[Intra-alveolar hemorrhage. An uncommon accident in a breath holding diver].
To date, pulmonary oedema in breath hold divers has only been reported after dives below 50 meters, hypoxaemic syncope being the most common risk. We recently observed a 35-year-old well-trained breath hold diver who was unable to achieve deep inspiration during a high-level competition. After two hours of repeated dives to a depth of 25 meters for approximately 2-minute periods with intermittent recovery the patient developed cough and haemoptysis. The chest X-ray revealed lung images suggestive of intra-alveolar haemorrhage. The patient had taken 1 g of aspirin per os for three days prior to diving. Symptoms subsided spontaneously in 48 hours and one month later all haematology tests were normal except for minimal alteration of platelet aggregation. Pulmonary oedema in breath hold divers is usually attributed to blood shift to the pulmonary circulation related to the lowered intra-thoracic pressure. In our case, oedema was secondary to intra-alveolar haemorrhage favoured by aspirin which should be avoided before breath hold diving.
