Ultrasonically guided access to the fetal umbilical circulation offers an alternative to the standard management of the severe isoimmunized pregnancy. This technique allows fetal blood sampling, direct hematocrit analysis and intravascular transfusion. A severely Rh isoimmunized pregnancy is described in which five intrauterine transfusions of blood were given directly into the umbilical vein under ultrasound visualization. Technical aspects of the procedure and complications are discussed.
超声引导下进入胎儿脐循环为重度血型不合妊娠的标准处理提供了一种替代方法。该技术可进行胎儿血样采集、直接血细胞比容分析和血管内输血。本文描述了一例重度Rh血型不合妊娠，在超声直视下向脐静脉直接进行了五次宫内输血。文中讨论了该操作的技术要点及并发症。
