Research progress of cardiac pre-load parameters in evaluating fluid responsiveness

Abstract

As the preferred treatment for most patients with hemodynamic instability in the intensive care unit(ICU), the fluid resuscitation can be limited by the cardiac function, that makes the fluid treatment has no responsiveness and may cause the risk of pulmonary edema increase.So, good fluid responsiveness is the basic condition to make fluid therapy successfully.For those patients, in order to lower the risk and correctly evaluate the fluid responsiveness, there are a large number of studies direct at the static and the dynamic pre-load parameters in animals and clinical patients.Those studies show that how to avoid the blindness of fluid expansion, accurately and effectively evaluate and forecast the fluid responsiveness.
