Maternal hemodynamics during aortic occlusion with REBOA in patients with placenta accreta spectrum disorder.

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.

The Colombian Experience in Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA): The Progression From a Large Caliber to a Low-Profile Device at a Level I Trauma Center.

PURPOSE: Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) is now performed in many trauma centers, it is used at more than 250 hospitals in the United States and there is an increase rate of publications with the experience in these centers, but there is a gap of knowledge regarding the use of REBOA in Latin-America. This paper endeavors to describe the utilization of REBOA at a high level Latin-American Trauma Center and the transition from a large caliber to a low-profile device with the concomitant reduction in the groin access complications. METHODS: A prospective, observational, single-center study was conducted. We included all trauma patients who underwent REBOA. We recorded data from admission parameters, complications, and clinical outcomes. RESULTS: Fifty patients were included. Most of the REBOA catheters were inserted in the operating room [47 (94%)], and the arterial access was done by surgical cutdown [40 (80%)]. All the complications were associated with the catheter of 11 Fr Sheath used in 36 patients [n = 8/36 (22%) vs. n = 0/14 (0%); P = 0.05]. CONCLUSION: REBOA can be used safely in blunt or penetrating thoracic, abdominal, and pelvic trauma. The insertion of a 7 Fr Sheath was associated with lower complications, so its use should be preferred over larger calibers.

Resuscitative endovascular balloon of the aorta is feasible in penetrating chest trauma with major hemorrhage: Proposal of a new institutional deployment algorithm.

BACKGROUND: Resuscitative endovascular balloon occlusion of the aorta (REBOA) is an emerging option for hemorrhage control, but its use is limited in scenarios such as penetrating chest trauma. The aim of this study was to describe the use of REBOA as a resuscitative adjunct in these cases with major hemorrhage and to propose a new clinical management algorithm. METHODS: This was a prospective, observational study conducted at a single Level I trauma center in Colombia. We included all patients older than 14 years with severe trauma who underwent REBOA from January 2015 to December 2019. Patients received REBOA if they were in hemorrhagic shock and were unresponsive to resuscitation. RESULTS: A total of 56 patients underwent REBOA placement of which 37 had penetrating trauma and 23 had chest trauma. All patients were hemodynamically unstable upon arrival to the emergency department, with a median systolic blood pressure of 69 mm Hg (interquartile range [IQR], 57-90 mm Hg) and median Injury Severity Score was 25 (IQR, 25-41). All REBOAs were deployed and inflated in zone 1, median inflation time was 40 minutes (IQR, 26-55 minutes), and no adverse neurologic outcomes were observed. Fifteen patients had REBOA and a median sternotomy. Eleven patients had concomitant abdominal wounds. Overall mortality was 28.6%, and there was no significant difference between penetrating versus blunt trauma patients (21.6% vs. 42.1%, p = 0.11). The survival rate of thoracic injured patients was similar to the predicted survival (65.2% vs. 63.3%). CONCLUSION: Resuscitative endovascular balloon occlusion of the aorta can be used safely in penetrating chest trauma, and the implementation of a REBOA management algorithm is feasible with a well-trained multidisciplinary team. LEVEL OF EVIDENCE: Therapeutic, level V.

Damage control resuscitation: REBOA as the new fourth pillar.

Damage Control Resuscitation (DCR) seeks to combat metabolic decompensation of the severely injured trauma patient by battling on three major fronts: Permissive Hypotension, Hemostatic Resuscitation, and Damage Control Surgery (DCS). The aim of this article is to perform a review of the history of DCR/DCS and to propose a new paradigm that has emerged from the recent advancements in endovascular technology: The Resuscitative Balloon Occlusion of the Aorta (REBOA). Thanks to the advances in technology, a bridge has been created between Pre-hospital Management and the Control of Bleeding described in Stage I of DCS which is the inclusion and placement of a REBOA. We have been able to show that REBOA is not only a tool that aids in the control of hemorrhage, it is also a vital tool in the hemodynamic resuscitation of a severely injured blunt and/or penetrating trauma patient. That is why we propose a new paradigm "The Fourth Pillar": Permissive Hypotension, Hemostatic Resuscitation, Damage Control Surgery and REBOA.

La resucitación en control de daños busca combatir la descompensación metabólica del paciente severamente traumatizado mediante tres ejes: la hipotensión permisiva, la resucitación hemostática y la cirugía de control de daños. El objetivo de este artículo es hacer una revisión de la historia de la resucitación en control de daños y la cirugía de control de daños proponiendo un nuevo paradigma basado en los recientes avances de la tecnología endovascular. Un puente ha sido creado entre el manejo prehospitalario y el control del sangrado, descrito antes de la etapa I de la cirugía de control de daños, que es la inclusión y colocación de un REBOA. Esta es una herramienta adicional en el control de la hemorragia y de soporte en la resucitación hemodinámica de los pacientes con trauma severo de tipo cerrado y/o penetrante. Por lo que se propone un nuevo paradigma "El cuarto pilar": Hipotensión permisiva, resucitación hemostática, cirugía de control de daños y REBOA.

REBOA as a New Damage Control Component in Hemodynamically Unstable Noncompressible Torso Hemorrhage Patients.

Noncompressible torso hemorrhage is one of the leading causes of preventable death worldwide. An efficient and appropriate evaluation of the trauma patient with ongoing hemorrhage is essential to avoid the development of the lethal diamond (hypothermia, coagulopathy, hypocalcemia, and acidosis). Currently, the initial management strategies include permissive hypotension, hemostatic resuscitation, and damage control surgery. However, recent advances in technology have opened the doors to a wide variety of endovascular techniques that achieve these goals with minimal morbidity and limited access. An example of such advances has been the introduction of the Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), which has received great interest among trauma surgeons around the world due to its potential and versatility in areas such as trauma, gynecology & obstetrics and gastroenterology. This article aims to describe the experience earned in the use of REBOA in noncompressible torso hemorrhage patients. Our results show that REBOA can be used as a new component in the damage control resuscitation of the severely injured trauma patient. To this end, we propose two new deployment algorithms for hemodynamically unstable noncompressible torso hemorrhage patients: one for blunt and another for penetrating trauma. We acknowledge that REBOA has its limitations, which include a steep learning curve, its inherent cost and availability. Although to reach the best outcomes with this new technology, it must be used in the right way, by the right surgeon with the right training and to the right patient.

La hemorragia no compresible del torso es una de las principales causas de muerte prevenibles alrededor del mundo. Una evaluación eficiente y apropiada del paciente traumatizado con hemorragia activa es la esencia para evitar el desarrollo del rombo de la muerte (hipotermia, coagulopatía, hipocalcemia y acidosis). Actualmente, las estrategias de manejo inicial incluyen hipotensión permisiva, resucitación hemostática y cirugía de control de daños. Sin embargo, los recientes avances tecnológicos han abierto las puertas a una amplia variedad de técnicas endovasculares que logran esos objetivos con una morbilidad mínima y un acceso limitado. Un ejemplo de estos avances ha sido la introducción del balón de resucitación de oclusión aortica; REBOA ( Resuscitative Endovascular Balloon Occlusion of the Aorta , por sus sigla en inglés ), el cual, ha tenido gran provecho entre los cirujanos de trauma alrededor del mundo debido a su potencial y versatilidad en áreas como trauma, ginecología y obstetricia, y gastroenterología. El objetivo de este artículo es describir la experiencia lograda en el uso del REBOA en pacientes con hemorragia no compresible del torso. Nuestros resultados muestran que el REBOA puede usarse como un nuevo actor en la resucitación de control de daños del paciente con trauma severo, para este fin, nosotros proponemos dos nuevos algoritmos para el manejo de pacientes hemodinámicamente inestables: uno para trauma cerrado y otro para trauma penetrante. Se reconoce que el REBOA tiene sus limitaciones, las cuales incluye un periodo de aprendizaje, su costo inherente y la disponibilidad. A pesar de esto, para lograr los mejores resultados con esta nueva tecnología, el REBOA debe ser usado en el momento correcto, por el cirujano correcto con el entrenamiento y el paciente correcto.

Expanding indications and results for the use of resuscitative endovascular balloon occlusion of the aorta - REBOA. / Indicações e resultados para o uso expandido da oclusão ressuscitativa por balão endovascular da aorta - REBOA.

Currently, resuscitative endovascular balloon occlusion of the aorta (REBOA) is used in trauma surgery for controlling non-compressible torso hemorrhages, as a less invasive option and with fewer physiologic disturbances compared with an invasive emergent thoracotomy for aortic cross-clamping. This can allow improvements in hemodynamic parameters until definitive surgery is performed. REBOA is also used in trauma to prevent hemodynamic collapse in patients who are in severe hemorrhagic shock, as a method to maintain perfusion of the brain and heart while decreasing distal bleeding until hemorrhage control can take place. The major complications reported are acute kidney injury, lower leg amputations, and even death. As experience with REBOA in emergency surgery grows, new indications have been described in the literature. The aim of this study was to assess the expansion of the use of REBOA in other areas of medicine, as well as evaluating the current published series. We performed an online search of PubMed, Medline and SciELO with the term "REBOA" in the last five years, and the articles included were the 14 specifically describing the use of REBOA for non-traumatic conditions. The results suggest that the use of REBOA led to improved bleeding control and increased arterial pressure, reducing blood transfusion requirements and allowing patients to survive to definitive treatment of injuries. In conclusion, the expanded use of REBOA for non-traumatic emergencies appears to be effective. However, prospective studies and well-established protocols for specific indications should be developed to maximize patient outcomes.

A oclusão ressuscitativa por balão endovascular da aorta (REBOA) é utilizada para controlar hemorragias não compressíveis do tronco como uma opção menos invasiva e com menos distúrbios fisiológicos quando comparado à toracotomia de emergência com clampeamento da aorta. Isso permite a melhora dos parâmetros hemodinâmicos até que a cirurgia definitiva seja realizada. É utilizada no trauma como uma medida para prevenir o colapso hemodinâmico em pacientes que estão em choque hemorrágico grave, mantendo a perfusão do cérebro e do coração enquanto diminui o sangramento distal até que o controle da hemorragia possa ser realizado. As principais complicações relatadas são insuficiência renal aguda, amputações de membros inferiores e óbitos. O objetivo desse estudo foi avaliar a expansão do uso do REBOA em situações não traumáticas de outras áreas da medicina, assim como, avaliar os resultados obtidos até o momento. Uma pesquisa online do PubMed, Medline e SciELO foi realizada com o termo "REBOA" nos últimos cinco anos, e os artigos incluídos foram os 14 que descrevem especificamente o uso do REBOA para condições não traumáticas. Os resultados sugerem que o uso do REBOA levou a um melhor controle do sangramento e aumento da pressão arterial, reduzindo a necessidade de transfusão de sangue e permitindo que os pacientes sobrevivam ao tratamento definitivo das lesões. Concluindo, o uso expandido do REBOA para emergências não traumáticas parece ser eficaz, mas estudos prospectivos e protocolos bem estabelecidos devem ser desenvolvidos para maximizar os resultados.
