title: [Usefulness of oxygen saturation in the assessment of children with moderated laryngitis].
abstract: OBJECTIVE
  The aim of this study was to determine the usefulness of oxygen saturation (SaO2) in the assessment of a child with moderate laryngitis (croup).
  
  
  METHODS
  A prospective study was carried out on 54 cases of moderate laryngitis (score of 2 to 6 of a possible 16) attended at our emergency department. Clinical score, heart rate, respiratory rate and SaO2 were recorded upon arrival. We analyzed the relationship between SaO2 and the requirement of nebulized epinephrine, parenteral dexamethasone and admission to the hospital.
  
  
  RESULTS
  Patients who received epinephrine showed SaO2 values lower than those who did not (96.8 +/- 1.9 vs 97.9 +/- 1.7), although this was not a significant difference (p = 0.11). Similar findings were seen when the requirement of parenteral dexamethasone was analyzed (96.7 +/- 1.9 vs 97.3 +/- 1.8, p = 0.28). Children admitted to the hospital showed SaO2 values significantly lower than those discharged (96.5 +/- 1.9 vs 97.6 +/- 1.7, p = 0.03). No differences were seen when heart rate or respiratory rate were analyzed.
  
  
  CONCLUSIONS
  We conclude that the measurement of is SaO2 useful in initial assessment of a child with acute laryngitis, essentially in order to better identify those patients who require admission to the hospital. It appears reasonable to include it in the initial assessment score.
