近年产前胎儿诊断有长足进步,其一就是在许多医疗单位开展了经皮采取脐血检验(PUBS)。PUBS主要适应症是胎儿染色体异常的迅速诊断及胎儿溶血性疾病时检查胎儿状态,以及胎儿子宫内感染症(风疹、巨细胞病毒感染,弓浆体病、B_(19)病毒感染)的产前诊断或胎儿酸硷基平衡检查等。 PUBS确能给与最确实的胎儿信息,但是未能广泛开展的原因是:①手术技巧的困难可通过训练来解决;②医学法律问题。PUBS作为胎儿死亡原因有报告达1％,更有报告高达5％。与PUBS相关联的主要并发症是采血部位出血(30％)和胎儿心动过缓(5％),多为一时性,但有时也引起严
In recent years, there have been many advances in prenatal fetal diagnosis. One of them is the percutaneous cord blood test (PUBS) carried out in many medical units. The primary indications for PUBS are the rapid diagnosis of fetal chromosomal abnormalities and the examination of fetal status during fetal hemolytic disease and the prenatal period of fetal intrauterine infection (rubella, cytomegalovirus infection, bowel paste disease, B 19 virus infection) Diagnosis or fetal acid-base balance check. PUBS can really give the most accurate information on the fetus, but failed to carry out a wide range of reasons: ① the difficulty of surgical skills can be trained to solve; ② medical law issues. PUBS as a cause of fetal death have been reported up to 1%, more reports up to 5%. The main complications associated with PUBS are bleeding at the bleeding site (30%) and fetal bradycardia (5%), mostly temporary, but sometimes also causing serious
