肾上腺素是目前治疗心脏骤停的首选药物,但肾上腺素治疗心脏骤停的最合理剂量目前尚未解决。美国心脏病学会推荐的肾上腺素剂量为每5分钟静注0.5～1.0mg,而晚近动物实验和临床研究则提示,此剂量可能太小,而应用大剂量肾上腺素抢救心脏骤停可增加心肺复苏成功率。最近,我们应用大剂量肾上腺素抢救3例心脏骤停患者,其疗效与文献报告一致。现报告如下。病例报告例1,患者女,74岁。因全身衰竭于1990年12月1日入院。1985年患冠心病心绞痛。临床诊断:癌症伴多脏器功能衰竭。12月17日6时28分患者出现呼 Adrenaline is currently the first choice for the treatment of cardiac arrest, but the most reasonable dose of epinephrine for cardiac arrest is currently unresolved. The recommended dosage of epinephrine for the American College of Cardiology is 0.5-1.0 mg intravenously every 5 minutes. However, recent animal experiments and clinical studies suggest that this dose may be too small, and the use of high-dose epinephrine to rescue cardiac arrest may increase cardiopulmonary resuscitation Success rate. Recently, we applied large doses of epinephrine to rescue 3 patients with cardiac arrest, the efficacy of which is consistent with the literature. The report is as follows. Case report 1, female patient, 74 years old. Due to systemic failure in December 1, 1990 admission. 1985 suffering from coronary heart disease angina. Clinical diagnosis: cancer with multiple organ failure. At 6:28 on December 17, patients appeared call
