%X BACKGROUND: Preterm newborns have higher thoracic compliance, providing less stability to the different forces of distortion imposed on the rib cage, leading to instability of the chest. Adequate body position may reduce this instability and facilitate respiratory work. OBJECTIVE: To assess the oxygen saturation response of preterm newborns receiving rib cage stabilization with an elastic band in two body positions. METHOD: A clinical, prospective, randomized crossover study was conducted, including sixteen newborns with a gestational age of 31 to 35 weeks (mean 32.8 weeks) at a tertiary care facility, who did not receive supplemental oxygen. The infants were placed in a sequence of prone and supine positions with and without chest stabilization with an elastic band. Respiratory rate, heart rate, and oxygen saturation were measured at 10-minute intervals, corresponding to 7 samplings of 60 minutes. Data collection was interrupted when oxygen saturation was less than 90%. RESULTS: The mean gestational age of the infants was 32.8¡À1.5 weeks and the mean birth weight was 1,789¡À255g. Better values for the variables studied were observed in the supine position with an elastic chest band compared to the supine position without the band. The positions using an elastic band resulted in lower mean respiratory rate and heart rate and higher oxygen saturation. CONCLUSION: The use of an elastic chest band improves respiratory indicators such as oxygen saturation. CONTEXTUALIZA  O: Os rec¨¦m-nascidos pr¨¦-termos possuem maior complac¨ºncia tor¨¢cica, oferecendo menor estabilidade ¨¤s diferentes for as de distor  o impostas ¨¤ parede tor¨¢cica, o que leva ¨¤ instabilidade da caixa tor¨¢cica. A posi  o corporal adequada pode diminuir essa instabilidade, facilitando o trabalho respirat¨®rio. OBJETIVO: Verificar a resposta da satura  o de oxig¨ºnio em rec¨¦m-nascido pr¨¦-termo com estabiliza  o do gradil costal com faixa el¨¢stica em dois posicionamentos corporais. M¨¦TODO: Estudo com delineamento de ensaio cl¨ªnico prospectivo, randomizado e tipo crossover. Foram avaliados 16 rec¨¦m-nascidos com idade gestacional de 31 a 35 semanas (m¨¦dia 32,8 semanas) e sem oxig¨ºnio suplementar, em institui  o de n¨ªvel terci¨¢rio. O grupo foi submetido ¨¤ sequ¨ºncia de dec¨²bitos posturais ventral e dorsal, alterando-os com e sem estabiliza  o do t¨®rax por meio da faixa el¨¢stica. Os indicadores biol¨®gicos colhidos foram frequ¨ºncia respirat¨®ria, frequ¨ºncia card¨ªaca e satura  o de oxig¨ºnio. Os dados foram coletados de 10 em 10 minutos, totalizando 60 minutos com sete coletas. O crit¨¦rio de interrup  o da col
