对RHo(D)阴性妇女产后应用抗D丙种球蛋白预防是常用和有效的方法,然而作者仍然遇到由于严重的同种免疫引起的胎儿红细胞增多症的个别病例。近年来治疗上的进步已改善了受累妊娠胎儿存活的机会,但是一些致敏的妇女在妊娠时并不愿采用这些方法。人类Rh系统以Mendelian规律遗传,D或d占优势,所有欧洲人大约85%D是阳性,而且所有D阳性的个体中大约56%是杂合子(D/d)为对所有D阴性妇女和D阳性杂合子配偶的胎儿作出Rh-D抗原的早期及安全的产前诊断,对妊娠的进一步处理是最重要的。在妊娠早期末可能用绒毛标本(CVS)研究胎儿红细胞。与ABO抗原不
Postpartum use of anti-D-globulin prophylaxis in RHo (D) -negative women is a common and effective method, however the authors still encounter individual cases of fetal polycythemia due to severe alloimmunization. In recent years, advances in treatment have improved the chance of fetal survival in affected pregnancies, but some sensitized women are reluctant to use these methods during pregnancy. The human Rh system is inherited by the Mendelian law, with D or d predominance, with approximately 85% of all Europeans being D positive and about 56% of all D positive individuals being heterozygous (D / d) for all D-negative women and D An early and safe prenatal diagnosis of Rh-D antigen by the fetus of a positive heterozygous spouse is of paramount importance for further pregnancy. Fetal red blood cells may be studied by villus specimens (CVS) at the end of gestation. Not with ABO antigen
