Pregnancy is associated with marked physiologic and anatomic changes in nearly every organ system of the body. Although these alterations are normal and necessary to meet the needs of the developing fetus and prepare the mother for parturition, their manifestations may resemble changes that in the nonpregnant woman would be indicative of pathologic states. Furthermore, the altered physiologic and anatomic relationships may change the pattern of injury or disease, and in many instances necessitate modifications in therapy. The purpose of this lecture is to review the anatomic and physiologic changes which the physician must understand to properly care for the traumatized pregnant woman. |
