| dc.description.abstract | Introduction
Transfusion medicine develops and disseminates guidelines that govern the optimal conditions for
transfusion. The purpose of this article is to review the current evidence on the use of blood components.
Methods
We searched PubMed, Scholar Google, ScienceDirect, SciELO and Cochrane web portals, as well as
official documents published in the Chilean Society of Hematology. Articles from the last ten years were
included, of which 42 were appropriate for this narrative literature review.
Conclusion
First of all, there is a controversy between two types of strategies regarding the practice of red blood cell
transfusion: a liberal strategy and a restrictive strategy. Second, for the management of coagulopathies,
clotting times do not reflect the true ability of patients to clot. Third, to reverse the effect of coumadin,
the administration of vitamin K would suffice over the use of fresh frozen plasma. Fourth, the use of
physiological triggers could help define the best time for a transfusion. | |
