An organ protectant solution which is intravenously administered includes a high concentration of cell-impermeant molecules and at least one oncotic agent. The cell-impermeant molecules preferentially load into the interstitial space and the oncotic agent(s) is/are restricted to the vasculature space. Together, they promote transfer of water from cells to interstitium and into the capillaries, thereby preventing or reducing cell swelling, and maintaining blood circulation and oxygenation of tissues. The organ protectant solution extends the “Golden Hour” for traumatic and/or hemorrhagic shock patients, thereby allowing more time for those patients to reach a point of care facility to receive medical treatment.
