Older individuals exhibit altered metabolic responses to trauma, with increased blood glucose and cortisol levels. Understanding these age-related changes is crucial for developing effective treatments for elderly trauma patients.

Area of Science:

  • Trauma and metabolic response
  • Geriatric critical care
  • Endocrinology

Background:

  • Metabolic responses to trauma are well-documented in younger populations.
  • The influence of aging on these responses remains less understood.
  • Trauma significantly impacts glucose, insulin, and cortisol levels.

Purpose of the Study:

  • To investigate the effect of age on blood glucose, insulin, and cortisol responses after mild to moderate trauma.
  • To analyze how age influences metabolic adjustments during the "ebb" and "flow" phases of injury.
  • To correlate injury severity with hormonal and glucose levels in different age groups.

Main Methods:

  • Studied 33 trauma patients (ages 16-81) with Injury Severity Scores (ISS) from 5-38.
  • Measured serum glucose, insulin, and cortisol before resuscitation and 24-96 hours post-injury.

  • Assessed injury severity using Glasgow Coma Scale (GCS) and ISS.

    • Main Results:

    • Age correlated with increased serum glucose during both "ebb" and "flow" phases of injury response.
    • Serum glucose levels also increased with higher injury severity (lower GCS, higher ISS).
    • Older patients showed increased serum cortisol responses, which tended to decrease over time post-injury; serum insulin was not significantly affected by age.

    Conclusions:

    • Aging alters the metabolic and endocrine responses to trauma.
    • Elderly trauma patients exhibit distinct patterns of glucose and cortisol regulation.
    • Further research into age-specific trauma responses is essential for optimizing geriatric critical care and therapeutic strategies.
