Admission blood glucose levels associated with NRDS severity in neonates

This was a retrospective cohort study of 219 neonates with neonatal respiratory distress syndrome (NRDS) at a tertiary hospital in China. The study categorized admission blood glucose levels into hypoglycemia, normoglycemia, and hyperglycemia, with the normoglycemia group serving as the comparator. The primary outcome was NRDS severity.

The main result showed that the incidence of severe NRDS was significantly higher in the hyperglycemia group (56.4%) compared to the normoglycemia group (38.7%), with a P value of 0.019. Secondary outcomes indicated that mechanical ventilation duration, oxygen therapy duration, and lactate levels were all prolonged or elevated in the hyperglycemia group, with all P values < 0.05.

Safety and tolerability data were not reported. Key limitations include the retrospective design and the single-center setting in China, which restrict generalizability. The study notes that the findings represent an association only; causality is not established.

In practice, these results suggest that admission glucose levels may be a marker for NRDS severity in this population, but they do not support causal interventions.
