摘要
目的研究四种类型前置胎盘的临床特点,以及各胎盘类型对妊娠结局的影响。方法选取我院2015年6月至2018年6月收治的99例前置胎盘孕妇为研究对象,根据其前置胎盘类型,将其分为四组,低置前置胎盘孕妇为A组(21例),边缘性前置胎盘孕妇为B组(23例),部分性前置胎盘孕妇为C组(39例),完全性前置胎盘孕妇为D组(16例)。观察并比较四组孕妇的临床特点、妊娠结局及其对新生儿的影响。结果四组孕妇的临床特点各有差异,胎盘与宫颈内口的相对位置不同,且初次出血发生时间也有不同。四组孕妇产前出血、产后输血及接受抑制宫缩治疗的发生率比较,差异具有统计学意义(P<0.05);四组孕妇产后出血发生率、新生儿体重及1、5 min Apgar评分比较,差异无统计学意义(P>0.05)。四组孕妇休克、胎盘粘连、胎盘植入、剖宫产及子宫切除等不良妊娠结局发生率比较,差异无统计学意义(P>0.05)。四组新生儿早产和窒息发生率比较,差异具有统计学意义(P<0.05);低体重和死亡发生率比较,差异无统计学意义(P>0.05)。结论四种前置胎盘类型均具有独特的临床特点,均会对孕妇与新生儿产生一定的不良影响,应采取一定的防范措施。
Objective To study the clinical characteristics of four types of placenta previa and their influences on pregnancy outcomes.Methods Ninety-nine pregnant women with placenta previa admitted in our hospital from June 2015 to June 2018 were selected as research objects.According to the type of placenta previa,they were divided into four groups,with low placenta previa were group A(21 cases),marginal placenta previa were group B(23 cases),partial placenta previa were group C(39 cases),and complete placenta previa were group D(16 cases).The clinical characteristics,pregnancy outcomes and their effects on newborns of the four groups were compared.Results The clinical characteristics of four groups of pregnant women were different,the relative positions of placenta and cervical internal orifice were different,and the time of the first bleeding were also different.The incidences of prenatal hemorrhage,postpartum blood transfusion and inhibited uterine contraction in the four groups were significantly different(P<0.05).There were no significant differences in the incidences of postpartum hemorrhage,neonatal weight and Apgar scores at 1 and 5 min among the four groups(P >0.05).There were no significant differences in the incidences of adverse pregnancy outcomes such as shock,placental adhesion,placental implantation,cesarean section and hysterectomy among the four groups(P >0.05).There were significant differences in the incidences of premature birth and asphyxia among the four groups(P<0.05),and there were no significant difference in the incidences of low birth weight and death(P >0.05).Conclusion The four types of placenta previa have their own unique clinical characteristics,which will have certain adverse effects on pregnant women and newborns,and some preventive measures should be taken.
