The effect of lullaby on sleep patterns changes in premature neonates after endotracheal suctioning in neonatal intensive care unit

Ground and goal: On one hand, preterm infants need to be confined to bed . because of maintaining the vitality and continued evolution of body systems. On the other hand, various exposures to offensive procedures can cause a lot of stresses that contradict neuron-sensory evolution. Direct observation of preterm infants and recognizing its behaviors can help nurses to do evolutionary supportive care, so they can control preterm infants pain and stress; So, goal of this research is determining the effect of lullaby on sleep patterns changes in premature neonates after endotracheal suctioning. Methods: 25 confined to bed preterm infants were studied in NICU ward of Hazrat Zeinab (peace be upon her) hospital of Shiraz in 1395 in this clinical trial. Samples were selected by packing method accidentally and allocated to two groups of A,B. If preterm infant was in group A, at first received lullaby by headphone 10 minutes before and also 10 minutes after suction. Then a headphone without lullaby (silent) was put on head of preterm infants 24 hours later. If preterm infant was in group B, it will be reversed. At last, each infant was evaluated twice In both cases the physiological responses were recorded, thenCollected through the APIB tool. Physiological filmed responses were recorded by tool of APIB. Data were analyzed by use of software SPSS ,Mann- Whitney Test. Results: The results showed that there was not significant difference between mean sleep score 10 minutes before suction in lullaby and silence group) P=0/077), but the mean sleep score of 10 minutes after suctioning was significantly difference in the two groups.( P=0/004). Also, Comparison of the mean sleep score in the lullabies group before and after the suctiont and also in the silence group with a significant level of 0.001 Showed a significant difference. Conclusions: According to the findings of this study, lullaby is effective in improving sleep patterns of preterm infants following painful procedures. It is recommended that nurses use this method as an effective intervention to improve the sleep patterns of neonates admitted to the neonatal intensive care unit.
