Increased Transfusion of Fresh Frozen Plasma is Associated with Mortality or Worse Functional Outcomes After Severe Traumatic Brain Injury: A Retrospective Study
World Neurosurgery(2017)
Abstract
BACKGROUND: The fresh frozen plasma (FFP) transfusion threshold and timing for traumatic brain injury (TBI)-associated coagulopathy are controversial. Thus, a multicenter retrospective study was conducted to determine whether or not FFP transfusion is associated with poor outcomes after severe TBI. METHODS: Data from decompressive craniotomy after blunt force trauma that took place between December 2013 and June 2016 were collected in a multicenter chart. The primary outcomes were mortality and survival, as well as worse outcomes (defined as a Glasgow Outcome Scale [GOS] score <= 3) and better outcomes (GOS score >= 4). Secondary outcomes included 90-day survival rates in all patients with or without FFP transfusion, as well as length of hospital stay in patients with a better prognosis (GOS score >= 4). Univariate analysis, bivariate logistic regression, Spearman rank correlation, and Kaplan-Meier analysis were performed to account for the association between perioperative FFP transfusion and different outcomes. RESULTS: Bivariate logistic analysis showed that mortality and worse outcomes were correlated with FFP transfusion and Glasgow Coma Scale score (P < 0.05). Kaplan-Meier analysis suggested that mortality was statistically higher in the FFP transfusion groups compared with the no FFP transfusion groups, regardless of the severity of TBI (P < 0.05). The overall complications, acute respiratory distress syndrome, and pneumonia rate were significantly higher for patients receiving FFP transfusion (P < 0.05). CONCLUSIONS: Increased perioperative FFP infusion was independently associated with mortality or worse outcomes across a spectrum of surgical risk profiles.
