目的探讨胎儿生长受限(FGR)危险因素的孕期分布、对预后的影响及相关关系等特征。方法回顾性分析46例出生体质量<2 500g的低体质量儿及引产病例,对其妊娠期胎儿、母体及胎儿附属物三类危险因素进行随访研究。结果中孕期FGR组与晚孕期FGR组之间危险因素构成及新生儿预后情况均具有显著差异(均P<0.05),母体因素例如妊娠期高血压疾病与羊水量和脐动脉血流搏动指数等胎儿附属物因素之间无明显差异(P>0.05)。结论胎儿生长受限危险因素对其分期和预后有重要影响。妊娠期系统超声筛查及序贯监测胎儿生长发育情况对胎儿生长受限的诊断及治疗具有重要价值。
Objective To investigate the distribution of fetal growth restriction (FGR) risk factors during pregnancy, the prognosis and related characteristics. Methods A retrospective analysis of 46 cases of low birth weight children with birth weight <2 500 g and cases of induced labor was conducted to investigate the risk factors of fetal, maternal and fetal appendages during pregnancy. Results There were significant differences in the risk factors between the FGR group and the FGR group in the second trimester (P <0.05), and the prognosis of the neonates (P <0.05). Maternal factors such as gestational hypertension, amniotic fluid volume and umbilical artery pulsatile index There was no significant difference between fetal appendages (P> 0.05). Conclusion The risk factors of fetal growth restriction have an important influence on the staging and prognosis. Ultrasound screening of pregnancy system and sequential monitoring of fetal growth and development of fetal growth restriction diagnosis and treatment of great value.
