In this online CME self-learning program:
When patients suffer an acute, intense inflammatory response, as in the cases of shock, sepsis, late hemorrhagic shock, and other circumstances, they have a high chance of incurring a permeability injury in their capillaries both systemically and in the lungs, which lends itself to the development of pulmonary edema. The risk of pulmonary edema may be heightened – or baseline pulmonary exacerbated – during the necessary course of fluid resuscitation, which may lead to extended courses of mechanical ventilation. It stands to reason, then, that if pulmonary edema is a concern during resuscitative and post-resuscitative care, that the medical team may curtail these risks by monitoring therapy via estimates of extravascular lung water (EVLW) – defined as fluid inside the lung tissue aside from that found in the vascular and pleural spaces.
In a hypotensive, hypoperfused patient, the benefit of giving a fluid challenge in determining next steps of care is in outlining the patient’s degree of cardiac stroke volume responsiveness. If it is, give fluid, and if not, then giving additional fluid, regardless of central venous pressure (CVP) – a popular measure that nonetheless does not predict fluid responsiveness. As fluid responsiveness begins to plateau, EVLW beings to steeply increase. A better approach may be monitoring estimates of EVLW. At the plateau of the Frank-Starling curve, EVLW begins to climb steeply. Thus, using an increase in EVLW as a threshold to stop volume resuscitation, marginal increases in cardiac output are sacrificed with the benefit of minimizing the risk of pulmonary edema. This program discusses an emerging, alternative guidance strategy.
