摘要 目的:探讨静脉导管血流变化与慢性胎儿窘迫的关系。方法:将100例孕周为37~41周的孕妇分为两组:正常妊娠组及怀疑有慢性胎儿窘迫组,每组各50例。测定所有孕妇胎儿静脉导管血流参数(心室收缩期峰值,心室舒张期峰值,心房收缩期峰值,静脉导管的搏动指数、阻力指数),观察所有出生后新生儿1min Apgar评分、脐静脉血pH值、脐动脉血氧饱和度,研究静脉导管血流指数与它们的关系。结果:①慢性胎儿窘迫组静脉导管血流心室收缩期峰值,心室舒张期峰值,心房收缩期峰值均低于正常妊娠组,而静脉导管的搏动指数、阻力指数均高于正常妊娠组,差异具有统计学意义(P<0.05)。②慢性胎儿窘迫组新生儿体重、Apgar评分、脐静脉血pH值及脐动脉血氧饱和度均低于正常妊娠组,差异具有统计学意义(P<0.05)。③静脉导管血流指数与新生儿出生体重,Apgar评分,脐静脉血pH值及脐动脉血氧饱和度之间呈负相关性。结论:慢性胎儿窘迫时胎儿静脉导管血流参数发生变化。监测胎儿静脉导管血流变化可预防不良妊娠结局发生。 Objective: To explore the relationship between ductus venosus blood flow and chronic fetal distress. Methods: 100 pregnant women (gestational weeks: 37 - 41 weeks) were divided into two groups: control group (50 cases) and chronic fetal distress group (50 cases) . All fetal ductus venosus blood flow parameters including ventricular systole, ventricular diastole, atrial systole, pulsatility index, resistance index were observed. All the neonatal outcomes including body weights, 1 minute Apgar scores, pH values of umbilical vein, oxygen saturation of umbilical artery were observed. Results: (1)The peak values of ventricular systole, ventrieular diastole and atrial systole in chronic fetal distress group were lower than those in control group, while pulsatility index and resistance index reversed (P 〈 0. 05) . (2)The body weight of neonates, Apgar score, pH value of umbilical vein and oxygen saturation of umbilical artery in chronic fetal distress group were lower than those in control group ( P 〈 0. 05 ) . (3)There was negative correlation between ductus venosus blood flow parameters and body weight of neonates, Apgar score, pH value of umbilical vein, oxygen saturation of umbilical artery. Conclusion: The ductus venosus blood flow parameters change in children with chronic fetal distress, the monitoring of ductus venosus blood flow parameters can prevent bad perinatal outcomes.
