ObjectiveTo assess the indications, settings and techniques used in renal replacement therapy (RRT) in Intensive Care Units (ICUs).Study DesignA prospective, multicenter observational study was carried out.SettingIntensive Care Units.PatientsAll patients admitted to ICUs during the two-month study period in 2011 who required RRT.InterventionsNone.Variables Of InterestPatient demographic characteristics, baseline clinical data, RRT technique and materials used.ResultsThirty-three patients were analyzed. RRT was started within the first 24hours after ICU admission in 17 of the 33 patients (52%). At the start of RRT, 18% of the patients (n=6) presented grade R on the RIFLE acute kidney injury (AKI) scale. The most common disorder associated with AKI was multiple organ dysfunction syndrome (64%; n=21). At the start of RRT, most patients (76%; n=25) presented hemodynamic instability, while the remaining 24% (n=8) were considered hemodynamically stable. The most common RRT technique in hemodynamically stable patients was continuous renal replacement therapy (CRRT) (63%; n=5). CRRT was the technique of choice in all 25 of the hemodynamically unstable patients (100%). Anticoagulation was used in 55% (n=18) of the patients. In most cases (61%, n=20), RRT was administered through the right femoral vein. In 84% (n=28) of the patients, the ultrafiltration effluent flow rate was ≤ 35ml/kg/h.ConclusionsThe ICU physicians in this study followed current RRT guidelines. CRRT was preferred over intermittent renal replacement therapy, regardless of patient hemodynamic status.Copyright © 2013 Elsevier España, S.L.U. and SEMICYUC. All rights reserved.
