Micronutrient Monitoring and Management in Parenteral Nutrition-Dependent Premature Neonates: A Case Series

Area of Science:

• Neonatology
• Nutritional Science
• Pediatric Gastroenterology

Background:

• Prolonged parenteral nutrition (PN) is essential for premature neonates but carries risks.
• Micronutrient deficiencies, including vitamins A, E, and selenium, can occur in infants receiving PN.
• Gastrointestinal and liver complications are concerns in this vulnerable population.

Observation:

• A case series of 3 premature neonates on prolonged PN revealed abnormal vitamin A, E, and selenium levels.
• These infants experienced significant gastrointestinal issues such as intestinal perforation and necrotizing enterocolitis.
• All patients developed PN-associated liver disease, necessitating changes in lipid emulsion therapy.

Findings:

• Early identification and intervention for micronutrient abnormalities are critical.
• Supplementation and restriction strategies were employed to correct abnormal levels.
• Conflicting guidelines from major pediatric nutrition organizations (ESPEN and ASPEN) posed a treatment challenge.

Implications:

• There is a need for clearer, standardized guidelines on micronutrient monitoring and dosing in premature infants on PN.
• Further research is required to establish optimal management strategies for micronutrient imbalances in this population.
• Improved protocols could prevent severe complications and enhance outcomes for neonates requiring long-term PN.
