Continuous renal replacement therapy

Continuous renal replacement therapy is a procedure in which patients with acute renal failure are dialysed slowly over 24 hours. The procedure is particularly well suited to intensive care settings where critically ill patients might be intolerant to traditional intermittent haemodialysis.

    Interest in the use of haemoperfusion for severe COVID-19 has been spurred by anecdotal reports of its efficacy and expert reviews suggesting theoretical benefits. However, on the basis of the limited current evidence, haemoperfusion remains an experimental therapy that should only be applied within the context of well-designed randomized trials.

    Continuous kidney replacement therapy (CKRT) can be a lifesaving intervention for critically ill patients; however, mortality remains high. The adaptation of existing innovations, including anti-clotting measures; cloud-computing for optimized treatment prescribing and therapy monitoring; and real-time sensing of blood and/or filter effluent composition to CKRT devices has the potential to enable personalized care and improve the safety and efficacy of this therapy.

    The need for innovation in dialysis is long overdue. As past and present users of dialysis we are fully aware of the limitations of current dialysis modalities. The time for complacency is over — developers must engage with dialysors to ensure that our needs are met so that we can live the best life possible. Let us share our dream for devices that will enable us to enjoy life.

    Haemodialysis is a life-saving therapy. However, in comparison with the healthy kidney, it removes only a small fraction of the uraemic toxins produced, does not function continuously and cannot replicate biological kidney functions. Innovations in membrane design hold promise to overcome these limitations with potential to improve patient outcomes.

    The prevalence of direct kidney involvement in novel coronavirus disease (COVID-19) is low, but such involvement is a marker of multiple organ dysfunction and severe disease. Here, we explore potential pathways of kidney damage and discuss the rationale for extracorporeal support with various blood purification strategies in patients who are critically ill with COVID-19.

    The IDEAL-ICU study reports no mortality benefit of early versus delayed initiation of renal replacement therapy (RRT) in patients with early septic shock and acute kidney injury. In the delayed initiation group, 17% of patients required emergency RRT but more than one-third spontaneously recovered renal function and did not require RRT.
