[Physiopathologic changes and morbidity in divers in saturation. Epidemiologic evaluation of 9 years' activities
Abstract:
An epidemiological study was made of 315 man-saturations over a period of 4508 days worked in saturation. The results were compared with those from 541 drillers working on a high-isolation site for periods of 30 days per shift making a total of 16,230 working days. Saturation was asymptomatic in 15,9%. The average length of conditions not interfering with diving or work was 3 days in the sample and 4 days in the controls. There were only two instances of type I decompression sickness in the divers (0,6%). These were both resolved without complications. Two subjects had to give up for health reasons (one case of parotitis and one anxiety-depression syndrome). It is felt that saturation is a very safe procedure as far as immediate pathological consequences are concerned, and that its minor pathological forms are of a significantly different type from those of the control series, especially with regard to ORL forms, upper airway conditions, sleep disturbances, and sensations of malaise and poor adaptation.
