Since the late 1970s, Doppler velocimetry has been investigated extensively for use in obstetrics. Initially, this technique showed promise for the management of certain complications of pregnancy; this promise has yet to be fulfilled. Doppler velocimetry of either the uterine or umbilical vessels, which showed some merit in selecting growth-retarded fetuses at particular risk, has neither become a screening tool for intrauterine growth retardation nor proven clinically successful in improving fetal outcome. Likewise, its use for other complications of pregnancy (eg, postdate pregnancy, twin pregnancy, and diabetes) has not led to improved pregnancy outcome. More recently this technique has been used to study other vascular beds. Changes in the Doppler characteristics of these vascular beds may demonstrate the fetal response to its environment. These investigations provide the potential for a better understanding of fetal physiology; however, it has yet to be shown by prospective evaluation that their application results in improved pregnancy outcome. This review defines the uses and limitations of Doppler ultrasound in current obstetric practice.
自20世纪70年代末以来，人们对多谱勒测速技术在产科中的应用进行了广泛研究。最初，这项技术在处理某些妊娠并发症方面显示出前景；但这一前景尚未实现。子宫或脐血管的多谱勒测速，在筛选特定风险的生长受限胎儿方面显示出一些优点，但既未成为宫内生长受限的筛查工具，也未在临床上证明能改善胎儿结局。同样，其用于妊娠的其他并发症（如过期妊娠、双胎妊娠和糖尿病）也未改善妊娠结局。最近，这项技术已用于研究其他血管床。这些血管床多谱勒特征的变化可能表明胎儿对其环境的反应。这些研究为更好地理解胎儿生理学提供了可能；然而，前瞻性评估尚未表明其应用能改善妊娠结局。本综述定义了多谱勒超声在当前产科实践中的用途和局限性。
