新生儿时期血象的变化波幅,是人一生中最明显的阶段,但有关大样本我国新生儿期血象的动态变化值的研究报道较少,为此,我们严选了广州和韶关两地区共450例汉族足月健康新生儿前瞻性测定了生后1～28天内共5次血象14项指标作动态观察及分析,旨在为临床和科研工作提供参考数据。现报告如下: The amplitude of blood changes during neonatal period is the most obvious stage in human life. However, there are few reports on the dynamic changes of neonatal blood counts in large samples. To this end, we have severely screened a total of 450 cases in Guangzhou and Shaoguan Cases of Han full-term healthy newborns were prospectively measured 14 indicators of blood 5 times within 1 ~ 28 days after birth for dynamic observation and analysis, aimed to provide reference data for clinical and research work. The report is as follows:
