L'œdème aigu du poumon chez des patientes en menace d'accouchement prématuré traitées par inhibiteurs calciques : place de facteurs prédisposants ou pharmacologiques spécifiques ?

Calcium channel blockers of the dihydropyridin's family have been associated with the onset of an acute pulmonary edema when they are used as a treatment of preterm labor. We report here four cases of pulmonary edema in pregnant women treated with nicardipine (Loxen®) for preterm labor. The physiopathology of pulmonary edema, the pharmacology of calcium channel blockers of dihydropyridin's family and the detailed analysis of our cases and those of the literature make us discuss of the role of these agents and associated population and risk factors in such complication.
