ABSTRACT

Introduction: Acute kidney injury (AKI) is a frequent organ failure in the patient in shock; continuous slow renal replacement therapy (CSRRT) is an extracorporeal support that modifies the patient’s prognosis; the criteria for its initiation as well as for retirement are not completely generalized. The furosemide stress test may be a prognostic marker in patients in whom renal support is withdrawn.
Material and methods: Prospective, observational, analytical and cross-sectional study. Patients with AKI requiring CSRRT were included; 1 mg/kg of furosemide was given to the patients in whom it was decided to withdraw, uresis was quantified at 2, 6 and 24 hours and biochemical variables of renal function were measured. Patients who did not merit CSRRT again during the next seven days were considered successful to the test.
Results: Thirty-one patients connected to TRRLC within the Intensive care unit (ICU), seven were removed for dying within their first day of ICU stay, including a total of twenty four for their study. 45.8% were successful at withdrawal from CSRRT. The 200 mL uresis after the furosemide test has a sensitivity of 64%, a specificity of 100% to predict success on withdrawal and recovery of renal function, with an area under the curve of 0.944.
Conclusion: The presence of 200 mL uresis at 2 hours after administration of furosemide is useful as a predictor of successful withdrawal of TRRLC and recovery of renal function.
