Concomitant Traumatic Brain Injury and Hemorrhagic Shock: Outcomes Using the Spanish Trauma ICU Registry (RETRAUCI)

Abstract

Background To compare the main outcomes of trauma patients with and without traumatic brain injury (TBI), hemorrhagic shock, and the combination of both using data from the Spanish trauma intensive care unit (ICU) registry (RETRAUCI). Methods Patients admitted to the participating ICUs from March 2015 to May 2019 were included in the study. The main outcomes were analyzed according to the presence of TBI, hemorrhagic shock, and/or both. Comparison of groups with quantitative variables was performed using the Kruskal-Wallis test, and differences between groups with categorical variables were compared using the Chi-square test or Fisher’s exact test as appropriate. A P value <.05 was considered significant. Results Overall, 310 patients (3.98%) were presented with TBI and hemorrhagic shock. Patients with TBI and hemorrhagic shock received more red blood cell (RBC) concentrates, fresh frozen plasma (FFP), a higher ratio FFP/RBC, and had a higher incidence of trauma-induced coagulopathy (60%) ( P < .001). These patients had higher mortality ( P < .001). Intracranial hypertension was the leading cause of death (50.4%). Conclusions Concomitant TBI and hemorrhagic shock occur in nearly 4% of trauma ICU patients. These patients required a higher amount of RBC concentrates and FFP and had an increased mortality.
