The effect of white noise and classical music on pain and physiologic parameters in preterm infants during retinopathy of prematurity examinations: a randomized controlled trial

Abstract

This study was designed as a prospective, randomized controlled trial. A total of 90 preterm infants who underwent retinopathy of prematurity (ROP) examinations were categorized into three groups, a control group, a white noise group (WN), and a classical music group (CM), each comprising 30 preterm infants. The study data were obtained using an information form and the Premature Infant Pain Profile. During (WN: 9.70±3.02; CM: 11.2±2.28) and after the examination (WN: 3.60±2.11; CM: 3.77±1.83), the preterm infants in the WN and CM groups had lower mean pain scores and heart rates (181.17±15.76 and 3150.10±17.03 vs. 173.30±20.66 and 146.67±18.17, respectively; p<0.001) and higher mean oxygen saturation values (93.60±3.87 and 97.83±1.93 vs. 95.73±2.52 and 98.27±1.82, respectively; p<0.05) than those in the control group; the differences were statistically significant. The WN and CM listened to by the preterm infants during ROP examinations had positive effects on pain and heart rate and oxygen saturation values.
