This study evaluated the impact of a lower maximum dose of soybean oil lipid emulsion on bilirubin neurotoxicity in extremely preterm infants (<27 weeks or ≤750 g) through a single-center randomized trial. The results indicated that the lower lipid dose did not significantly reduce brainstem auditory evoked response wave V latency, with adjusted latencies of 7.36 ms vs 7.22 ms between the higher and lower dose groups, respectively.
Key findings
- Unbound bilirubin levels were higher in the higher dose group, with 28.6% having levels ≥ 40 nM compared to 16.1% in the lower dose group.
- Mean daily lipid administration was 1.1 g/kg/day in the lower dose group versus 1.96 g/kg/day in the higher dose group.
- Adjusted wave V latency was 7.36 ms in the higher dose group compared to 7.22 ms in the lower dose group.
Why it matters
Understanding the effects of lipid emulsion dosing on bilirubin neurotoxicity is crucial for managing extremely preterm infants, as elevated bilirubin levels can lead to neurodevelopmental issues. This study informs clinicians about the safety and potential risks associated with lipid dosing.
