Use of resuscitative endovascular balloon occlusion of the aorta (REBOA) in a multidisciplinary approach for management of traumatic haemorrhagic shock: 10-year retrospective experience from a French level 1 trauma centre.

Background: The present study investigated an institutional multidisciplinary strategy for managing traumatic haemorrhagic shock by integrating the placement of REBOA (resuscitative endovascular balloon occlusion of the aorta) by anaesthesiologist-intensivists.

Methods: All severe trauma patients who received percutaneous REBOA placement between January 2013 and December 2022 in our level 1 trauma centre were retrospectively analysed. The data collected included the clinical context, indications and location of REBOA, durations of aortic occlusion (AO), choice of haemostatic procedures and surgical teams, and specific complications.

Results: In total, 38 trauma patients were included in the present study (mean age = 41 years [standard deviation = 21 years], 31 [82 %] were male, and median injury severity score was 62.5 [inter-quartile range (IQR) = 45-75]). REBOA was always placed by anaesthesiologist-intensivists, who comprised 68 % of the senior physicians (13/19) in our trauma team over the period. Twenty-eight AOs (74 %) were performed in zone 1 and 10 (26 %) in zone 3. Twelve patients (32 %) received REBOA upon circulatory arrest. Routes following REBOA placement comprised: computed tomography scan = 47 %, operating room = 34 %, angiography = 3 %, emergency room thoracotomy = 5 %, and prematurely died = 11 %. Duration of AO was 38 min (IQR = 32-44 min) in zone 1 and 78 min (IQR = 48-112 min) in zone 3. Mortality rate was 66 % (95 % CI 51-81 %) and higher in cases of AO in zone 1 (79 % versus 30 %, p = 0.018) or concomitant with circulatory arrest (92 % versus 54 %, p = 0.047). No ischemic limb needed an intervention and three endothelial injuries required delayed endovascular stenting.

Conclusions: Percutaneous REBOA placement by anaesthesiologist-intensivists included in the multidisciplinary management of traumatic haemorrhagic shock was associated with acceptable time of AO and local complications similar to those observed in other series.
