Abstract Aim The aim of this study was to evaluate the effect of maternal heart sound given to preterm infants during aspiration on pain and comfort. Methods This was a randomized controlled trial. Preterm infants ( n  = 62) receiving care or treatment at a neonatal intensive care unit (NICU) were eligible for participation in this study. Infants in the intervention group were provided with prerecorded maternal heart sounds before, during, and after aspiration, whereas infants in the control group received routine care. Results In both groups, the infants’ physiologic parameters were evaluated during aspiration. In the study, it was determined that while there was an insignificant difference between the experimental group and the control group in terms of respiratory rate and heart rate averages before, during, and after the aspiration, there was a significant difference between them in terms of SO 2 averages before, during, and after the aspiration, and this significance arose from the experimental group. Conclusion Considering the positive effect of maternal heart sound given to preterm infants during aspiration, we recommend that this method can be used in NICU.
