Many patients presenting to an intensive care facility will be pregnant. Many patients will have diseases peculiar to pregnancy and will need critical care support. Others, however, will have underlying medical diseases (Table 12.1). Some of those diseases will require consideration of the passenger (fetus) who has created many changes in maternal physiology. The hormonal milieu created by the placenta—progesterone and to a lesser extent estrogen—is responsible for the multifaceted changes in system function.
