Brief summary
The aim of this study was to assess the efficacy of the modified regimen short duration intrapleural 16mg alteplase (Actilyse, Boehringer Ingelheim) with 5mg DNase (Pulmozyme Hoffmann-La Roche Ltd) in patients with pleural infection.
Detailed description
The regimen 10 mg alteplase and 5 mg DNase twice daily that was used in MIST-2 trial is still an empiric choice. The rationale of using 3 doses of 16 mg alteplase dose (with supplementary 5 mg DNase) in our study was governed by the formulation of alteplase in our country (50 mg per ampoule); hence, it is best used within 24 hours following reconstitution as its biochemical stability up to 24 hours as assessed by in vitro clot lysis assays.
Interventions
