ABSTRACT
La hemofiltración venovenosa continua (HFVVC), es unatécnica realizada en pacientes postoperados de cirugía cardíaca;consiste en extraer agua plasmática del sistema circulatorio,a través de una membrana semipermeable (hemoconcentrador)por convección y gradiente de presión, con el objetivode disminuir hipervolemia, mejorar la función renal, eliminarmediadores de respuesta inflamatoria y optimizar el estado hemodinámicode los pacientes. Este procedimiento es realizadopor el personal de enfermería de perfusión en la unidad de terapiaintensiva con un circuito que se arma y diseña en unárea blanca. Una de las principales ventajas que se le adjudicana las terapias de HFVVC, es la tolerancia hemodinámica ala extracción de grandes volúmenes de líquido en forma gradualy controlada, en pacientes en estado crítico.
The continuous veno-venous hemofiltration (HFVVC), is atechnique realized in post-operated patients of cardiac surgery;it consists of extracting plasmatic water of the circulatorysystem, through a semi permeable membrane (hemoconcentrador)by convection and pressure gradient, with the aimof diminishing hipervolemia, improving the renal function,to eliminate mediators of inflammatory answer and to optimizethe hemodinámico state of the patients. This procedureis realized by the personnel of perfusion infirmary in theunit of intensive therapy with a circuit that weapon and isdesigned in a white area. One of the main advantages thatare adjudged to the HFVVC therapies, is the tolerance haemodynamicsto the extraction of great volumes of liquid ingradual and controlled form, in patients in critical state.

Cardiac surgery has evolved greatly in the last pears. New techniques for the treatment of cardiac patients, such as minimally invasive heart surgery, off-pump coronary surgery, limited or port access surgery, video-assisted and robotic cardiac surgery have been developed. Technology provides new instruments, such as heart stabilizers for off-pump coronary surgery, ventricular support devices or direct coronary bypass perfusion systems, all of them with the main goal of maintaining the patient's hemodynamics. Minimally invasive heart surgery contributes to a faster recovery and less suffering, and decreases costs. The perfusionist is involved in all these new techniques, the future is a challenge, he she must learn to use all these new devices without forgetting the human sede of his her specialty.
