Consequences of U.S. Navy diving mishaps: decompression sickness.

A Hoiberg

    Undersea Biomedical Research
    |September 1, 1986
    PubMed
    Summary

    Navy divers experiencing decompression sickness (DCS) showed higher long-term hospitalization rates for vascular issues and symptoms like headaches. Most divers recovered fully, with few long-term disabilities or deaths reported.

    Area of Science:

    • Diving Medicine
    • Occupational Health
    • Vascular Health

    Background:

    • Decompression sickness (DCS) is a risk for divers.
    • Understanding long-term health effects is crucial for diver safety.
    • Previous research on long-term DCS outcomes is limited.

    Purpose of the Study:

    • To identify short- and long-term health effects in U.S. Navy divers after DCS.
    • To compare post-DCS hospitalization rates with a control group of divers.
    • To identify potential risk factors associated with DCS.

    Main Methods:

    • Retrospective cohort study of U.S. Navy divers (1968-1979).
    • Compared 328 divers with DCS to 1,086 matched controls without diving accidents.
    • Analyzed hospitalization records and physical disability separations.

    Main Results:

    • 76.5% of DCS divers had no subsequent diving-related medical events.
    • DCS divers had significantly higher rates of total hospitalizations, headaches, and arterial/venous diseases.
    • Conditions like joint pain, abnormal movements, limb pain, and arterial embolism were potential risks.
    • Divers with DCS were significantly heavier than controls.

    Conclusions:

    • While most divers recover from DCS, some experience increased long-term hospitalization for vascular conditions and symptoms.
    • Vascular diseases and specific neurological symptoms may indicate increased risk post-DCS.
    • Diver weight may be a factor in DCS outcomes.
