Doppler bloodflow velocity measurements in the umbilical arteries are quite generally used as a parameter for obstetrical management, notwithstanding the fact that restricted knowledge is available about the physiological and pathophysiological mechanisms of human umbilical circulation. The possible effects of maternal haemodynamic changes on the fetal circulation are only scarcely investigated. In a prospective study the effect of maternal exercise on the Pulsatility Index (PI) values measured in the umbilical artery with a pulsed Doppler device was assessed to investigate the need of standardization with respect to maternal exertion. The studied group consisted of 23 women with uncomplicated pregnancies of various gestational age, who underwent a moderate strain. Statistical analysis showed no significant difference in FHR and PI values before and after exercise, so it is concluded that it is not necessary to introduce a period of rest to precede a Doppler investigation.
尽管目前对于人类脐循环的生理和病理生理机制了解有限，但脐动脉血流速度的多普勒测量在产科管理中被广泛用作一个参数。关于母体血流动力学变化对胎儿循环可能产生的影响，目前研究甚少。在一项前瞻性研究中，评估了母体运动对使用脉冲多普勒设备测量的脐动脉搏动指数（PI）值的影响，以研究是否需要针对母体运动进行标准化。研究组由23名妊娠过程无并发症、处于不同孕周的女性组成，她们进行了适度的运动。统计分析表明，运动前后胎儿心率（FHR）和PI值无显著差异，因此得出结论，在进行多普勒检查之前无需安排休息时间。
