一、三联针肾上腺素+去甲肾上腺素+异丙肾上腺素长期以来是复苏时心内或静脉内注射的首选三联给药。由于此三种药均属拟交感神经药,药理作用重复,近年对联合应用的价值又提出了新的认识。三联针中去甲肾上腺素主要兴奋α—受体。该药①可引起广泛性出血性心肌炎和严重的瓣膜病;②广泛收缩外周血管,增加心脏的后负荷,对心脏恢复有效搏动不利,同时严重影响各器官血液供应,引起组 One, triple needle adrenaline + norepinephrine + isoproterenol has long been the preferred triple or triple intravenous injection of recovery. Because of these three drugs are sympathomimetic drugs, pharmacological effects of duplication, the value of the joint application in recent years put forward a new understanding. Triple needle norepinephrine is mainly excited α-receptor. The drug ① can cause extensive hemorrhagic myocarditis and severe valvular disease; ② extensive contraction of peripheral blood vessels, increased cardiac afterload, adverse cardiac recovery effective pulsation, while seriously affecting the blood supply to various organs, causing the group
