Which of the following causes can lead to excessive burn edema and shock in a patient with injuries totaling more than 50% -TBSA burn?
a. The heat from the burn leads to immediate vascular wall destruction and extravasation of intravascular fluid.
b. A positive interstitial hydrostatic pressure occurs in the dermis leading to burn wound edema.
c. Plasma colloid osmotic pressure is decreased because of protein leakage into the extravascular space.
d. Capillary permeability decreases in burned and unburned tissue, leading to hypovolemia.
C
Negative interstitial hydrostatic pressure represents an edema-generating mechanism and occurs for approximately 2 hours after injury. Additionally, plasma colloid osmotic pressure is decreased as a result of protein leakage into the extravascular space. Plasma is then further diluted with fluid resuscitation. Thus osmotic pressure is decreased and further fluid extravasation can occur.
