118例胎儿生长受限相关因素分析

To analyse the correlative fators of 118 cases with fetal growth restriction

目的探讨胎儿生长受限(FGR)发生的相关因素。方法对足月FGR病例118例进行回顾性分析。结果118例FGR母体因素38例(32.2%),胎儿因素8例(6.8%),胎盘因素7例(5.9%),脐带因素36例(30.51%),无明确原因29例(24.8%);阴道分娩组新生儿窒息24例,占41.4%,剖宫产组新生儿窒息24例,占10.3%,两组分娩方式比较差异有统计学意义(P<0.0001)。结论①FGR的主要病因是母体因素,以妊娠并发症为首要因素,其中又以妊娠期高血压疾病占首位(13.9%),其次为脐带、胎盘因素,而病因不明者达20.4%;②及时恰当地治疗妊娠合并症和并发症,孕期进行干预治疗,选择恰当的分娩时机和分娩方式,有利于减少FGR胎儿窘迫和新生儿窒息的发生。适当放宽剖宫产指征,有利于降低FGR的后遗症。

Objective To discuss the correlative factors of fetal growth restriction(FGR).Methods 118 cases of FGR were retrospectively analyzed during the last five years in our hospital.Results Among 118 cases of FGR,there was 38(32.2%)cases who were caused by maternal factor,8(6.8%)cases by fetal factor,7(5.9%)cases by placental factor,36(30.51%)cases by umbilical cord factor,29(24.8%)cases by unknown factor.In vaginal childbirth group,there was 24(41.4%)cases with newborn asphyxia,and in the c-section group,there was 24(10.3%)cases with newborn asphyxia.There was significant difference between them(P<0.0001).Results ①The main cause of FGR is maternal factor in which the pregnant complications are the primary high risk factor.Among them,the hypertensive disorder complicating pregnancy accounts for 13.9% and it is the first place.Nextly,it is respectively the unbilical factor,the placental factor,and it accounts for with 20.4%;②It helps to decrease the incidence of fetal distress and neonate asphyxia that the complications and subsequent syndrome of pregnance were treated timely and rightly,and the intervening treatment was operated during the pregnancy.Broadening the index of c-section properly is advantageous of reducing the sequelas of FGR.
