Abstract
The importance of nutrition in managing critically ill infants with congenital heart disease (CHD) is foundational to optimizing short- and long-term health outcomes. Growth failure and malnutrition are common in infants with CHD. The etiology of growth failure in this population is often multifactorial and may be related to altered metabolic demands, compromised blood flow to the intestine leading to nutrient malabsorption, cellular hypoxia, inadequate energy intake, and poor oral-motor skills. A dearth of high-quality studies and gaps in previously published guidelines have led to wide variability in nutrition practices that are locally driven. This review provides recommendations from the nutrition subgroup of the Neonatal Cardiac Care Collaborative for best evidence-based practices in the provision of nutritional support in infants with CHD. The review of evidence and recommendations focused on 6 predefined areas of clinical care for a target population of infants <6 months with CHD admitted to the ICU or inpatient ward. These areas include energy needs, nutrient requirements, enteral nutrition, feeding practice, parenteral nutrition, and outcomes. Future progress will be directed at quality improvement efforts to optimize perioperative nutrition management with an increasing emphasis on individualized care based on nutritional status, cardiorespiratory physiology, state of illness, and other vulnerabilities.
