目的探讨多普勒超声在围生期孕妇中的应用。方法选取270例行多普勒超声检测的围生期孕妇为观察对象,比较并分析270例孕妇的多普勒超声检测结果和妊娠结果。结果 270例孕妇中,过期产孕妇2例,早产孕妇7例,其余孕妇为足孕产。经过多普勒超声得知正常孕妇的收缩期最大血流速度/舒张末期血流速度(S/D)、搏动指数(PI)、阻力指数(RI)都随着孕妇孕周的增加而减少。结论多普勒超声检测具有可反复使用,操作简单方便等优点,当孕妇足月妊娠S/D>2.5时,护理人员应该加强监视。
Objective To explore the application of Doppler ultrasound in pregnant women during perinatal period. Methods 270 perinatal pregnant women examined by Doppler ultrasonography were selected as the observation objects. The results of Doppler ultrasound examination and pregnancy of 270 pregnant women were compared and analyzed. Results Of the 270 pregnant women, 2 were women with obsolete births, 7 were premature births, and the remaining pregnant women were full-term pregnant women. After Doppler ultrasound, the maximum systolic blood flow / end-diastolic blood flow velocity (S / D), pulsatility index (PI) and resistance index (RI) of normal pregnant women decreased with the increase of gestational weeks. Conclusion Doppler ultrasound has the advantages of reusable, simple and convenient operation. Nursing staff should strengthen surveillance when pregnant women ’s term pregnancy S / D> 2.5.
