Objectives to evaluate the renal function of patients in an intensive care unit, to
identify the predisposing factors for the development of renal failure, and
to develop an algorithm to help in the control of the disease. Method exploratory, descriptive, prospective study with a quantitative
approach.Results a total of 30 patients (75.0%) were diagnosed with kidney failure and the
main factors associated with this disease were: advanced age, systemic
arterial hypertension, diabetes mellitus, lung diseases, and antibiotic use.
Of these, 23 patients (76.6%) showed a reduction in creatinine clearance in
the first 24 hours of hospitalization. Conclusion a decline in renal function was observed in a significant number of
subjects, therefore, an algorithm was developed with the aim of helping in
the control of renal failure in a practical and functional way.
