What explains physiologically the edema formation that occurs with burns?
a. Vasoconstriction
b. Reduced capillary permeability
c. Increased capillary permeability
d. Diminished hydrostatic pressure within capillaries
ANS: C
With a major burn, capillary permeability increases, allowing plasma proteins, fluids, and electrolytes to be lost into the interstitial space, causing edema. Maximum edema in a small wound occurs about 8 to 12 hours after injury. In larger injuries, the maximum edema may not occur until 18 to 24 hours later. Vasodilation occurs, causing an increase in hydrostatic pressure.
