Early management of pediatric vascular injuries through humanitarian surgical care during U.S. military operations

A decade of managing pediatric major traumatic vascular injuries: insights from a referral center

PURPOSE

Incidence, management, and outcomes of pediatric vascular injuries secondary to non-iatrogenic trauma were reviewed over a decade in our institution.

METHODS

A retrospective review of medical records (2013-2022) of major traumatic vascular injuries, focusing on injury profiles, treatment modalities, and clinical outcomes.

RESULTS

Thirty patients with 48 vessel injuries were included. Firearms were the leading mechanism, accounting for 43.3% (n = 13) of cases. We identified 29 arterial injuries and 19 venous injuries, with 30 (62.5%) of the overall injuries occurred in the lower extremities. Shock (17; 56.7%) and associated injuries (25; 83.3%) were common. Surgery was the most common management strategy. Autologous bypass graft was the most frequently performed procedure for arterial injuries (8; 42.1%), while ligation dominated in venous injuries (9; 64.3%). Blood transfusion requirements (24; 82.7%) and post-operative prescription of anticoagulant and antiplatelet agents (12; 41.4%) were similar for arterial and venous injuries (p > 0.05). Three patients demised, resulting in a 90% survival rate. Neither the mechanism of injury, anatomical location, and presence of shock on arrival nor the baseline hemoglobin level served as predictors of mortality.

CONCLUSION

Intensive resuscitation with blood transfusion and prompt surgical intervention achieve favorable survival rates for pediatric traumatic vascular injuries. Optimal post-operative anticoagulant and antiplatelet regimens remain unclear.

Age-Specific Strategies in Pediatric Vascular Trauma: A Comparative Analysis of Surgical and Heparin-Based Conservative Treatments

Background Pediatric vascular trauma, although rare, poses significant clinical challenges due to the potential for long-term morbidity, including limb compromise and growth abnormalities. This study addresses the gap in standardized treatment protocols by evaluating the efficacy of heparin-based conservative treatments compared to surgical interventions in children under 13 years of age. Methods A retrospective observational study was conducted at a referral center, reviewing institutional records from January 2010 to December 2020. The study included 27 pediatric patients aged up to 13 years who sustained arterial trauma involving the brachial and femoral arteries. Injuries were categorized as penetrating, blunt, or iatrogenic. Patients were divided into two age groups: those below six years and those six years and above. Treatment modalities were categorized into open surgical repair and medical management with unfractionated heparin. The diagnosis was confirmed through physical examination, Doppler ultrasound, and angiography. Results Out of 27 patients, 17 underwent surgical intervention, while 10 received medical management with heparin. An overall limb salvage rate of 87% was achieved. One case of limb loss occurred in a patient under six years who underwent surgical intervention. No significant limb-length discrepancies were observed. Surgical approaches, particularly interposition vein grafting, effectively restored palpable distal pulses. The results highlight the importance of an age-specific approach, demonstrating the effectiveness of both surgical and conservative treatments. Conclusion The study underscores the necessity for age-specific treatment protocols in pediatric vascular trauma. Individualized care resulted in high rates of limb salvage and favorable outcomes. These findings contribute to enhancing the understanding and management of pediatric vascular trauma, promoting the development of nuanced, age-tailored treatment protocols in clinical practice.

A scoping review of two decades of pediatric humanitarian care during wartime

ABSTRACT

Humanitarian care is a vital component of the wartime mission. Children comprise a significant proportion of casualties injured by explosives and penetrating weapons. Children face a variety of unique injury patterns in the combat setting as high-powered firearms and explosives are rarely seen in the civilian setting. We sought to perform a scoping review of pediatric research from the recent US-led wars in Afghanistan, and Iraq conflicts beginning in 2001. We used Google Scholar and PubMed to identify pediatric combat literature published between 2001 and 2022. We utilized the PRISMA-ScR Checklist to conduct this review. We identified 52 studies that met inclusion for this analysis-1 prospective observational study, 50 retrospective studies, and 1 case report. All the original research studies were retrospective in nature except for one. We identified one prospective study that was a post hoc subanalysis from an overall study assessing the success of prehospital lifesaving interventions. Most of the articles came from varying registries created by the United States and British militaries for the purposes of trauma performance improvement. The deployed health service support mission often includes treatment of pediatric trauma patients. The deployed health service support mission often includes treatment of pediatric trauma patients. We found that available literature from this setting is limited to retrospective studies except for one prospective study. Our findings suggest that pediatric humanitarian care was a significant source of medical resource consumption within both of the major wars. Further, many of the lessons learned have directly translated into changes in civilian pediatric trauma care practices highlighting the need for collaborative scientific developments between the military and civilian trauma programs.

Management of a Pediatric Type 3C Open Femoral Fracture Following a High-Velocity Gunshot Wound at an Adult Level II Trauma Center

ABSTRACT

We present a case of a 10-year-old girl shot in the thigh by a stray bullet who had a favorable outcome when treated with a multidisciplinary approach at the nearest nonpediatric level II trauma center. Point-of-care thromboelastography facilitated effective resuscitation based on her coagulation profile, minimized blood product use, and allowed for damage-control surgery to stabilize and revascularize her complex femur fracture.

Pediatric intracranial arterial injuries by penetrating gunshot wounds: an institutional experience

PURPOSE

Pediatric intracranial injuries due to penetrating gunshot wounds are a rare entity that is often fatal. A subset of patients may experience an intracerebral arterial injury; however, literature on the pediatric population is limited. This study analyzes a large institution's experience with pediatric head gunshot wounds and intracranial arterial injuries.

METHODS

All pediatric patients ≤ 18 years of age who presented to our institution with a penetrating gunshot wound from 2008 to 2018 were retrospectively analyzed.

RESULTS

Thirty-seven patients presented with an intracerebral penetrating gunshot injury. There were 18 deaths (49%) in the cohort. A total of 20 patients (54%) had vascular imaging. Of the remaining 17 patients with no vascular imaging, 13 (35%) died before any vascular studies were obtained. Four (20%) of the 20 patients with vascular imaging experienced an intracerebral arterial injury. Three of these 4 patients died before treatment could be administered. One patient with a firearm injury underwent embolization of a distal middle cerebral artery pseudoaneurysm and was discharged home with a Glasgow Outcome Scale score of 5 on follow-up.

CONCLUSION

Pediatric patients with penetrating intracranial gunshot wounds often die before vascular imaging can be obtained.

Effectiveness of the combat application tourniquet for arterial occlusion in young children

BACKGROUND

Tourniquet use for extremity hemorrhage has become a mainstay in adult trauma care in last 15 years. The efforts of the Stop the Bleed campaign have increased the distribution and use of tourniquets in civilian settings in response to mass shootings and as part of disaster preparedness. Little research or published experience exists regarding the use of tourniquets in the pediatric population. This study sought to determine the minimum patient age on which the combat application tourniquet (CAT) is able to control extremity hemorrhage.

METHODS

A convenience sample of pediatric patients, ages 1 year to 8 years, scheduled for elective orthopedic surgery at an academic hospital, were eligible for enrollment. Subject age, weight, height, blood pressure, and arm and leg circumferences were obtained. Once under general anesthesia, the pulse of an upper and a lower limb were obtained by Doppler, a CAT was then placed at the most proximal practical location of the limb until the corresponding pulse was either no longer obtainable by Doppler or until the tourniquet was as tight as its design allows. The tourniquet was removed after 30 seconds of arterial occlusion.

RESULTS

Thirteen children, ages 2 years to 7 years were enrolled. Weights ranged from 12.8 kg to 23.9 kg, with a mean of 16.7 kg. Leg circumferences were 24.5 cm to 34.5 cm, with a mean of 27.9 cm and arm circumferences were 13 cm to 24 cm, with a mean of 16.3 cm. Subject heights were 87 cm to 122 cm, with a mean of 103.4 cm. Twenty-four total extremities were tested, 11 arms and 13 legs. Arterial occlusion was obtained on 100% of limbs tested (95% confidence interval, 85.8-100%).

CONCLUSION

This study is similar to previous adult tourniquet efficacy studies in design, size and outcomes. It is the first to show successful arterial occlusion on preschool-aged children with a commercial tourniquet in a controlled setting. The results suggest that the CAT can be used in school-aged children with severe extremity hemorrhage with a high likelihood of success.

Prehospital Life-Saving Interventions Performed on Pediatric Patients in a Combat Zone: A Multicenter Prospective Study

OBJECTIVES

We aimed to describe and evaluate prehospital life-saving interventions performed in a pediatric population in the Afghanistan theater of operations.

DESIGN

Our study was a post hoc, subanalysis of a larger multicenter, prospective, observational study.

SETTING

We evaluated casualties enrolled upon admission to one of the nine military medical facilities in Afghanistan between January 2009 and March 2014.

PATIENTS

Adult and pediatric (<17 yr old) patients.

MEASUREMENTS

We conducted initial descriptive analyses followed by comparative tests. For comparative analysis, we stratified the study population (adult vs pediatric), and subsequently, we compared injury descriptions and the interventions performed. Following tests for normality, we used the t test or Wilcoxon rank-sum test (nonparametric) for continuous variables and chi-square or Fisher exact for categorical variables. We reported percentages and 95% CIs.

MAIN RESULTS

We enrolled 2,106 patients, of which 5.6% (n = 118) were pediatric. Eighty-two percent of the pediatric patients were male, and 435 had blast related injuries. A total of 295 prehospital life-saving interventions were performed on 118 pediatric patients, for an average of 2.5 life-saving interventions per patient. Vascular access (IV 96%, intraosseous 91%) and hypothermia prevention-related interventions (69%) were the most common. Incorrectly performed life-saving interventions in pediatric patients were rare (98% of life-saving interventions performed correctly) and n equals to 24 life-saving interventions over the 6-year period were missed. The most common incorrectly performed and missed life-saving interventions were related to vascular access. When compared with adult life-saving interventions received in the prehospital environment, pediatric patients were more likely to receive intraosseous access (p < 0.0001), whereas adult patients were more likely to have a tourniquet placed (p = 0.0019), receive wound packing with a hemostatic agent (p = 0.0091), and receive chest interventions (p = 0.0003).

CONCLUSIONS

In our study, the most common intervention was vascular access followed by hypothermia prevention and hemorrhage control. The occurrence of missed or incorrectly performed life-saving interventions were rare.

Delivering trauma and rehabilitation interventions to women and children in conflict settings: a systematic review

Background

In recent years, more than 120 million people each year have needed urgent humanitarian assistance and protection. Armed conflict has profoundly negative consequences in communities. Destruction of civilian infrastructure impacts access to basic health services and complicates widespread emergency responses. The number of conflicts occurring is increasing, lasting longer and affecting more people today than a decade ago. The number of children living in conflict zones has been steadily increasing since the year 2000, increasing the need for health services and resources. This review systematically synthesised the indexed and grey literature reporting on the delivery of trauma and rehabilitation interventions for conflict-affected populations.

Methods

A systematic search of literature published from 1 January 1990 to 31 March 2018 was conducted across several databases. Eligible publications reported on women and children in low and middle-income countries. Included publications provided information on the delivery of interventions for trauma, sustained injuries or rehabilitation in conflict-affected populations.

Results

A total of 81 publications met the inclusion criteria, and were included in our review. Nearly all of the included publications were observational in nature, employing retrospective chart reviews of surgical procedures delivered in a hospital setting to conflict-affected individuals. The majority of publications reported injuries due to explosive devices and remnants of war. Injuries requiring orthopaedic/reconstructive surgeries were the most commonly reported interventions. Barriers to health services centred on the distance and availability from the site of injury to health facilities.

Conclusions

Traumatic injuries require an array of medical and surgical interventions, and their effective treatment largely depends on prompt and timely management and referral, with appropriate rehabilitation services and post-treatment follow-up. Further work to evaluate intervention delivery in this domain is needed, particularly among children given their specialised needs, and in different population displacement contexts.

Blast injuries in children: a mixed-methods narrative review

BACKGROUND AND SIGNIFICANCE

Blast injuries arising from high explosive weaponry is common in conflict areas. While blast injury characteristics are well recognised in the adults, there is a lack of consensus as to whether these characteristics translate to the paediatric population. Understanding blast injury patterns in this cohort is essential for providing appropriate provision of services and care for this vulnerable cohort.

METHODS

In this mixed-methods review, original papers were screened for data pertaining to paediatric injuries following blasts. Information on demographics, morbidity and mortality, and service requirements were evaluated. The papers were written and published in English from a range of international specialists in the field.

RESULTS

Children affected by blast injuries are predominantly male and their injuries arise from explosive remnants of war, particularly unexploded ordinance. Blasts show increased morbidity and mortality in younger children, while older children have injury patterns similar to adults. Head and burn injuries represent a significant cause of mortality in young children, while lower limb morbidity is reduced compared with adults. Children have a disproportionate requirement for both operative and non-operative service resources, and provisions for this burden are essential.

CONCLUSIONS

Certain characteristics of paediatric injuries arising from blasts are distinct from that of the adult cohort, while the intensive demands on services highlight the importance of understanding the diverse injury patterns in order to optimise future service provisions in caring for this child blast survivor.

Tourniquet usage in prehospital care and resuscitation of pediatric trauma patients-Pediatric Trauma Society position statement

BACKGROUND

Recent mass casualty events in the United States have highlighted the need for public preparedness to prevent death from uncontrolled hemorrhage. The Pediatric Trauma Society (PTS) reviewed the literature regarding pediatric tourniquet usage with the aim to provide recommendations about the utility of this adjunct for hemorrhage control in children.

METHODS

Search terms "pediatric" and "tourniquet" were used to query the US National Library of Medicine National Institutes of Health for pertinent literature. Exclusion criteria include not involving children, not involving the use of an extremity tourniquet, primary outcomes not related to hemorrhage control, tourniquet use to prevent snake envenomation, single case reports, and only foreign language formats available. Bibliographies of remaining studies reviewed to identify additional pertinent research. Four physician members of the PTS Guidelines Committee reviewed identified studies.

RESULTS

One hundred thirty-four studies were identified. One hundred twenty-three studies were excluded. Seven additional studies were identified through bibliography review. Eighteen pertinent studies were reviewed. Seven articles evaluated physiologic response to tourniquet use in operating room settings. Six articles were generated from combat experience in conflicts in Afghanistan and Iraq. Four articles discussed technical details of tourniquet usage. One article evaluated the use of tourniquets during the Boston Marathon bombing in 2015.

CONCLUSION

Despite limited data of limited quality regarding their use, the PTS supports the usage of tourniquets in the prehospital setting and during the resuscitation of children suffering from exsanguinating hemorrhage from severe extremity trauma. Expedited, definitive care must be sought, and tourniquet pressure and time should be limited to the least amount possible. The Society supports the ACS "Stop the Bleed" campaign and encourages further investigation of tourniquet use in children.

Emergency department imaging of pediatric trauma patients during combat operations in Iraq and Afghanistan

BACKGROUND

Military hospitals in Iraq and Afghanistan treated children with traumatic injuries during the recent conflicts. Diagnostic imaging is an integral component of trauma management; however, few published data exist on its use in the wartime pediatric population.

OBJECTIVE

The authors describe the emergency department (ED) utilization of radiology resources for pediatric trauma patients in Iraq and Afghanistan.

MATERIALS AND METHODS

We queried the Department of Defense Trauma Registry (DODTR) for all pediatric patients admitted to military fixed-facility hospitals in Iraq and Afghanistan from January 2007 to January 2016. We retrieved ED data on ultrasound (US), radiographic and computed tomography (CT) studies.

RESULTS

During the study period, there were 3,439 pediatric encounters, which represented 8.0% of all military hospital trauma admissions. ED providers obtained a total of 12,376 imaging studies on 2,920 (84.9%) children. Of the 12,376 imaging studies, 1,341 (10.8%) were US, 4,868 (39.3%) were radiographic and 6,167 (49.8%) were CT exams. Most children undergoing radiographic evaluation were boys (77.8%) and located in Afghanistan (70.4%), and they sustained penetrating injuries (68.0%). Children who underwent imaging had higher composite injury severity scores in comparison to those who did not undergo imaging (10 versus 9).

CONCLUSION

Military health care providers frequently utilized radiographic studies in the evaluation of pediatric trauma casualties in Iraq and Afghanistan. Deployed military hospitals that treat children would benefit from dedicated pediatric-specific imaging training and protocols.

Prehospital Interventions Performed on Pediatric Trauma Patients in Iraq and Afghanistan

BACKGROUND

United States (US) and coalition military medical units deployed to combat zones frequently encounter pediatric trauma patients. Pediatric patients may present unique challenges due to their anatomical and physiological characteristics and most military prehospital providers lack pediatric-specific training. A minimal amount of data exists to illuminate the prehospital care of pediatric patients in this environment. We describe the prehospital care of pediatric trauma patients in Iraq and Afghanistan.

METHODS

We queried the Department of Defense Trauma Registry (DODTR) for all pediatric subjects admitted to US and Coalition fixed-facility hospitals in Iraq and Afghanistan from January 2007 to January 2016. Subjects were grouped by age: <1, 1-4, 5-9, 10-14, and 15-17 years. We focused our analysis on interventions related to trauma resuscitation.

RESULTS

Of 42,790 encounters in the DODTR during the study period, 3,439 (8.0%) were aged <18 years. Most subjects were in the 5-9 age group (33.1%), male (77.1%), located in Afghanistan (67.8%), injured by explosives (43.1%). Most subjects survived to hospital discharge (90.2%). The most frequently performed interventions were tourniquet placement (6.6%), intubation (6.1%), supplemental oxygen (11.7%), IV access (24.8%), IV fluids (13.3%), IO access (5.1%), and hypothermia prevention (44.5%). The most frequently administered medications were antibiotics (6.2%) and opioids (15.0%). Most procedural and medication interventions occurred in subjects injured by explosives (43.1%) and gunshot wounds (22.1%).

CONCLUSIONS

Pediatric subjects comprised over 1 in 13 casualties treated in the joint theaters with the majority injured by explosives. Vascular access and hypothermia prevention interventions were the most frequently performed procedures.

Emergency department resuscitation of pediatric trauma patients in Iraq and Afghanistan

BACKGROUND

Military hospital healthcare providers treated children during the recent conflicts in Afghanistan and Iraq. Compared to adults, pediatric patients present unique challenges during trauma resuscitations and have notably been discussed in few research reports. We seek to describe ED interventions performed on pediatric trauma patients in Iraq and Afghanistan.

METHODS

We queried the Department of Defense Trauma Registry (DODTR) for all pediatric patients in Iraq and Afghanistan from January 2007 to January 2016. Subjects were grouped based on Centers for Disease Control age categories. We used descriptive statistics.

RESULTS

During this period, there were 3388 pediatric encounters that arrived at the ED with signs of life or on-going interventions. Most subjects were male (77.2%), located in Afghanistan (67.9%), injured by explosive (43.2%), and admitted to an intensive care unit (57.8%). Most of those arriving to the ED alive or with on-going interventions survived to hospital discharge (91.6%). The most frequently encountered age group was 5-9years (33.3%) followed by 10-14years (31.5%). The most common interventions were vascular access (86.6%), fluid administration (85.0%), and external warming (44.6%). Intubation was the most frequent airway intervention (18.2%). Packed red blood cells were the most frequently administered blood product (33.8% of subjects).

CONCLUSIONS

Pediatric subjects accounted for a notable portion of care delivered in theater emergency departments during the study period. Vascular access and fluid administration were the most frequently performed interventions. Pediatric-specific training is needed as a part of deployment medicine operations.

[And if it happened to children? Adapting medical care during terrorist attacks with multiple pediatric victims]

In light of the recent terrorist attacks in Europe, we need to reconsider the organization of rescue and medical management and plan for an attack involving multiple pediatric victims. To ensure quick surgical management, but also to minimize risk for on-site teams (direct threats from secondary terrorist attacks targeting deployed emergency services), it is crucial to evacuate patients in a swift but orderly fashion. Children are vulnerable targets in terrorist attacks. Their anatomical and physiological characteristics make it likely that pediatric victims will suffer more brain injuries and require more, often advanced, airway management. Care of multiple pediatric victims would also prove to be a difficult emotional challenge. Civilian medical teams have adapted the military-medicine principles of damage control in their medical practice using the MARCHE algorithm (Massive hemorrhage, Airway, Respiration [breathing], Circulation, Head/Hypothermia, Evacuation). They have also learned to adapt the level of care to the level of safety at the scene. Prehospital damage control principles should now be tailored to the treatment of pediatric patients in extraordinary circumstances. Priorities are given to hemorrhage control and preventing the lethal triad (coagulopathy, hypothermia, and acidosis). Managing hemorrhagic shock involves quickly controlling external bleeding (tourniquets, hemostatic dressing), using small volumes for fluid resuscitation (10-20ml/kg of normal saline), quickly introducing a vasopressor (noradrenaline 0.1μg/kg/min then titrate) after one or two fluid boluses, and using tranexamic acid (15mg/kg over 10min for loading dose, maximum 1g over 10min). Prehospital resources specifically dedicated to children are limited, and it is therefore important that everyone be trained and prepared for a scene with multiple pediatric patients.

Data collection tools for maternal and child health in humanitarian emergencies: a systematic review

OBJECTIVE

To describe tools used for the assessment of maternal and child health issues in humanitarian emergency settings.

METHODS

We systematically searched MEDLINE, Web of Knowledge and POPLINE databases for studies published between January 2000 and June 2014. We also searched the websites of organizations active in humanitarian emergencies. We included studies reporting the development or use of data collection tools concerning the health of women and children in humanitarian emergencies. We used narrative synthesis to summarize the studies.

FINDINGS

We identified 100 studies: 80 reported on conflict situations and 20 followed natural disasters. Most studies (76/100) focused on the health status of the affected population while 24 focused on the availability and coverage of health services. Of 17 different data collection tools identified, 14 focused on sexual and reproductive health, nine concerned maternal, newborn and child health and four were used to collect information on sexual or gender-based violence. Sixty-nine studies were done for monitoring and evaluation purposes, 18 for advocacy, seven for operational research and six for needs assessment.

CONCLUSION

Practical and effective means of data collection are needed to inform life-saving actions in humanitarian emergencies. There are a wide variety of tools available, not all of which have been used in the field. A simplified, standardized tool should be developed for assessment of health issues in the early stages of humanitarian emergencies. A cluster approach is recommended, in partnership with operational researchers and humanitarian agencies, coordinated by the World Health Organization.

The hidden war: humanitarian surgery in a combat zone

BACKGROUND

Humanitarian surgical care (HSC) provided during wartime plays a substantial role in military operations, but has not been described or quantified beyond individual experiences.

METHODS

Prospective survey was conducted of all military members deployed to Iraq or Afghanistan between 2002 and 2011.

RESULTS

There were 266 responses. On average, surgeons had been in practice for 3 years at their 1st deployment and the majority were not fellowship trained. HSC was performed on all body systems and patient populations, including surgery for malignancy. Although 30% of responders performed surgeries they had never done before as a staff surgeon, 84% felt well prepared by their residency. The majority felt that performing HSC improved unit readiness (60%), benefited local population (64%), and contributed to counterinsurgency operations (54%).

CONCLUSION

Over our 10-year period, hundreds of military surgeons performed countless HSC cases in Iraq and Afghanistan and the majority felt that HSC had numerous benefits.
