Introduction: Fluid therapy in critically ill patients, especially timing and fluid choice, is controversial. Previous randomized trials produced conflicting results. This observational study evaluated the effect of colloid use on 90-day mortality and acute kidney injury (RIFLE F) within the Rational Fluid Therapy in Asia (RaFTA) registry in intensive care units. Materials and methods: RaFTA is a prospective, observational study in Asian intensive care unit (ICU) patients focusing on fluid therapy and related outcomes. Logistic regression was performed to identify risk factors for increased 90-day mortality and acute kidney injury (AKI). Results: Twenty-four study centers joined the RaFTA registry and collected 3,187 patient data sets from November 2011 to September 2012. A follow-up was done 90 days after ICU admission. For 90-day mortality, significant risk factors in the overall population were sepsis at admission (OR 2.185 [1.799; 2.654], p < 0.001), cumulative fluid balance (OR 1.032 [1.018; 1.047], p < 0.001), and the use of vasopressors (OR 3.409 [2.694; 4.312], p < 0.001). The use of colloids was associated with a reduced risk of 90-day mortality (OR 0.655 [0.478; 0.900], p = 0.009). The initial colloid dose was not associated with an increased risk for AKI (OR 1.094 [0.754; 1.588], p = 0.635). Conclusion: RaFTA adds the important finding that colloid use was not associated with increased 90-day mortality or AKI after adjustment for baseline patient condition. Clinical significance: Early resuscitation with colloids showed potential mortality benefit in the present analysis. Elucidating these findings may be an approach for future research.

Objectives: In critically ill patients, acute kidney injury (AKI) and sepsis often coexist. This confounds the assessment of outcomes of both sepsis and AKI in these patients. Hence, in this study, we compare the outcomes of AKI with sepsis, AKI without sepsis, and sepsis without AKI against a control cohort comprising patients with neither AKI nor sepsis. Materials and methods: Prospective observational study conducted in our critical care unit (CCU) between January and July 2009. Data including demographic details, acute physiology and chronic health evaluation (APACHE) III score, presence of AKI, presence of sepsis, intensive care unit (ICU) length of stay (LOS), and outcomes were collected for all patients. Acute Kidney Injury Network (AKIN) criteria were used to define the presence of AKI and American College of Critical Care Medicine 2001 definition was used to define the presence of sepsis. Results: A total of 250 patients were included in the study and 8 patients were excluded from analysis as they were discharged from hospital against medical advice. The remaining 242 patients (mean age 52.8 ± 17 years; 61.6% male; APACHE III score: 48.2 ± 24.1) were analyzed, and AKI was seen in 111 patients (45.8%). Among the patients with AKI, 55.8% (62/111) had sepsis and 44.2% (49/111) had nonseptic AKI. There was a higher need for renal replacement therapy (RRT) among patients with septic AKI in comparison to those with nonseptic AKI (19.3% vs 6.1%; p = 0.04), but no mortality difference was seen between the two groups (25.8% vs 20.4%, p = 0.5). Patients with sepsis and AKI had a significantly higher mortality (25.8%) compared to the patients with sepsis alone (5.6%; p < 0.01). Conclusion: Patients with septic AKI had a higher RRT requirement compared to patients with nonseptic AKI, but no significant differences in mortality were seen between the groups. Occurrence of AKI in septic patients substantially increases their mortality. [ABSTRACT FROM AUTHOR]

Aim: Recent advances in dialysis therapy have made an impact on the clinical practice of renal replacement therapy (RRT) in acute kidney injury (AKI) in Intensive Care Unit (ICU). We studied the impact of RRT practice changes on outcomes in AKI in ICU over a period of 8 years. Subjects and Methods: AKI patients requiring RRT in ICU referred to a nephrologist during two different periods (period-1: Between May 2004 and May 2007, n = 69; period-2: Between August 2008 and May 2011, n = 93) were studied. The major changes in the dialysis practice during the period-2, compared to period-1 were introduction of prolonged intermittent RRT (PIRRT), early dialysis for metabolic acidosis, early initiation of RRT for anuria and positive fluid balance and use of bicarbonate-based fluids for continuous RRT (CRRT) instead of lactate buffer. The primary study outcome was 28-day hospital mortality. Results: The mean age was 53.8 ± 16.1 years and 72.6% were male. Introduction of PIRRT resulted in 37% reduction in utilization of CRRT during period-2 (from 85.5% to 53.7%). The overall mortality was high (68%) but was significantly reduced during period-2 compared to period-1 (59% vs. 79.7%, P = 0.006). Metabolic acidosis but not the mode of RRT, was the significant factor which influenced mortality. Conclusions: Adaption of PIRRT resulted in 37% reduction of utilization of CRRT. The mortality rate was significantly reduced during the period of adaption of PIRRT, possibly due to early initiation of RRT in the latter period for indications such as anuria and metabolic acidosis.
