Background: Impairment of renal function is a serious complication in critically ill patients. Mortality of acute renal failure remains high ranging from 35% to 86% despite haemodialysis therapy and substantial improvement of dialysis techniques. Therefore attention must be paid to the conditions favouring deterioration of renal function in order to prevent acute renal failure or to intervene in an early phase when less invasive therapies might be even more promising. Methods: This prospective study was conducted in a tertiary care teaching hospital in Mumbai from 1st January 2006 to 31st December 2006. All patients consecutively admitted in intensive care unit were studied. Results: Total number of patients admitted during the said period to the Intensive care Unit was 406, of which 50 had evidence of acute renal failure. The incidence of acute renal failure in the critically ill patients included in our study was 12.31%. There was a statistically significant difference in the incidence of fluid overload, oliguria and hyperkalemia between the pre-renal and renal failure groups. Conclusion: The incidence of acute renal failure in the critically ill patients was 12.31% and commonest predisposing factors associated with acute renal failure were acute insults like hypotension, sepsis and risk factors like age >50 years and pre-existing renal disease.

CONTEXT AND OBJECTIVE: Acute renal failure is a common medical problem, with a high mortality rate. The aim of this work was to investigate the risk factors for death among critically ill patients with acute renal failure. DESIGN AND SETTING: Retrospective cohort at the intensive care unit of Hospital Universitário Walter Cantídio, Fortaleza. METHODS: Survivors and non-survivors were compared. Univariate and multivariate analyses were performed to establish risk factors for death. RESULTS: Acute renal failure occurred in 128 patients (33.5%), with mean age of 49 ± 20 years (79 males; 62%). Death occurred in 80 (62.5%). The risk factors most frequently associated with death were hypotension, sepsis, nephrotoxic drug use, respiratory insufficiency, liver failure, hypovolemia, septic shock, multiple organ dysfunction, need for vasoactive drugs, need for mechanical ventilation, oliguria, hypoalbuminemia, metabolic acidosis and anemia. There were negative correlations between death and: prothrombin time, hematocrit, hemoglobin, systolic blood pressure, diastolic blood pressure, arterial pH, arterial bicarbonate and urine volume. From multivariate analysis, the independent risk factors for death were: need for mechanical ventilation (OR = 3.15; p = 0.03), hypotension (OR = 3.48; p = 0.02), liver failure (OR = 5.37; p = 0.02), low arterial bicarbonate (OR = 0.85; p = 0.005), oliguria (OR = 3.36; p = 0.009), vasopressor use (OR = 4.83; p = 0.004) and sepsis (OR = 6.14; p = 0.003). CONCLUSIONS: There are significant risk factors for death among patients with acute renal failure in intensive care units, which need to be identified at an early stage for early treatment.

The purpose of this study was to evaluate the efficacy and safety of danaparoid in the treatment of critically ill patients with acute renal failure and suspected heparin-induced thrombocytopenia (HIT) needing renal replacement therapy (RRT). We conducted a retrospective analysis of 13 consecutive intensive care patients with acute renal failure and suspected HIT who were treated with danaparoid for at least 3 days during RRT. In eight patients, continuous venovenous hemofiltration was performed. The mean infusion rate of danaparoid was 140 ± 86 U/hour. Filter exchange was necessary every 37.5 hours. In five patients, continuous venovenous hemodialysis was used. A bolus injection of 750 U danaparoid was followed by a mean infusion rate of 138 ± 122 U/hour. Filters were exchanged every 24 hours. In 7 of 13 patients, even a low mean infusion rate of 88 ± 35 U/hour was efficient. Mean anti-Xa (aXa) levels were approximately 0.4 ± 0.2 aXa U/mL. Persistent thrombocytopenia despite discontinuation of heparin treatment was observed in 9 of 13 patients, owing to disseminated intravascular coagulation (DIC). HIT was confirmed by an increase in platelet count and positive heparin-induced antibodies in 2 of 13 patients. No thromboembolic complications occurred, but major bleeding was observed in 6 of 13 patients, which could be explained by consumption of coagulation factors and platelets due to DIC in 5 of 6 patients. Nine of 13 patients died of multiorgan failure or sepsis, or both. In none of these patients was the fatal outcome related to danaparoid treatment. In critically ill patients with renal impairment and suspected HIT, a bralus injection of 750 U danaparoid followed by a mean infusion rate of 50 to 150 U/hour appears to be a safe and efficient treatment option when alternative anticoagutation is necessary.

Background. The aim of this study was to investigate whether different haemofilter surface areas affect clotting and platelet consumption in critically ill patients undergoing continuous venovenous haemodiafiltration (CVVHDF).Methods. CVVHDF was performed in postdilution technique using a capillary haemofilter with two different membrane sizes, Ultraflux AV 1000S (n=17, surface 1.8 m2, volume 130 mL), and the smaller AV 600S (n=16, surface 1.4 m2, volume 100 mL), respectively. Anticoagulation was performed with heparin.Results. No significant differences were found when the two filters were compared. CVVHDF was performed for 33 (7–128) hours with the filter AV 1000S and 39 (7–97) hours with AV 600S (P=0.68). Two (1–4) filters were utilised in both groups over this observation period (P=0.94). Platelets dropped by 52,000 (0–212,000) in AV 1000S group and by 89,500 (0–258,000) in AV 600S group (P=0.64). Haemoglobin decreased by 1.2 (0–2.8) g/dL in AV 1000S group and by 1.65 (0–3.9) g/dL in AV 600S group (P=0.51), leading to the transfusion of 1 (0–4) unit of blood in 19 patients (10 patients with AV 1000S and 9 with AV 600S). Filter observation was abandoned due to death (12.1%), need for systemic anticoagulation (12.1%), repeated clotting (36.4%), and recovery of renal function (39.4%).Conclusion. Our study showed that a larger filter surface area did neither reduce the severity of thrombocytopenia and anaemia, nor decrease the frequency of clotting events.

We aimed to clarify associations between nutritional status and mortality in patients with acute renal failure. De-identified data were obtained from the Medical Information Mart for Intensive Care III database comprising more than 40,000 critical care patients treated at Beth Israel Deaconess Medical Centerbetween 2001 and 2012. Weight loss and body mass index criteria were used to define malnutrition. Data of 193 critically ill patients with acute renal failure were analyzed, including demographics, nutrition intervention, laboratory results, and disease severity. Main outcomes were in-hospital and 1-year mortality. The 1-year mortality was significantly higher in those with malnutrition than in those without malnutrition (50.0% vs 29.3%, p=0.010), but differences in in-hospital survival were not significant (p=0.255). Significant differences in mortality were found between those with malnutrition and without starting at the 52nd day after intensive care unit (ICU) discharge (p=0.036). No significant differences were found between men and women with malnutrition in in-hospital mortality (p=0.949) and 1-year mortality (p=0.051). Male patients requiring intervention with blood products/colloid supplements had greater risk of 1-year mortality, but without statistical significance. Nutritional status is a predictive factor for mortality among critically ill patients with acute renal failure, particularly 1-year mortality after ICU discharge.
