Summary
COVID-19 significantly increases extracorporeal coagulation risk during continuous renal replacement therapy (CRRT). Monitoring blood pressure and vascular access is crucial for managing hypercoagulable states in kidney failure patients undergoing CRRT.
Area of Science:
- Nephrology
- Critical Care Medicine
- Infectious Diseases
Background:
- Lifting of COVID-19 control policies led to increased demand for hemodialysis and CRRT.
- Patients undergoing CRRT experienced more frequent hypercoagulable blood states post-policy changes.
- Understanding COVID-19's impact on extracorporeal circuits is vital for patient safety.
Purpose of the Study:
- To investigate the effect of COVID-19 on extracorporeal coagulation during CRRT.
- To identify incidence and risk factors for extracorporeal coagulation in CRRT patients post-COVID-19 policy changes.
Main Methods:
- Retrospective analysis of CRRT records from December 5th, 2022, to February 4th, 2023.
- Evaluation of clinical parameters including venous pressure, transmembrane pressure, and vascular access type.
- Analysis of blood tests to assess coagulation index alterations.
Main Results:
- COVID-19 substantially increased the likelihood of extracorporeal coagulation during CRRT.
- Higher venous and transmembrane pressures correlated with increased coagulation severity.
- Non-tunnel vascular access and acute kidney injury were risk factors for severe coagulation.
Conclusions:
- COVID-19 poses a heightened risk of extracorporeal coagulation during CRRT.
- Anticoagulant strategies, including adjusted heparin dosage and regional citrate anticoagulation, are important.
- This research provides reference metrics for coagulation risk during future pandemics and informs clinical practice.

Continuous Renal Replacement Therapy, also known as CRRT, is a procedural treatment for acute kidney injury (AKI) that gradually removes uremic toxins and fluids while maintaining acid-base balance and stabilizing electrolytes. It is particularly useful for hemodynamically unstable patients. Unlike intermittent hemodialysis, which is faster, CRRT provides a gentler approach over 24 hours, closely mimicking the function of natural kidneys. However, CRRT is not ideal for patients with...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Preoperative ManagementThe primary goals of preoperative management in kidney transplantation are to optimize the patient’s metabolic state and prepare them for surgery through diet adjustments, necessary dialysis, and tailored medical treatment. This phase also involves comprehensive infection screening and patient education about the surgical procedure and postoperative care to improve outcomes and adherence.Medical ManagementA comprehensive evaluation is required for both the living...
