Toronto: The survival rate of preemies -- premature babies -- born between 26 to 31 weeks of gestation can be improved by blocking light from reaching the intravenously-fed infused nutritious mixture they depend on for survival, says a new study.

Premature babies need to be fed intravenously due to the immaturity of their digestive system and their high nutritional requirements during their first days of life.

Exposing this type of food preparation to light generates oxidants which the premature infant's immature defences cannot fight."An easy to implement,

fully light-shielded delivery system for parenteral nutrition needs to be developed to reduce mortality rates in premature infants," said study's lead author Jean-Claude Lavoie from CHU Sainte-Justine, Canada.

Parenteral nutrition is essential to the survival of babies born preterm because it provides them with vital nutrients like proteins, fat and glucose, and enables them to develop just as foetuses of their age would do in their mother's womb.
