  • Application of Continuous Renal Replacement Therapy in Patients with Acute Renal Insufficiency after Heart Transplantation

    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 venovenous hemodiafiltration(CVVHDF) treatment via M100 blood filter (hemofilters). Activated coagulation time (ACT) was maintained in 160200 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 48658 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 513(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.

  • Effect of Continuous Renal Replacement Therapy on Serum Phosphate Level in Patients after Cardiac Surgery

    ObjectiveTo observe the effect of continuous renal replacement therapy (CRRT) on serum phosphate level in patients after cardiac surgery. MethodA single-center retrospective observational study was conducted on 30 patients received CRRT after cardiac surgery. There were 14 males and 16 females with mean age of 57.0±10.8 years (ranged 37-79 years). A total of 16 patients underwent CRRT with continuous veno-venous hemofiltration (CVVH), and 14 patients with continuous veno-venous hemodiafiltration (CVVHDF). The serum phosphate level was measured before treatment, at 24 h, and 48 h during therapy and 24 h after phosphate salt supplementation. ResultsThe level of serum phosphate at 24 h and 48 h during CRRT was decreased (0.6±0.4 mmol/L vs. 0.4±0.2 mmol/L vs. 1.1±0.3 mmol/L, P<0.01). After intravenous phosphate salt supplementation, serum phosphate level got increased (0.6±0.3 mmol/L, P<0.01). There was no statistical difference in serum phosphate level between CVVH and CVVHDF (P>0.05). ConclusionHypophosphatemia occurs frequently during CRRT, particularly with long treatment time. Phosphate salt supplementation is necessary. The dosage of the supplementation should be adjusted personally based on the regularly monitoring results of serum phosphate tests.

  • Effectiveness of Continuous Renal Replacement Therapy of Acute Kidney Injury after Type A Aortic Dissection Surgery: A Case Control Study

    ObjectiveTo evaluate the efficacy of the continuous renal replacement therapy (CRRT) for acute kidney injury (AKI) after the surgery of type A aortic dissection. MethodsWe retrospectively analyzed 58 hemodialysis patients with AKI after type A aortic dissection surgery in our hospital between January 2003 and January 2014.The 58 patients were divided into two groups including a bedside intermittent hemodialysis (IHD) group and a CRRT group based on the methods of hemodialysis. There were 38 patients with 29 males and 9 females at average age of 49.8± 13.7 years in the CRRT group. There were 20 patients in the IHD group with 14 males and 6 females at average age of 52.6± 11.0 years. ResultsCompared with IHD, CRRT had significantly greater effect on reducing the simplified acute physiology scoring system (SAPS)Ⅱscore (Ftime=60.964, P=0.000; Ftime * group=3.178, P=0.041). However, there was no significant difference in reducing the acute tubular necrosis individual illness severity index (ATN-ISI) score between the two groups (Ftime=13.803, P=0.000; Ftime * group=0.222, P=0.951). Lower incidences of dialysis-related complications including hypotension (P=0.027) and acute congestive heart failure (P=0.011) were found in the CRRT group. There was no statistical difference in operation time (P=0.367) between the two groups. While statistical differences in duration of hospitalization in intensive care unit (P=0.006), in hospital time (P=0.047), frequency of dialysis (P=0.001), and dialysis time (P=0.039) were found between the two groups. However there were no significant differences in mortality during hospital (P=0.544)and incidences of recovery (P=0.056) between the two groups. ConclusionCompared with IHD, CRRT had significantly positive effect on patients who suffered from AKI after type A aortic dissection surgery, which can help reduce incidences of dialysis-related complications, duration and cost of hospitalization in ICU.

  • Risk Factors of Death in Patients Undergoing Continuous Renal Replacement Therapy after Cardiac Surgery

    ObjectiveTo investigate the risk factors of death in patients undergoing continuous renal replacement therapy (CRRT) after cardiac surgery. MethodsWe retrospectively analyzed records of 66 adult patients without history of chronic renal failure suffering acute kidney injury (AKI) following cardiac surgery and undergoing CRRT in our hospital between July 2007 and June 2014. There were 38 males and 28 females with mean age of 59.11±12.62 years. They were divided into a survival group and a non-survival group according to prognosis at discharge. All perioperative data were collected and analyzed by univariate analysis and multivariate logistic regression analysis. ResultsIn sixty-six adult patients, eighteen patients survived with a mortality rate of 72.7%. Through univariate analysis and multivariate logistic regression, risk factors of death in the post-operative AKI patients requiring CRRT included hypotension on postoperative day 1 (B=2.897, OR=18.127, P=0.001), duration of oliguria until hemofiltration (B=0.168, OR=1.183, P=0.024), and blood platelet on postoperative day 1 (B=-0.026, OR=0.974, P=0.001). ConclusionHypotension on postoperative day 1 (POD1) is the predominant risk factor of death in patients requiring CRRT after cardiac surgery, while blood platelet on POD1 is a protective factor. If CRRT is required, the sooner the better.

  • Efficacy comparison between continuous renal replacement therapy and intermittent hemodialysis in the treatment of severe acute renal failure

    Objective To compare the clinical effect of continuous renal replacement therapy (CRRT) and intermittent hemodialysis (IHD) in the treatment of severe acute renal failure (ARF). Methods A hundred patients with severe ARF treated between May 2011 and December 2014 were chosen to be the study subjects. According to the order of admission, they were divided into control group and observation group with 50 patients in each. Patients of the control group underwent IHD, while those in the observation group underwent CRRT. Serum creatinine (Scr), blood urea nitrogen (BUN), endogenous creatinine clearance rate (Ccr), treatment effective rate and survival rate were compared between the two groups before and after the treatment. Results Scr, BUN and Ccr were all improved after treatment in both the two groups. However, Scr, BUN and Ccr in the observation group [(225.1±162.7) μmol/L, (14.2±9.3) mmol/L, (23.4±10.5) mL/min] were significantly better than those in the control group [(588.4±183.6) μmol/L, (29.1±10.4) mmol/L, (15.9±8.2) mL/min]. The treatment effective rate and patients’ survival rate in the observation group were respectively 60% and 70%, both significantly higher than those in the control group (40% and 52%) All the differences were significant (P<0.05). Conclusion CRRT is superior in the treatment of severe ARF with a higher survival rate of the patients, which is worthy of clinical promotion.

  • Influence to blood clotting function of different anticoagulations for continuous renal replacement therapy after cardiopulmonary bypass surgery

    ObjectiveTo research the influence of anticoagulation to blood clotting function in patients who experienced cardiopulmonary bypass surgery under continuous renal replacement therapy (CRRT) with regional citrate anticoagulation (RCA), low molecular weight heparin (LMWH) anticoagulation and non-anticoagulation.MethodsWe retrospectively analyzed the clinical data of 146 patients who underwent CRRT after cardiopulmonary bypass surgery between January 2014 and December 2016. There were 98 males and 48 females at age of 60.51±14.29 years. All CRRT patients were allocated into three groups including a RCA group, a LMWH group, and a non-anticoagulation group, which were compared in terms of convention coagulation tests, platelet counts, thromboelastography, circuit lifespan and transfusion.ResultsThree hundred and fifty four CRRT patients were selected from patients above, including 152 patients in the LMWH group, 160 in the RCA group, and 42 in the non-anticoagulation group. The difference of CRRT circuits time among three groups was statistically different (P=0.023). And multiple comparison showed that the circuit lifespan of the RCA group was significantly longer than that of the non-anticoagulation group (34.50 h ranged 14.00 h to 86.00 h vs.15.00 h ranged 12.00 h to 50.88 h, P=0.033). One hundred and fifty-five CRRT patients last beyond 24 hours with same anticoagulation were selected, the results of coagulation tests, and the difference between CRRT starting and after 24 hours were compared. The difference of Angle and maximum amplitude(MA) of pre- and post-CRRT were significantly different among three groups by one-way ANOVA (P=0.004, 0.000), as well as between the RCA group and the LMWH group by multiple comparison (P=0.004, 0.000). There was no statistical difference in frequencies and doses of the transfusion of fresh frozen plasma and platelet among three groups.ConclusionRCA is an effective anticoagulation which may prolong circuit lifespan and has small impact on the coagulation function of patients who undergo CRRT after cardiopulmonary bypass surgery.

  • 2017 Taiwan continuous renal replacement therapy operational manual for critically ill patients

    Acute kidney injury is a common complication and is associated with multiple organ dysfunction syndrome among critically ill patients in intensive care unit. Once renal replacement therapy in required, the mortality rate was high. Using slow and uninterrupted clearance of retained fluid and toxins, continuous renal replacement therapy (CRRT) can avoid hemodynamic instability while provide acid-base, electrolytes, and volume homeostasis. For decades, CRRT has become the dominant form of renal replacement therapy as well as multiple organ support in critically ill patient with acute kidney injury. However, there remains wide practice variation in the CRRT care when clinicians take into account the needs of individual patients, available resources, and limitations unique to an institution or type of practice, despite evidences to guide practice. In addition, CRRT is a complex technology that is resource-intensive, costly, and requires specialized training by health providers.Taiwan Society of Critical Care Medicine organized a group of experts in critical care and nephrology to review the recommendations and provide their clinical practice and concerns to write this operational manual. The purpose of this manual is to provide step-by-step instructions on the practice of CRRT and troubleshooting. In addition, it is designed to help the newbies to carry out this complex treatment correctly and efficiently. We hope that this operational manual is of value to improve clinical skills, quality of care, and patient safety.

  • Comparison of potassium supplement with infusion pump and traditional potassium supplement in continuous renal replacement therapy

    Objective To explore the feasibility and effect of infusion pump potassium supplementation in continuous renal replacement therapy (CRRT). Methods Patients who underwent CRRT were randomly divided into infusion pump group and traditional way group between March and May 2018. In infusion pump group, 10% potassium chloride was supplemented with infusion pump. In traditional way group, 10% potassium chloride was supplemented in the traditional way, which meant adding potassium in the replacement solution. The peripheral blood potassium level, the potassium well-controlled rate, the incidence of adverse events, the average frequency of replacement liquid bags change, the average pump stopping time, and the delivery dose and potassium supplement dose between the two groups were compared. Results A total of 60 patients were randomly divided into two groups, with 30 cases in each group. The infusion pump group was treated with an average of 6.90 mL/h potassium supplement dose by infusion pump, and in traditional way group, potassium was added to the replacement solution by an average of 9.29 mL/h; there were significant differences between the two groups (P<0.05). When compared with traditional way group, there was no significant differences (P>0.05) in the peripheral blood potassium level and the potassium well-controlled rate of the patients at 0, 2, 8, 12 and 24 hours after CRRT (P>0.05). As for the adverse events rate, average frequency of replacement liquid bags change, average pump stopping time, and potassium supplement dose, there were significant differences between the two groups (P<0.05). Conclusions The application of infusion pump to supply potassium in CRRT is feasible and safe, and is superior to the traditional potassium supplement method. It could be further applied in clinical practice.
