Effect of recorded maternal voice, breast milk odor, and incubator cover on pain and comfort during peripheral cannulation in preterm infants.

PURPOSE: This study was conducted to assess the effect of recorded maternal voice, breast milk odor, and incubator cover on the pain and comfort of preterm infants during peripheral cannulation.

METHODS: This study was a randomized controlled trial. The sample of the study included 136 preterm infants who met the case selection criteria. The infants were randomly assigned to different groups.

DATA COLLECTION TOOL: In the study, a recorded maternal voice was played to the maternal voice group. The breast milk odor group was exposed to the odor of breast milk. The incubator cover group was covered by using an incubator cover before, during, and after the peripheral cannulation procedure on the infants in the experimental group.

RESULT: While no difference was observed between the groups before the peripheral cannulation procedure in terms of the total Premature Infant Pain Profile (PIPP) scores, a significant difference existed between the PIPP scores during and after the procedure. This difference was due to the incubator cover group.

CONCLUSION: Breast milk odor, recorded maternal voice, and incubator cover in preterm infants are recommended as simple, safe, and supportive stimuli that facilitate positive effects during painful procedures.
