目的本实验主要研究胎儿静脉导管(DV)血流量与脐静脉(UV)血流量比与围产儿预后的关系。方法通过彩色多普勒超声检测晚期妊娠胎儿的DV与UV的血流参数,分别储存图像、记录数据并计算静脉导管血流量与脐静脉血流量比,进行统计学分析。结果围产儿不良结局时静脉导管的血流量与脐静脉血流量比(DVQ/UVQ)显著增加。结论静脉导管与脐静脉血流参数可作为判断围产儿预后的一项重要指标,对指导围产医学具有一定的临床价值。
Objective This study was to investigate the relationship between fetal venous catheter (DV) blood flow and umbilical vein (UV) blood flow ratio and prognosis of perinatally. Methods The blood flow parameters of DV and UV in fetus of late pregnancy were detected by color Doppler sonography. The images were stored, the data were recorded and the ratio of venous catheter blood flow to umbilical vein blood flow was calculated. Results Venous catheter blood flow and umbilical venous blood flow ratio (DVQ / UVQ) were significantly increased in poor outcome. Conclusions The parameters of venous catheter and umbilical vein blood flow can be used as an important index to judge the prognosis of perinatal and have certain clinical value in guiding perinatal medicine.
