Laboratory Predictors of Blood Loss
We evaluated several laboratory parameters to determine if they were
could be predictive of blood loss (Table 6). Minimum intraoperative
platelet count was predictive of both intraoperative and postoperative
calculated blood loss. Minimum intraoperative fibrinogen and maximum PT
were predictive of intraoperative blood loss, while maximum
intraoperative PTT was predictive of postoperative blood loss.
Postoperative laboratory values were not predictive of postoperative
blood loss.
