Cardiorespiratory effects of maternal sounds in infants born between 26 and 33 weeks of gestation. Rev. Enf. Ref. [online]. 2017, vol.serIV, n.12, pp.55-64.

Background: Care delivery to preterm infants is one of the health areas that have made most progress in recent decades, leading to more interventionist and innovative obstetrical and neonatal practices. Environmental and behavioral factors in neonatal intensive care units (NICUs) have been studied in order to analyze and identify their impact on PTIs. Objectives: To identify the effects of maternal sounds in the cardiorespiratory parameters of PTIs admitted to an NICU. Methodology: An experimental randomized study was conducted with 18 PTIs who were randomly distributed into 2 groups, in order to compare the effects of maternal sounds with the effects of the usual sounds at a NICU. Results: PTIs exposed to maternal sounds had a more stable heart rate (p = .000), higher respiratory rate (p = .000), and higher oxygen saturation (p = .000) than PTIs exposed to the usual sounds at a NICU. Conclusion: The results show the benefit of exposure to maternal sounds, leading to greater physiological and clinical stability of PTIs.
