Brief Summary:
The purpose of this international multi-center double-blind randomized placebo-controlled trial is to determine the effect of nebulized heparin, compared to placebo, on the number of ventilator-free days at day 28, in burn patients with confirmed inhalation trauma requiring mechanical ventilation.

Arm Intervention/treatment
Experimental: unfractionated heparin
25.000 IU/5 ml, will be nebulized 4 hourly (i.e. 6 times daily)
Drug: unfractionated heparin
nebulized 6 times daily, daily dose 150.000 IU for the maximum duration of 14 days
Other Names:
  • unfractionated heparin sodium, EV Product Code: SUB02475MIG,
  • Marketing Authorisation number: RVG 01372
  • ATC codes: B01AB01

Placebo Comparator: placebo
Sterile sodium chloride (NaCl 0.9%, Pfizer), in 5 ml, will be nebulized every 4 hours (i.e. 6 times daily)
Drug: placebo
Placebo: Sterile saline nebulized 6 times daily for the maximum duration of 14 days
Other Name: sterile sodium chloride (NaCl 0.9%)

Primary Outcome Measures :
  1. Number of ventilator-free days at day 28 [ Time Frame: at day 28 ]
    The number of ventilator-free days is defined as the number of days a patient is breathing without assist of a ventilator during the first 28 days; thus, the patient must be free of mechanical ventilation for 24 hours to have one ventilator-free day; if after successful detubation the patient requires a reintubation due to a surgical procedure, this reintubation will not count as a ventilator day - however, the day(s) will be counted as ventilator day(s) if mechanical ventilation is prolonged after surgery due to respiratory insufficiency.

Secondary Outcome Measures :
  1. Clinical outcome parameters [ Time Frame: daily or at day 28 and day 90 ]
    Clinical outcome parameters will include but not be restricted to: (a) length of stay (ICU and hospital); (b) mortality (28- and 90 days); (c) mortality (ICU and hospital); (d) daily Lung Injury Score (LIS); (e) daily Oxygenation Index (OI) ; (f) daily Sequential Organ Failure Assessment (SOFA)-scores ; (g) cumulative dosages of sedatives; (h) incidence of Ventilator-associated Pneumonia (VAP); (i) total number of bronchoscopy-guided cleaning of the larger airway

  2. Laboratory outcome parameters [ Time Frame: Blood and lavage samples: on admission day and every other day for a maximum period of 14 days ]
    Levels of markers of coagulation and fibrinolysis in blood and lung lavage fluid, Levels of markers of inflammation in blood and lung lavage fluid, Biomarkers of lung injury in blood and lung lavage fluid

  3. Safety parameters [ Time Frame: daily, for a maximum period of 28 days ]
    Safety parameters will include but not be restricted to: Occurrence of serious bleedings, any other transfusion of blood products - red cells and/or platelets and/or plasma, Confirmed Heparin induced thrombocytopenia, prolonged activated partial thromboplastin time (aPTT > 150 seconds)
