摘　　要：为寻找一种方便可行的筛查方法，提高我国新生儿红细胞增多症（NP）的诊断率，对53例计划性剖宫广新生儿脐带血红细胞压积（UHCT）早期诊断NP的临床价值进行了观察与评估。结果：UHCT与出生2小时股静脉血红细胞压积（FHCT）相关良好，r＝0．624，P＜0．001；脐带血微量红细胞压积（UMHCT）与出生后FHCT相关不良。以UHCT≥0．58作为复查标准，111例新生儿中5例诊断为NP。5例中4例UHCT≥0.62。认为UHCT可作为筛查NP的首选方法，当UHCT≥0．62时高度怀疑NP，应复查FHCT。To find a easy and feasible method to increase diagnostic rate of neonatal polycythemia (NP), 53 subjects with hematocrit of umbilical cord blood (UHCT) and hematocrit of femoral vein blood (FHCT) were analysed. The results showed that the correlativity be tween UHCT and FHCT at two hours of life was good, r= 0. 629, p<0. 001. There were no significant correlation between microdose hematocrit of umbilical cord blood (MUHCT) and FHCT. 5 cases of NP were diagnosed within 111 subjects in follow-up examination with the standard of UHCT≥58% and 4 of 5 NP infants UHCT were ≥62%. It is suggested that UHCT is the initial method on NP screening. If UHCT≥62% NP is highly suspected and FHCT should be performed
