Abstract Introduction Animal studies of acute lung injury ALI suggest nebulised heparin may limit damage from fibrin deposition in the alveolar space and microcirculation. No human studies have been undertaken to date. We assessed the feasibility safety and potential anticoagulant effects of administration of nebulised heparin to patients with ALI. Methods An open label phase 1 trial of four escalating doses of nebulised heparin was performed. A total of 16 ventilated patients with ALI were studied. The first group was administered a total of 50 000 U day the second group 100 000 U day the third group 200 000 U day and the fourth group 400 000 U day. Assessments of lung function included the PaO2 FiO2 ratio lung compliance and the alveolar dead space fraction. Monitoring of anticoagulation included the activated partial thromboplastin time APTT and the thrombin clotting time. Bronchoalveolar lavage fluid was collected and the prothrombin fragment and tissue plasminogen activator levels were assessed. Analysis of .
