To study the effect of intraoperative blood loss on postoperative outcomes in patients with aneurysm and/or dissection of ascending aorta and aortic arch.
A retrospective analysis included 77 patients (mean age 52.8±11.4 years). All ones underwent ascending aorta and aortic arch replacement under cardiopulmonary bypass and antegrade cerebral perfusion with hypothermia (mean 23.9±3.2 °C) for aneurysm and/or dissection. To identify the relationship between blood loss and incidence of organ dysfunctions, we used the original parameter, i.e. blood loss index (intraoperative blood loss / weight / surgery time) (ml/kg/hour).
There was a significant correlation between blood loss index and postoperative organ dysfunctions (r=0.57, p<0.001). At the same time, we found no correlation between overall blood loss and postoperative organ dysfunctions (r=0.23, p=0.23). According to the ROC curve, the cut-off values were 2.9 ml/kg/hour for respiratory failure, 3.1 ml/kg/hour for cardiovascular failure and 6 ml/kg/hour for multiple organ failure. Sensitivity of each point was 72%, 81% and 84%, specificity 59%, 59% and 64%, respectively.
Blood loss index is valuable to predict organ dysfunctions after ascending aorta and aortic arch surgery. The conditionally «safe» blood loss index is less than 3 ml/kg/hour.
