目的:通过一例母子Rh(D)血型不合引起的新生儿溶血症的病因调查分析,探讨积极开展产前血型血清学检查的重要性。方法:各项试验均应用血型血清学方法。结果:此患儿的溶血症是由来自母体的Ig G类抗-D引起。结论:抗-D抗体为Ig G性质,能够通过胎盘引起新生儿溶血症。因此,在产前血型血清学检查中,应对所有的孕妇进行产前血型血清学检查,及时发现其他血型系统Ig G类不规则抗体,这对新生儿溶血病的预防、诊断、治疗等方面具有重要的意义。
OBJECTIVE: To investigate the etiology of neonatal hemolytic disease caused by maternal Rh (D) incompatibility and explore the importance of actively carrying out prenatal blood group serological tests. Methods: Blood tests were used in all the tests. Results: Hemolytic disease in this child is caused by Ig G anti-D from the mother. Conclusion: The anti-D antibody is of IgG properties and can cause neonatal hemolytic disease through the placenta. Therefore, in prenatal blood group serological examination, all pregnant women should be prenatal blood group serological examination, and timely detection of other blood group Ig G class irregular antibodies, which for neonatal hemolytic disease prevention, diagnosis, treatment, etc. have Significance.
