Multi-component lipid emulsion vs soy-based lipid emulsion for very low birth weight preterm neonates: A pre-post comparative study.

OBJECTIVE

To examine the effectiveness of soybean oil-medium chain triglycerides-olive oil-fish oil lipid emulsion (SMOF-LE) on clinical outcomes of very-low-birth-weight neonates.

STUDY DESIGN

We conducted a pre-post comparative study of very-low-birth-weight neonates, dividing them according to lipid emulsion received: Intralipid (soy-based; n = 680) or SMOF-LE (n = 617). Primary outcomes were mortality, chronic lung disease, severe retinopathy, infection, and necrotising enterocolitis. Secondary outcomes were cholestasis, osteopenia, time to full feeds, and time to regain birthweight.

RESULTS

Baseline characteristics between groups were comparable. Primary outcomes did not differ significantly between groups, although any retinopathy was significantly lower in the SMOF-LE group. SMOF-LE group had lower odds of cholestasis, osteopenia, and lipid interruption, and reduced times to full feeds and to regain birthweight.

CONCLUSIONS

Compared with Intralipid, SMOF-LE was not associated with differences in mortality and major morbidities but was associated with lower odds of any retinopathy, cholestasis, and osteopenia; and improved lipid tolerance.
