Abstract

Background: Prematurity is the main cause of death in infants under one year of age and is the main reason for neonatal intensive care unit (NICU) hospitalization. The stressful environment of NICU exposes preterm infants to inappropriate stimuli. This study aimed to determine and compare the mean heart rate and oxygen saturation of premature infants before and during a designed program in NICU.

Methods: In a clinical trial study (before-after intervention) on a single group, 31 hospitalized premature newborns in NICU of Al-Zahra Hospital in Isfahan were selected by simple continuous sampling method. Data were collected through interview, observation and checklist records. The data were analyzed using SPSS and descriptive and inferential statistics.

Results: Out of 31 premature infants in the study, 60% were boys and 35% were girls. The mean (standard deviation) of oxygen saturation before and during the designed program were 92.80 (2.54) and 94.22 (2.59) percent, respectively. The results of paired t test showed a significant difference between the means of oxygen saturation of the infants before and during the program (p = 0.048), but there was no significant difference between the mean of the infants' heart beat before and during the intervention.

Conclusions: The findings showed that applying daily silence periods can greatly help to increase oxygen saturation and can improve the growth of premature infants. Therefore, by providing more facilities in clinical environments of NICU, conducting programs to reduce light and noise in these wards would be possible.

Keywords: Programmed instruction; light; newborn; noise; prematurity; pulse oximetry.
