An organ protectant solution which is intravenously administerable includes a high concentration of cell impermeant molecules which have a charge and/or molecular weight which permit passage across a capillary endothelium and into an interstitial space in said subject but which are too large and/or charged to cross a cell plasma membrane such that said one or more cell impermeant molecules preferentially load into an extracellular fluid compartment can be used to to allow for improved organ harvesting from DCD and brain death donors for transplantation purposes and also can be used extend the “Golden Hour” for traumatic and hemorrhagic shock patients thereby allowing more time for those patients to reach a point of care facility to receive medical treatment.
