Abstract

Introduction & Objective: Acceptance of newborns in the intensive care unit is regarded as one of the most important health care challenges due to the use of painful invasive procedures that are frequently performed on admitted infants. Today, the use of palliative non-pharmacological methods has been repeatedly emphasized in the literature. Therefore, the present study determine lullabies effect with mother's voice on heart rate in preterm infants during tracheal tube suction. Materials and Methods: This cross over-interventional study was conducted on 40 preterm infants during a five-month period in 2016, who were admitted in NICU in the Afzalipour Hospital affiliated to Kerman University of Medical Sciences. After convenience random sampling, infants were divided into two groups of Routine care / Lullaby and Lullaby / Routine care. At the intervention time, mother's lullaby was played for the infants from the 5 minutes before suction until 10 minutes later. Physiological responses of infants, including respiratory rate, were measured one minute before endotracheal suctioning as baseline information and five minutes to thirty minutes continued after suction. Finally, statistical analysis of data was performed by SPSS software version 23. Results: The results showed that mother's lullaby in intubated preterm infants who were suctioned, not only was effective on fast return of breathing changes after the suction, but also it reduced respiratory rate (0.007 p), which can also indicate the stress reduction in infants. Conclusion: The participation and presence of mothers in taking care of preterm infants not only improves the quality of nursing care, but can also has a significant effect on their physiological responses.
