Ahmed N, Kuo YH. Resuscitative Endovascular Balloon Occlusion of The Aorta (REBOA) And Mortality in Hemorrhagic Shock Associated with Severe Pelvic Fracture: a National Data Analysis. BMC Emerg Med 2024; 24:104. [PMID: 38910235 PMCID: PMC11194952 DOI: 10.1186/s12873-024-01020-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Accepted: 06/07/2024] [Indexed: 06/25/2024] Open
Abstract
BACKGROUND The purpose of the study was to evaluate the mortality of patients who received Resuscitative Endovascular Balloon Occlusion of The Aorta (REBOA) in severe pelvic fracture with hemorrhagic shock. METHODS The American College of Surgeon Trauma Quality Improvement Program (ACS-TQIP) database for the calendar years 2017-2019 was accessed for the study. The study included all patients aged 15 years and older who sustained severe pelvic fractures, defined as an injury with an abbreviated injury scale (AIS) score of ≥ 3, and who presented with the lowest systolic blood pressure (SBP) of < 90 mmHg. Patients with severe brain injury were excluded from the study. Propensity score matching was used to compare the patients who received REBOA with similar characteristics to patients who did not receive REBOA. RESULTS Out of 3,186 patients who qualified for the study, 35(1.1%) patients received REBOA for an ongoing hemorrhagic shock with severe pelvic fracture. The propensity matching created 35 pairs of patients. The pair-matched analysis showed no significant differences between the group who received REBOA and the group that did not receive REBOA regarding patients' demography, injury severity, severity of pelvic fractures, lowest blood pressure at initial assessment and laparotomies. There was no significant difference found between REBOA versus no REBOA group in overall in-hospital mortality (34.3% vs. 28.6, P = 0.789). CONCLUSION Our study did not identify any mortality advantage in patients who received REBOA in hemorrhagic shock associated with severe pelvic fracture compared to a similar cohort of patients who did not receive REBOA. A larger sample size prospective study is needed to validate our results. CASE-CONTROL RETROSPECTIVE STUDY Level of Evidence IV.

Abstract
BACKGROUND Experimental work suggested that resuscitative Endovascular Balloon Occlusion of the aorta (REBOA) preserves cerebral circulation in animal models of traumatic brain injury. No clinical work has evaluated the role of REBOA in the presence of associated severe traumatic brain injury (TBI). We investigated the impacts of REBOA on neurological and survival outcomes. METHODS Propensity-score matched study, using the American College of Surgeons Trauma Quality Improvement Program database. Patients with severe TBI patients (Abbreviated Injury Scale ≥3) receiving REBOA within 4 h from arrival were matched with similar patients not receiving REBOA. Neurological matching included head AIS, pupils, and midline shift. Clinical outcomes were compared between the two groups. RESULTS 434 REBOA patients were matched with 859 patients without REBOA. Patients in the REBOA group had higher rates of in-hospital mortality (63.6 % vs 44.2 %, p < 0.001), severe sepsis (4.4 % vs 2.2 %, p = 0.029), acute kidney injury (10.1 % vs 6.6 %, p = 0.029), and withdrawal of life support (25.4 % vs 19.6 %, p = 0.020) despite of lower craniectomy/craniotomy rate (7.1 % vs 12.7 %, p < 0.002). CONCLUSION In patients with severe TBI, REBOA use is associated with an increased risk of in-hospital mortality, AKI, and infectious complications.

Propensity Score Analysis of Resuscitative Endovascular Balloon Occlusion of the Aorta: Zone-1 Versus Zone-3 Resuscitative Endovascular Balloon Occlusion of the Aorta Odds of Mortality. J Surg Res 2024; 295:660-665. [PMID: 38104529 DOI: 10.1016/j.jss.2023.11.049] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2023] [Revised: 10/07/2023] [Accepted: 11/12/2023] [Indexed: 12/19/2023]
Abstract
INTRODUCTION There are two zones for the placement of a Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) in trauma patients: above the mesenteric vessels (Zone-1) or below the renal arteries (Zone-3). Zone-1 REBOA diverts blood away from the visceral organs which leads to a systemic inflammatory response and reperfusion injury. We hypothesized that patients undergoing Zone-1 REBOA placement had a higher odds of mortality. METHODS The 2017-2019 Trauma Quality Improvement Program database was queried for patients undergoing either Zone-1 or Zone-3 REBOA. We excluded all patients with prehospital cardiac arrest. We compared Zone-1 versus Zone-3 REBOA using a 1:2 propensity-score model, matching for age, mechanism, sex, hypotension, tachycardia, blunt solid organ injury grade, pelvic fracture, and injuries to the aorta, iliac artery, iliac vein, and inferior vena cava. RESULTS We matched 130 Zone-1 REBOA patients to 260 Zone-3 REBOA patients. There were no statistically significant differences in the matched variables (P > 0.05). Compared to Zone-3 REBOA, patients with Zone-1 REBOA who survived ≥48 h had similar rates of acute kidney injury (18.6% versus 10.9%, P = 0.19). Zone-1 REBOA patients had a higher mortality rate (71.4% versus 48.8%, P = 0.002) and mortality odds ratio (OR) (OR 1.85, OR 1.18-2.89, P = 0.007). Zone-1 REBOA remained associated with a higher odds of mortality after controlling for traumatic brain injury and injury severity score (OR 1.86, OR 1.18-2.92, P = 0.007). CONCLUSIONS Compared to Zone-3, using a REBOA in Zone-1 is associated with higher odds of mortality. The use of REBOA Zone-1 deployment should be done with caution.

Complications associated with the use of resuscitative endovascular balloon occlusion of the aorta (REBOA): an updated review. Trauma Surg Acute Care Open 2024; 9:e001267. [PMID: 38347890 PMCID: PMC10860083 DOI: 10.1136/tsaco-2023-001267] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/02/2023] [Accepted: 12/22/2023] [Indexed: 02/15/2024] Open
Abstract
Resuscitative endovascular balloon occlusion of the aorta (REBOA) has become part of the arsenal to temporize patients in shock from severe hemorrhage. REBOA is used in trauma to prevent cardiovascular collapse by preserving heart and brain perfusion and minimizing distal hemorrhage until definitive hemorrhage control can be achieved. Significant side effects, including death, ischemia and reperfusion injuries, severe renal and lung damage, limb ischemia and amputations have all been reported. The aim of this article is to provide an update on complications related to REBOA. REBOA has emerged as a critical intervention for managing severe hemorrhagic shock, aiming to temporize patients and prevent cardiovascular collapse until definitive hemorrhage control can be achieved. However, this life-saving procedure is not without its challenges, with significant reported side effects. This review provides an updated overview of complications associated with REBOA. The most prevalent procedure-related complication is distal embolization and lower limb ischemia, with an incidence of 16% (range: 4-52.6%). Vascular and access site complications are also noteworthy, documented in studies with incidence rates varying from 1.2% to 11.1%. Conversely, bleeding-related complications exhibit lower documentation, with incidence rates ranging from 1.4% to 28.6%. Pseudoaneurysms are less likely, with rates ranging from 2% to 14%. A notable incidence of complications arises from lower limb compartment syndrome and lower limb amputation associated with the REBOA procedure. Systemic complications include acute kidney failure, consistently reported across various studies, with incidence rates ranging from 5.6% to 46%, representing one of the most frequently documented systemic complications. Infection and sepsis are also described, with rates ranging from 2% to 36%. Pulmonary-related complications, including acute respiratory distress syndrome and multisystem organ failure, occur in this population at rates ranging from 7.1% to 17.5%. This comprehensive overview underscores the diverse spectrum of complications associated with REBOA.

Non-compressible truncal and junctional hemorrhage: A retrospective analysis quantifying potential indications for advanced bleeding control in Dutch trauma centers. Injury 2024; 55:111183. [PMID: 37981519 DOI: 10.1016/j.injury.2023.111183] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 10/06/2023] [Accepted: 11/03/2023] [Indexed: 11/21/2023]
Abstract
BACKGROUND Truncal and junctional hemorrhage is the leading cause of potentially preventable deaths in trauma patients. To reduce this mortality, the application of advanced bleeding control techniques, such as resuscitative endovascular balloon occlusion of the aorta (REBOA), junctional tourniquets, Foley catheters, or hemostatic agents should be optimized. This study aimed to identify trauma patients with non-compressible truncal and junctional hemorrhage (NCTJH) who might benefit from advanced bleeding control techniques during initial trauma care. We hypothesized that there is a substantial cohort of Dutch trauma patients that can possibly benefit from advanced bleeding control techniques. METHODS Adult trauma patients with an Abbreviated Injury Scale ≥3 in the torso, neck, axilla, or groin region, who were presented between January 1st, 2014 and December 31st, 2018 to two Dutch level-1 trauma centers, were identified from the Dutch Trauma Registry. Potential indications for advanced bleeding control in patients with NCTJH were assessed by an expert panel of three trauma surgeons based on injury characteristics, vital signs, response to resuscitation, and received treatment. RESULTS In total, 1719 patients were identified of whom 249 (14.5 %) suffered from NCTJH. In 153 patients (60.6 %), hemorrhagic shock could have been mitigated or prevented with advanced bleeding control techniques. This group was younger and more heavily injured: median age of 40 versus 48 years and median ISS 33 versus 22 as compared to the entire cohort. The mortality rate in these patients was 31.8 %. On average, each of the included level-1 trauma centers treated an NCTJH patient every 24 days in whom a form of advanced bleeding control could have been beneficial. CONCLUSIONS More than half of included Dutch trauma patients with NCTJH may benefit from in-hospital application of advanced bleeding control techniques, such as REBOA, during initial trauma care. Widespread implementation of these techniques in the Dutch trauma system may contribute to reduction of mortality and morbidity from non-compressible truncal and junctional hemorrhage.

Medicine (Baltimore) 2023; 102:e34748. [PMID: 37653766 PMCID: PMC10470747 DOI: 10.1097/md.0000000000034748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 06/15/2023] [Accepted: 07/24/2023] [Indexed: 09/02/2023] Open
Abstract
Resuscitative endovascular balloon occlusion of the aorta (REBOA) is considered a key measure of treatment due to its use in stabilizing patients in shock through temporary inflow occlusion for noncompressible torso hemorrhage as well as its supportive role in myocardial and cerebral perfusion. Although its clinical efficacy in trauma has been widely recognized, concerns over related complications, such as vascular access and ischemia-reperfusion, are on the rise. This paper aims to investigate complications associated with REBOA and identify current and emerging prevention or mitigation strategies through a literature review based on human or animal data. Common complications associated with REBOA include ischemia/reperfusion injuries, vessel injuries, venous thromboembolism, and worsening proximal bleeding. REBOA treatment outcomes can be improved substantially with the help of precise selection of patients, better visualization tools, improvement in balloon catheters, blockage strategies, and medication intervention measures. Better understanding of REBOA-related complications and further research on the strategies to mitigate the occurrence of such complications will be of vital importance for the optimization of the clinical outcomes in patients.

Abstract
BACKGROUND Trauma related deaths remain a relevant public health problem, in particular in the younger male population. A significant number of these deaths occur prehospitally without transfer to a hospital. These patients, sometimes termed "the forgotten cohort", are usually not included in clinical registries, resulting in a lack of information about prehospitally trauma deaths. The aim of the present study was to compare patients who died prehospital with those who sustained life-threatening injuries in order to analyze and potentially improve prehospital strategies. METHODS This cohort study included all primary operations carried out by Switzerland's largest helicopter emergency medical service (HEMS) between January 1, 2011, and December 31, 2021. We included all adult trauma patients with life-threatening or fatal conditions. The outcome of this study is the vital status of the patient at the end of mission, i.e. fatal or life-threatening. Injury, rescue characteristics, and interventions of the forgotten trauma cohort, defined as patients with a fatal injury (NACA score of VII), were compared with life-threatening injuries (NACA score V and VI). RESULTS Of 110,331 HEMS missions, 5534 primary operations were finally analyzed, including 5191 (93.8%) life-threatening and 343 (6.2%) fatal injuries. More than two-thirds of patients (n = 3772, 68.2%) had a traumatic brain injury without a significant difference between the two groups (p > 0.05). Thoracic trauma (44.6% vs. 28.7%, p < 0.001) and abdominal trauma (22.2% vs. 16.1%, p = 0.004) were more frequent in fatal missions whereas pelvic trauma was similar between the two groups (13.4% vs. 12.9%, p = 0.788). Pneumothorax decompression rate (17.2% vs. 3.7%, p < 0.001) was higher in the forgotten cohort group and measures for bleeding control (15.2% vs. 42.7%, p < 0.001) and pelvic belt application (2.9% vs. 13.1% p < 0.001) were more common in the life-threating injury group. CONCLUSION Chest decompression rates and measures for early hemorrhage control are areas for potential improvement in prehospital care.

Abstract
ABSTRACT Objective: This study evaluated the feasibility of a combination of pelvic binder and rectal balloon compression in managing fatal venous hemorrhage in a canine model of pelvic fracture. Methods: Rectums from humans (rectal cancer patients), swine, and canines were retrieved to determine their elasticity by measuring their stress and strain. Canines were selected as the animal model in this study because their rectum demonstrated more reversible strain than swine rectum. Doppler ultrasound was used to assess the effect of rectal balloon volume on the blood flow of pelvic iliac blood vessels in three canines. A rectal balloon of 250 mL was chosen to control pelvic venous bleeding as it could provide a peak effect in reducing the blood flow of bilateral internal iliac veins. Then, the open-book pelvic fracture with fatal bleeding of both internal iliac veins animal model was built. The animals were divided into four groups after the modeled surgery to undergo no treatment, pelvic binder, rectal balloon compression, or a combination of pelvic binder and rectal balloon compression. The treatment efficacy was evaluated based on their survival time, survival rate, blood loss, bleeding rate, infusion rate, blood pH, lactate concentration, the stability of hemodynamics, blood loss, and fluid infusion volume. Results: Our results showed that after the reproducible injuries in both internal iliac veins, the combination of pelvic binder and rectal balloon compression was associated with the best survival rate and survival time compared with the other treatment groups. In addition, the combination of pelvic binder and rectal balloon compression exhibited more stable hemodynamics than the pelvic binder or rectal balloon compression treatment alone. Conclusions: This study demonstrated the potential feasibility of using pelvic binder combined with rectal balloon compression to manage the fatal venous bleeding in pelvic fractures.
