Sensibility after burn injury.

A Hermanson, C E Jonsson, U Lindblom

    Clinical Physiology (Oxford, England)
    |December 1, 1986
    PubMed
    Summary

    Sensory recovery after burns is incomplete. Superficial burns impair touch sensation, while deep burns cause significant, lasting deficits in touch, temperature, and pain thresholds, with no improvement after one month.

    Area of Science:

    • Dermatology
    • Neurosurgery
    • Rehabilitation Medicine

    Background:

    • Burn injuries significantly impact cutaneous sensation.
    • Understanding sensory recovery is crucial for effective burn management and rehabilitation.

    Purpose of the Study:

    • To evaluate sensory recovery thresholds (touch, temperature, pain, two-point discrimination) in patients with varying burn severities.
    • To compare sensory outcomes between spontaneously healed superficial burns and surgically treated deep dermal/subdermal burns.

    Main Methods:

    • Assessed sensory thresholds in 36 burn patients and 27 healthy controls.
    • Examined three injury groups: superficial dermal (spontaneous healing), deep dermal/subdermal (early/late excision and grafting).
    • Utilized uninjured contralateral areas as controls.

    Main Results:

    • Superficial burns showed normal sensory recovery except for touch.
    • Deep dermal/subdermal burns exhibited significantly elevated sensory thresholds with no recovery beyond one month.
    • Sensory recovery was better in upper than lower extremities and in deep dermal vs. subdermal burns.

    Conclusions:

    • Current treatments for deep dermal and subdermal burns do not restore complete cutaneous sensation.
    • Even superficial burns lead to incomplete recovery of touch sensibility, highlighting the long-term sensory impact of burn injuries.
