Mg. Rush et al., INTRAMUSCULAR VERSUS ENTERAL VITAMIN-A SUPPLEMENTATION IN VERY-LOW-BIRTH-WEIGHT NEONATES, The Journal of pediatrics, 125(3), 1994, pp. 458-462
We conducted a randomized trial in very low birth weight neonates (n =
51) to determine whether vitamin A supplementation by enteral adminis
tration would increase plasma vitamin A concentrations to the same deg
ree as by intramuscular administration. Mean plasma vitamin A concentr
ations were significantly higher in the intramuscular-administration g
roup than in the enteral-administration group by postnatal day 7; this
effect persisted throughout the remainder of the trial. At the dosage
used in this trial, vitamin A supplementation by the enteral route is
not as effective as that by the intramuscular route in very low birth
weight neonates.
