Abstract:
Objective To explore the influential factors of dangerous placenta previa pathogenesis,and to analyze their peri natal period outcomes.Methods The clinical data in 143 pregnant women and parturients of dangerous placenta previa(research group) and 286 pregnant women and parturients of non-dangerous placenta previa(control group) in our hospital from January 2011 to December 2015 were retrospectively analyzed.Results The average age of the research group was higher than that of the control group (t =2.92,P =0.004);the previous pregnancy frequency,previous parity,previous abortion frequency,previous cesarean delivery frequency and incidence of placenta previa in the research group were higher than those in the control group(P<0.01);the incidence of placenta previa in the research group was higher than that in the control group(x2 =7.60,P=0.006);the prenatal gestational weeks of the research group were lower than those of the control group(t=-12.33,P<0.01).The multi-factor analysis showed that the age,previous abortion frequency and previous cesarean delivery frequency were the influence factors of placenta previa occurrence.Among them,the previous cesarean delivery frequency was the main risk factor.The occurrence rates of antepartum hemorrhage,postpartum hemorrhage,uterine removal and premature infants in the research group were higher than those in the control group(P<0.01);The intraoperative blood loss of the research group was higher than that of the control group(P<0.05);the neonatal birth weight and the 1 min Apgar score of the research group were lower than those in the control group(P<0.05).Conclusion The age,previous abortion frequency and previous cesarean section frequency are related to the occurrence of dangerous placenta previa.
