Background and Aims: This randomized controlled study was conducted to investigate the effect of breast milk odor and white noise during heel lance on pain management in premature newborns.

Methods: The data were collected between 16th of May and 1th of October 2022 in Ankara University Hospital neonatal intensive care unit and postpartum services. The research included 66 newborns born between 34–37 gestational weeks in 3 groups (breast milk odor, white noise, control). Data were collected using Premature Infant Pain Profile-Revised Form, Descriptive Information Form and Follow-up Chart. The video recording started 5 minutes before and continued until 5 minutes after the procedure. Pain was evaluated 5 and 2 minutes before the procedure, at the time of the procedure and 5 minutes after the procedure by 2 independent academicians through recordings. Frequency, mean, standard deviation, chi-square test, one-way ANOVA, repeated measures ANOVA were used for data analysis.

Results: All three groups were similar in terms of descriptive information (p>0.05). Heart rate 5 minutes after the procedure was found to be lower in the breast milk odor and white noise group compared to the control group (p0.05). Oxygen saturation and pain scores were lower in the white noise and breast milk odor group compared to the control group in and after procedure times. It was observed that there was no difference between the breast milk odor and white noise groups at any time (p>0.05).

Conclusions: It is thought that both breast milk odor and white noise methods are effective in pain management in newborns.
