Summary
This study presents a citrate regional anticoagulation (CRA) protocol for continuous renal replacement therapy (CRRT) in patients with acute renal failure. The protocol uses readily available solutions, improving filter survival and clinical control.
Area of Science:
- Nephrology
- Intensive Care Medicine
- Critical Care
Background:
- Continuous renal replacement therapy (CRRT) is vital for acute renal failure management.
- Heparin anticoagulation is contraindicated in some CRRT patients.
- Extemporaneous preparation of anticoagulation solutions can be challenging.
Observation:
- A novel citrate regional anticoagulation (CRA) protocol was developed using only commercially available solutions.
- The protocol simplified measurement and control through five key dialysis-specific clinical parameters.
- Nursing staff demonstrated acceptance and ownership of the protocol.
Findings:
- The CRA protocol significantly improved dialysis filter survival in patients requiring CRRT.
- Excellent control of clinical and biochemical parameters was achieved.
- The protocol proved safe and effective for patients with contraindications to heparin.
Implications:
- This protocol provides a viable alternative for CRRT anticoagulation in resource-limited settings or those avoiding extemporaneous preparations.
- The findings support the widespread adoption of CRA using commercial solutions for CRRT.
- Further research may explore long-term outcomes and cost-effectiveness.
