    Major burn victims risk selenium depletion due to specialized nutrition. Even with recommended intake, burn patients show biochemical evidence of lower selenium levels and related enzyme activity.

    Area of Science:

    • Biochemistry
    • Nutritional Science
    • Clinical Medicine

    Background:

    • Major burns increase nutritional demands, often necessitating specialized feeding methods.
    • Total parenteral nutrition and tube feedings may provide insufficient selenium (Se).
    • Selenium depletion is a potential concern for burn patients' recovery and health.

    Purpose of the Study:

    • To compare selenium status between burn patients and healthy controls.
    • To investigate the impact of different nutritional routes on selenium levels in burn patients.

    Main Methods:

    • Compared plasma Se, erythrocyte Se, erythrocyte glutathione peroxidase, and 24-hr urine Se excretion.
    • Assessed Se intake in burn patients on different nutritional regimens (TPN, tube feeding, oral diet).

    Related Experiment Videos

  • Included 17 burn patients and 191 healthy control subjects.

    • Main Results:

    • Burn patients exhibited lower plasma Se, erythrocyte Se, and glutathione peroxidase levels.
    • 24-hour urine Se excretion was also lower in burn patients.
    • Se intake was comparable to controls only when burn patients consumed oral diets.

    Conclusions:

    • Burn patients demonstrate biochemical evidence of selenium depletion.
    • This depletion occurs despite selenium intake within the recommended range for healthy adults.
    • Further research is needed to evaluate selenium supplementation in TPN and tube feedings for burn patients.
