New Protocol With Diluted Citrate in Continuous Techniques

Study design: quasi-experimental design. two groups: 1. Usual protocol with Multifiltrate monitor and citrate (136 mmol/l) 2. Intervention group. New protocol with Prismaflex monitor and citrate (18 mmol/l) Study population Inclusión/exclusion criteria: Adult patients (regardless of their underlying pathology), who develop acute renal failure, admitted to the ICU of St Pau Hospital with the Intensive Medicine medical team, who require citrate anticoagulation in continuous dialysis therapy and are treated with Baxter "Prismaflex" monitor. Patients who meet the criteria described above will be followed up in this study. Expected sample size: It is estimated that with 24/12 (group1/2) patients will be enough to achieve our goal Methodology. Information sources: The start of the treatment with Baxter citrate will be given according to the patient's need and subject to a basic medical decision. From here the research team will enter. The investigation team will never influence the medical decision. Since such a treatment is started, the main investigator will assign a number to the dialysis circuit and will be followed, every six hours, for the most important variables. The rest of the variables will be collected at least once a day and according to the patient's situation.
