Abstract

Patients who are victims of near drowning in fresh water or salt water very frequently have acute edema of the lung which occurs either immediately, or after a free interval of variable duration. The mechanism of this edema is explained, in near drowning in salt water, by the hyperosmolarity of the alveolar fluid leading to a seeping of plasma from the capillaries in the alveoli. In the case of near drowning in fresh water, it is on the contrary the inhaled liquid which passes into the circulation, therby leading to immediate hypervolemia, but this overload is only transitory and is not responsible for the pulmonary edema which occurs later is not accompanied by a rise in pulmonary capillary pressure. It is therefore a lesional edema as is certified by the anatomopathological modifications found in the lungs of drowned patients. Therapeutic management must therefore take into consideration this physiopathology of acute edema of the lung in the drowned.
