Pulmonary function and high-resolution computed tomography examinations among offshore drill floor workers

Area of Science:

• Occupational Health
• Pulmonary Medicine
• Environmental Health

Background:

• Offshore drill floor workers face exposure to airborne contaminants.
• Assessing the impact of this exposure on respiratory health is crucial.

Purpose of the Study:

• To evaluate short-term pulmonary function changes in currently exposed drill floor workers.
• To determine the prevalence of pulmonary fibrosis in previously exposed drill floor workers using HRCT scans.

Main Methods:

• A follow-up study measured pulmonary function in 65 drill floor workers and 65 referents before and after a 14-day work period.
• A cross-sectional study used HRCT scans to examine 57 previously exposed drill floor workers for pulmonary fibrosis.

Main Results:

• Drill floor workers showed a statistically significant decline in forced expiratory volume in 1 second (FEV1) over 14 days, unlike referents.
• Declines in FEV1 were associated with fewer days of active drilling.
• No signs of pulmonary fibrosis were detected in previously exposed workers.

Conclusions:

• A significant decline in FEV1 was observed in drill floor workers after 14 days offshore, potentially unrelated to oil mist.
• No pulmonary fibrosis was associated with oil mist exposure in the studied population.
