本文目的在于探讨弥漫性血管内凝血(DIC)对急性肾衰(ARF)预后的影响及肝素治疗之价值。在86例ARF患者中,属于产科21例,外科20例,外伤5例,内科37例,原因不明2例,心脏插管所致1例。DIC的诊断标准。血小板≤15×10~9/升,凝血酶原时间≥15秒,纤维蛋白原≤1.6克/升,并无肝脏病。伴有DIC的27例中12例用了肝素治疗,头24小时内的平均用量是每4小时用300毫克。肝素用量以凝血酶时间或凝血时间达到对照组的两倍为准。总的死亡率为55％。54例作了DIC检查,伴有DIC者比无DIC者的死亡率稍高,但差异不显著。肝素治疗组的死亡率(58％)并不比非肝素治疗组的 The purpose of this paper is to investigate the effect of diffuse intravascular coagulation (DIC) on the prognosis of acute renal failure (ARF) and the value of heparin therapy. Among 86 ARF patients, 21 were obstetric, 20 were surgical, 5 were trauma, 37 were internal medicine, 2 were unknown and 1 was cardiac catheterization. DIC diagnostic criteria. Platelets ≤ 15 × 10 ~ 9 / l, prothrombin time ≥ 15 seconds, fibrinogen ≤ 1.6 g / l, no liver disease. Twelve of 27 patients with DIC received heparin, with an average of 300 mg every 4 hours for the first 24 hours. The amount of heparin to thrombin time or clotting time reached twice the control group shall prevail. The overall death rate is 55%. 54 cases were examined by DIC, with DIC than those without DIC slightly higher mortality, but the difference was not significant. The mortality rate in the heparin group (58%) was not worse than in the non-heparin group
