近来来临床和实验研究已证明硝酸甘油对急性心肌梗塞后左心衰竭有良好的血液动力学作用。然而,是否硝酸甘油对最严重的左室衰竭即严重肺水肿也有益处还未有系统研究。作者旨在证实单独硝酸甘油抢救严重肺水肿的疗效,将22例有肺水肿临床表现(端坐呼吸,紫钳,大汗和肺部罗音)患 Recent clinical and experimental studies have shown that nitroglycerin has a good hemodynamic effect on left heart failure after acute myocardial infarction. However, no systematic study has yet been conducted on whether nitroglycerin may also benefit the most severe left ventricular failure, severe pulmonary edema. The aim of the study was to confirm the efficacy of nitroglycerin alone in the management of severe pulmonary edema. Twenty-two patients with pulmonary edema (sitting-on-breath, red forceps, sweat and pulmonary rales)
