Complications of percutaneous umbilical blood samplings and intravascular transfusions can be detected rapidly, easily and efficiently by Doppler ultrasound and therefore the operator can react as early as possible. In addition to real-time sonography Doppler ultrasound allows for assessment of haemodynamical changes due to intravascular transfusions both on the venous and arterial side of umbilical perfusion. Because of immediate recognition of bradycardia and other fetal cardiac frequency alterations as well as increase of resistance to blood flow on the arterial side the operator can react promptly. On the venous side correct application of transfused volume is monitored continuously by changes of flow velocity waveforms during injection and allows to assess dislocation of the needle.
经皮脐血采样和血管内输血的并发症可通过多普勒超声快速、轻松且高效地检测出来，因此操作人员能够尽早做出反应。除实时超声检查外，多普勒超声还可评估脐部灌注静脉和动脉侧因血管内输血引起的血流动力学变化。由于能立即识别心动过缓和其他胎儿心率改变以及动脉侧血流阻力增加，操作人员可迅速做出反应。在静脉侧，通过注射期间流速波形的变化持续监测输注量的正确应用，并可评估针头移位情况。
