title: Usefulness of a selective neutrophil elastase inhibitor (sivelestat) in septic ARDS patients after gastrointestinal surgery.
abstract: OBJECTIVE
  The usefulness of a neutrophil elastase inhibitor (sivelestat) was evaluated for treating septic acute respiratory distress syndrome (ARDS) after gastrointestinal surgery.
  
  
  METHODS
  The subjects were 36 patients with septic ARDS after gastrointestinal surgery. ARDS was defined as acute lung injury associated with systemic inflammatory response syndrome. Sivelestat was intravenously administered at a dose of 0.2 mg/kg/hr continuously for 3 days or more. The effectiveness of sivelestat was evaluated based on the lung injury score, P/F ratio, and ventilator free days (VFD).
  
  
  RESULTS
  Marked responses were observed in 12 patients (33.3%), responses in 17 (47.2%), and no response in 7 (19.4%). In the patients with marked responses or responses (responders), the P/F ratio was significantly improved on day 3 of drug administration and at the end of administration compared with the pre-administration ratio. Comparison between the responders and non-responders showed significant differences on day 3 and at the end of drug administration. VFD significantly differed between the responders (18.8 days) and the non-responders (11.0 days).
  
  
  CONCLUSIONS
  In conclusion, sivelestat may be effective against septic ARDS. The effectiveness of the drug could be determined based on improvement in oxygenation ability on day 3 of drug administration.
