Neonatal Physiologic Characteristics 1. Total body water TBW varies inversely with fat content, and prematures have less fat deposits.

The Newborn's metabolic rate is high and extra energy is needed for maintenance of body temperature and growth. A change in body water occurs upon entrance of the fetus to his new extrauterine existence. There is a gradual decrease in body water and the extracellular fluid compartment with a concomitant increase in the intracellular fluid compartment.

This shift is interrupted with a premature birth. The newborn's body surface area is relatively much greater than the adults and heat loss is a major factor. Transepithelial skin water is the major component and decreases with increase in post-natal age.

Insensible water loss is affected by gestational age, body temperature radiant warmersand phototherapy. Neonatal renal function is generally adequate to meet the needs of the normal full-term infant but may be limited during periods of stress.

Renal characteristics of newborns are a low glomerular filtration rate and concentration ability limited urea in medullary interticium which makes them less tolerant to dehydration. The neonate is metabolically active and production of solute to excrete in the urine is high.

Fluid and Electrolytes Concepts Cellular energy mediated active transport of electrolytes along membranes is the most important mechanism of achieving and maintaining normal volume and composition of fluid compartments. Infants can retain sodium but cannot excrete excessive sodium. Electrolytes requirements of the full-term neonate are: As a rule of thumb, the daily fluid requirements can be approximated too: Special need of preterm babies fluid therapy are: They are susceptible to both sodium loss and sodium and volume overloading.

High intravenous therapy can lead to patent PDA, bronchopulmonary dysplasia, enterocolitis and intraventricular hemorrhage. Impaired ability to excrete a sodium load that can be amplify with surgical stress progressive renal retention of sodium.

Estimations of daily fluid requirements should take into consideration: Blood Volumes estimates of help during surgical blood loss are: The degree of dehydration can be measured by clinical parameters such as: Intravenous nutrition is one of the major advances in neonatal surgery and will be required when it is obvious that the period of starvation will go beyond five days.

Oral feeding is the best method and breast is best source. This is increased during stress, cold, infection, surgery and trauma. Variations in Individual Newborns 1. Types of Newborns Infants a The full-term, full-size infant with a gestational age of 38 weeks and a body weight greater than grams TAGA - they received adequate intrauterine nutrition, passed all fetal tasks and their physiologic functions are predictable.

The characteristic that most significantly affects the survival of the preterm infant is the immature state of the respiratory system. Between 27 and 28 weeks of gestation gramsanatomic lung development has progressed to the extent that extrauterine survival is possible.

It is only after 30 to 32 weeks of gestation that true alveoli are present. Once there is adequate lung tissue, the critical factor that decides extrauterine adaptation and survival of the preterm infant is his capabilities to produce the phospholipid-rich material, surfactant that lines the respiratory epithelium.Background.
