彩色多普勒超声检测胎儿肾动脉血流用于胎儿宫内窘迫的预警效果

摘要

目的：分析讨论彩色多普勒超声检测胎儿肾动脉血流在预测胎儿宫内窘迫的临床效果，以期为临床应用提供指导依据。方法：遴选笔者所在医院2012年11月-2014年11月产检的孕晚期孕妇90例作为此次研究调查对象，根据胎儿是否存在宫内窘迫将其划分入两组，分别为有宫内窘迫45例(研究组)与无宫内窘迫45例(对照组)，两组孕妇均行彩超检测胎儿肾动脉血流，比较两组受试人员收缩期峰值流速与舒张末期流速比值(S/D)、搏动指数(PI)与阻力指数(RI)等，并观察不同窘迫程度胎儿上述三项指标的差异。结果：研究组胎儿的S/D、PI与RI均较对照组胎儿显著高(P<0.05)；轻度窒息胎儿的S/D、PI与RI均显著低于中度窒息者与重度窒息者，中度窒息者的上述三项指标以明显低于重度窒息者，比较差异均有统计学意义(P<0.05)。结论：应用彩色多普勒超声测定胎儿肾动脉血流有助于预测胎儿功能窘迫与其严重程度，对临床干预具有一定的指导作用，对降低围产儿死亡率、确保母婴健康具有十分积极的意义。%Objective:To analyze and discuss the clinical effect of fetal renal artery blood flow in the prediction of fetal distress by color Doppler ultrasound in order to provide guidance for clinical application.Method:90 pregnant women were selected as the research object from November 2012 to November 2014 in our hospital.According to the fetal distress,90 patients were divided into two groups,45 cases of fetal distress(the research group) and 45 cases of none fetal distress(the control group).The RI,PI and S/D of two groups were compared.Result:RI,PI and S/D in the research group were significantly higher than those in control group(P<0.05);the RI,PI and S/D in mild asphyxia were significantly lower than those in moderate and severe asphyxia,and those with moderate asphyxia were significantly lower than those with severe asphyxia(P<0.05).Conclusion:The application of color Doppler ultrasound in fetal renal artery blood flow can help predict fetal distress and its severity.It has a certain guiding role for clinical intervention.It has a positive significance to reduce the mortality of perinatal mortality and to ensure the health of mother and baby.
