PY - 2016 T2 - Anesthesiology Core Review: Part Two Advanced Exam AB - The total body water of a newborn is 75%–80% and decreases gradually as fat and muscle content increase with age to the adult level of approximately 60%. The extracellular fluid (ECF) fluid represents 45% of body weight in term neonates and 30% by the age of 1 year, compared with 20% in adults. The term infant can compensate more than the preterm infant, but newborns with a large surface-to-weight ratio, higher total water content, limited renal ability to concentrate, greater insensible water loss from thin skin, and high blood flow can become clinically dehydrated in a very short period of time.
