Body temperature after accidental injury

R A Little, H B Stoner

    The British Journal of Surgery
    |April 1, 1981
    PubMed
    Summary

    Accidental injuries impact body temperature regulation. Severe injuries cause a drop in core and skin temperature, indicating impaired thermoregulation and reduced heat production.

    Area of Science:

    • Physiology
    • Trauma Medicine
    • Thermoregulation

    Background:

    • Thermoregulation is crucial for maintaining homeostasis.
    • Accidental injuries can significantly disrupt physiological processes.
    • Understanding post-injury thermoregulation is vital for patient outcomes.

    Purpose of the Study:

    • To investigate the effects of accidental injuries on core and skin body temperatures.
    • To correlate temperature changes with injury severity.
    • To explore potential mechanisms affecting thermoregulation post-injury.

    Main Methods:

    • Measured core and mean skin temperatures in 82 patients post-injury.
    • Assessed injury severity using the Injury Severity Score (ISS).
    • Analyzed the relationship between temperature and injury severity.

    Main Results:

    • Skin temperature decreased following injury.
    • Core temperature also fell, particularly in severe injuries.
    • Both core and mean body temperatures showed a negative correlation with the Injury Severity Score.
    • Reduced heat production due to impaired oxygen transport was implicated in core temperature drop.
    • Shivering, a expected thermoregulatory response, was absent in severely injured patients.

    Conclusions:

    • Accidental injuries, especially severe ones, impair thermoregulation.
    • Mechanisms include vasoconstriction and decreased heat production.
    • The absence of shivering suggests a significant disruption of thermoregulatory control.
