Carbon Dioxide Poisoning, Decompression Sickness, Nitrogen Narcosis, Oxygen Toxicity, Pulmonary Edema - Acute
Conditions
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.

Eligibility
Inclusion criteria
* Civilian technical diver * Diving accident history (decompression sickness, biochemical accident or immersion pulmonary edema) following a technical dive in a trimix and/or rebreather dive * Treated in a hyperbaric center on the coast of mainland France
Exclusion criteria
* Participation denied by the diver * Diving incident diagnosis not retained by the hyperbaric physician
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 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
| Measure | Time frame | Description |
|---|---|---|
| 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. |
