Definitions of Hemodynamic Instability Related to Renal Replacement Therapy in Critically Ill Patients: A Systematic Review Protocol.
Can J Kidney Health Dis
January 2025
Faculty of Medicine, University of Ottawa, ON, Canada.
Background: Hemodynamic instability related to renal replacement therapy (HIRRT) is a common complication affecting critically ill patients that require renal replacement therapy (RRT). There is currently no consensus regarding the definition of HIRRT in critically ill patients. In this context, the impacts of HIRRT on clinical outcomes such as mortality or renal recovery in critically ill patients are unclear.

: Vascular access complications, particularly high venous pressure, pose significant challenges for hemodialysis patients undergoing hemodialysis. Limited research has focused on identifying predictive factors for invasive treatment. This study aimed to identify patients who might benefit from frequent monitoring and conservative management based on duplex ultrasound (DUS) evaluation.

Cardio-renal syndrome (CRS) is a complex condition involving bidirectional dysfunction of the heart and kidneys, in which the failure of one organ exacerbates failure in the other. Traditional pharmacologic treatments are often insufficient to manage the hemodynamic and neurohormonal abnormalities underlying CRS, especially in cases resistant to standard therapies. Device-based therapies have emerged as a promising adjunct or alternative approach, offering targeted intervention to relieve congestion, improve renal perfusion, and modulate hemodynamics.

Introduction Hemodialysis (HD) therapy is a crucial treatment for patients with renal failure but can impact the hemodynamics of antithrombin (AT), a protein essential for regulating hemostasis and preventing thrombosis. Reduced AT activity can lead to thrombus formation at unusual sites and increase the risk of recurrent venous thromboembolism. The loss of AT during HD or hemodiafiltration (HDF) through leakage or adsorption onto dialysis membranes has not been fully investigated, and its effects on AT hemodynamics remain unclear.

Background: Renal functional reserve (RFR) measures the difference between the stimulated glomerular filtration rate (GFR) and the baseline GFR to detect early signs of renal functional decline. The protein load test (RFR-T) is the gold standard for RFR assessment but is a complicated procedure. Renal intraparenchymal resistance index (RRI) variation test (DRRI-T) is a non-invasive method to measure renal function reserve using ultrasound.
