近十年来,急性肾功衰竭(ARF)发病机理的研究有了长足的进展,从而也出现了一些防治的新苗头。笔者复习了有关文献,旨在从ARF发病机理的新理论探索其防治新方法。肾缺血—多巴胺与速尿联用肾血流减少在ARF初期有重要的影响,常常是起动因素。及时恢复肾血流可预防ARF的发生。有人认为ARF时主要是髓质淤血,皮质 In the recent ten years, great progress has been made in the study of the pathogenesis of acute renal failure (ARF), thus some new signs of prevention and treatment have emerged. The author reviewed the literature, aimed at exploring the new prevention and treatment methods from the new theory of ARF pathogenesis. Renal ischemia - Dopamine and furosemide combined with renal blood flow reduction in the early ARF have a significant impact, often a starting factor. Timely recovery of renal blood flow can prevent the occurrence of ARF. Some people think that ARF is mainly medulla congestion, cortex
