Prenatal care is that portion of obstetrics that has as its object the complete supervision of the pregnant woman to preserve the happiness, health, and life of both mo­ther and child. In a broader sense, prenatal care may include the entire development of a woman from her birth through the childbearing period. That is, the prevention of rickets in a child will give a woman with a nor­mal rather than an obliquely contracted pelvis; and the ear­ly removal of foci of infection will provide a better chance of a healthy potential mother. However, in a paper of this scope, we are forced to deal only with the management of the prospective mother from the time of conception to the deliv­ery of the child.
