title: [Sivelestat sodium for aspiration-related acute lung injury: a review and analysis of published case reports].
abstract: BACKGROUND
  There are conflicting views on the of sivelestat sodium (sivelestat-Na) on acute lung injury.
  
  
  METHODS
  The efficacy of sivelestat-Na on aspiration-related acute lung injury was analyzed by reviewing case reports published before or after the appearance of the drug on the clinical practice in Japan. Data were analyzed from the 23 sivelestat-treated cases and 5 non-sivelestat cases.
  
  
  RESULTS
  Sivelestat-Na was administered by 0.2 mg x kg(-1) x hr(-1) for 10 +/- 4 (mean +/- SD) days. PaO2/ ratio increased significantly from 124 +/- 59 mmHg of baseline to 253 +/- 79 mmHg on the third and to 361 +/- 84 mmHg on the termination of the therapy. Significantly better response was observed if the drug was administered within 24 hours after aspiration for patients with background of neurological disease, in which the increases in the P/F ratio were greater and the duration of the drug administration was shorter compared with other patients. In comparison with the non-sivelestat cases, sivelestat-Na therapy appears to be associated with shorter ventilator days or higher P/F increase, although sivelestat-Na costs higher.
  
  
  CONCLUSIONS
  These results suggest the possibility of conducting prospective clinical trials to assess the efficacy of early sivelestat-Na therapy for aspiration-related acute lung injury.
