不同类型胎盘前置状态对妊娠结局的影响

The Influence of Different Types of Placenta Previa on Pregnancy Outcome

目的研究不同类型胎盘前置状态对妊娠结局的影响。方法选取我院胎盘前置孕妇119例作为观察组,其中边缘型胎盘前置66例,部分型胎盘前置18例,中央型胎盘前置35例,另选同期产检正常孕妇110例作为对照组。比较两组临床特征,并比较不同类型胎盘前置孕妇妊娠结局及新生儿结局。结果两组受教育程度、产次无明显差异(P> 0.05);观察组剖宫产史、吸烟史、流产史、贫血、早产史发生率高于对照组,年龄、孕次高于对照组(P <0.05);中央型胎盘前置孕妇终止孕周较边缘型胎盘前置、部分型胎盘前置孕妇短,胎盘植入、胎盘粘连、剖宫产、早产、子宫切除、产后出血发生率高于边缘型胎盘前置、部分型胎盘前置孕妇(P <0.05);中央型胎盘前置新生儿阿氏(Apgar)评分、出生体质量低于边缘型胎盘前置、部分型胎盘前置(P <0.05)。结论年龄、剖宫产史、吸烟史、流产史、孕次、贫血、早产史是胎盘前置发生的影响因素,不同类型胎盘前置状态对妊娠结局、新生儿结局均具有不良影响,以中央型胎盘前置最为严重,需及早防治。

Objective To study the influence of different types of placenta previa on pregnancy outcome. Methods 114 pregnant women with placenta previa in our hospital were selected as observation group, including 40 cases of marginal placenta previa, 38 cases of partial placenta previa, 36 cases of complete placenta previa, and 110 cases of normal pregnant women in the same period as control group. The clinical characteristics of the two groups, the pregnancy outcomes and neonatal outcomes of pregnant women with different types of placenta previa were compared. Results There was no significant difference in education level and delivery times between the two groups(P >0.05). The incidence of cesarean section history, smoking history, abortion history, anemia and preterm birth history in the observation group was higher than that in the control group, and the age and pregnancy times were higher than those in the control group(P <0.05). The gestational weeks of termination of complete placenta previa were shorter than that of marginal placenta previa and partial placenta previa. Placenta implantation, Placenta Adhesion and cesarean section, premature delivery, hysterectomy and postpartum hemorrhage were higher than that of marginal placenta previa and partial placenta previa(P <0.05). Apgar score and birth weight of complete placenta previa neonates were lower than that of marginal placenta previa and partial placenta previa(P <0.05). Conclusion Age, cesarean section history, smoking history, abortion history, pregnancy times, anemia and premature birth history are the influencing factors of placenta previa. Different types of placenta previa have adverse effects on pregnancy outcomes and neonatal outcomes. Complete placenta previa is the most serious and needs early prevention and treatment.
