新生儿不同日龄电子计数法血常规检查结果分析

ANALYSIS OF ROUTINE BLOOD COUNTS OF NORMAL NEWBORNS FOR DIFFERENTAGE GROUPS

鉴于近年来应用电子计数法，进行血常规检验日益增多，的确较准确、快速、实用。本文对１９９３年９月～１９９４年８月住院新生儿无明显因素影响血常规的前提下，对资料较完整的３７７例做了重点分析。结果表明，Ｒｂｃ、Ｈｂ、ＨＣＴ、ＭＣＶ、ＭＣＨ五项均在出生２４小进后，逐渐下降到晚期新生儿最低，按新生儿早、中、晚期比较，有统计学显著性差异，无性别差异、男女规律性近似；未成熟儿与足月儿则略有不同，前者略高于后者，随日龄增加其差别逐渐减小；ＭＣＨＣ变化不大。白细胞变化无新线索。血小板的变化与红细胞略有不同，血小板是随日龄增加而升高，到新生儿中期达高峰，以后逐渐稍降，但仍比早期新生儿为高；未成熟几例数偏少，尚待探讨。

Abstract:Application of using East-Asia F-800 automatic microblood cell count for 377 cases ofnormal newborns collected from september 1, 1993 to August 31, 1994. Altogether amongnormal full term newborns results show: 1. RBC, Hb,HCT,MCV and MCH all graduallylower down after 24 hours and to the normal lowest level at the end of newborn period. Ascomparison between early with middle and late age period of newborn, P values are <0. 05and <0. 01 respectively, but no statistic difference between male and female. As to plateletsit shows different pattern which is not known before. The highest peak at middle age groupand up to late age group it goes lower, but still higher than early age group. Nothing is sospeciallg new for Wbc.
