The Study

  1. Randomised, controlled trial of children with croup score of 2-7 (out of possible 17) seen in A&E department.
  2. Randomisation was concealed and children, parents and clinicians were blind to treatment.
  3. They performed an intention to treat analysis.
  4. Control group (N = 27; 27 analysed) : 4 ml nebulized normal saline.
  5. Experimental group (N = 27; 27 analysed) : 4 ml nebulized budesonide (2 mg).

The Evidence

Admission one week later
EER CER ARR (95% CI) NNT (95% CI)
1/27 = 0.4 7/27 = 0.26 0.22 (0.042 to 0.402) 5 (2 to 24)

Mean 2 point reduction in croup score in treatment group (p<0.05).

Comments

  1. The small number of patients studied produces wide confidence intervals.
  2. Watch for more recent studies on this topic.
