Combination Dornase and Alteplase for Intra-abdominal Drain, Abscess, and Hematoma Clearance: A Retrospective Case Series

All patients were discharged alive from the hospital. Clinical success was difficult to define due to variable goals of therapy. Further data are needed to establish the safety and efficacy of this practice, especially compared with intra-abdominal alteplase alone. Patients in our series generally received larger doses of alteplase than in prior studies due to use of dosing modeled on the MIST2 trial. Based on the limited experience of our study, we recommend holding therapeutic anticoagulation during the administration of intra-abdominal dornase-alteplase.
