目前国内外使用的早早孕终止方法颇多,如:各种抗早孕药物、催经止孕或吸经止孕术研究等。1972年Karmen 制成塑料吸管及吸简后,应用者渐多。国内大连计划生育研究所制成了CZ 型催经止孕器。国内外吸经对象多在6～7周或在5周以后,效果不够满意。国内外文献对停经36天内的早早孕进行诊断后行吸宫止孕术尚未见报道。我科于1980年初对停经36天内的对象应用放射免疫定量法测定血液hCG,计409例。自1982年初用改良极快速1(1/2)小时血hCG 放免定性法,计1000例。三年来共测停经26～36天之间的对象1409例。以血hCG>20ng/ml 为阳性,属妊娠。共作505例吸宫止孕术。经分析研究,探讨其安全性,证实是具有早、快、准的优点而受欢迎的一种止孕方法。
