Abstract
Anesthesia during pregnancy is challenging due to the extreme physiological
and anatomical changes that occur. Deep knowledge of these changes and how they
influence anesthesia is critical in order to offer safe anesthetic care to both, mother and
the child. In this chapter, we will review the main features that occur in the respiratory,
cardiovascular, central nervous, renal, and gastrointestinal systems, among others, and
how it affects pharmacodynamics, pharmacokinetics, airway management and conduct
of anesthesia. Fetomaternal circulation and fetal physiology focused on anesthesia will
also be discussed.
