心肺复苏与心脏前负荷——高质量心肺复苏的再思考

Preload in cardiopulmonary resuscitation-rethinking about high-quality CPR

心跳骤停是造成全球患者死亡的重要原因之一,虽然心肺复苏发病机制和救治措施的研究从未停止,但心肺复苏在过去的20年间其生存率未取得显著进展,全球的心肺复苏生存率仍仅有7%左右。过去的20年学者们充分认识到了按压质量在心肺复苏中的重要性。然而,心脏的前负荷对于心脏的射血非常重要,增加心脏前负荷能否增加心肺复苏时的心脏血流,仍然是我们需要进一步重视的问题。

Cardiac arrest is one of the leading causes of death all over the world.Despite the progress in the researches of pathopgenesis and management of cardiopulmonary resuscitation,the survival rate of patients with cardiac arrest has remained disappointingly low over the past two decades with only about 7%.On the other hand,in the past decades researchs about CPR mainly focus on the quality of compression.It is largely unknown the relation of preload and flow during cardiac resuscitation,evidence to augment preload during CPR may be one of futher direction to improve the outcome of cardiac arrest patients.
