Although prenatal genetic amniocentesis is an accepted procedure for certain high-risk pregnancies, there is no standard approach to prenatal counseling, timing of counseling, materials used and location of the procedure. This survey of 126 genetics centers offering prenatal genetic amniocentesis reviewed aspects of 48,502 counseling events and a total of 61,174 samples processed in 1982. Eighty-three percent of the samples were obtained after counseling at the centers. Of the patients counseled, 88.5% chose amniocentesis, but the utilization rates varied widely between the centers. The choice of amniocentesis varied measurably with the educational materials used but not with the center size. Educational materials, written or audiovisual, were used by genetics centers in counseling 82% of the patients. There was a wide variation in center size, counseling methods used, the timing and use of counseling, and patient responses in the survey population.
尽管产前基因羊膜穿刺术是某些高危妊娠可接受的操作，但对于产前咨询、咨询时间、使用的材料以及操作地点，尚无标准方法。这项对126个提供产前基因羊膜穿刺术的遗传学中心的调查，回顾了1982年48,502次咨询事件的各个方面以及总共处理的61,174个样本。83%的样本是在中心咨询后获取的。在接受咨询的患者中，88.5%选择了羊膜穿刺术，但各中心的利用率差异很大。羊膜穿刺术的选择因使用的教育材料不同而有显著差异，但与中心规模无关。遗传学中心在82%的患者咨询中使用了书面或视听教育材料。调查人群中的中心规模、使用的咨询方法、咨询时间和使用情况以及患者反应存在很大差异。
