Evaluation of burn blister fluid

Abstract

Although edema is evident immediately after a burn, the diffusion of nutrient chemical constituents of the body is not impaired. Blister fluid, not unlike plasma or serum, contained all substances found in the body, including parenterally administered penicillin. The elevation of potassium and the cation to anion imbalance is primarily due to the Na/K cellular pump malfunction, and the destruction of the permeability of the cell membrane is most likely a direct result of complement and other cellular enzymes, which include the prostaglandins and thromboxanes. The elevated SGOT, CPK, and LDH indicated severe trauma to the cells in the immediate area of burn and possibly to the skeletal muscle. The presence of immunoglobulins indicated that high-molecular-weight proteins diffuse equally well during this edematous phase (IgM, 900,000; IgG, 190,000). Evidence of this nature strongly suggests that the integrity of the burn blister by maintained.
