Objective: Patients with moderate to severe traumatic brain injury (TBI) with or without relevant concomitant injuries are usually treated on intensive care units (ICUs) with invasive ventilation. Consequently, these patients are at increased risk of lung failure, potentially requiring extracorporeal membrane oxygenation (ECMO). The aim of this work is to provide an overview of ECMO treatment in TBI based upon data captured into the German TraumaRegistry (TR-DGU).
Methods: A retrospective multi-center cohort analysis of patients registered in into the TR-DGU was conducted. Adult patients with relevant TBI (AIS Head ≥3) who had been treated in German, Austrian, and Swiss level 1 or 2 trauma centers between 2015 and 2019 were included. Multivariable logistic regression analysis was performed to identify early risk factors associated with need for ECMO treatment.
Results: 16,513 patients fulfilled the inclusion criteria and were analyzed. The overall rate of ECMO treatment was 0.8% (134 patients) with the highest rate of 1.03% among16-59 year old patients. Patients on ECMO had an overall hospital mortality rate of 38.1% (51/134 patients) while 12.5% (2055/16.379patients) of TBI patients without ECMO died. Risk factors for ECMO were male gender (p=0.029), AISChest 4 (p=0.048), AISChest 5 (p=0.008) and packed red blood cell (pRBC) transfusion (1-9 pRBC (p<0.001), ≥ 10 pRBC (p=0.002)).
Conclusion: ECMO therapy is a key component to the treatment of moderate-to-severe TBI combined with severe chest trauma and pulmonary failure. Even though associated with higher in-hospital mortality, the majority of ECMO patients is surviving. Severe chest trauma and pRBC transfusion are potential early predictors for the need of ECMO in the further clinical course of TBI patients.
