Several techniques for renal replacement therapy are now utilized to manage patients with acute kidney injury including intermittent haemodialysis, continuous renal replacement therapy, sustained low-efficiency dialysis, and peritoneal dialysis. This chapter provides an update on contemporary issues including advances in dialysis technology and its effects on the application of dialysis in acute kidney injury. The timing of initiation, modality choice, optimal dose, and management of complications in dialysis are some of the areas where there is controversy.

The Impact

Renal replacement therapy (RRT) can be used to support patient’s kidney function in cases of acute kidney injury (AKI). However, timing, modality, and dosing of RRT continue to remain in question. Recent studies have begun to provide data to help guide clinicians on when to initiate RRT, what form of RRT to use ranging from continuous venovenous hemofiltration (VVH) to intermittent hemodialysis, and the impact of high versus low-intensity dosing. Additionally, the risks associated with temporary vascular access with regard to thrombosis and infection, the impact of high efficiency and flux versus low efficiency and flux membranes, and options for anticoagulation in RRT for AKI are also discussed.

End Stage

Acute kidney injury (AKI) is a common syndrome encountered in critical illness and is associated with significant morbidity and increased mortality. Despite attempts to prevent the development of AKI, its incidence continues to rise, probably due to increased recognition in the setting of clearer definitions of the stages of AKI. Despite advances in the field of Nephrology, the treatment of AKI and its complications remains difficult in clinical practice. Critical care clinicians must have an understanding of the current definitions, pathophysiology, and treatment modalities. Renal replacement therapy (RRT) is a mainstay of treatment, but a lack of consensus regarding the optimal timing for initiation remains. There is a need for further research regarding both the timing of initiation of RRT and biomarkers that might allow earlier detection, differentiation of etiologies and monitoring of interventions.

Low Efficiency

Acute kidney injury (AKI) is a risk factor for increased mortality in critically ill patients. Sustained low efficiency dialysis (SLED) is a new approach in renal replacement therapy (RRT) and it combines the advantages of continuous renal replacement therapy (CRRT) and intermittent haemodialysis (HD). The study was aimed to evaluate the outcome of the hae-modynamically unstable patients with AKI in Bangladesh who were treated with SLED. So far this is the first reported study on SLED in intensive care unit (ICU) in Bangladesh. This quasi-experimental study was conducted in a 10-bed adult ICU of a tertiary care hospital in Bangladesh from June 2012 to May 2013. A total of 153 sessions of SLED were performed on 43 AKI patients. Mean age of the patients was 60.12 ± 15.57 years with male preponder-ance (67.4% were male). Mean APACHE II score was 26.88 ± 6.25. Fourteen patients (32.55%) had de novo AKI. Twenty nine patients (67.4%) had chronic kidney disease (CKD) with baseline mean serum creatinine 2.56 mg/dl, but did not require any RRT before admis-sion in ICU. After giving SLED, AKI of the study patients were completely resolved in 27.9%. Some forty two percent patients became dialysis dependant and 30.23% patients died. Patients who had AKI on CKD became dialysis dependant more often than the patients with de novo AKI (p <0.01). Mortality rate was significantly higher in patients who were on inotrope support (p= 0.017). Otherwise, there was no relation of 28 day mortality with age, prior renal function and mechanical ventilator requirement (p>0.05). Thus, SLED is an excellent renal replacement therapy for the haemodynamically unstable AKI patients of ICU. It is also cost-effective compared to CRRT.

Comparative Trials

Peritoneal dialysis, the first modality of renal replacement therapy used in patients with acute kidney injury, has now largely been supplanted by haemofiltration and haemodialysis. However, as acute kidney injury becomes more common and the need for renal replacement therapy increases, the technical advantages of peritoneal dialysis have made it an increasingly attractive option in acute settings, particularly in resource-deprived areas where haemodialysis is not available. Peritoneal modality can offer distinct advantages over haemodialytic techniques in patients with certain concomitant conditions. A variety of infectious, mechanical, pulmonary, and metabolic complications are possible with peritoneal dialysis, but the incidence of these is low in the acute setting. While not yet studied in robust comparative trials against the various haemodialytic modalities, there is some emerging evidence that peritoneal dialysis can provide adequate renal replacement therapy in acute settings, and acute peritoneal dialysis should be considered when haemodialysis is not available or its attendant complications are undesired.
