Establishing a regional pediatric trauma preventable/potentially preventable death rate

Development and Validation of a Bayesian Network Predicting Intubation Following Hospital Arrival Among Injured Children

BACKGROUND

Inadequate airway management can contribute to preventable trauma deaths. Current machine learning tools for predicting intubation in trauma are limited to adult populations and include predictors not readily available at the time of patient arrival. We developed a Bayesian network to predict intubation in injured children and adolescents using observable data available upon or immediately after patient arrival.

METHODS

We obtained patient demographic, injury, resuscitation, and transportation characteristics from trauma registries from four American College of Surgeons-verified level 1 pediatric trauma centers from January 2010 through December 2021. We trained and validated a Bayesian network to predict emergent intubation after pediatric injury. We evaluated model performance using the area under the receiver operating and calibration curves.

RESULTS

The final model, TITAN (Timing of Intubation in Trauma Analysis Network), incorporated five factors: Glasgow Coma Scale, mechanism of injury, injury type (e.g., penetrating, blunt), systolic blood pressure, and age. The model achieved an area under the receiver operating characteristic curve of 0.83 (95% CI 0.80, 0.85) and had a calibration curve slope of 0.98 (95% CI 0.67, 1.29). TITAN had high specificity (98%), negative predictive value (97%), and accuracy (96%) at a binary probability threshold of 22.6%.

CONCLUSION

The TITAN Bayesian network predicts the risk of intubation in pediatric trauma patients using five factors that are observable early in trauma resuscitation. Prospective validation of the model performance with patient outcomes is needed to assess real-life application benefits and risks.

Principles and Practice in Pediatric Vascular Trauma: Part 2: Fundamental Vascular Principles, Pediatric Nuance, and Follow-up Strategies

As of 2020, penetrating injuries became the leading cause of death among children and adolescents ages 1-19 in the United States. For those patients who survive and receive advanced medical care, vascular injuries are a significant cause of morbidity and trigger notable trauma team angst. Moreover, penetrating injuries can lead to life-threatening hemorrhage and/or limb-threatening ischemia if not addressed promptly. Vascular injury management demands timely and unique expertise, particularly for pediatric patients. In part 1 of this review, we discussed the scope and extent of the epidemic of traumatic vascular injuries in pediatric patients, reviewed current evidence and outcomes, discussed various challenges and advantages of a myriad of existing team structures, and outlined potential outcome targets and solutions. However, in order to optimize care for pediatric vascular trauma, we must also understand the fundamental best practice principles, surgical options and approaches, medical management, and recommendations for ongoing, outpatient follow-up. In part 2, we will address the best evidence, combined with expert consensus, regarding strategies for diagnosing, managing, and ongoing follow-up of vascular trauma, with particular focus on the nuances that define the unique approaches to pediatric patients.

Benchmarking Pediatric Trauma Care in Mixed Trauma Centers: Adult Risk-Adjusted Mortality Is Not a Reliable Indicator of Pediatric Outcomes

BACKGROUND

Trauma center benchmarking has become standard practice for assessing quality. The American College of Surgeons adult trauma center verification standards do not specifically require participation in a pediatric-specific benchmarking program. Centers that treat adults and children may therefore rely solely on adult benchmarking metrics as a surrogate for pediatric quality. This study assessed discordance between adult and pediatric mortality within mixed trauma centers to determine the need to independently report pediatric-specific quality metrics.

STUDY DESIGN

A cohort of trauma centers (n = 493, including 347 adult-only, 44 pediatric-only, and 102 mixed) that participated in the American College of Surgeons TQIP in 2017 to 2018 was analyzed. Center-specific observed-to-expected mortality estimates were calculated using TQIP adult inclusion criteria for 449 centers treating adults (16 to 65 years) and using TQIP pediatric inclusion criteria for 146 centers treating children (0 to 15 years). We then correlated risk-adjusted mortality estimates for pediatric and adult patients within mixed centers and evaluated concordance of their outlier status between adults and children.

RESULTS

The cohort included 394,075 adults and 97,698 children. Unadjusted mortality was 6.1% in adults and 1.2% in children. Mortality estimates had only moderate correlation ( r = 0.41) between adult and pediatric cohorts within individual mixed centers. Mortality outlier status for adult and pediatric cohorts was discordant in 31% (32 of 102) of mixed centers (weighted Kappa statistic 0.06 [-0.11 to 0.22]), with 78% (23 of 32) of discordant centers having higher odds of mortality for children than for adults (6 centers with average adult mortality and high pediatric mortality and 17 centers with low adult mortality and average pediatric mortality, p < 0.01).

CONCLUSIONS

Adult mortality is not a reliable surrogate for pediatric mortality in mixed trauma centers. Incorporation of pediatric-specific benchmarks should be required for centers that admit children.

Commentary on gaps in prehospital trauma care: education and bioengineering innovations to improve outcomes in hemorrhage and traumatic brain injury

Hemorrhage remains the leading cause of preventable death on the battlefield and the civilian arena. Many of these deaths occur in the prehospital setting. Traumatic brain injury also represents a major source of early mortality and morbidity in military and civilian settings. The inaugural HERETIC (HEmostatic REsuscitation and Trauma Induced Coagulopathy) Symposium convened a multidisciplinary panel of experts in prehospital trauma care to discuss what education and bioengineering advancements in the prehospital space are necessary to improve outcomes in hemorrhagic shock and traumatic brain injury. The panel identified several promising technological breakthroughs, including field point-of-care diagnostics for hemorrhage and brain injury and unique hemorrhage control options for non-compressible torso hemorrhage. Many of these technologies exist but require further advancement to be feasibly and reliably deployed in a prehospital or combat environment. The panel discussed shifting educational and training paradigms to clinical immersion experiences, particularly for prehospital clinicians. The panel discussed an important balance between pushing traditionally hospital-based interventions into the field and developing novel intervention options specifically for the prehospital environment. Advancing prehospital diagnostics may be important not only to allow more targeted applications of therapeutic options, but also to identify patients with less urgent injuries that may not need more advanced diagnostics, interventions, or transfer to a higher level of care in resource-constrained environments. Academia and industry should partner and prioritize some of the promising advances identified with a goal to prepare them for clinical field deployment to optimize the care of patients near the point of injury.

Survival of a hemodynamically unstable pediatric liver trauma patient with aortic balloon occlusion catheter during air transport: A case report

Background

The utility of resuscitative endovascular balloon occlusion of the aorta (REBOA) in children remains unclear.

Case Presentation

An 11-year-old patient with liver trauma with massive extravasation was transported to a local hospital, where an emergency trauma surgery was unavailable. Following the placement of REBOA as a bridge to hemostasis, she was transferred to our hospital by a firefighting helicopter with balloon occlusion. Immediately, she underwent damage control laparotomy and transcatheter arterial embolization. She was subsequently discharged from the hospital 6 months after the accident without complications.

Conclusion

REBOA as a bridge to hemostasis may be useful for pediatric patients.

Hypofibrinogenemia following injury in 186 children and adolescents: identification of the phenotype, current outcomes, and potential for intervention

Objectives

Recent studies evaluating fibrinogen replacement in trauma, along with newly available fibrinogen-based products, has led to an increase in debate on where products such as cryoprecipitate belong in our resuscitation strategies. We set out to define the phenotype and outcomes of those with hypofibrinogenemia and evaluate whether fibrinogen replacement should have a role in the initial administration of massive transfusion.

Methods

All patients <18 years of age presenting to our trauma center 11/17-4/21 were reviewed. We then evaluated all patients who received emergency-release and massive transfusion protocol (MTP) products. Patients were defined as hypofibrinogenemic (HYPOFIB) if admission fibrinogen <150 or rapid thrombelastography (r-TEG) angle <60 degrees. Our analysis sought to define risk factors for presenting with HYPOFIB, the impact on outcomes, and whether early replacement improved mortality.

Results

4169 patients were entered into the trauma registry, with 926 level 1 trauma activations, of which 186 patients received emergency-release blood products during this time; 1%, 3%, and 10% were HYPOFIB, respectively. Of the 186 patients of interest, 18 were HYPOFIB and 168 were non-HYPOFIB. The HYPOFIB patients were significantly younger, had lower field and arrival Glasgow Coma Scale, had higher head Abbreviated Injury Scale, arrived with worse global coagulopathy, and died from brain injury. Non-HYPOFIB patients were more likely to have (+)focused assessment for the sonography of trauma on arrival, sustained severe abdominal injuries, and die from hemorrhage. 12% of patients who received early cryoprecipitate (0-2 hours) had higher mortality by univariate analysis (55% vs 31%, p=0.045), but no difference on multivariate analysis (OR 0.36, 95% CI 0.07 to 1.81, p=0.221). Those receiving early cryoprecipitate who survived after pediatric intensive care unit (PICU) admission had lower PICU fibrinogen and r-TEG alpha-angle values.

Conclusion

In pediatric trauma, patients with hypofibrinogenemia on admission are most likely younger and to have sustained severe brain injury, with an associated mortality of over 80%. Given the absence of bleeding-related deaths in HYPOFIB patients, this study does not provide evidence for the empiric use of cryoprecipitate in the initial administration of a massive transfusion protocol.

Child traumatic physical abuse rates and comparisons during the COVID-19 pandemic: Retrospective paediatric single institution review in Texas

AIM

The COVID-19 pandemic drastically altered human behaviour and socialisation and may have created an environment that could lead to increased incidence of domestic abuse and non-accidental trauma, or child physical abuse (CPA). Initial reports about the effect of the COVID-19 pandemic on the rates of CPA have been mixed. The purpose of this study is to describe the effects of COVID-19 on rates of CPA in a large metropolitan paediatric hospital and level I paediatric trauma centre.

METHODS

We identified and compared all CPA admissions under 18 years from May 2019 to February 2020 and considered that to be the pre-COVID time frame. The ensuing 12-month period of March 2020 to February 2021 was considered to be the intra-COVID time frame.

RESULTS

There were 49 (0.32%) unique CPA patients pre-COVID and 83 (0.85%) unique CPA patients intra-COVID (P < 0.001) with lower total admissions for any reason during the intra-COVID time frame. Monthly CPA cases were increased (P < 0.03) during the intra-COVID time period (mean 6.9, 95% confidence interval: 5.8-12.7) compared to the pre-COVID time period (mean 4.9, 95% confidence interval: 3.3-8.2).

CONCLUSION

During the COVID-19 pandemic, there were decreased overall hospital admissions in the period of mandated shutdowns and isolation. However, we saw an increased rate of CPA admissions compared to the time period prior to the pandemic. Knowledge of such data, trends and circumstances will help keep health-care providers alert and vigilant in identifying children at risk for maltreatment, and may impact child abuse protocols and guidelines.

Balanced resuscitation: application to the paediatric trauma population

PURPOSE OF REVIEW

Trauma is the leading cause of death in children over 5 years old. Early mortality is associated with trauma-induced coagulopathy (TIC), with balanced resuscitation potentially mitigating the effects of TIC. We review TIC, balanced resuscitation and the best evidence for crystalloid fluid versus early blood products, massive transfusion protocol (MTP) and the optimal ratio for blood products.

RECENT FINDINGS

Crystalloid fluids have been associated with adverse events in paediatric trauma patients. However, the best way to implement early blood products remains unclear; MTP has only shown improved time to blood products without clear clinical improvement. The indications to start blood products are also currently under investigation with several scoring systems and clinical indications being studied. Current studies on the blood product ratio suggest a 1 : 1 ratio for plasma:pRBC is likely ideal, but prospective studies are needed to further support its use.

SUMMARY

Balanced resuscitation strategies of minimal crystalloid use and early administration of blood products are associated with improved morbidity in paediatric trauma patients but unclear mortality benefit. Current evidence suggests that the utilization of MTPs with 1 : 1 plasma:pRBC ratio may improve morbidity, but more research is needed.

Short: Prediction of fetal blood oxygen content in response to partial occlusion of maternal aorta

Acute hemorrhage in pregnancy may lead to maternal and/or fetal morbidity or mortality. In emergency medicine, blockage of the aorta via an inflatable endovascular balloon, technically referred to Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA), is used to manage hemorrhage. However, the application of REBOA in pregnancy needs to strike a balance between two competing objectives of limiting maternal blood loss and ensuring fetal wellness, for which one would need to predict the impact of regulated blood pressure on fetal wellness. To address this problem, we propose an efficient machine learning-based method to predict the temporal impact of the distal Mean Arterial Blood Pressure (dMAP) controlled by the REBOA on the oxygen content in the fetal blood. Evaluation of the algorithm on data collected from in-vivo experiments from pregnant ewe animal models exhibits mean absolute error of 0.61, 1.09, 1.42, 1.70 mmHg, and coefficient of determination of 0.95, 0.86, 0.76, 0.64 for prediction of partial pressure of oxygen in fetal arterial blood, a key predictor of fetal wellness, in 2.5, 5, 7.5, 10-minute prediction horizons, respectively.

Failure-to-rescue and mortality after emergent pediatric trauma laparotomy: How are the children doing?

INTRODUCTION

Emergent trauma laparotomy is associated with mortality rates of up to 40%. There is a paucity of data on the outcomes of emergent trauma laparotomies performed in the pediatric population. The aim of our study was to describe the outcomes, including mortality and FTR, among pediatric trauma patients undergoing emergent laparotomy and identify factors associated with failure-to-rescue (FTR).

METHODS

We performed a one-year (2017) retrospective cohort analysis of the American College of Surgeons Trauma Quality Improvement Program dataset. All pediatric trauma patients (age <18 years) who underwent emergent laparotomy (laparotomy performed within 2 h of admission) were included. Outcome measures were major in-hospital complications, overall mortality, and failure-to-rescue (death after in-hospital major complication). Multivariate regression analysis was performed to identify factors independently associated with failure-to-rescue.

RESULTS

Among 120,553 pediatric trauma patients, 462 underwent emergent laparotomy. Mean age was 14±4 years, 76% of patients were male, 49% were White, and 50% had a penetrating mechanism of injury. Median ISS was 25 [13-36], Abdomen AIS was 3 [2-4], Chest AIS was 2 [1-3], and Head AIS was 2 [0-5]. The median time in ED was 33 [18-69] minutes, and median time to surgery was 49 [33-77] minutes. The most common operative procedures performed were splenectomy (26%), hepatorrhaphy (17%), enterectomy (14%), gastrorrhaphy (14%), and diaphragmatic repair (14%). Only 22% of patients were treated at an ACS Pediatric Level I trauma center. The most common major in-hospital complications were cardiac (9%), followed by infectious (7%) and respiratory (5%). Overall mortality was 21%, and mortality among those presenting with hypotension was 31%. Among those who developed in-hospital major complications, the failure-to-rescue rate was 31%. On multivariate analysis, age younger than 8 years, concomitant severe head injury, and receiving packed red blood cell transfusion within the first 24 h were independently associated with failure-to-rescue.

CONCLUSIONS

Our results show that emergent trauma laparotomies performed in the pediatric population are associated with high morbidity, mortality, and failure-to-rescue rates. Quality improvement programs may use our findings to improve patient outcomes, by increasing focus on avoiding hospital complications, and further refinement of resuscitation protocols.

Prehospital Tranexamic Acid in Major Pediatric Trauma Within a Physician-Led Emergency Medical Services System: A Multicenter Retrospective Study

OBJECTIVES

Describe prehospital tranexamic acid (TXA) use and appropriateness within a major trauma pediatric population, and identify the factors associated with its use.

DESIGN

Multicenter, retrospective study, 2014-2020.

SETTING

Data were extracted from a multicenter French trauma registry including nine trauma centers within a physician-led prehospital emergency medical services (EMS) system.

PATIENTS

Patients less than 18 years old were included. Those who did not receive prehospital intervention by a mobile medical team and those with missing data on TXA administration were excluded.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

Nine-hundred thirty-four patients (median [interquartile range] age: 14 yr [9-16 yr]) were included, and 68.6% n = 639) were male. Most patients were involved in a road collision (70.2%, n = 656) and suffered a blunt trauma (96.5%; n = 900). Patients receiving TXA (36.6%; n = 342) were older (15 [13-17] vs 12 yr [6-16 yr]) compared with those who did not. Patient severity was higher in the TXA group (Injury Severity Score 14 [9-25] vs 6 [2-13]; p < 0.001). The median dosage was 16 mg/kg (13-19 mg/kg). TXA administration was found in 51.8% cases ( n = 256) among patients with criteria for appropriate use. Conversely, 32.4% of patients ( n = 11) with an isolated severe traumatic brain injury (TBI) also received TXA. Age (odds ratio [OR], 1.2; 95% CI, 1.1-1.2), A and B prehospital severity grade (OR, 7.1; 95% CI, 4.1-12.3 and OR, 4.5; 95% CI, 2.9-6.9 respectively), and year of inclusion (OR, 1.2; 95% CI, 1.1-1.3) were associated with prehospital TXA administration.

CONCLUSIONS

In our physician-led prehospital EMS system, TXA is used in a third of severely injured children despite the lack of high-level of evidence. Only half of the population with greater than or equal to one criteria for appropriate TXA use received it. Conversely, TXA was administered in a third of isolated severe TBI. Further research is warranted to clarify TXA indications and to evaluate its impact on mortality and its safety profile to oversee its prescription.

Balloons for kids: Anatomic candidacy and optimal catheter size for pediatric resuscitative endovascular balloon occlusion of the aorta

BACKGROUND

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a potential adjunct in pediatric trauma patients with noncompressible truncal and pelvic hemorrhage; however, there are little data evaluating the anatomic considerations of REBOA in children. We evaluated the vascular dimensions and anatomic limitations of using REBOA in children.

METHODS

Computed tomography scans of pediatric patients performed between February 2016 and October 2019 were retrospectively reviewed by two investigators. Vascular measurements included diameters of aorta zones I and III, common iliac arteries, external iliac arteries, and common femoral arteries (CFAs), and distances between access site (CFA) and aorta zones I and III. Measurements were grouped within Broselow categories, based upon patient height. Interrater reliability for measurements was determined using intraclass correlation coefficients. Vascular dimensions were correlated with the patient's height, weight, and body mass index using linear regression analysis.

RESULTS

A total of 557 computed tomography scans met the inclusion criteria and were reviewed. Measurements of vessel diameter and distance from the CFA to aorta zones I and III were determined and grouped by Broselow category. Patient age ranged from 0 to 18 years, with a male to female ratio of 1:1. Overall interrater reliability of vessel measurements was good (average intraclass correlation coefficient, 0.90). Vessel diameter had greatest correlation with height (R2 = 0.665, aorta zone I; R2 = 0.611, aorta zone III) and poorly correlated with body mass index (R2 = 0.318 and R2 = 0.290, respectively).

CONCLUSION

This study represents the largest compilation of REBOA-related pediatric vessel diameter measurements and the first to provide data on distance between access site and balloon deployment zones. Based on our findings, the 7-Fr REBOA catheter would be appropriate for the Black, Green, and Orange Broselow categories, and a 4-Fr REBOA catheter would be warranted for Yellow, White, and Blue Broselow categories.

Preventable death in trauma: A systematic review on definition and classification

PURPOSE

Trauma-related preventable death (TRPD) has been used to assess the management and quality of trauma care worldwide. However, due to differences in terminology and application, the definition of TRPD lacks validity. The aim of this systematic review is to present an overview of current literature and establish a designated definition of TRPD to improve the assessment of quality of trauma care.

METHODS

A search was conducted in PubMed, Embase, the Cochrane Library and the Web of Science Core Collection. Including studies regarding TRPD, published between January 1, 1990, and April 6, 2021. Studies were assessed on the use of a definition of TRPD, injury severity scoring tool and panel review.

RESULTS

In total, 3,614 articles were identified, 68 were selected for analysis. The definition of TRPD was divided in four categories: I. Clinical definition based on panel review or expert opinion (TRPD, trauma-related potentially preventable death, trauma-related non-preventable death), II. An algorithm (injury severity score (ISS), trauma and injury severity score (TRISS), probability of survival (Ps)), III. Clinical definition completed with an algorithm, IV. Other. Almost 85% of the articles used a clinical definition in some extend; solely clinical up to an additional algorithm. A total of 27 studies used injury severity scoring tools of which the ISS and TRISS were the most frequently reported algorithms. Over 77% of the panels included trauma surgeons, 90% included other specialist; 61% emergency medicine physicians, 46% forensic pathologists and 43% nurses.

CONCLUSION

The definition of TRPD is not unambiguous in literature and should be based on a clinical definition completed with a trauma prediction algorithm such as the TRISS. TRPD panels should include a trauma surgeon, anesthesiologist, emergency physician, neurologist, and forensic pathologist.

Quantifying the need for pediatric REBOA: A gap analysis

BACKGROUND

Trauma is the leading cause of death in children. Resuscitative endovascular balloon occlusion of the aorta (REBOA) provides temporary hemorrhage control, but its potential benefit has not been assessed in children. We hypothesized that there are pediatric patients who may benefit from REBOA.

METHODS

Trauma patients <18 years old at a level 1 pediatric trauma center between 2009 and 2019 were queried for deaths, pre-hospital cardiac arrest, massive transfusion protocol activation, transfusion requirement, or hemorrhage control surgery. These patients defined the cohort of severely injured patients. From this cohort, patients with intraabdominal injuries for which REBOA may provide temporary hemorrhage control were identified, including solid organ injury necessitating intervention, vascular injury, or pelvic hemorrhage.

RESULTS

There were 239 severely injured patients out of 6538 pediatric traumas. Of these, 38 had REBOA-amenable injuries (15.9%) with 34.2% mortality, accounting for 10.2% of all pediatric trauma deaths at one center. Eleven patients with REBOA-amenable injuries had TBI (28.9%). Patients with REBOA-amenable injuries represented 0.6% of all pediatric traumas.

CONCLUSION

Nearly 20% of severely injured pediatric patients could potentially benefit from REBOA. The overall proportion of pediatric patients with REBOA-amenable injuries is similar to adult studies.

Causes of early mortality in pediatric trauma patients

BACKGROUND

Trauma is the leading cause of death in children, and most deaths occur within 24 hours of injury. A better understanding of the causes of death in the immediate period of hospital care is needed.

METHODS

Trauma admissions younger than 18 years from 2009 to 2019 at a Level I pediatric trauma center were reviewed for deaths (n = 7,145). Patients were stratified into ages 0-6, 7-12, and 13-17 years old. The primary outcome was cause of death, with early death defined as less than 24 hours after trauma center arrival.

RESULTS

There were 134 (2%) deaths with a median age of 7 years. The median time from arrival to death was 14.4 hours (interquartile range, 0.5-87.8 hours). Half (54%) occurred within 24 hours. However, most patients who survived initial resuscitation in the emergency department died longer than 24 hours after arrival (69%). Traumatic brain injury was the most common cause of death (66%), followed by anoxia (9.7%) and hemorrhage (8%). Deaths from hemorrhage were most often in patients sustaining gunshot wounds (73% vs. 11% of all other deaths, p < 0.0001), more likely to occur early (100% vs. 50% of all other deaths, p = 0.0009), and all died within 6 hours of arrival. Death from hemorrhage was more common in adolescents (21.4% of children aged 13-17 vs. 6.3% of children aged 0-6, and 0% of children aged 7-12 p = 0.03). The highest case fatality rates were seen in hangings (38.5%) and gunshot wounds (9.6%).

CONCLUSION

Half of pediatric trauma deaths occurred within 24 hours. Death from hemorrhage was rare, but all occurred within 6 hours of arrival. This is a critical time for interventions for bleeding control to prevent death from hemorrhage in children. Analysis of these deaths can focus efforts on the urgent need for development of new hemorrhage control adjuncts in children.

Nationwide use of REBOA in adolescent trauma patients: An analysis of the AAST AORTA registry

BACKGROUND

Trauma is the leading cause of death for children and adolescents. Resuscitative endovascular balloon occlusion of the aorta (REBOA) is a minimally invasive method of hemorrhage control used primarily in adults. We aimed to characterize REBOA use in pediatric patients.

METHODS

The American Association for the Surgery of Trauma (AAST) Aortic Occlusion for Resuscitation in Trauma and Acute Care Surgery (AORTA) registry was queried for patients <18 years old undergoing REBOA placement (2013-2020). The primary outcome was mortality. Secondary outcomes included injury severity score (ISS), additional interventions, and complications.

RESULTS

Eleven patients with a median age of 17 years old had REBOA placed, with a survival rate of 30%. Inflation of the REBOA balloon resulted in a significant increase in systolic blood pressure (SBP) (median SBP pre-REBOA 53 mmHg vs. post-REBOA 110 mmHg, p=0.0007). Patients were severely injured with a median ISS of 29 (interquartile range 16-42). There were no access-site complications. All three surviving patients had a discharge Glasgow Coma Scale of 15.

CONCLUSION

REBOA is used in patients <18 years old, but all reported patients in this registry were adolescents. No REBOA-related complications were reported. Identifying pediatric patients who may benefit from REBOA and modifying currently existing technology for this group of patients is an area of ongoing research.
