[Does a preventive treatment of pregnancy toxemia exist: the role of aspirin].

After studying the risk factors of eclamptic toxemia, the author describes the various methods of prevention proposed. A salt-free diet has no effect. Increased intake of zinc or magnesium has no impact. Calcium (600 to 2,000 mg/d) may reduce the incidence of toxemia among teenagers from 27.9% to 4%. Low dose aspirin appears to be equally effective. Cod liver oil is currently being tested.
