近年来一些学者提出肾上腺素标准剂量(即推荐剂量)小于心脏停跳时的治疗量,故提出大剂量的肾上腺素可兴奋α-肾上腺素受体,使主动脉舒张压迅速提高,而冠状动脉灌注压=主动脉舒张压-右房压。因此提高主动脉舒张压是心肺复苏的关键。本组25例患儿,标准剂量组15例,肾上腺素剂 In recent years, some scholars have suggested that the standard dose of epinephrine (ie, the recommended dose) is less than the treatment of cardiac arrest, it was proposed that large doses of epinephrine may be excited α-adrenergic receptors, the aortic diastolic pressure increased rapidly, while the coronary artery Perfusion pressure = aortic diastolic pressure - right atrial pressure. Therefore, to improve aortic diastolic pressure is the key to cardiopulmonary resuscitation. The group of 25 children, the standard dose group of 15 cases, adrenaline agent
