ARISTIZABAL LINARES, Juan Pablo. Blood storage and transfusion injury. []. , 40, 4, pp.266-267. ISSN 0120-3347.  https://doi.org/10.1016/j.rca.2012.07.003.

Introduction: The purpose of this paper is to offer some thoughts regarding the review article «Blood-sparing surgical techniques» published by doctors Rivera and Perez, and to comment some relevant aspects pertaining to red blood cell transfusions. Methods:After reading the review article on «Blood-sparing surgical techniques», a literature search was done of articles related to blood product transfusions and their complications. Comments are made to complement the paper by doctors Rivera and Pérez. Results: The literature recommends adopting a conservative attitude as far as the use of blood products is concerned, and to always individualize and assess the patient's own clinical and tissue perfusion status. There is no consensus regarding hemoglobin values, which range between 6 and 10g/dL. Conclusion: The decision to transfuse or not must be based on the patient's own individual parameters, clinical assessment, hemodynamic and tissue status. Studies are still needed regarding the value range between 6-10 g/dL.
