  • Continuous renal replacement therapy for special types of acidosis

    Continuous renal replacement therapy (CRRT) is a term of blood purification technique that can continuously remove the body's solute and water for 24 hours without any interruption throughout each day. It has several advantages such as hemodynamic stability, accurate capacity control, stable internal environment, and inflammatory regulation, which is especially suitable for patients with severe hemodynamic instability. In clinical practice, critically ill patients treated with CRRT are often associated with different types of acidosis, including metabolic acidosis, lactic acidosis, citrate acidosis, ketoacidosis and hypercapnic acidosis. Different types of acidosis can be treated in different ways. This paper reviews the CRRT for special types of acidosis.

  • Vascular access and complications in renal replacement therapy: a Meta-analysis

    ObjectiveTo compare dialysis catheter function and complications according to catheter site in patients undergoing hemopurification.MethodsLiteratures were searched from PubMed, Medline, Embase, Cochrane Library, Chinese National Knowledge Infrastructure, Wanfang Data, and VIP Database according to the inclusion and exclusion criteria. Publication years of these literatures ranged from April 1998 to April 2018. Meta-analysis was performed with RevMan 5.3 software. The odds ratio (OR) and 95% confidence intervals (CI) were calculated for uncontinuous outcomes, and the weighted mean difference (WMD) and 95%CI were calculated for continuous outcomes. The incidence of catheter related infection, other complications and patients outcome were compared between different sites for dialysis vascular access.ResultsA total of 9 articles were included, including 2 randomized controlled trials and 7 observational clinical studies, and 5 220 adult patients undergoing renal replacement therapy. Meta-analysis showed that there was no significant difference in incidences of catheter colonization or catheter-related bloodstream infection, as well as arterial puncture, local thrombosis, catheter dysfunction and spontaneous catheter withdrawal, between femoral and non-femoral (jugular or subclavian) catheterization (P≥0.05). Whereas the incidence of bleeding and local hematoma was lower in femoral catheterization [OR=0.44, 95%CI (0.23, 0.82), P=0.009], and the duration of catheters was shorter in femoral catheterization [WMD=–1.40 d, 95%CI (–2.17, –0.62) d, P=0.000 4]. The blood flow rate, filters clotting incidence and patients intensive case unit mortality were similar in different catheterization.ConclusionsIn patients undergoing renal replacement therapy, the bleeding and local hematoma incidence is lower in femoral catheterization but the duration of catheters is shorter. Nevertheless the patients have similar clinical outcome. This result may provide reference for clinical decision-making.

  • Simplified regional citrate anticoagulation in sustained low efficiency dialysis

    Objective To evaluate the safety and efficacy of simplified regional citrate anticoagulation in sustained low efficiency dialysis (SLED). Methods We prospectively analyzed the patients with acute kidney injury or end stage renal disease in Department of Nephrology, West China Hospital of Sichuan University from March 2017 to May 2018. All the patients received SLED treatment by Fresenius 4008s ARrTplus through either femoral or internal jugular venous catheter, with each session of SLED treatment lasting for 8 to 10 hours. We pumped in 4% tri-sodium citrate solution through the arterial line at 300 mL/h and citrate infusion was stopped 15 minutes before ending of treatment. The blood flow was 150 mL/min while the calcium-containing dialysate (Ca 1.25 mmol/L) was delivered at 200 mL/min. We recorded peripheral, post filter ionized calcium level, and systemic citrate concentration at 0, 2 and 6 hours, respectively. Results Sixty-two patients underwent 185 sessions of SLED. Three sessions of two patients were discontinued for filter clotting, while the rest 182 SLED sessions (98.4%) were all successfully completed. The systemic citrate concentrations at 2 and 6 hours after beginning were of no statistical difference [(0.82±0.31) vs. (0.86±0.31) mmol/L, P=0.21]. The 0-, 2-, 6-hour peripheral blood ionized calcium levels were (1.12±0.21), (1.09±0.12), and (1.11±0.09) mmol/L, respectively, with no significant difference (P>0.05), and post filter ionized calcium at 2 and 6 hours after beginning were recorded as (0.35±0.06) and (0.31±0.04) mmol/L. The trans-membrane pressure at 2 and 6 hours after beginning were (106.2±13.8) and (105.3±22.4) mm Hg (1 mm Hg=0.133 kPa), with no significant difference (P=0.42). At 6 hours after beginning, prothrombin time and activated partial thrombin time were identified to be similar to those before SLED. During SLED treatments, in 4 sessions (2.2%), patients suffered mild metabolic alkalosis, but all of them recovered 4 hours later by themselves. No bleeding complication, thrombocytopenia, cardiac arrhythmia, hypernatremia, metabolic alkalosis or hypotension was observed. Conclusion SLED under simplified citrate anticoagulation is safe and effective by using calcium containing dialysate, which achieves satisfying regional anticoagulation effect without interfering systemic clotting function, and provides a new option of anticoagulation for SLED.
