[Maximum surgical blood ordering schedule for cardiac surgery]

Blood donation is a resource of great value; it is essential to ensure its correct and reasonable use. An excessive and unjustified demand for blood leads to an increase in cross matching and loss of components; Therefore, it is crucial to guarantee its proper use through the development of a maximum blood order program for surgery.

Develop and implement a maximum surgical blood order program at the Hospital de Cardiología, Centro Médico Nacional Siglo XXI.

Observational, longitudinal, ambispective and comparative study, carried out for 1 year. All patients undergoing cardiac surgeries were included. The crossed and transfused erythrocyte concentrates were counted. Crossover/transfusion ratio (C/T), probability of transfusion (T%), and transfusion index (TI) were calculated. Descriptive statistics were used, calculated from the MSBOS and analysis with the Wilcoxon test.

58 types of elective surgeries were categorized with a total of 533 surgeries performed. When comparing the CT, T% and TI indices between the periods, improvement was obtained in the following surgeries: hemodynamic ablation, ASD closure, decortication, MCP, tracheostomy, heart transplantation and pericardial window.

An MSBOS was developed in a Cardiology Hospital and an improvement was found in the evaluated indices. The implementation of the program allows evaluating the proper administration of blood components.
