Methods
Perioperative blood conservation measures were established in our
institution in 2012. Medical records that included transfusion data and
clinical outcomes of patients who underwent isolated primary CABG from
2009 to 2012 (group A) and 2013 to 2016 (group B) were compared. Most
operations were performed by a single surgeon (RA). Clinical outcomes
(mortality, morbidity, and postoperative length of stay) and
transfusions were measured as endpoints. Groups were compared using
simple descriptive statistics and a chi-square test or Wilcoxon rank sum
test as appropriate. A p-value <.05 was considered
significant.
