Clinical Trial Summary

A single-center retrospective observational study comparing two cohorts of very low birth weight (VLBW, birth weight < 1500 grams) infants who received parenteral nutrition (PN) either before or after a concentrated PN regime was implemented into clinical use. Primary outcome is weight SDS at 28 days.

Description:

This study is a single-center retrospective observational study comparing two cohorts of very low birth weight (VLBW, birth weight < 1500 grams) infants who received parenteral nutrition (PN) either before or after a concentrated PN regime was implemented into clinical use. Both PN regimes were based on standardized PN solutions with the possibility to complement with additive nutritional products according to individual assessment by the attending physician. To meet recommended macronutrient intakes, in 2012 a concentrated parenteral nutrition regime was implemented into clinical use at the neonatal intensive care unit in Umeå University hospital, Sweden. However, there is a lack of data on how changes in nutrient intakes affect growth and electrolyte status in preterm infants. Recent studies have demonstrated an increased incidence of hypokalaemia, hypophosphatemia and hypercalcaemia in infants who received enhanced parenteral energy and protein intakes. This study is a single-center retrospective observational study comparing two cohorts of very low birth weight (VLBW, birth weight < 1500 grams) infants who received parenteral nutrition (PN) either before or after a concentrated PN regime was implemented into clinical use. Both PN regimes were based on standardized PN solutions with the possibility to complement with additive nutritional products according to individual assessment by the attending physician.

Eligibility

Inclusion Criteria:

• All infants VLBW infants admitted to the neonatal intensive care unit at Umeå University Hospital, Sweden, within 24 hours after birth and treated there for = 7 days, during 1 February 2010 and 30 September 2013.

The infants were divided into two groups:

1. infants born between 1 February 2010 and 18 February 2012, before the concentrated PN regime was implemented (Original PN group: n = 81), and

2. infants born between 19 February 2012 and 30 September 2013, after the concentrated PN regime was implemented (Concentrated PN group: n = 53).

Exclusion Criteria:

• Infants with chromosomal or severe congenital anomalies known to affect nutritional intakes and / or growth were excluded from the analyses.
