Cordocentesis was performed 96 times over a two-year interval, for a variety of diagnostic indications, in 55 completed pregnancies of 16-40 weeks' duration. There were four unsuccessful procedures, two associated with severe hydramnios and posterior placentas in which the available needles were too short. Sixty-three percent of procedures were successful on the first try; 95% succeeded within three attempts. Sixty-four percent of the samples were obtained from the placental cord origin, 27% from a free-floating loop, and 9% from the fetal cord origin. There were no maternal or significant fetal complications, and bleeding from the puncture site was not a problem. The present series confirms previous reports suggesting that in the proper hands, cordocentesis for diagnosis is a safe, rapid, and efficient means of obtaining access to the fetal circulation.
在两年的时间里，对55例孕周为16至40周的足月妊娠进行了96次脐带穿刺术，用于各种诊断指征。有4次操作失败，2次与严重羊水过多及胎盘位于后壁有关，当时可用的穿刺针太短。63%的操作首次尝试即成功；95%在三次尝试内成功。64%的样本取自胎盘脐带起始处，27%取自游离环，9%取自胎儿脐带起始处。未出现母体或严重的胎儿并发症，穿刺部位出血也不是问题。本系列研究证实了先前的报告，表明在技术熟练的人员操作下，用于诊断的脐带穿刺术是一种安全、快速且有效的获取胎儿循环通路的方法。
