Introduction: Previous studies have shown music therapy as a way to improve the clinical status of premature infants, improving vital signs and decreasing crying episodes. Objective: Compare the effects of music on vital signs of premature infants undergoing respiratory physiotherapy. Methods: We performed a randomized clinical trial consisting of 26 premature infants, divided into control group (N=12) and study group (N=14), carried out in a Neonatal Intensive Care Unit. All newborn infants undergone standard practice physiotherapy for 15 minutes: vibration and aspiration. On the study group they were exposed to classical music three minutes before the standard physiotherapy, and finished three minutes after the end of these procedures. A recorder was placed inside the incubator with an intensity of 25 decibels. Measurements of heart and respiratory rate and oxygen saturation were measured before, during and after each sessions of respiratory physiotherapy for two groups. Results: When comparing control and study groups regarding heart rate frequency and oxygen saturation, there was no statistically significant difference, but the inclusion of music determined clinically the variability of these data and 30% of the variation in respiratory rate was due to the inclusion of music during and after the physiotherapy, and the neonatal noninvasive ventilation showed less variation in their respiratory rate when compared to the neonatal on oxygen therapy. Conclusion: The results have showed a beneficial effect of music, showing lower respiratory rate in newborn infants during and after respiratory physiotherapy procedure.

Preterm newborns recognize facial stimuli and disclose no preference for natural faces, different from full-term newborns.

Objective: To evaluate thermal and cardiorespiratory adaptation during hot tub bath and shower in healthy newborns in the first hours of life. Study design: This is a randomized blind controlled trial, registered in ReBEC (No. RBR-4z26f3) with 184 newborns divided into hot tub group (n=84) and shower (n=100). Newborns from intervention group were immersed in a hot tub with warm water up to the neck, without exposure to air flow, and control group received traditional shower. Heart rate, respiratory rate and temperature were measured before and immediately after bath by an investigator blinded to the type of bath.Results: Groups were similar in gender, gestational age, birth weight, Apgar score at 5 th minute and hours of life, p => 0.05. To analyze thermal and cardiorespiratory adjustments, difference between postbath variables and pre-bath was calculated. In this analysis, it was found statistically significant difference between two types of bath regarding heart rate, respiratory rate and temperature. Hot tub bath decreases heart and respiratory rates and increases temperature, whereas shower provides the opposite effect (0.0001). Conclusion:This study demonstrates that hot tub baths and shower, in healthy newborns, promote thermal and cardiorespiratory adaptations, reflecting thermal, cardiac and respiratory positive reactions after hot tub bath.

Introdução: Considerando a alta complacência da caixa torácica em recém-nascidos, as manobras de fisioterapia, quando aplicadas sobre o tórax, devem ser corretamente indicadas e avaliadas, por meio de instrumentos fidedignos e não invasivos, a fim de assegurar a sua eficácia e segurança. Objetivo: Avaliar a mobilidade toracoabdominal pela biofotogrametria (MT) em recém-nascidos após as manobras de vibrocompressão (VC) e Reequilíbrio Toracoabdominal (RTA). Métodos: A análise foi realizada em 40 recém-nascidos, com idade > 37 semanas, em posição supina, membros superiores em flexão, abdução e rotação externa e quadril flexionado. Cada recém-nascido realizou um tipo de manobra (VC ou RTA) e foi filmado por 60 segundos antes e após a terapia, por uma câmera digital perpendicular ao plano de movimento. A análise biofotogramétrica foi realizada pelo Software AutoCAD® e os resultados foram convertidos para unidades métricas (cm2). Resultados: A manobra de RTA aumentou a amplitude do movimento toracoabdominal e a VC diminuiu. A diferença média da mobilidade toracoabdominal, entre o antes e depois, para estas duas manobras, foi de +0,20 cm2 no RTA e –1,72 cm2 na VC, entretanto não apresentaram diferença estatisticamente significativa. Conclusão: As manobras de RTA e VC apresentaram resultados antônimos sobre a mobilidade toracoabdominal, entretanto esta diferença não foi estatisticamente significativa.
