Self-reported headache during saturation diving

Englund, Martin LU and Risberg, Jan (2003) In Aviation, Space and Environmental Medicine 74(3). p.236-241
Abstract
INTRODUCTION: Some commercial divers have claimed that headache is a frequent symptom related to decompression following a saturation dive, but due to lack of systematic reporting there is limited knowledge of the incidence and clinical characteristics of such headaches. METHODS: During 2001, a questionnaire was distributed to divers participating in offshore saturation diving operations on the Norwegian continental shelf. Two major diving contractors participated. The survey allowed anonymous self-reporting of past and present problems with headache; pain intensity was indicated daily on a visual analog scale (VAS) from 0 to 10. Of 95 divers, 56 participated and 67 saturations were registered. RESULTS: The divers estimated a higher... (More)
INTRODUCTION: Some commercial divers have claimed that headache is a frequent symptom related to decompression following a saturation dive, but due to lack of systematic reporting there is limited knowledge of the incidence and clinical characteristics of such headaches. METHODS: During 2001, a questionnaire was distributed to divers participating in offshore saturation diving operations on the Norwegian continental shelf. Two major diving contractors participated. The survey allowed anonymous self-reporting of past and present problems with headache; pain intensity was indicated daily on a visual analog scale (VAS) from 0 to 10. Of 95 divers, 56 participated and 67 saturations were registered. RESULTS: The divers estimated a higher frequency of headaches in connection to saturation diving than in everyday life (p < 0.001). One third of the divers reported experiencing headache after they finished decompression. There was a significant increase in reports of headache on the last day of decompression (p = 0.03) and on the first day post-saturation (p < 0.001) compared with the start of decompression. Median headache duration was 6 h (range 1-84 h) and median pain score estimated on a VAS was 2.5 (range 0.1-7.8), equivalent to moderate intensity. CONCLUSIONS: Headache incidence is greater in divers during saturation diving than in everyday life. The increase is correlated to the last phase of decompression and the post-saturation period. No specific cause(s) of the headache could be identified, but we discuss possible explanations. (Less)
