Epidemiological Assessment of Technical Diving Accidents in Mainland France and Factors Predictive of Severity (TEKCare)

Not yet recruiting

• Conditions: Decompression Sickness; Pulmonary Edema - Acute; Oxygen Toxicity; Carbon Dioxide Poisoning; Nitrogen Narcosis

• Registration Number: NCT06627153
• Lead Sponsor: University Hospital, Brest

Brief Summary

This retrospective study aims at an epidemiological description of the clinical presentation of medical problems in technical diving. It assess anthropometric data, diving experience and dive planification, clinical presentation, treatment received and pronostic to understand specificity of this community.

Detailed Description

In recent years, the increased availability of breathing gas mixtures, together with progressive technical development of specialized diving equipment, has contributed to expansion of the diver's community. Deep and long dives expose to decompression sickness (DCS) risk and hyperbaric oxygen therapy (HBO) is the definitive treatment. Incidence, clinical expression or prognosis of pathological events after technical diving might differ from recreational ones. A better knowledge of these specificity will facilitate risk assessment, analysis and medical care for hyperbaric physician community.

Primary Outcome Measures

Name	Time	Method
Demographic description of injured technical divers treated in French hyperbaric center	15 years	Comparison of technical diver populations according to length of hospitalization (\< 48 hours vs \> 48 hours) corresponding to treatment with simple hyperbaric oxygen therapy or requiring several consolidation sessions in view of the severity and/or intensity of symptoms.

Secondary Outcome Measures

Name	Time	Method
Predictive factor of severity	15 years	Evaluation regarding the number of OHB treatment (reflecting the gravity if more than 2) and diving profil (breathing apparatus, maximal depth, dive total time, composition of mixed gas), demographic profile of divers (age, sex, medical conditions) and symptoms presentation.
