This, the fourth volume in its series, focuses on fluid balance and its regulation in the fetus and neonate. With a high water content and rapid fluid movements, the fetus and neonate are more susceptible to fluid imbalances than the adult. This volume explains how fluid balance is regulated, by swallowing and by renal and lymphatic function. It then goes on to look at disorders of fluid balance and their pathophysiologies. Finally, the clinical section of the book focuses on management and correction of fetal edema, obstructive uropathies, oligohydramnios, polyhydramnios, and postnatal fluid disorders. This authoritative new publication provides a broad review of fluid balance and renal function from a scientific and clinical perspective.
