This guideline is written primarily for doctors and nurses working in dialysis units and related areas of medicine in the UK, and is an update of a previous version written in 2009. It aims to provide guidance on how to look after patients and how to run dialysis units, and provides standards which units should in general aim to achieve. We would not advise patients to interpret the guideline as a rulebook, but perhaps to answer the question: "what does good quality haemodialysis look like?"The guideline is split into sections: each begins with a few statements which are graded by strength (1 is a firm recommendation, 2 is more like a sensible suggestion), and the type of research available to back up the statement, ranging from A (good quality trials so we are pretty sure this is right) to D (more like the opinion of experts than known for sure)...

INTRODUCTION: Extracorporeal renal replacement therapy may be needed in those infants in whom peritoneal dialysis is not feasible or is ineffective. Prolonged daily hemodialysis (PDHD) remains the only available extracorporeal dialytic modality in children weighing less than 10 kg, in setups where continuous renal replacement therapy is unavailable and sustained low-efficiency dialysis is not feasible due to lack of dedicated HD machines capable of delivering very low dialysate flows...

BACKGROUND: Anticoagulation is a cornerstone in haemodialysis (HD) therapy to avoid clotting of blood when it comes into contact with the dialysis membrane. Although heparins are usually administered as anticoagulants, they are not always sufficient to maintain adequate HD. We investigated the additional effect of acetylsalicylic acid compared with standard anticoagulation on maintaining adequate flow properties during HD in vitro. METHODS: We collected blood from 42 healthy volunteers, between 18 and 60 years of age, into bags filled with 1, 1...

BACKGROUND: For patients unable to receive heparin anticoagulation during haemodialysis, saline flushes to reduce circuit clotting are often the norm. Regional citrate anticoagulation (RCA) although effective is not used by many centres including in Singapore. We wanted to demonstrate the superiority and safety of a simple regional citrate anticoagulation regime, compared to saline flushes, for heparin-free low flux haemodialysis. METHODS: This is a prospective, open label, cross over study on 25 sequential haemodialysis sessions for inpatients receiving heparin-free haemodialysis...

INTRODUCTION: Intensive care participants that need dialysis frequently suffer from increased risk of bleeding. Standard intermittent haemodialysis (SHD) includes anticoagulation to avoid clotting of the dialysis system. The aim of this study was to clarify which of four different low-dose anticoagulant modes was preferable in reducing the exposure to i.v. unfractionated heparin (heparin) and maintaining patency of the dialysis circuit. METHODS: Twenty-three patients on SHD were included to perform haemodialysis with four modes of low-dose anticoagulation...

Pediatric liver failure patients frequently develop multiple organ failure and require continuous renal replacement therapy (CRRT) as part of supportive therapy in the pediatric intensive care unit. While many centers employ no anticoagulation for fear of bleeding complications, balanced coagulation disturbance predisposes these patients to clotting as well as bleeding, making maintenance of longer circuit life to deliver adequate dialysis clearance challenging. Regional citrate anticoagulation (RCA) is an attractive option as it avoids systemic anticoagulation, but since citrate metabolism is impaired in liver failure, concerns about toxicity has limited its use...

Therapeutic plasma exchange (TPE) has long been utilized to manage a variety of immune-mediated diseases. The basic principle relies on removal of circulating pathogenic substances from the bloodstream. Methods of plasma separation include centrifuge (cTPE) and membrane (mTPE). Although mTPE has existed for a few decades, recent advances in developing highly permeable filters that are compatible with currently existing dialysis machines has opened a new frontier. Published data in the area of technical and clinical experience with mTPE is lacking...

COMMENT
Heleen M Oudemans-van Straaten, Marlies Ostermann
Citrate has been recommended as the first-line anticoagulant for continuous renal replacement therapy (CRRT) in critically ill patients. Compared with heparin, citrate anticoagulation is safer and more efficacious. Citrate inhibits the coagulation cascade by lowering the ionized calcium (iCa) concentration in the filter. Monitoring of systemic iCa concentrations is inherent to the protocol, and monitoring of postfilter iCa is recommended to adjust citrate flow and optimize anticoagulation. While systemic iCa targets are in the physiological range, postfilter iCa concentrations are targeted between 0...

BACKGROUND: Continuous renal replacement therapy (CRRT) is a standard therapy in critically ill patients suffering from acute kidney injury (AKI). Extracorporeal circulation and exposure to foreign surfaces during CRRT may induce disturbances in hemostasis, particularly in platelet function. The present study described the hemostatic changes associated with CRRT and aimed to identify the independent predictors of premature clotting of the circuit. METHODS: In a prospective cohort mono-center study, patients were assessed for eligibility if they were i) diagnosed with AKI and ii) assigned to receive CRRT for the first time...

Prolonged intermittent renal replacement therapy (PIRRT) has emerged as an alternative to continuous renal replacement therapy in the management of acute kidney injury (AKI) patients. This trial aimed to compare the dialysis complications occurring during different durations of PIRRT sessions in critically ill AKI patients. We included patients older than 18 years with AKI associated with sepsis admitted to the intensive care unit and using noradrenaline doses ranging from 0.3 to 0.7 µg/kg/min. Patients were divided into two groups randomly: in G1, 6-h sessions were performed, and in G2, 10-h sessions were performed...

BACKGROUND: Previous pharmacokinetic trials suggested that 40 mg subcutaneous enoxaparin once daily provided inadequate thromboprophylaxis for intensive care unit patients. Critically ill patients with acute kidney injury are at increased risk of venous thromboembolism and yet are often excluded from these trials. We hypothesized that for critically ill patients with acute kidney injury receiving continuous renal replacement therapy, a dose of 1 mg/kg enoxaparin subcutaneously once daily would improve thromboprophylaxis without increasing the risk of bleeding...

INTRODUCTION: Regional citrate anticoagulation (RCA) is used as an anticoagulant for continuous renal replacement therapy (CRRT). A systemic calcium (Ca2+) infusion is required to replace Ca2+ lost in the effluent. The shortage of intravenous Ca2+ in the United States has limited RCA use. We describe a continuous veno-venous hemofiltration (CVVH) protocol with RCA using 2.2% anticoagulant citrate dextrose formula-A (ACD-A) and a commercial dialysate containing Ca2+ 1.5 mmol/l (N × Stage) as post-filter replacement fluid (RF), without need for Ca2+ infusion...

Delivered dialysis dose by continuous renal replacement therapies (CRRT) depends on circuit efficacy, which is influenced in part by the anticoagulation strategy. We evaluated the association of anticoagulation strategy used on solute clearance efficacy, circuit longevity, bleeding complications, and mortality. We analyzed data from 1740 sessions 24 h in length among 244 critically ill patients, with at least 48 h on CRRT. Regional citrate, heparin, or saline flushes was variably used to prevent or attenuate filter clotting...

UNLABELLED: Intermittent hemodialysis (IHD) and continuous renal replacement therapies (CRRT) are used as Acute Kidney Injury (AKI) therapy and have certain advantages and disadvantages. Extended daily dialysis (EDD) has emerged as an alternative to CRRT in the management of hemodynamically unstable AKI patients, mainly in developed countries. OBJECTIVES: We hypothesized that EDD is a safe option for AKI treatment and aimed to describe metabolic and fluid control of AKI patients undergoing EDD and identify complications and risk factors associated with death...
