[Pulmonary edemas. Classification and mechanisms].

Water exchanges in the lung under physiological conditions, are still badly known. Starling's classical equation is a too simplified view of the phenomenon. In addition, a certain number of its factors are badly determined. Such is the case with the hydrostatic pressure and the oncotic pressure of the interstitium. In pathological conditions secondary edema is opposed to lesions of the alveolocapillary membrane and hemodynamic edema where the increase in intravascular pressure increases a loss of liquid between the junctions of the endothelial cells. Between these two situations there are edemas, of which the mechanism is still subject to discussion, for example altitude edema, edema in heroin addicts, neurogenic edema.

[Reduction and anti-inflammatory technics in non-hemodynamic pulmonary edemas].

All hypervolemia or any decrease in plasma oncotic pressure leads to deterioration in lesional pulmonary edema. The aim of albumin infusions is to restore the plasma oncotic pressure and to oppose the passage of water into the extravascular space. This therapy is however debatable owing to the abnormal increase in the permeability of the alveolo-capillary membrane to proteins. Diuretics enable one to lower the volemia and to maintain the pulmonary capillary pressure at its minimum level. However, strict hemodynamic supervision is absolutely necessary. Cortico-steroids have been recommended without serious physiopathological justification. However, they have a preventive action on interstitial edema in endotoxic shock.
