Acute kidney injury in newborns and chronic kidney disease / 国际儿科学杂志

ABSTRACT

Once umbilical cord ligation,neonatal kidney will be responsible for maintaining the whole-body homeostasis and the excretory requirements of the newborn. Meanwhile,there is a significant physiologic changes that occurs during the transition from intrauterine to extrauterine life. Neonatal renal reserve is less than adults,for the structure and function of the kidney still undergo a maturation process. Under the normal condi-tion,the adaptive changes of the renal function,with neonatal growth and development,can keep a delicate bal-ance of the internal environment. If they are exposed to a variety of external stressors,their immature kidney is especially vulnerable,which will not only cause fluid,electrolyte and acid-base imbalances and the adverse prog-nosis,but effect kidney structure and function further mature and increase the long-term risk of chronic kidney disease as well.
