<prompt> All are decreased in burns exceptImmunityIntravascular volumeCapillary permeabilityAll the above  <response>: Heat causes coagulation necrosis of skin and subcutaneous tissue Release of vasoactive peptides Altered capillary permeability increased Loss of fluid - Severe hypovolaemia Decreased cardiac - Decreased myocardial output function Decreased renal blood - Oliguria flow Renal failure Altered pulmonary resistance causing pulmonary oedema Infection Systemic inflammatory response syndrome SIRS Multiorgan dysfunction syndrome MODS. There is increased capillary permeability, decreased plasma oncotic pressure causing loss of protein and fluid from intravascular space. Vasoconstriction occurs due to raised capillary hydrostatic pressure leading into cellular aggregation Ref: SRB 5th edition
