足月胎儿生长受限的妊娠结局

Pregnancy Outcome of Term Fetal Growth Restriction

目的:探讨胎儿生长受限(FGR)的主要相关因素,终止妊娠的方法和时机,改善FGR围生儿预后。方法收集近5年的足月FGR病例108例,分析FGR孕妇有关病史、妊娠经过、分娩方式、妊娠结局和相关因素。结果:①与FGR相关因素方面,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%),其次为胎盘、胎儿因素,而病因不明者达20·4%。②阴道分娩组与选择性剖宫产组比较,胎儿窘迫率和新生儿窒息率均有显著性差异(P<0·01)。③108例足月FGR新生儿体重为(2250±225)g。结论:妊娠并发症是FGR主要危险因素,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。

Objective： To investigate the risk factor of fetal growth restriction （ FGR）, evaluate the mode and the timing of delivery, and analyze fetal prognosis in FGR. Methods： 108 patients with FGR were studied respectively. Results： ①The pregnant complications are the primary high risk factor for the term FGR in this area, among them accounting for the first place with hypertensive disorder complicating pregnancy （ 13.9% ） . Secondly it is abnormalities of placenta, fetal problems. A precise etiology is unidentified in 20. 4 percent cases of the term FGR. ②There are significant differences between vaginal delivery group and elective cesarean section group of the incidence of fetal distress and neonate asphyxia （ P 〈 0. 01 ） . ③The mean neonate＇s weight of 108 term FGR is 2 250 ± 225 grams. Conclusion： It is pregnant complications that are the main risk factors for FGR in this area. The timing of delivery is crucial. In the severely growth - restricter fetus, elective cesarean section is the preferred.
