Percutaneous umbilical cord blood sampling is a newer, safer, and more convenient technique and can be performed in the second and third trimester of pregnancy by direct puncture of the umbilical vein near its placental insertion, using a needle guided by ultrasound. Between 2-4 ml of pure fetal blood were obtained from 10 pregnancies at between 19 and 39 weeks' gestation. This new procedure offers access to the fetal circulation for diagnosis and therapeutic purposes.
经皮脐血采样是一种更新、更安全且更便捷的技术，可在妊娠中期和晚期通过超声引导下的穿刺针直接穿刺脐静脉靠近胎盘附着处来进行。在19至39周妊娠的10例孕妇中获取了2至4毫升纯胎儿血液。这一新技术为诊断和治疗目的提供了进入胎儿循环的途径。
