虽然目前国内外一些研究者主张在心肺复苏时应用较大剂量的肾上腺素 ,认为能提高自主循环恢复率 ,但心肺复苏最终的存活率并未增加 ,甚至由于应用大剂量肾上腺素使机体α及 β肾上腺素能受体 (βＡＲ)过度兴奋 ,进一步加重复苏后的心肌损害 ,增加了自主循环恢复后的早期病死率 Although at home and abroad, some researchers advocate the use of larger doses of epinephrine in cardiopulmonary resuscitation, that can improve the recovery rate of spontaneous circulation, but the final survival rate of CPR did not increase, and even the use of high doses of epinephrine so that body α and β-adrenergic receptor (βAR) over-excitement further aggravates myocardial damage after resuscitation and increases early mortality after spontaneous circulation recovery
