Effects of creating an artificial night on physiological changes, weight and feeding tolerance in preterm infants.
Introduction:Nowdays,with medical advances in intensive care increased chance of survival in premature infants.One of the major concerns exposure to high light levels in neonate & subsequent it is increase in metabolism rate.So,this study was conducted to determine the effect of creating an artificial night on physiological changes, weight and feeding tolerance in preterm infants.
Methods: This is a randomized clinical trial dual group study, 38 preterm infants (gestational age of 30-34weeks)due to prematurity hospitalized at Ghaem NICU,were evaluated within 10 days. Infants were divided into two groups of 1200-1700 and 1701-2200g based on the weight and the weight of each group were randomized into artificial night(dark period was from 19 to 7 during incubator was covered with linen cloth & light period was from 7 to 19 removed the cover) and control groups(continuous lighting). Mothers & infants through questionnaires,interviews,observation & document completion, changes in physiologic & weight befor entering the study & then physiologic changes twice a day,weight & feeding tolerance were collected daily.Data were analyzed using spss v.16 software.

| artificial night | Other | Infants in the intervention group received light cyclic with pattern 12 hours. Light period was from 7 to 19 during which the infants were put in the normal environmental light and dark period was from 19 to 7 during which was the infants' incubator was covered with linen cloth. The vital signsand & arterial oxygen saturation of the infants in the intervention group were controlled before covering the incubator i.e. at 19. Also, the infant's vital signs were again monitored at 7 am.The infant weighed in every day at 7 am during the 10 days of study. Feeding tolerance was daily determined at 8 am, using nasogastric tube or orogastric tube to control residue as well as to review the presence or absence of abdominal distention, vomiting. |
