Fluids and Electrolytes

Fluid and electrolyte derangements are commonly encountered in all pediatric settings; however, due to changes in body composition and electrolyte needs as the child grows from the neonatal period to adolescence, their management is often challenging. This chapter aims to summarize the information that the pediatrician needs to have in order to adequately address all fluid and electrolyte imbalances at any given age, as well as provide the necessary calculations to accomplish that goal.
