目的探索硝普钠和速尿对急性左心衰患者微循环的影响。方法将６０例急性心肌梗塞左心衰患者随机平均分成两组，一组静滴硝普钠，另一组静注速尿。通过微循环显微电视系统观测甲襞微循环多项指标变化。结果硝普钠组血流状态改善、微血管襻数目增加，红细胞聚集减轻。速尿组微血管襻数目减少，红细胞聚集加重。结论反复应用速尿，对心梗患者有诱发休克和再梗塞之弊。
Objective To explore the effects of sodium nitroprusside and furosemide on microcirculation in patients with acute left heart failure. Methods Sixty patients with left heart failure with acute myocardial infarction were randomly divided into two groups: one was intravenous sodium nitroprusside and the other was intravenous furosemide. Observing the changes of many indexes of microcirculation in microcirculation through microcirculation microscopic television system. Results The sodium nitroprusside group improved the blood flow state, the number of capillaries increased, and erythrocyte aggregation decreased. Furosemide group decreased the number of microvessel, erythrocyte aggregation increased. Conclusion Repeated application of furosemide, myocardial infarction in patients with induction of shock and re-infarction of the disadvantages.
