Respiratory functions in thermal burns.

F M Tripathi, K Pandey, P S Paul

    Burns, Including Thermal Injury
    |July 1, 1983
    PubMed
    Summary

    Burn trauma initially elevates respiratory rate and volume, with peak expiratory flow rate peaking around day 8. However, key lung function tests show no significant abnormalities in burn patients over three weeks.

    Area of Science:

    • Pulmonary Medicine
    • Trauma Care
    • Physiology

    Background:

    • Burn injuries significantly impact physiological functions.
    • Respiratory complications are a concern in burn patients.
    • Limited data exists on respiratory function changes in minor burns over extended periods.

    Purpose of the Study:

    • To investigate respiratory function changes in patients with minor burn injuries.
    • To monitor respiratory parameters for three weeks post-burn.
    • To assess the severity and duration of respiratory alterations after burn trauma.

    Main Methods:

    • Prospective observational study.
    • Inclusion of patients with minor burn extent.
    • Monitoring of respiratory rate, minute volume, tidal volume, and lung function tests (FVC, FEV1, FEV3, PEFR) over three weeks.

    Main Results:

    • Respiratory rate, minute volume, and tidal volume increased post-burn, peaking around day 8, then gradually decreased but remained elevated.
    • Peak expiratory flow rate showed a similar pattern, peaking on day 8.
    • Forced vital capacity and forced expiratory volumes (FEV1, FEV3) and their percentages did not show significant abnormalities.

    Conclusions:

    • Minor burn injuries cause transient, measurable changes in respiratory mechanics.
    • Despite initial alterations, major lung function parameters remain largely unaffected.
    • Further research may explore long-term respiratory implications in burn survivors.
