Changes in thrombin clotting time with nebulised heparin dosage. Upper: Change in the thrombin clotting time (TCT) over time. The last dose of heparin was given at 36 hours for all groups except the 400,000 U/day group, in which it was administered at 42 hours (mean levels). Lower: TCT at baseline and following the final dose of nebulised heparin (P = 0.1, analysis of variance comparison by dose, mean and standard deviation).
