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.
