Objective To summarize and analyze the clinical outcomes and experiences of continuous renal replacement therapy(CRRT) in patients with acute renal insufficiency after heart transplantation. Methods There were 39 patients received orthotopic heart transplantation from September 2007 to September 2008 in Fu Wai hospital. Seven cases required the use of PRISMA CRRT machine (Gambro Healthcare,Inc.) because of acute renal insufficiency after heart transplantation, and received continuous venovenous hemodiafiltration(CVVHDF) treatment via M100 blood filter (hemofilters). Activated coagulation time (ACT) was maintained in 160200 s. Results Six survivals with New York Heart Association (NYHA)Ⅰdischarged ，1 case died of multiple system organ failure (MSOF) and severe infection. The time of CRRT was 48658 h, with an average of 252 h. Seven patients were oliguric or anuric during CRRT, but hemodynamics and internal environment were stable. After stopping CRRT, the creatinine level rose to 267.1±68.5 μmol/L， then the creatinine level decreased to normal range with urine increasing gradually. Postoperative glomerular filtration rate (GFR) was 56.5±19.0 ml/min， and there was no statistical significance compared with preoperative GFR（Pgt;0.05）. Six survivals were followed up for 513(9.7±3.8)months，and their creatinine level was in normal range(90.6±26.7 μmol/L). There was no statistical significance compared with the creatinine level at discharge (83.2±26.5 μmol/L, Pgt;0.05）. Conclusion The prognostic outcomes of patients with acute renal insufficiency after heart ransplantation are excellent after using CRRT. No significant renal dysfunction is found.
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.
Continuous renal replacement therapy (CRRT) is the treatment of choice for critically ill patients with hemodynamic instability who require renal replacement therapy. This review summarizes the impact of CRRT treatment on nutritional support in critically ill patients, including: energy increase caused by citrate-based anticoagulants, energy loss caused by glucose-free replacement fluid and dialysate, a large amount of amino acids loss in the effluent, and the influences on the way of lipid emulsion administration, capacity, electrolyte, vitamins, and trace elements. It is hoped that the intensive care unit doctors, nephrologists, and nutritionists can fully cooperate to determine the CRRT prescription and the nutritional support prescription.
Objective To explore the risk factors affecting the prognosis of patients with acute kidney injury (AKI) after extracorporeal circulation surgery who receive continuous renal replacement therapy (CRRT). Methods Patients who developed AKI and underwent CRRT treatment after extracorporeal circulation surgery at the First Affiliated Hospital of Chongqing Medical University between May 2019 and May 2024 were retrospectively selected. According to the prognosis, patients were divided into the good prognosis group and the poor prognosis group. Basic information, duration of extracorporeal circulation during surgery, aortic occlusion time, timing and duration of CRRT initiation therapy, relevant laboratory indicators before surgery, during CRRT intervention, and upon discharge or death were collected. The risk factors affecting the prognosis of such patients were analyzed. Results A total of 45 patients were included. Among them, there were 20 cases in the good prognosis group and 25 cases in the poor prognosis group. There was no statistically significant difference in the basic information between the two groups (P>0.05). Compared with the poor prognosis group, the good prognosis group had decreased preoperative urea nitrogen and increased hemoglobin levels, reduced levels of alanine aminotransferase and aspartate aminotransferase during the initiation of CRRT treatment, and reduced levels of white blood cell count, neutrophil percentage, alanine aminotransferase and aspartate aminotransferase and elevated platelet count before discharge or death (P<0.05). The results of multivariate logistic regression analysis showed that the total duration of CRRT treatment [odds ratio (OR)=1.007, 95% confidence interval (CI) (1.000, 1.015), P=0.046], white blood cell count before discharge or death [OR=1.541, 95%CI (1.011, 2.349), P=0.044], and platelet count before discharge or death [OR=0.964, 95%CI (0.937, 0.991), P=0.010] could affect patient prognosis. Conclusions In patients with AKI after extracorporeal circulation surgery, if combined with renal dysfuction and anemia before surgery, liver function damage and secondary infection during CRRT initiation therapy may be related to poor patient prognosis. The longer the duration of CRRT treatment, the higher the white blood cells before discharge or death, and the lower the platelet count are independent risk factors for poor prognosis in patients.
Objective To analyze the risk factors for death in children with interruption of aortic arch (IAA) and ventricular septal defect (VSD) after one-stage radical surgery. Methods A retrospective analysis was performed on patients with IAA and VSD who underwent one-stage radical treatment in the First Hospital of Hebei Medical University from January 2006 to January 2017. Cox proportional hazards regression model was used to analyze the risk factors for death after the surgery. Results A total of 152 children were enrolled, including 70 males and 82 females. Twenty-two patients died with a mean age of 30.73±9.21 d, and the other 130 patients survived with a mean age of 37.62±11.06 d. The Cox analysis showed that younger age (OR=0.551, 95%CI 0.320-0.984, P=0.004), low body weight (OR=0.632, 95%CI 0.313-0.966, P=0.003), large ratio of VSD diameter/aortic root diameter (VSD/AO, OR=2.547, 95%CI 1.095-7.517, P=0.044), long cardiopulmonary bypass time (OR=1.374, 95%CI 1.000-3.227, P=0.038), left ventricular outflow tract obstruction (LVOTO, OR=3.959, 95%CI 1.123-9.268, P=0.015) were independent risk factors for postoperative death. Conclusion For children with IAA and VSD, younger age, low body weight, large ratio of VSD/AO, long cardiopulmonary bypass time and LVOTO are risk factors for death after one-stage radical surgery.
Objective To explore the global research status and trends of continuous renal replacement therapy (CRRT) based on knowledge visualization analysis. Methods Based on the Web of Science Core Collection, studies reporting CRRT research that were published between June 2014 and June 2023 were retrieved and collected after manual review. VOSviewer and CiteSpace softwares were used for bibliometric visualization analysis, including publication trends, geographical distribution characteristics, journal distribution characteristics, author contributions, citations, funding source characteristics, and keyword clustering. Results A total of 2708 papers were analyzed, with an increasing trend in the number of articles and citation frequency from 2015 to 2021. The United States was the most prolific country and France was the most influential country. The University of Pittsburgh in the United States had the highest number of publications among research institutions and showed higher motivation for inter-institutional collaboration. The University of Queensland in the Australia had the highest average citation frequency. Professor Rinaldo Bellomo of Australia was the most productive author and Professor Jeffrey Lipman was the most influential. Jason A. Roberts, Jeffrey Lipman and Claudio Ronco were the three authors who had the highest number of collaborations with other authors. Keyword cluster analysis showed that the prognosis of CRRT for renal disease was the focus of research, with hotspots of research being antibiotics, citrate accumulation, plasma replacement, lactate clearance, acute respiratory distress syndrome, and coronavirus disease 2019. Coupling analysis of the literature showed that exploring the indications for CRRT and optimizing treatment prescription were at the forefront of research. Conclusions The present study of CRRT has generally shown an upward trend in the last decade. The management and efficacy of CRRT remains a hot topic of research. Exploring the indications for CRRT and optimizing treatment prescriptions may be a popular research direction and trend in the future.
Rhabdomyolysis-induced acute kidney injury (RIAKI) is a serious clinical disease in intensive care unit, characterized by high mortality and low cure rate. Continuous renal replacement therapy (CRRT) is a common form of treatment for RIAKI. There are currently no guidelines to guide the application of CRRT in RIAKI. To solve this problem, this article reviews the advantages and limitations of CRRT in the treatment of RIAKI, as well as new viewpoints and research progress in the selection of treatment timing, treatment mode, treatment dose and filtration membrane, with the aim of providing theoretical guidance for the treatment of CRRT in RIAKI patients.
