α—激动剂甲氧胺在理论上对心脏骤停更有益,但这一点还未得到肯定的证实。α、β—激动剂肾上腺素仍是目前治疗心脏骤停的首选药物。晚近,动物实验和临床研究提示,目前推荐的肾上腺素剂量(1mg)可能太小,以致不能使每次骤停的心脏都能复跳,而应用大剂量肾上腺素(3～5mg)抢救心脏骤停可获成功。 The a-agonist, methoxyamine, is theoretically more beneficial for cardiac arrest, but it has not yet been confirmed. α, β-agonist epinephrine is still the drug of choice for the treatment of cardiac arrest. More recently, animal experiments and clinical studies suggest that the currently recommended dose of epinephrine (1 mg) may be so small that the cardiac arrest of each arrest can not be resumed, but the use of high-dose epinephrine (3 to 5 mg) Stop can be successful.
