During and after cardiopulmonary resuscitation, patients often have circulatory dysfunction and tissue hypoperfusion. Fluid management strategy has an important impact on hemodynamic stability and prognosis. Restrictive fluid therapy can reduce the risk of fluid overload and brain edema by accurately controlling the volume input. Although liberal fluid therapy strategy can rapidly restore blood volume, it may lead to poor prognosis. This paper summarizes the characteristics of the two strategies in volume management, reperfusion injury prevention and control, and neuroprotection, aiming to provide evidence-based reference for the development of a goal-oriented individualized fluid management program.
