Immediately following a burn injury, vasoactive substances are released from the injured tissues. These substances initiate changes in capillary integrity, allowing plasma to seep into surrounding tissues. Direct heat injury to vessels further increases capillary permeability, which permits sodium ions to enter the cell and potassium ions to exit. Overall, this creates an osmotic gradient, which leads to increases in intracellular and interstitial fluid volumes and further depletion of intravascular fluid volume.
