肾脏不仅是排泄器官,而且具有调节内环境稳定的重要作用。新生儿期的肾功能与年长儿或成人相比,具有明显的年龄特点。对这些特点的了解有助于判断新生儿期的一些病理生理状态、指导保健及疾病防治措施的制定。早在1940年Barnett用菊糖廓清观察到小婴儿的肾小球滤过率(GFR)比年长儿低下,开拓了发育肾生理学的领域。但由于当时技术条件的限制而进展较慢。近十
The kidneys not only excrete organs, but also play an important role in regulating the stability of the internal environment. Neonatal kidney function compared with older children or adults, with significant age characteristics. Knowledge of these characteristics helps to determine some of the pathophysiological conditions in the neonatal period and to guide the development of health and disease prevention and treatment measures. As early as 1940, Barnett observed glomerular clearance in infants with glomerular filtration rate (GFR) lower than in older children, opening up the field of developing renal physiology. However, due to the technical conditions at the time the progress is slow. Near ten
