Effects of cycled lighting on body weight, physiological variables and behavioral states in low birth weight infants

Abstract

PURPOSE: This study was aimed at finding the effects of cycled lighting on body weight, physiological variables and the behavioral state of LBWI (low birth weight infants) in the NICU. METHOD: The subjects were 20 LBWI at 2 NICUs. They were assigned to an experimental or control group which consisted of 10 subjects in each. Cycled light was applied to the experimental group for 10 days. RESULT: It was certified that the application of cycled lighting resulted in increased body weight and O(2) saturation, and decreased heart rate of the LBWI. However, there was no effect in decrease of respiration and stabilization of the behavioral state. CONCLUSION: The application of cycled lighting might be a nursing intervention which would in turn have positive effects on the growth of LBWI.
