What this trial studies

This project aims to investigate the impact of sodium supplementation on the growth and health of preterm infants. Infants will be randomly assigned to receive either sodium supplementation based on a urine sodium concentration algorithm or standard care. The study will monitor nutritional intake and collect stool samples to analyze the intestinal microbiome at various stages. Health information will also be gathered from medical records to assess the overall outcomes of the intervention.

Who should consider this trial

Good fit: Ideal candidates are preterm infants weighing more than 500 grams and born between 25 to 30 weeks of gestation, who are less than 14 days old at the time of randomization.

Not a fit: Patients with major congenital anomalies or significant renal dysfunction may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved growth and health outcomes for preterm infants.

How similar studies have performed: Other studies have suggested that sodium supplementation can positively influence growth in preterm infants, indicating potential success for this approach.
