目的探讨脐动脉血流监测在妊娠期糖尿病孕妇(GDM)的实际应用的效果。方法随机抽取100例正常孕妇作为对照组,随后抽取100例患有妊娠期糖尿病孕妇作为观察组,同时进行脐动脉血流检测,记录脐动脉血流速率在收缩末期与舒张末期的比值(SD值),随后对其进行阻力指数与搏动指数的测量。并与该孕妇分娩时期发生胎膜早破、产后出血、巨大儿、围生儿的结局的数据进行整理分析。结果观察组孕妇S/D值、阻力指数与搏动指数都明显高于对照组,差异有统计学意义(P<0.05)。观察组胎膜早破、产后出血、巨大胎儿、围生儿等的发生率也高于正常孕妇,差异有统计学意义(P<0.05)。在妊娠期糖尿病孕妇中的早产、胎盘异常、脐带异常等数据也高于正常孕妇,差异有统计学意义(P<0.05)。结论对孕妇进行脐动脉血流监测,特别是对于妊娠期糖尿病孕妇,能及时发现胎儿的异常情况,能有效地了解胎盘的功能、预测围生儿预后一种敏感、有效的监护手段。当妊娠期糖尿病孕妇的S/D值>2.5时,要警惕胎儿的健康情况,防止出现早产、胎儿发育不良、围产预后不良等结局发生。
Objective To investigate the effect of umbilical artery blood flow monitoring in pregnant women with gestational diabetes mellitus (GDM). Methods 100 normal pregnant women were randomly selected as the control group. Then, 100 pregnant women with gestational diabetes mellitus were selected as the observation group. At the same time, the umbilical artery blood flow was measured and the ratio of umbilical artery blood flow velocity at end-systole to end-diastole (S D value), followed by its resistance index and pulsatility index measurement. And with the pregnant women during childbirth premature rupture of membranes, postpartum hemorrhage, macrosomia, perinatal outcome data were analyzed. Results The S / D value, resistance index and pulsatility index of pregnant women in observation group were significantly higher than those in control group (P <0.05). The incidence of premature rupture of membranes, postpartum hemorrhage, huge fetus, perinatal children in observation group were also higher than those in normal pregnant women, the difference was statistically significant (P <0.05). The data of prematurity, placental abnormality and umbilical cord abnormality in pregnant women with gestational diabetes were also higher than those of normal pregnant women, the difference was statistically significant (P <0.05). Conclusion The monitoring of umbilical artery blood flow in pregnant women, especially for pregnant women with gestational diabetes mellitus, can detect fetal abnormalities in time and can effectively understand the function of the placenta and predict the prognosis of perinatal children. It is a sensitive and effective means of custody. When pregnant women with gestational diabetes S / D value> 2.5, we must guard against the health status of the fetus to prevent premature birth, fetal hypoplasia, perinatal poor prognosis and other outcomes.
