Chapter 13: Preterm & Postterm Newborns: Nursing Care

Preterm & Postterm Newborns: Nursing Care emphasizes that while birth weight was historically the primary focus, modern neonatal medicine prioritizes gestational age and the level of organ maturation to determine a high-risk status. For infants born before thirty-seven weeks, survival often depends on managing respiratory immaturity, particularly regarding respiratory distress syndrome (RDS) caused by a lack of surfactant, a fatty protein essential for lung expansion. Nursing interventions focus on stabilizing breathing, monitoring oxygen saturation with pulse oximetry, and implementing "cluster care" to allow for uninterrupted rest. A significant portion of care is dedicated to thermoregulation, as preterm infants lack the brown fat and muscle tone necessary to generate heat, making them highly susceptible to cold stress, which can lead to increased oxygen and glucose consumption. The chapter details common metabolic and physiological complications, including hypoglycemia, hypocalcemia, and an increased risk of intracranial hemorrhage due to fragile capillaries. Long-term risks such as retinopathy of prematurity (ROP), which can lead to blindness, and necrotizing enterocolitis (NEC), a serious inflammatory bowel condition, are also thoroughly discussed. In addition to preterm care, the chapter addresses the unique risks of postterm infants born beyond forty-two weeks, where the aging placenta may no longer provide adequate nutrition or oxygen, leading to fetal distress, meconium aspiration, and depleted glycogen stores. Assessment tools like the Ballard scoring system are used to determine physical and neurological maturity, allowing healthcare providers to tailor interventions. The nursing role extends beyond clinical monitoring to include the emotional support of the family, facilitating maternal-infant bonding through methods like kangaroo care (skin-to-skin contact) and teaching parents the specialized skills needed for gavage or parenteral feeding. Discharge planning is presented as a continuous process starting from birth, focusing on parental confidence, the "back-to-sleep" concept to prevent SIDS, and ensuring follow-up care for catch-up growth and developmental milestones. By integrating multidisciplinary support and advanced technology, nurses help manage the complex struggle for survival faced by high-risk neonates while preparing families for the transition from the neonatal intensive care unit to home life.
