Mechanisms of Pediatric Trauma Deaths in Canada and the United States: The Role of Firearms

The spectrum and management of noniatrogenic vascular trauma in the pediatric population

BACKGROUND

To describe the spectrum of noniatrogenic pediatric vascular injuries and their outcomes at a large tertiary pediatric hospital.

METHODS

Retrospective review of a prospectively-maintained trauma database, identifying children with noniatrogenic vascular injuries managed between 1994 and 2014.

RESULTS

A total of 198 patients were identified. Those patients with a digital or intracerebral vascular injury (92/198) were excluded from further analysis. The remaining 106 patients represented 1.2% of all traumas managed at our institution during the 21-year study period. The majority were male (75%), and between 1 and 12years of age (71% of all patients). Median time from trauma scene to any hospital was 48min (range 0-132), and most patients were transferred from another hospital (64%). Three patients were declared dead upon arrival (3%). Penetrating injuries accounted for most injuries (72%), while blunt injuries accounted for the remainder. Ulnar, radial, or brachial artery trauma accounted for 47% of injuries. Most vessels were treated operatively, by primary repair (49%), vessel ligation (15%), or interposition graft (12%). Fourteen patients (13%) were managed nonoperatively and most patients (74%) experienced no complications in hospital or during follow-up.

CONCLUSION

Noniatrogenic pediatric vascular injuries are rare and represent a highly heterogeneous population. Most children recover well, with minimal perioperative complications.

Orthopaedic firearm injuries in children and adolescents: An eight-year experience at a major urban trauma center

INTRODUCTION

The purpose of this study is to describe the epidemiology of orthopaedic injuries incurred secondary to firearms among children and adolescents at a major metropolitan trauma center and to identify risk factors for complications and long-term morbidity.

METHODS

A retrospective review was performed of consecutive patients 17 years of age and younger who sustained a firearm injury and required orthopaedic treatment at a major trauma center from 2006 to 2013. Patient demographics, injury mechanism, fracture classification, neurovascular injury, antibiotic administration, and length of hospitalization were recorded. Radiographic studies were used to determine fracture pattern, methods of stabilization, and time to union. Primary clinical outcomes include fracture nonunion, infection, and physeal arrest.

RESULTS

46 patients with a mean age of 12.7 years were treated for firearm related orthopaedic injuries. 72% of the patients were ages 13-17, while 28% were 12 years of age and younger. There were 28 violent injuries (21 assaults, 7 innocent bystanders) and 16 non-violent injuries (15 unintentional discharges and 1 self-inflicted). There was a bimodal distribution of violent versus nonviolent mechanisms, with the majority of children 12 years of age and under sustaining non-violent injuries and adolescents more commonly injured with a violent mechanism. There were 44 fractures and 6 traumatic arthrotomies, with eight associated neurovascular injuries. Twenty-five patients had an orthopaedic procedure, with a total of 43 surgeries. Mean hospital length of stay was 6.8 days. There were five deep infections. Four patients developed non-unions and all of these patients had deep infections. The timing and duration of antibiotic therapy was not significantly different between those who did and did not develop infection. Of the non-operatively treated fractures, there were no infections or non-unions at long-term follow-up.

CONCLUSIONS

Morbidity and mortality related to firearms is a growing public health problem in the United States. Results of this study suggest that gunshot related fractures had higher than anticipated morbidity, including permanent neurologic deficits, infection (11%) and fracture non-union (9%). More than half of patients underwent surgery and experienced long hospital stays secondary to the complexity of the injury. This epidemiological data on firearm injuries in children and adolescents is an impetus for prospective study, with the goal to increase awareness and develop treatment strategies for firearm-related fractures.

Pattern and epidemiology of pediatric musculoskeletal injuries in Kashmir valley, a retrospective single-center study of 1467 patients

This work aimed to study the pattern and epidemiology of pediatric musculoskeletal trauma and consequent morbidity in Kashmir Valley and compare the results with other studies and to formulate preventive measures and devise management strategies. This was a retrospective study of 1467 pediatric orthopedic trauma patients who presented to our hospital over a 3-year period between September 2005 and August 2008. Information was recorded in a prescribed proforma including the following: age, sex, mode of trauma, type of fracture/injury, radiological study, final diagnosis, intervention performed, and complications. The information was collected from the Medical Records Department of the hospital. The children's ages ranged from 0 to 16 years; there were 996 males and 471 females, with males outnumbering females in every age group (the overall male-to-female ratio was 2.12:1). Most fractures occurred in children aged 7-12 years [n=816 (53.96%)] and decreased in younger and older children beyond this age group. The left side was involved in 762 cases, 612 injuries involved the right side, 24 were bilateral, and 69 patients presented with multiple injuries. In children aged 0-6 years, the most common site of injury was the elbow, whereas in children aged 7-16 years, it was the forearm. In descending order, most injuries were sustained because of fall while playing (34.76%), fall from height (33.74%), road traffic accidents (14.92%), and fall from standing height (7.97%). The majority of injuries were caused by unintentional trauma (94.48 vs. 5.52%). The places where injury occurred were the home [603 (41.10%)], play field and orchards near the home [450 (30.67%)], roads [219 (14.92%)], school [183 (12.47%)], and unknown [12 (0.81%)]. The pattern and epidemiology of pediatric trauma differs from those in adults. The majority of musculoskeletal injuries are because of unintentional trauma in this young age group and hence preventable. Enhanced supervision at home and school is recommended. A safer environment and better playing conditions may decrease the high frequency of trauma in pediatric patients. Dedicated trauma centers with such facilities as orthopedics, neurosurgery, and plastic surgery need to be established for the proper management of pediatric trauma.

The impact of fatal pediatric trauma on aboriginal children

BACKGROUND/PURPOSE

Injuries are the leading cause of death in young people. Our aim is to examine the differences between aboriginal and non-aboriginal pediatric trauma mortality as a means to focus on prevention strategies.

METHODS

The records for all traumatic pediatric (0-18 years) deaths between 1996 and 2010 were reviewed from the regional Medical Examiner's office.

RESULTS

The majority of the total 932 pediatric deaths were the result of non-intentional injuries (640) followed by suicide (195), homicide (65), child abuse (15), and undetermined (17). Despite being only 3.3% of the provincial population, Aboriginals represented 30.9% of pediatric trauma fatalities. Aboriginal fatalities occurred most commonly in the home, with males and females equally affected. Road related events were the main causes of injury overall. Up to three-quarters of Aboriginal children who died in a non-pedestrian road related event did not wear an indicated protective device. Pedestrian deaths were over-represented in Aboriginal children. The second most common cause of death was suicide for both non-Aboriginal and Aboriginal children. Almost half of all of the suicides were Aboriginal. Homicide and child abuse had similar proportions for both non-Aboriginal and Aboriginal children.

CONCLUSION

Pediatric Aboriginal injury prevention should be a priority and tailored for Aboriginal communities.

Pediatric blunt and penetrating trauma deaths in Ontario: a population-based study

PURPOSE

The purpose of the study was to describe the mechanisms of injury and causes of death in children dying in a modern, integrated trauma system.

METHOD

Records of all children (<16 years of age) who died in Ontario from 2001 through 2003 after blunt or penetrating trauma were obtained from the Chief Coroner. Demographics and the nature and causes of injury and the causes of death were recorded. Estimates of the mortality rate were determined using census data.

RESULTS

There were 234 injury deaths (222 blunt, 12 penetrating) over the 3 years. Thirty (13%) resulted from intentional injury. The median age was 10 (range, 0-15.9) years; 62% were male. Sixty-eight percent resulted from incidents involving motor vehicles (passenger, pedestrian, or cyclist). Most (74%) died at the scene; only 5% survived for more than 24 hours. Devastating craniocervical injury (Abbreviated Injury Scale 5 or 6) was present in 84% and was the only life-threatening injury in 40%. The annual mortality rate averaged 3.2 per 100,000 children.

CONCLUSIONS

In a modern, integrated trauma system, most pediatric injury deaths occur at the scene from severe head injuries. In this population, strategies to reduce the death rate from pediatric trauma must focus on primary and secondary injury prevention.

Pediatric trauma deaths are predominated by severe head injuries during spring and summer

Background

Trauma is the most prevalent cause of death in the young. Insight into cause and time of fatal pediatric and adolescent trauma is important for planning trauma care and preventive measures. Our aim was to analyze cause, severity, mode and seasonal aspects of fatal pediatric trauma.

Methods

Review of all consecutive autopsies for pediatric fatal trauma during a 10-year period within a defined population.

Results

Of all pediatric trauma deaths (n = 36), 70% were males, with the gender increasing with age. Median age was 13 years (range 2–17). Blunt trauma predominated (by road traffic accidents) with most (n = 15; 42%) being "soft" victims, such as pedestrians/bicyclist and, 13 (36%) drivers or passengers in motor vehicles.

Penetrating trauma caused only 3 deaths. Prehospital deaths (58%) predominated. 15 children (all intubated) reached hospital alive and had severely deranged vital parameters: 8 were hypotensive (SBP < 90 mmHg), 13 were in respiratory distress, and 14 had GCS < 8 on arrival. Emergency procedures were initiated (i.e. neurosurgical decompression, abdominal surgery or pelvic fixation for hemorrhage) in 12 patients. Probability of survival (Ps) was < 33% in over 75% of the fatalities. A bimodal death pattern was evident; the initial peak by CNS injuries and exsanguinations, the latter peak by CNS alone. Most fatalities occurred during spring (53%) or summertime (25%).

Conclusion

Fatal pediatric trauma occurs most frequently in boys during spring/summer, associated with severe head injuries and low probability of survival. Preventive measures appear mandated in order to reduce this mortality in this age group.
