- BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is becoming a standardized adjunct for the management in patients with severe non-compressible torso hemorrhage (NCTH). Although guidelines have been developed to help with the best indications for REBOA utilization, no studies have addressed the significance of change in systolic blood pressure (ΔSBP) after REBOA insufflation. We hypothesized that ΔSBP would predict mortality in patients with NCTH and have utility as a surrogate marker for hemorrhage status.STUDY DESIGN: This was an international, multicenter retrospective review of all patients managed with REBOA from the ABOTrauma Registry and the AORTA database. ΔSBP was defined as the difference between pre- and post-REBOA insertion SBP. Based on post-insertion SBP, patient hemorrhage status was categorized as responder or non-responder. A non-responder was defined as a hypotensive patient with systolic blood pressure (SBP) < 90 mmHg after REBOA placement with full aortic occlusion. Significance was set at P < 0.05.RESULTS: A total of 524 patients with NCTH were included. Most (74%) were male, 77% blunt injured with a median (IQR) age of 40 (27 - 58) years and ISS 34 (25 - 45). Overall mortality was 51.0%. 20% of patients were classified as non-responders. Demographic and injury descriptors did not differ between groups. Mortality was significantly higher in non-responders vs responders (64% vs 46%, respectively; P = 0.001). Non-responders had lower median pre-insertion SBP (50mmHg vs 67mmHg; P < 0.001) and lower ΔSBP (20mmHg vs 48mmHg; P < 0.001).CONCLUSION: REBOA non-responders present and remain persistently hypotensive and are more likely to die than responders, indicating a potential direct correlation between ΔSBP as a surrogate marker of hemorrhage volume status and mortality. Future prospective studies will need to further elucidate the impact of Damage Control Resuscitation efforts on ΔSBP and mortality.

Prehospital Mortality Due to Hemorrhagic Shock Remains High and Unchanged : A Summary of Current Civilian EMS Practices and New Military Changes
- 2021

In: Shock. - : Lippincott Williams & Wilkins. - 1073-2322 .- 1540-0514. ; 56:1S, s. 3-8

Journal article (peer-reviewed)abstract
- Mortality secondary to trauma related hemorrhagic shock has not improved for several decades. Underlying the stall in progress is the conundrum of effective pre-hospital interventions for hemorrhage control. As we know, neither pressing hard on the gas nor "Stay and play" have changed mortality over the last 20 years. For this reason, when dealing with effective changes that will improve severe hemorrhage mortality outcomes, there is a need for the creation of a hybrid pre-hospital model.Improvements in mortality outcomes for patients with severe hemorrhage based on evidence for common civilian prehospital procedures such as in-field intubation and immediate fluid resuscitation with crystalloid solution is weak at best. The use of tourniquets, once considered too risky to use, however, has risen dramatically in large part due success seen during their use in the military. Their use in the civilian setting shows promising results. Recently updated military Advanced Resuscitative Care (ARC) guidelines propose the use of prehospital whole blood transfusion as well as in-field use of Zone 1 Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA). Several case studies from Europe suggest these strategies are feasible for use in the civilian population, but could they be implemented in the U.S.?

To Ultrasound or not to Ultrasound : A REBOA Femoral Access Analysis from the ABOTrauma and AORTA Registries
- 2020
-
In: Journal of endovascular resuscitation and trauma management. - Örebro : Society of Endovascular Resuscitation and Trauma Management in cooperation with Örebro University Hospital. - 2002-7567. ; 4:2, s. 80-87

Journal article (peer-reviewed)abstract
- Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is becoming a standardized adjunct in the management of non-compressible hemorrhage. Ultrasound (US)-guided femoral access has been taught as the best practice for femoral artery cannulation. However, there is a lack of evidence to support its use in patients in extremis with severe hemorrhage. We hypothesize that no differences in outcome will exist between US-guided and to blind percutaneous or cutdown access methods.Methods: This was an international, multicenter retrospective review of all patients managed with REBOA from the ABOTrauma Registry and the AORTA database. REBOA characteristics and outcomes were compared among puncture access methods. Significance was set at P < 0.05.Results: The cohort included 523 patients, primarily male (74%), blunt injured (77%), with median age 40 (27-58), and an Injury Severity Score of 34 (25-45). Percutaneous using external landmarks/palpation was the most common femoral puncture method (53%) used followed by US-guided (27.9%). There was no significant difference in overall complication rates (37.4% vs 34.9%; P = 0.615) or mortality (47.8% vs 50.3%; P = 0.599) between percutaneous and US-guided methods; however, access by cutdown was significantly associated with emergency department (ED) mortality (P = 0.004), 24 hour mortality (P = 0.002), and in-hospital mortality (P = 0.007).Conclusions: In patients with severe hemorrhage in need of REBOA placement, the percutaneous approach using anatomic landmarks and palpation, when compared with US-guided femoral access, was used more frequently without an increase in complications, access attempts, or mortality.

Time to Hemorrhage Control in a Hybrid ER System : Is It Time to Change?
- 2021
-
In: Shock. - : Lippincott Williams & Wilkins. - 1073-2322 .- 1540-0514. ; 56:1S, s. 16-21

Journal article (peer-reviewed)abstract
- Time to hemorrhage control is critical, as mortality in patients with severe hemorrhage that arrive to trauma centers with sign of life remains over 40%. Prompt identification and management of severe hemorrhage is paramount to reducing mortality. In traditional US trauma systems, the early hospital course of a severely hemorrhaging patient typically proceeds from the trauma resuscitation bay to the operating room or angiography suite with a potential stop for radiological imaging. This protracted journey can prove fatal as it consumes valuable minutes. In contrast to the current US system is a newly developed and increasingly adopted system in Japan called the hybrid emergency room system (HERS). The hybrid ER is equipped to allow resuscitation, imaging, and damage control intervention to occur in the ER without the need to transport the patient to a subsequent destination. The HERS is relatively new and remains restricted to a small number of institutions, limiting the ability to robustly examine impact(s) on patient outcomes. Even if proven to yield superior outcomes, there are significant obstacles to adopting the HERS in the US. Challenges such as the high cost of building and implementing a HER system, return on investment, and the significant differences between the US and Japan in terms of physician training, trauma center, and reimbursement schemes may render the hybrid ER system to be unfeasible in most current trauma centers. Barriers aside, the Japanese hybrid ER system remains the most novel recent advancement in the quest to reduce potentially preventable mortality from hemorrhage.
