No one doubts that good nutrition is an important component of neonata
l intensive care, nor that this can only be accomplished by the use of
intravenous fat. With regard to the effects of nutrition on bronchopu
lmonary dysplasia, however, we are facing a dilemma. On the one hand t
here is the suggestion that inadequate nutrition increases the severit
y of bronchopulmonary dysplasia and on the other that the use of intra
venous fat predisposes to it. In an attempt to narrow the area of unce
rtainty we randomly allocated 129 infants of less than 1750 g birth we
ight to receive either early or late lipid containing parenteral nutri
tion. The median duration of ventilation support in the 'early' group
was 8.5 days and in the 'late' group eight days; this was not signific
antly different.
