Introduction:

continuous renal replacement therapy is a novel procedure that is applied to the treatment of acute renal failure in critically ill patients, as well as systemic inflammatory response syndrome. It is preferably applied in those patients with hemodynamic deterioration in whom intermittent dialysis treatment can be harmful due to the relative speed with which replacement occurs. However, there is no consensus regarding its early use.

Objective:

to present the case of a seriously ill patient who underwent early continuous renal replacement therapy.

Case report:

a 48-year-old patient, with a history of grade V chronic kidney disease, on an intermittent hemodialysis regimen, high blood pressure and obesity, who was admitted to the Cardiovascular Intensive Care Unit of the Hermanos Ameijeiras Hospital in the immediate postoperative period and complicated by aortic valve replacement surgery; in which early continuous renal replacement therapy turned out to be efficient for the treatment of acute chronic renal failure, since it allowed maintaining good control of hemodynamics, the internal environment and blood volume.

Conclusions:

the experience shown provides elements in favor of the safety of the treatment, which makes it recommendable in the seriously ill patient after cardiovascular surgery, as part of the therapeutic arsenal to be used.
