Outcomes in Trauma Patients Undergoing Venovenous Extracorporeal Membrane Oxygenation for Adult Respiratory Distress Syndrome
Abstract Background: Use of venovenous extracorporeal membrane oxygenation (VV ECMO) remains controversial in trauma patients with adult respiratory distress syndrome (ARDS). Here, we aimed to investigate its therapeutic benefits and the factors affecting patient outcomes.Methods: From 2017–2019, 21/1938 trauma patients (median age: 47 years; 20 men) at a level I trauma center received VV ECMO for post-traumatic ARDS. Demographic, injury-specific, ECMO, and outcome data were prospectively collected and retrospectively reviewed to analyze the factors affecting hospital mortality and ECMO results.Results: Nineteen patients (90.5%) were successfully weaned off ECMO; 16 patients (76.2%) survived to discharge. In the univariate analysis, there was a significant difference in survival between the groups with a Trauma and Injury Severity Score (TRISS) ≥0.5 and TRISS <0.5 (p=0.05). The area under the receiver operating characteristic curve (AUC) of both TRISS and Respiratory Extracorporeal Membrane Oxygenation Survival Prediction (RESP) scores in death was 0.78. In those who failed ECMO weaning, the AUCs of TRISS and RESP scores were 0.90 and 0.80, respectively.Conclusions: In patients with ARDS caused by severe trauma and supported by VV ECMO, survival is associated with TRISS; TRISS and RESP scores may be predictive of mortality and failure of ECMO weaning.
