Hypothesis
Will using rt-PA as a catheter locking solution decrease catheter malfunction compared to heparin?
Conclusion
The study aims to determine if weekly rt-PA reduces catheter malfunction compared to heparin.
Supporting Evidence
- Many hemodialysis catheters fail within one year due to thrombosis.
- The study will recruit patients from 14 sites across Canada.
- The primary outcome is catheter malfunction based on blood flow parameters.
Takeaway
This study is trying to find out if a special medicine called rt-PA can help keep dialysis catheters from getting blocked better than regular heparin.
Methodology
Randomized controlled trial comparing rt-PA and heparin as catheter locking solutions in hemodialysis patients.
Potential Biases
Potential bias in patient selection and treatment allocation despite blinding.
Limitations
The optimal dose and frequency of rt-PA administration are unknown, and previous studies have limitations in generalizability.
Participant Demographics
Patients requiring chronic hemodialysis with newly inserted permanent dual-lumen catheters.
