Evaluation of burn blister fluid.

J P Heggers, F Ko, M C Robson

    Plastic and Reconstructive Surgery
    |June 1, 1980
    PubMed
    Summary

    Burn edema does not impair nutrient diffusion, as blister fluid retains essential substances like penicillin. Cell membrane damage, indicated by enzyme levels, is likely due to cellular enzymes and complement activation.

    Area of Science:

    • Biochemistry
    • Cellular Biology
    • Burn Medicine

    Background:

    • Burn injuries cause immediate edema.
    • Understanding the biochemical changes in burn blisters is crucial for treatment.
    • Cellular integrity and nutrient transport mechanisms require investigation post-burn.

    Purpose of the Study:

    • To investigate the composition of burn blister fluid.
    • To determine if nutrient diffusion is impaired in the early stages of burns.
    • To identify the cellular and enzymatic factors contributing to burn pathophysiology.

    Main Methods:

    • Analysis of burn blister fluid composition.
    • Measurement of serum enzymes (SGOT, CPK, LDH).
    • Assessment of electrolyte balance and protein diffusion.

    Main Results:

    • Burn blister fluid composition resembles plasma/serum, containing various substances including penicillin.
    • Elevated potassium and cation-anion imbalance suggest Na/K pump malfunction.
    • Increased SGOT, CPK, and LDH indicate severe cellular trauma.
    • High-molecular-weight proteins (IgM, IgG) diffuse effectively into blister fluid.
    • Cell membrane permeability is compromised by complement and cellular enzymes like prostaglandins and thromboxanes.

    Conclusions:

    • Burn edema does not impede the diffusion of essential nutrients and administered drugs.
    • Cellular damage and altered membrane permeability are key features of early burn response.
    • Burn blister integrity is maintained despite significant cellular injury.
