In this paper we will present the classification of the toxemias of pregnancy adopted by the American Committee on Maternal Welfare, consider briefly the pathogenesis of the acute and chronic diseases which are included in the hypertensive group of toxemias and review the results obtained by applying this concept of these toxemias and their classification in the management of parturition in our cases complicated by these diseases.
Lack of a uniform terminology for the toxemias of pregnancy influenced the American Committee on Maternal Welfare to appoint a subcommittee1 to classify these conditions and to define the terms used. At the outset this committee decided that a practical classification must be relatively brief and should contain sufficient descriptive terminology to permit the collection of data. The general term "toxemias of pregnancy" includes several complications of pregnancy; the majority of these have some clinical similarity, but some apparently are not related.
