This chapter provides an overview of the background of fluid balance in the neonate, including the need to compensate for fluid loss (output), and the requirement to provide energy and nutrition. It also covers the management of common issues in fluid, electrolyte, and acid-base balance in the newborn period, including dehydration, sodium balance (hyponatraemia and hypernatraemia), hyperkalaemia, interpretation of blood gases (including pH, base excess, and anion gap), respiratory and metabolic acidosis, and hydrops fetalis.
