title: Response of oxygen saturation in preterm infants receiving rib cage stabilization with an elastic band in two body positions: a randomized clinical trial.
abstract: 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.
  
  
  METHODS
  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±1.5 weeks and the mean birth weight was 1,789±255 g. 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.
  
  
  CONCLUSIONS
  The use of an elastic chest band improves respiratory indicators such as oxygen saturation.
