The Impact of Breast Milk Taste and Smell in Reducing Pain in Infants Undergoing Blood Drawing Procedure: A...

Infants hospitalized in neonatal intensive care units (NICUs) are exposed to numerous procedures that cause pain. In the literature, pain management methods in infants are evaluated by using breast milk in various ways. However, no study was found on whether the smell of breast milk, its taste, or both are more effective in pain management. The purpose of this study is to comparatively investigate the efficacy of breast milk taste and/or smell in reducing pain responses in infants undergoing a blood drawing procedure. The population of this study, which has a randomized controlled prospective design, consisted of infants who were treated in a NICU and met the inclusion criteria. The heart rate (HR), oxygen saturation (SpO₂), and pain of the infants were evaluated before, during, and after the blood drawing procedure in all groups. During and after the procedure, there were significant differences in terms of pain levels, SpO₂ levels, and HR between the groups (p = 0.000). The lowest pain score during the procedure was found in the infants to whom breast milk taste and smell were administered together. The group with the second-lowest pain score was exposed to the taste of breast milk. The group with the highest pain score was the control group. Breast milk smell and taste are recommended for use as a nursing intervention to reduce pain, decrease the HR, and increase SpO₂ in the NICU during painful procedures. Future research needs to explore different interventional practices.
