目的探讨多普勒超声对妊娠期高血压患者子宫动脉血流的检测情况。方法选择我院2015年2月至2016年2月我院接诊的80例妊娠期高血压患者作为观察组,并选择同期我院接诊的80例正常妊娠产妇作为对照组。使用美国GE Voluson E8超声多普勒血流检测仪,比较两组子宫动脉血流及妊娠结局;并根据是否出现舒张早期切迹将观察组分为切迹组和无切迹组,比较两组妊娠结局。结果观察组阻力指数、搏动指数、收缩-舒张流速比值均比对照组高[(0.59±0.06)vs(0.51±0.03),(0.95±0.18)vs(0.72±0.12),(2.47±0.52)vs(2.01±0.31)],差异均具有统计学意义(P<0.05);观察组新生儿体重明显低于对照组,早产、剖宫产、胎儿窘迫明显高于对照组,差异均具有统计学意义(P<0.05);在观察组中,舒张早期切迹发生率为45.00%(36/80),切迹组新生儿体重明显低于无切迹组,早产、羊水异常、胎儿窘迫发生率均明显高于无切迹组,差异均具有统计学意义(P<0.05)。结论在妊娠期高血压患者中应用多普勒超声检测子宫动脉血流动力学有助于预测不良妊娠结局,临床应用价值高。
Objective To investigate the detection of uterine arterial blood flow in patients with hypertensive disorder complicating pregnancy by Doppler echocardiography. Methods 80 cases of hypertensive patients with gestational hypertension treated in our hospital from February 2015 to February 2016 were selected as the observation group and 80 normal pregnant women receiving the same period of our hospital as the control group. The US GE Voluson E8 Doppler flowmeter was used to compare the uterine artery blood flow and pregnancy outcome. The observation group was divided into notch group and non-notch group according to whether there was early diastolic notch or not. Pregnancy outcome. Results Compared with the control group, the resistance index, pulsatility index and systolic-diastolic velocity ratio in the observation group were significantly higher than those in the control group [(0.59 ± 0.06) vs (0.51 ± 0.03), (0.95 ± 0.18) vs (0.72 ± 0.12) vs (2.47 ± 0.52) vs (2.01 ± 0.31)], the differences were statistically significant (P <0.05); the weight of newborns in observation group was significantly lower than that of control group, the preterm birth, cesarean section, fetal distress was significantly higher than the control group, the differences were statistically significant (P <0.05). In the observation group, the incidence of early diastolic notch was 45.00% (36/80). The weight of newborn in notch group was significantly lower than that of non-notch group. The incidence of preterm birth, amniotic fluid abnormality and fetal distress were Significantly higher than no notch group, the difference was statistically significant (P <0.05). Conclusion Detecting uterine arterial hemodynamics with Doppler ultrasound in gestational hypertension patients is helpful to predict adverse pregnancy outcomes and has high clinical value.
