Figure 4: Red Blood Cell Transfusions During Surgery.

Figure 4:

e-SD = Early Shutdown, d-SD= Delayed Shutdown, Baseline = Baseline Blood Draw, R = reperfusion, Min = Minutes, POD = Post-Operative Day, RBC = Red Blood Cells, P Value represents Kruskal Wallis test across three groups.

The Y axis represents the median number of red blood cells transfused from TEG lab draw to subsequent TEG lab draw. The X Axis represents the different blood draw times. The e-SD (green) group had a significant increase in blood product utilization during the anhepatic phase of surgery with a rapid decrease in blood product utilization for the duration of the blood draws. The other phenotypes did not have significantly different blood product utilization but the total red blood cell transfusions between all three phenotypes was the similar.
