LLANES ECHEVARRIA, José R. Soluciones cristaloides y coloides, como sustitutas de la sangre en el cebado del circuito extracorpóreo durante la cirugía cardiovascular. Rev Cubana Cir [online]. 2002, vol.41, n.1, pp. 42-46. ISSN 1561-2945.

The chief characteristics, objectives of application and the advantages the colloidal and electrolytic solutions used in the priming of the extracorporeal circuit offer are explained in this qualitative study. The necessary arguments that allow the perfusionist to combine certain solutions to conserve osmolarity, the oncotic pressure of plasma, to improve the microcirculatory flow and to avoid blood transfusions and unnecessary hemoderivatives, are dealt with as the fundamental aim. Reference is made to different techniques used to conserve the haematocrit level, such as: the use of haemofilters, cell concentrator and the application of blood cardioplegia, whose main goal is the myocardial protection, but it also substitutes the great volumes of fluid that characterize the use of crystalloid cardioplegia
