Newborn Health Problems & High-Risk Conditions | Chapter 8 – Wong’s Pediatric Nursing (11th)

Описание: This chapter provides a comprehensive examination of health problems affecting newborns, encompassing birth injuries, congenital abnormalities, and complications arising from high-risk physiologic states and maternal conditions. It details the pathophysiology and nursing management of birth trauma, distinguishing between soft tissue injuries like caput succedaneum, cephalhematoma, and subgaleal hemorrhage, as well as skeletal fractures and nerve palsies including facial paralysis and brachial plexus injuries. The text explores cranial deformities and structural defects such as cleft lip and cleft palate, emphasizing the multidisciplinary approach needed for surgical correction and specialized feeding techniques. A significant focus is placed on the high-risk newborn, categorized by gestational age and birth weight, including late preterm, very low birth weight, and extremely low birth weight infants. It analyzes the physiological immaturity of the preterm infant, specifically addressing respiratory distress syndrome caused by surfactant deficiency, and outlines therapeutic interventions such as mechanical ventilation, oxygen therapy, and exogenous surfactant administration. The chapter highlights critical components of neonatal intensive care, including thermoregulation, infection control, hydration, and nutritional support via gavage or breastfeeding, alongside developmental care strategies like kangaroo care to support neurodevelopment. Furthermore, it addresses severe complications such as necrotizing enterocolitis, retinopathy of prematurity, and bronchopulmonary dysplasia. The discussion covers hematologic disorders, explaining the mechanisms of hyperbilirubinemia, the risks of bilirubin encephalopathy and kernicterus, and the management of hemolytic diseases resulting from Rh alloimmunization or ABO incompatibility using phototherapy and exchange transfusions. Metabolic and endocrine dysfunctions are examined, particularly hypoglycemia in infants of diabetic mothers and congenital hypothyroidism. The text also details the clinical presentation and management of neonatal sepsis and infections within the TORCH complex. Additionally, it describes the impact of maternal substance use, outlining neonatal abstinence syndrome and fetal alcohol spectrum disorders. Finally, the chapter reviews inborn errors of metabolism, including phenylketonuria and galactosemia, stressing the importance of newborn screening and genetic counseling to prevent long-term cognitive impairment.
