Rickets in a preterm infant during intravenous alimentation

Area of Science:

• Neonatal Medicine
• Pediatric Nutrition
• Biochemistry

Background:

• Preterm infants require specialized nutritional support.
• Intravenous feeding (parenteral nutrition) is crucial for non-enterally fed neonates.
• Rapid growth in infants necessitates adequate mineral intake.

Observation:

• A preterm infant receiving intravenous feeding developed severe rickets.
• Laboratory tests indicated hypophosphatemia as the primary cause.
• Clinical signs of rickets resolved with phosphorus supplementation.

Findings:

• Conventional intravenous infusates are phosphorus-deficient for preterm infants.
• Hypophosphatemia can manifest as severe rickets in neonates.
• Phosphorus supplementation is critical for preventing and treating rickets in this population.

Implications:

• Parenteral nutrition protocols need revision to include adequate phosphorus for preterm infants.
• Early monitoring for hypophosphatemia is essential in infants on long-term intravenous feeding.
• This case highlights the importance of tailored nutrient delivery for optimal infant growth and development.
