title: [Comparison of oxygen saturation among newborns with bronchopulmonary dysplasia during and after feeding].
abstract: BACKGROUND
  Bronchopulmonary dysplasia (BPD) is associated with frequent events of hypoxemia specially during feeding.
  
  
  OBJECTIVE
  Determine peripheral oxygen saturation (SpO2) among infants with BPD before, during and after feeding.
  
  
  METHODS
  Patients with diagnosis of BPD were prospectively studied between July-September, 2005. SpO2 was measured with a manual digital pulsioxymeter 5 times during feeding. Alpha levels were set at p<0.05.
  
  
  RESULTS
  67 events were studied in 18 patients. For each participant, oxygen saturation was measured five times yielding a total of 335 recordings. Frequent desaturation episodes were recorded during feeding, (SpO2<88%) in 16 of the 18 cases. SpO2 reached 80% for some recordings among 67% of participants (n=12), with p<0.001.
  
  
  CONCLUSIONS
  Among BDP patients, SpO2 decreases during feeding, reaching severe desaturations (SpO2<80%) among in two thirds of the cases. Oxygen concentration must be sufficiently increased during feeding in order to rise the level of SpO2 to a minimum of 88%.
