现已将胎儿做为患者予以诊断和治疗。例如在妊娠及分娩中利用胎儿监护以诊断胎儿窘迫,B型超声不但是对胎儿用视觉进行诊断,而且对其治疗亦创造了条件,与母血的生化检查相比可得到较多的情报。有关胎儿血流的测定虽然不能像成人那样直接测血压、心排出量和中心静脉压,但可通过胎儿各血管的血流波形而得到相应的血流情报。 The fetus has now been diagnosed and treated as a patient. For example, fetus monitoring is used to diagnose fetal distress in pregnancy and childbirth. Ultrasound B not only diagnoses the fetus with vision, but also creates conditions for its treatment. More information can be obtained compared with the biochemical examination of maternal blood. The measurement of fetal blood flow, although not as direct measurement of blood pressure, cardiac output and central venous pressure as adults, but through the fetus blood flow waveform and get the corresponding blood flow information.
