Leukoencephalopathy associated with extensive burns.

J B Gregorios

    Journal of Neurology, Neurosurgery, and Psychiatry
    |October 1, 1982
    PubMed
    Summary

    Extensive burns can cause unusual brain changes like demyelination and hemorrhages. A toxic metabolic state, possibly from burn toxins or bacterial action, is implicated in these severe neurological complications.

    Area of Science:

    • Neuropathology
    • Toxicology
    • Burn Medicine

    Background:

    • Extensive burns (second and third degree, >50% body surface area) can lead to severe systemic complications.
    • Neurological complications following severe burns are not well-characterized.
    • Metabolic acidosis, sepsis, and cardiorespiratory arrest are known complications of extensive burns.

    Observation:

    • Two patients with extensive burns exhibited unusual neuropathological findings.
    • Symmetrical perivascular demyelination predominantly affecting white matter was observed in both cases.
    • One patient also presented with petechial and ring hemorrhages, indicative of brain purpura.

    Findings:

    • The observed neuropathology included demyelination and hemorrhages in the brain.
    • Patients experienced metabolic acidosis, sepsis, disturbed consciousness, and cardiorespiratory arrest.
    • A toxic metabolic state, potentially involving burn toxins or bacterial byproducts, is suggested.

    Implications:

    • Severe burns can trigger unique neuropathological changes.
    • A toxic metabolic state and low platelet levels may be key factors in burn-related neurological dysfunction.
    • Understanding these mechanisms is crucial for managing critically ill burn patients.
