Which physiologic change causes the edema formation that occurs with burns?
a. Vasoconstriction
b. Decreased capillary permeability
c. Increased capillary permeability
d. Decreased hydrostatic pressure within capillaries
ANS: C
With a major burn, an increase in capillary permeability occurs, allowing plasma proteins, fluids, and electrolytes to be lost. Maximal edema in a small wound occurs about 8 to 12 hours after injury. In larger injuries, the maximal edema may not occur until 18 to 24 hours after injury. Vasoconstriction, decreased capillary permeability, and decreased hydrostatic pressure within capillaries are not physiologic mechanisms for edema formation in burn patients.
