急性肾衰竭患者病死率较高,而在临床工作中观察到非少尿型急性肾衰竭患者的预后好于少尿型肾衰竭。因此,有些医生使用大剂量的袢利尿剂试图将少尿型的肾衰竭转变为非少尿型的肾衰竭。但一些小型的随机对照研究评价速尿预防或治疗急性肾衰竭的作用均是阴性结果,而且肾功能不可恢 Patients with acute renal failure have a higher case fatality rate, and in clinical practice, patients with non-oliguric acute renal failure have a better prognosis than oliguric renal failure. As a result, some doctors use large doses of diuretics to try to convert oliguria-type renal failure into non-oliguric renal failure. However, some small randomized controlled trials evaluating the effects of furosemide on the prevention or treatment of acute renal failure are negative and have no recovery of renal function
