摘要
目的探讨应用脐带多项指标评估胎儿宫内生长发育状况及新生儿体重的临床价值。方法2 0 0 0年2月至2 0 0 2年6月间河北医科大学附属第四医院产前经多普勒超声测量脐带、脐动脉、脐静脉直径,脐动脉血流参数,脐静脉流速,并与胎龄比较。产后测量脐带长度、直径、脐带扭转周数,脐血生长激素(GH)、微量元素含量。根据正常新生儿体重分为大、中、小3组,分别与所测指标进行比较。结果脐带、脐动脉、脐静脉直径随胎龄生长而持续增长,并与新生儿体重呈正相关。脐动脉血流参数随胎龄增长而逐渐降低。胎儿脐静脉血流量孕4 0周时为80mL/ (min·kg)。脐带长度与脐带直径、胎儿体重无关。脐带长度与扭转周数有关,与脐带绕颈绕身有关。脐血中GH含量与新生儿体重有关,微量元素与新生儿体重无关。结论产前应用脐带多项指标评估胎儿宫内生长发育状况及体重有临床价值。
Objective To evaluate the clinical value of fetus' growth and newborns' weight assessed by umbilical cord indices.Methods From February,2000 to June,2002,in the Fourth Hospital of Hebei Medical University,pregnant women were detected by high frequency color Doppler ultrasonography.The diameter of umbilical cord、umbilical artery and umbilical vein, flow indices of umbilical artery and flow velocity of umbilical vein were measured to investigate the relationships between them and gestational age.The newborns were divided into three groups by their birth weight;in addition,all the umbilical cord's length,diameter and numbers of coils,growth hormone(GH),contents of microelement in umbilical blood were recorded and detected.Results The diameters of umbilical cord,umbilical artery and umbilical vein were growing in pace with gestational age,which was positively related to the birth weight.The blood flow indices of umbilical artery went down continuously.In 40 weeks' gestation,the index of fetal umbilical vein blood flow was ~80mL/(min·kg) . There was no correlationship between umbilical cord length,diameter and birth weight.There was a close correlation between umbilical cord length,the numbers of umbilical cord coils and cord entanglement.The newborns' weight was related to the contents of GH of umbilical blood,but not the microelements.Conclusion It is very valuable to evaluate the fetus' growth and newborns' weight by umbilical cord indices.
