Effects of Mothers lullaby on physiological responses in Premature Infants Receiving Endotracheal Suctioning

Introduction: Endotracheal suctioning is one of common painful invasive procedures which are frequently performed on admitted babies is regarded as one of the most important caring challenges. This study aimed to determine the effect of lullabies with mother's voice on physiological responses followed by endotracheal suction in premature infants. Method: This study is  a clinical trial and it was done for five months on 40 preterm infants admitted in NICU in Afzalipour Hospital affiliated to Kerman University of Medical Sciences in 2016.After choosing the samples through continence sampling, infants were divided into two groups  of Routine care / Lullaby and Lullaby / Routine care. In the intervention time, mother’s lullaby was played for the infants five minutes before the suction and it continued until 10 minutes after the suction. The infants’ physiological responses (including the percent of arterial blood oxygen saturation, respiration and heart rate) were examined a minute before the suction of endotracheal systems as baseline data and after the suction it was measured every five minutes to thirty minutes. The statistical analysis was performed by using SPSS 23.   Results: The results showed that a mother's lullaby in intubated preterm infants who were suctioned, not only was effective on fast return of  breathing changes and heart rate after the suction, but also it reduced respiratory rate and heart rate. These changes showed no significant difference in the blood oxygen levels (spo2) of intubated babies who got oxygen through system. Conclusion: Mothers lullaby in taking care of preterm infants can a significant impact on their neonatal physiological responses.
