现代心肺复苏技术在20世纪50年代末60年代初逐步形成,经过几十年的发展,医疗技术水平不断进步。虽然复苏成功率有了明显提高,但心搏骤停患者的存活率并没有显著提高。心搏骤停后患者心、脑、肺、肾等全身各脏器由于缺血缺氧导致不可逆损害,最终导致死亡。其中最严重的即大脑缺血缺氧性损伤〔1〕。复苏后心功能不全亦是心肺复苏患者恢复自主循环后的常见并发症,约有1/3的患者在心肺复苏自主循环恢复后最终死于心功能不全〔2〕。其表现为在复苏恢复自主循环初期,不稳定的血流动力学状态、心功能衰竭、休克和心律
Modern cardiopulmonary resuscitation techniques gradually formed in the late 1950s and the early 1960s. After decades of development, the level of medical technology has been continuously improved. Although the success rate of recovery has been significantly improved, but the survival rate of cardiac arrest patients did not significantly improved. After cardiac arrest patients with heart, brain, lung, kidney and other organs of the body due to ischemia and hypoxia lead to irreversible damage, eventually leading to death. The most serious of which is the cerebral ischemia and hypoxic damage 〔1〕. Cardiac insufficiency after resuscitation is also a common complication of cardiopulmonary resuscitation patients recover autonomic circulation, about 1/3 of patients eventually died of cardiac insufficiency after cardiopulmonary resuscitation spontaneous circulation 〔2〕. Its performance in the early recovery and recovery of spontaneous circulation, unstable hemodynamic status, heart failure, shock and heart rate
