近年来,由于国民经济和卫生服务事业的发展,特别是在计划生育优生优育工作中引入先进的科学技术后,围产期新生儿的畸形明显减少.畸形发生率及其种类也会发生相应变化,为了探索这一变化的规律,分析其变化的有关因素和趋势,我们对菏泽地区医院15年住院分娩的围产期新生儿39016例进行了调查研究. In recent years, due to the development of the national economy and health services, especially the introduction of advanced science and technology in the work of planning, childbirth, prenatal and postnatal care, the deformities of newborns in the perinatal period have been significantly reduced, and the incidence and types of deformities have also changed accordingly. In order to explore the law of this change and analyze the relevant factors and trends of its changes, we conducted a survey of 39,016 cases of neonatal perinatal neonatal births in 15 hospitals in Heze District Hospital.
