What is the primary reason for intravascular hypovolemia in the immediate period after a major thermal burn injury (>30% TBSA)?
Show answer and explanation
Correct answer: Capillary leak with plasma shifting into the interstitial space
Burn injury triggers increased capillary permeability and plasma leakage into interstitial space, causing intravascular volume loss and hemoconcentration.
