近年来,由于快速转运及早期抢救复苏的成就,创伤后急性肾功能衰竭(ARF)发病率明显减少,但创伤后及手术后ARF死亡率仍高达65％,与60年代相比,变化不大。诊断 ARF在临床上出现少尿、体液过多,酸血症或明显尿毒症,均非肾功能障碍的特异性表现。肾前及肾后因素也可导致合并氮质血症的ARF,诊断需采用摈除法。与ARF比较,肾前肾后致肾功能减退是容易恢复的。区分ARF发生的可能原因,需要对肾功 In recent years, due to the rapid transit and early rescue and recovery achievements, the incidence of acute renal failure (ARF) after trauma was significantly reduced, but post-trauma and postoperative ARF mortality was as high as 65%, compared with the 60’s, little change . Diagnosis of ARF clinically oliguria, body fluid excess, acidosis or significant uremia, are not specific manifestations of renal dysfunction. Prerenal and postrenal factors can also result in ARF with azotemia, and debridement should be used for the diagnosis. Compared with ARF, renal dysfunction after renal anorexia is easy to recover. Differentiate the possible causes of ARF, the need for kidney function
