COMPLICATIONS
This study has some limitations. We observed that adherence to the checklist
seems to be a challenge. Thus, to achieve all these benefits, team training is
essential. Part of the study period took place during the COVID-19 pandemic,
which, in addition to delaying data collection and limiting the sample size,
made it necessary to exclude deaths of patients diagnosed with COVID-19 in the
postoperative period, whose complications could lead to biased results. The
absence of thromboelastography in the checklist may have suppressed relevant
intraoperative data and possibly affected the blood transfusion rate. The
individual decision on indication of blood transfusion in cases of borderline
red blood cell indices in this research may have been different from what
occurred in the British research that inspired our study. A larger sample,
through a multicenter study in Brazil, as well as randomization of the study can
improve statistical relevance in the items assessed and refine the analysis of
other variables.
