Blocking light improves preemies' survival rates

The survival rate of preemies born between 26 to 31 weeks of gestation is improved by blocking light from reaching the intravenously-fed infused nutritious mixture they depend on for survival, researchers at CHU Sainte-Justine and the University of Montreal have revealed in 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. This also prevents serious potential complications such as pulmonary and kidney dysfunction or generalized infection. ?The conclusions to be drawn are clear. An easy to implement, fully light-shielded delivery system for parenteral nutrition needs to be developed to reduce mortality rates in premature infants?, said Jean-Claude Lavoie, lead author of the study which was published in the <I>Journal of Parenteral and Enteral Nutrition</I>.The survival rate of preemies born between 26 to 31 weeks of gestation is improved by blocking light from reaching the intravenously-fed infused nutritious mixture they depend on for survival,...
