Introduction: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potential tool for the management of massive gastrointestinal bleeding (MGB). This study aims to describe the experience of the use of REBOA as adjunctive therapy in patients with MGB and to evaluate its effectiveness., Methods: Serial cases of patients with hemorrhagic shock secondary to MGB in whom REBOA was placed were collected. Patient demographics, bleeding severity, etiology, management, and clinical outcomes were recorded., Results: Between 2017 and 2020, five cases were analyzed. All patients had a severe gastrointestinal bleeding (Glasgow Blatchford Bleeding Score range 12-17; Clinical Rockal Score range 5-9). The etiologies of MGB were perforated gastric or duodenal ulcers, esophageal varices, and vascular lesions. Systolic blood pressure increased after REBOA placement and total occlusion time was 25-60 min. REBOA provided temporary hemorrhage control in all cases and allowed additional hemostatic maneuvers to be performed. Three patients survived more than 24 h. All patients died in index hospitalization. The main cause of death was related to hemorrhagic shock., Conclusions: Endovascular aortic occlusion can work as a bridge to further resuscitation and attempts at hemostasis in patients with MGB. REBOA provides hemodynamic support and may be used simultaneously with other hemostatic maneuvers, facilitating definitive hemorrhage control., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Background: Systolic blood pressure (SBP) is a potential indicator that could guide when to use a resuscitative endovascular balloon occlusion of the aorta (REBOA) in trauma patients with life-threatening injuries. This study aims to determine the optimal SBP threshold for REBOA placement by analyzing the association between SBP pre-REBOA and 24-hour mortality in severely injured hemodynamically unstable trauma patients., Methods: We performed a pooled analysis of the aortic balloon occlusion (ABO) trauma and AORTA registries. These databases record the details related to the use of REBOA and include data from 14 countries worldwide. We included patients who had suffered penetrating and/or blunt trauma. Patients who arrived at the hospital with a SBP pre-REBOA of 0 mm Hg and remained at 0 mm Hg after balloon inflation were excluded. We evaluated the impact that SBP pre-REBOA had on the probability of death in the first 24 hours., Results: A total of 1,107 patients underwent endovascular aortic occlusion, of these, 848 met inclusion criteria. The median age was 44 years (interquartile range [IQR], 27-59 years) and 643 (76%) were male. The median injury severity score was 34 (IQR, 25-45). The median SBP pre-REBOA was 65 mm Hg (IQR, 49-88 mm Hg). Mortality at 24 hours was reported in 279 (32%) patients. Math modeling shows that predicted probabilities of the primary outcome increased steadily in SBP pre-REBOA below 100 mm Hg. Multivariable mixed-effects analysis shows that when SBP pre-REBOA was lower than 60 mm Hg, the risk of death was more than 50% (relative risk, 1.5; 95% confidence interval, 1.17-1.92; p = 0.001)., Discussion: In patients who do not respond to initial resuscitation, the use of REBOA in SBPs between 60 mm Hg and 80 mm Hg may be a useful tool in resuscitation efforts before further decompensation or complete cardiovascular collapse. The findings from our study are clinically important as a first step in identifying candidates for REBOA., Level of Evidence: Prognostic and Epidemiological; Level IV., (Copyright © 2023 American Association for the Surgery of Trauma.)

Introduction: The effectiveness of resuscitative endovascular balloon occlusion of the aorta (REBOA) in controlling pelvic bleeding has been reported with increasing frequency during surgical management of placenta accreta spectrum (PAS). The deployment of REBOA may lead to significant variations in vital signs requiring special care by anesthesiology during surgery. These modifications of blood pressure by REBOA in PAS patients have not been accurately documented. We report the changes in blood pressure that occur when the aorta is occluded and then released in patients with PAS., Methodology: This prospective, observational study includes 10 patients with preoperative PAS suspicion who underwent prophylactic REBOA device insertion between April 2018 and October 2019. REBOA procedural-related data and blood pressure fluctuations under invasive monitoring before and after inflation and deflation were recorded in the operating room., Results: After prophylactic REBOA deployment in zone 3 of the aorta in PAS patients, we observed a transitory increase in blood pressure (median increase of 22.5 mmHg in SBP and 9.5 mmHg in DBP), which reached severe hypertension (SBP >160 mmHg) in 50% of patients. All patients presented a decrease in blood pressure after the removal of the aortic occlusion (median decrease of 23 mmHg in SBP and 10.5 mmHg in DBP), and 50% (five patients) required the administration of vasopressor drugs., Conclusion: Immediately after aortic occlusion is applied in zone 3 in PAS patients and after the occlusion is removed, significant hemodynamic changes occur, which often lead to therapeutic interventions.

Background: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a damage control tool with a potential role in the hemodynamic resuscitation of severely ill patients in the civilian pre-hospital setting. REBOA ensures blood flow to vital organs by early proximal control of the source of bleeding. However, there is no consensus on the use of REBOA in the pre-hospital setting. This article aims to perform a systematic review of the literature about the feasibility, survival, indications, complications, and potential candidates for civilian pre-hospital REBOA., Methods: A literature search was conducted using Medline, EMBASE, LILACS and Web of Science databases. Primary outcome variables included overall survival and feasibility. Secondary outcome variables included complications and potential candidates for endovascular occlusion., Results: The search identified 8 articles. Five studies described the use of REBOA in pre-hospital settings, reporting a total of 47 patients in whom the procedure was attempted. Pre-hospital REBOA was feasible in 68-100% of trauma patients and 100% of non-traumatic patients with cardiac arrest. Survival rates and complications varied widely. Pre-hospital REBOA requires a coordinated and integrated emergency health care system with a well-trained and equipped team. The remaining three studies performed a retrospective analysis identifying 784 potential REBOA candidates., Conclusions: Pre-hospital REBOA could be a feasible intervention for a significant portion of severely ill patients in the civilian setting. However, the evidence is limited. The impact of pre-hospital REBOA should be assessed in future studies., (© 2022. The Author(s).)

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is commonly used as an adjunct to resuscitation and bridge to definitive control of non-compressible torso hemorrhage in patients with hemorrhagic shock. It has also been performed for patients with neurogenic shock to support the central aortic pressure necessary for cerebral, coronary and spinal cord perfusion. Although volume replacement and vasopressors are the cornerstones of the management of neurogenic shock, we believe that a REBOA can be used as an adjunct in carefully selected cases to prevent prolonged hypotension and the risk of further anoxic spinal cord injury. This manuscript aims to propose a new damage control algorithmic approach to refractory neurogenic shock that includes the use of a REBOA in Zone 3. There are still unanswered questions on spinal cord perfusion and functional outcomes using a REBOA in Zone 3 in trauma patients with refractory neurogenic shock. However, we believe that its use in these case scenarios can be beneficial to the overall outcome of these patients., Competing Interests: Conflict of interest: The authors declare that they have no conflict of interest., (Copyright © 2021 Colombia Medica.)

Hemorrhagic shock and its complications are a major cause of death among trauma patients. The management of hemorrhagic shock using a damage control resuscitation strategy has been shown to decrease mortality and improve patient outcomes. One of the components of damage control resuscitation is hemostatic resuscitation, which involves the replacement of lost blood volume with components such as packed red blood cells, fresh frozen plasma, cryoprecipitate, and platelets in a 1:1:1:1 ratio. However, this is a strategy that is not applicable in many parts of Latin America and other low-and-middle-income countries throughout the world, where there is a lack of well-equipped blood banks and an insufficient availability of blood products. To overcome these barriers, we propose the use of cold fresh whole blood for hemostatic resuscitation in exsanguinating patients. Over 6 years of experience in Ecuador has shown that resuscitation with cold fresh whole blood has similar outcomes and a similar safety profile compared to resuscitation with hemocomponents. Whole blood confers many advantages over component therapy including, but not limited to the transfusion of blood with a physiologic ratio of components, ease of transport and transfusion, less volume of anticoagulants and additives transfused to the patient, and exposure to fewer donors. Whole blood is a tool with reemerging potential that can be implemented in civilian trauma centers with optimal results and less technical demand., (Copyright © 2020 Colombia Medica.)

Background: This study aimed to determine the critical threshold of systolic blood pressure (SBP) for aortic occlusion (AO) in severely injured patients with profound hemorrhagic shock., Methods: All adult patients (>15 years) undergoing AO via resuscitative endovascular balloon occlusion of the aorta (REBOA) or thoracotomy with aortic cross clamping (TACC) between 2014 and 2018 at level I trauma center were included. Patients who required cardiopulmonary resuscitation in the prehospital setting were excluded. A logistic regression analysis based on mechanism of injury, age, Injury Severity Score, REBOA/TACC, and SBP on admission was done., Results: A total of 107 patients underwent AO. In 57, TACC was performed, and in 50, REBOA was performed. Sixty patients who underwent AO developed traumatic cardiac arrest (TCA), and 47 did not (no TCA). Penetrating trauma was more prevalent in the TCA group (TCA, 90% vs. no TCA, 74%; p < 0.05) but did not modify 24-hour mortality (odds ratio, 0.51; 95% confidence interval, 0.13-2.00; p = 0.337). Overall, 24-hour mortality was 47% (50) and 52% (56) for 28-day mortality. When the SBP reached 60 mm Hg, the predicted mortality at 24 hours was more than 50% and a SBP lower than 70 mm Hg was also associated with an increased of probability of cardiac arrest., Conclusion: Systolic blood pressure of 60 mm Hg appears to be the optimal value upon which AO must be performed immediately to prevent the probability of death (>50%). However, values of SBP less than 70 mm Hg also increase the probability of cardiac arrest., Level of Evidence: Therapeutic study, level IV.
