Hypophosphatemia in severe burns. A prospective study.

S Lennquist, B Lindell, H Nordström

    Acta Chirurgica Scandinavica
    |January 1, 1979
    PubMed
    Summary

    Severely burned patients often experience transient hypophosphatemia, a drop in serum phosphate levels, particularly between days two and ten post-injury. This condition, linked to phosphate depletion and elevated calcitonin, requires further investigation in burn care.

    Area of Science:

    • Biochemistry
    • Trauma Medicine
    • Endocrinology

    Background:

    • Severe burns can lead to significant metabolic disturbances.
    • Hypophosphatemia is a recognized complication in burn patients, impacting recovery.
    • The precise mechanisms and hormonal influences on post-burn hypophosphatemia require elucidation.

    Purpose of the Study:

    • To investigate the incidence and timing of hypophosphatemia in severely burned patients.
    • To explore the relationship between serum phosphate levels, urinary phosphate excretion, and mortality.
    • To examine the role of serum calcitonin and catecholamines in post-burn metabolic changes.

    Main Methods:

    • Prospective study of 33 severely burned patients followed for two weeks.
    • Combined data with a previous retrospective study for a total of 50 patients.
    • Monitored serum phosphate, urinary phosphate excretion, serum calcitonin, and catecholamines.

    Main Results:

    • Transient hypophosphatemia observed between days 2-10 post-burn in 33 patients.
    • Five of seven non-surviving patients exhibited critically low serum phosphate levels.
    • Reduced urinary phosphate excretion suggested prerenal phosphate depletion, though renal losses may also contribute.
    • A consistent, marked increase in serum calcitonin was noted.

    Conclusions:

    • Hypophosphatemia is a common, transient complication in severe burn injuries.
    • Low serum phosphate levels correlate with increased mortality in burn patients.
    • The interplay between elevated serum calcitonin, catecholamine secretion, and hypophosphatemia warrants further research for improved burn management.
