急性肾功能衰竭是由于双侧肾脏在短期内急剧削减了其排泄功能,而形成的临床综合征。由创伤所致的急性肾衰病死率为35～72%,术后发生者也高达35～70%。因此,如何预防急性肾衰的发生,已成为当前国际肾衰研究中重要方向之一。 Acute renal failure is a clinical syndrome that develops as the bilateral kidneys drastically cut their excretory function in the short term. The mortality rate of acute renal failure caused by trauma is 35 ~ 72%, and postoperative occurrence is as high as 35 ~ 70%. Therefore, how to prevent the occurrence of acute renal failure has become one of the most important directions in the current international study of renal failure.
