Objective: Since “Kangaroo Mother Care” (KMC) is among the common methods in Neonatal Intensive Care Unit (NICU) used to increase the weight of the children, this study aimed to evaluate the effect of music therapy (lullabies) on physiological and growth parameters in preterm infants during the “kangaroo mother care” (KMC).
Methods: This research was quasi-experimental study. The study population consisted of premature infants in Babol during the period March 2013 to February 2014. Because of difficulty in reaching preterm infants, samples were selected based on convenience sampling. The study sample consisted of 24 preterm neonates (12 infants in the experimental group and 12 infants in control group). First, pregnancy information questionnaire and then physiological parameters, including heart rate (in minutes) and arterial oxygen saturation were recorded daily. In addition, growth parameters including height and head circumference were weekly recorded in “Fenton's Growth Curve” and compared.
Results: Data analysis showed that the effect of treatment lullaby music on infants' weight gain was significant. In addition, the same efficacy was observed in the control group too. Regarding the effect of the intervention on infants' head circumference and height, it was observed that the intervention had a significant effect compared to the control group (p<0.001). The two groups were significantly different in terms of maximum heart rate (Ratemax), number of changes under the average (Changemin), number of changes above average (Changemax), minimum blood oxygen saturation (SPO2min) and the mean of blood oxygen saturation (SPO2mid) (p<0.05).
Conclusion: The results showed that kangaroo mother care (KMC) with music (lullabies) would lead to complementary environmental support besides medical support and play an effective role in improving infants' conditions and mothers' comfort.
