随着卫生事业的发展,医疗水平不断提高,婴幼儿、新生儿发病率和病死率明显下降,而后期婴儿(出生后活过28天但未满1足岁)发病率及病死率下降速度相对比新生儿快,故新生儿发病率和病死率相对增加。因此降低新生儿发病率和病死率显得尤为重要,为此我们对1982年1月～1991年12月10年收治的864例新生儿住院病例做一回顾性分析。 With the development of health care and medical treatment, the morbidity and mortality of infants and newborns decreased significantly, while the incidence of infant and postnatal infants (28 days after birth but less than one full-year old) decreased at a relatively lower rate Faster than newborn, so the incidence of neonatal morbidity and mortality relative increase. Therefore, reducing neonatal morbidity and mortality is particularly important, for which we conducted a retrospective analysis of 864 neonatal inpatients admitted from January 1982 to December 1991.
