The total occurrence rate of complications in the CPP group was 83.3% which was significantly higher than the PPP group (30.0%) and MPP group (20.0%). The difference was significant. The premature delivery (<36 weeks) occurrence rate in the CPP group was 73.3% which was significantly higher than the PPP group (33.3%) and MPP group (10.0%). The difference was significant (P<0.05). All the comparison showed statistical significance (P<0.05). Conclusion Different types of placenta previa all cause injury to the mother’s body. And the clinical symptoms for complete placenta previa are significantly worse than partial placenta previa and marginal placenta previa with less gestational weeks.
