Summary
A health assessment of compressed air workers and divers revealed that most can continue hyperbaric work. However, 11.1% showed aseptic bone necrosis, a condition requiring careful monitoring and potential work restrictions.
Area of Science:
- Occupational Health
- Radiology
- Diving Medicine
Context:
- Compressed air work and diving involve significant hyperbaric exposure.
- Previous studies indicate potential risks of aseptic bone necrosis in these professions.
- A comprehensive health evaluation is crucial for worker safety.
Purpose:
- To assess the health status of compressed air workers and divers.
- To determine the incidence and severity of aseptic bone necrosis.
- To classify workers based on their suitability for hyperbaric environments.
Summary:
- A health check of 5,375 compressed air workers and divers was performed, classifying 4,859 individuals into four groups (A-D) based on work capacity under hyperbaric conditions.
- 84.4% (Class A) and 7.3% (Class B) were cleared for work, while 3.8% (Class C) and 1.8% (Class D) faced restrictions.
- Aseptic bone necrosis was diagnosed in 11.1% of individuals who underwent X-ray examination. Those in Class D often had co-existing hypertension, cardiovascular disease, or liver dysfunction.
Impact:
- Identifies a significant incidence of aseptic bone necrosis in compressed air workers and divers.
- Provides a classification system to guide work restrictions and prevent further injury.
- Highlights the importance of regular health monitoring for individuals in hyperbaric occupations.
