各种原因之休克在病情严重和/或处置不当时,常并发急性肾功能衰竭,而不能保持机体内环境之平衡称休克肾,其病死率高达25～65％,现将需加注意的有关问题进行简要探讨。 一、休克对肾的影响 休克之本质是重要器官毛细血管灌流量的危急性锐减所引起的代谢障碍与细胞受损的病理过程,其主要病理环节是重要器官的微循环机能障碍。肾脏只有具备稳定的血液循环和正常的血液理化成分才能进行正常生理功能。正常成人两肾血流量相当于心输出量的20～25％,其中90～93％供应肾皮质,7～10％供应肾髓质,以保持滤过及浓缩功能
A variety of causes of shock in the serious condition and / or improper disposal, often complicated by acute renal failure, and can not maintain the balance of the body environment, said shock kidney, the mortality rate as high as 25 to 65%, it is necessary to pay attention to the relevant A brief discussion of the problem. First, the impact of shock on the kidney Shock is the essence of the important organ capillary perfusion acute crisis caused by metabolic disorders and cell damage pathological process, the main pathological link is the important organ microcirculation dysfunction. The kidneys only have stable blood circulation and normal blood physical and chemical composition in order to carry out normal physiological function. Normal adult renal blood flow equivalent to cardiac output of 20 to 25%, of which 90 to 93% supply of renal cortex, 7 to 10% supply of renal medulla in order to maintain filtration and concentration
