临床各科均可遇到急性肾功能衰竭,近代对其治疗已有一套较完整、成熟的疗法,但其死亡率仍很高,据报告各科综合死亡率约占50％左右,而创伤引起的急性肾衰死亡率达60—70％,诚然,降低急性肾功能衰竭的死亡率,是需要进一步探讨的问题。近年由于是微循环研究的深入,在死亡于急性肾衰的肾脏进行电子显微镜的观察,发现了肾脏的微循环内有凝血及 Acute renal failure can occur in all clinical departments. In modern times, a relatively complete set of mature therapies has been given to therapies, but the mortality rate is still very high. The comprehensive mortality rate of various departments is reported to account for about 50%, and trauma is caused Of acute renal failure mortality rate of 60-70%, of course, reduce the mortality rate of acute renal failure, is the need to further explore the issue. In recent years, due to the deepening of microcirculation research, electron microscopy was performed in the kidneys of patients with acute renal failure and found that there was coagulation in the microcirculation of the kidney and
