The childhood air gun: serious injuries and surgical interventions

Toy Guns, Real Danger: An Update on Pediatric Injury Patterns Related to Nonpowder Weapons

BACKGROUND

Design changes of nonpowder guns, including BB and air guns, have significantly increased their potential to injure. We sought to characterize the demographics of children injured with nonpowder weapons and the specific injuries suffered.

METHODS

A cross-sectional analysis of the study years 2006, 2009, and 2012 was performed by combining the Kids' Inpatient Database into a single dataset. We identified cases (age < 21 years) of air gun injuries using external cause of injury codes. Patient characteristics and injuries were analyzed using ICD-9 codes, and national estimates were obtained using case weighting.

RESULTS

There were 1028 pediatric admissions for nonpowder weapon related injuries. The victims were predominately male (87.0%), non-Hispanic white (52.3%), resided in the South (47.3%), and in the lowest income quartile (39.2%). Half required a major surgical procedure. The predominant injuries were open wounds to the head, neck, or trunk (40.3%), and contusion (22.5%). Notable other injuries were intracranial injury (9.1%) and blindness or vision defects (3.3%).

CONCLUSIONS

The nonpowder weapons available to this generation can paralyze, blind, and cause lasting injury to children. Injuries frequently require surgical intervention, and these weapons should no longer be considered toys. Further research and legislation should be aimed at limiting children's access to these weapons.

Brain death of an infant caused by a penetrating air gun injury

Air guns are shooting projectiles (pellets) from the expansion of compressed air without involving any chemical reactions. Air guns are often regarded as harmless by the public, but these weapons can produce severe, sometimes lethal injuries, especially in children. A case of a penetrating head injury of an eleven-month-old infant, caused by an ordinary air gun pellet, is presented. The air gun pellet created an exceptionally severe brain injury, and brain death. The factors influencing the severity of air gun injuries - muzzle velocity, muzzle energy, skull thickness - are discussed.

Pediatric Cardiac Trauma in the United States: A Systematic Review

Literature discussing cardiac injuries in children is limited. Systematic search of PubMed identified 21 studies enrolling 1,062 pediatric patients who experienced cardiac trauma in the United States during the period 1961 to 2012. The predominant type of injury was blunt cardiac contusion affecting 59.7% (n = 634/1,062) of the study population. Motor vehicle crashes (53.5%, n = 391/731) were the leading cause of blunt cardiac trauma, while gunshot wounds (50%, n = 150/300) accounted for most penetrating injuries. Overall mortality rate was 35.2% (n = 374/1,062).

A comparison between non-powder gun and powder-gun injuries in a young pediatric population

INTRODUCTION

Non-powder guns (NPG) are viewed as toys for children by the general public. Literature on firearm injuries in the pediatric population is increasing, however there are still large gaps in the published literature regarding NPG. We intended to identify and compare the epidemiology, circumstances of injury and outcomes of children with NPG versus powder-gun injuries (GSW).

PATIENTS AND METHODS

We performed a 6-year retrospective analysis of children 0-14 years old treated for NPG and GSW injuries at our level one pediatric trauma center. Mann-Whitney U test and Pearson's X² were used to compare continuous and categorical variables, respectively.

RESULTS

There were 43 NPG and 112 GSWs. Patients were predominantly male (36 children; 84%) NPG vs. 92 children; 82% GSW) with a median age in both groups of 11 years. Analysis of residential zip codes showed that 74% (32 children) NPG injuries and 85% (95 children) GSW lived in regions with higher poverty than the national level. Children with NPG injuries were more likely to be Caucasian (24 children; 56%) and to have suffered an unintentional injury (36 children; 84%), while children with GSW were African-American (80 children; 71%; p=0.0002) and victims of assault (50 children; 45%; p<0.0001). When compared with NPG, children with GSW had more severe injuries, longer hospital stays, and higher overall mortality. There were no significant differences in rate of emergent OR intervention and ED mortality between the two groups.

CONCLUSION

Our results highlight two important findings. First, NPG injuries were accidental and thus preventable with improved legislation and public education. Second, health disparities related to gun violence among African-Americans are prevalent even in early childhood and prevention efforts should include this younger population.

Anesthesia for a thoracic BB gun injury

Pediatric anesthesiologists care for children with penetrating trauma from nonpowder (BB and pellet) guns. We present the case of a 9-year-old boy who required urgent median sternotomy for cardiac tamponade after sustaining a close-range BB gun injury to the chest. After summarizing the epidemiology of nonpowder gun injuries in children, we clarify the nomenclature, ballistics, and mechanisms of these guns, discuss the tendency to minimize these kinds of injuries, explain bullet embolization, and review (by body area) current clinical management issues.

Injury prevention advice in top-selling parenting books

OBJECTIVE

Parenting books are a commonly used source of information on how to keep children and adolescents safe from injuries, the leading cause of death and disability for children aged 1 to 18 years. The content and the quality of the messages contained in these books have not been evaluated formally. The objective of this study was to determine the quantity and the quality of injury prevention messages contained in popular parenting books.

METHODS

Top-selling parenting books for 2 major booksellers were reviewed to determine the presence and the accuracy of injury prevention messages as compared with those recommended by the American Academy of Pediatrics (AAP) through The Injury Prevention Program (TIPP) for younger children, aged 0 to 12 years, and the American Medical Association (AMA) through its Parent Package for the safety of adolescents.

RESULTS

Forty-six parenting books were reviewed, including 41 with messages related to younger children and 19 with messages related to adolescents. These books varied widely with regard to the number of injury prevention messages included. Although some books covered the great majority of TIPP messages for parents of young children, others included very few. In the case of books that address safety for adolescents, no book had more than half of the messages recommended by the AMA. Prevention of burns and motor vehicle injury were the most commonly addressed injury prevention topics in the books focused on younger children, whereas gun safety was the most prevalent injury prevention topic in books that focused on adolescents. Books that were authored by physicians addressed more of the recommended topics and messages than books that were written by authors from other professional backgrounds. The quality of messages was good, ie, consistent with the advice given by the AAP and the AMA. In only a few cases, the parenting books gave injury prevention advice that was inconsistent with recommendations.

CONCLUSIONS

Overall, books on parenting adolescents are less likely to contain injury prevention messages than those that address younger children. However, the most frequent injury prevention messages for parents of adolescents describe strategies to prevent firearm injury, a leading cause of death for children in this age group. More emphasis should be placed on prevention of motor vehicle injuries, especially as relates to adolescents. Pediatricians and primary care physicians need to be aware of the strengths and weaknesses of parenting manuals in providing adequate guidance related to injury prevention.

Injury risk of nonpowder guns

Nonpowder guns (ball-bearing [BB] guns, pellet guns, air rifles, paintball guns) continue to cause serious injuries to children and adolescents. The muzzle velocity of these guns can range from approximately 150 ft/second to 1200 ft/second (the muzzle velocities of traditional firearm pistols are 750 ft/second to 1450 ft/second). Both low- and high-velocity nonpowder guns are associated with serious injuries, and fatalities can result from high-velocity guns. A persisting problem is the lack of medical recognition of the severity of injuries that can result from these guns, including penetration of the eye, skin, internal organs, and bone. Nationally, in 2000, there were an estimated 21840 (coefficient of variation: 0.0821) injuries related to nonpowder guns, with approximately 4% resulting in hospitalization. Between 1990 and 2000, the US Consumer Product Safety Commission reported 39 nonpowder gun-related deaths, of which 32 were children younger than 15 years. The introduction of high-powered air rifles in the 1970s has been associated with approximately 4 deaths per year. The advent of war games and the use of paintball guns have resulted in a number of reports of injuries, especially to the eye. Injuries associated with nonpowder guns should receive prompt medical management similar to the management of firearm-related injuries, and nonpowder guns should never be characterized as toys.

Trends in BB/pellet gun injuries in children and teenagers in the United States, 1985-99

OBJECTIVE

To characterize national trends in non-fatal BB/pellet gun related injury rates for persons aged 19 years or younger in relation to trends in non-fatal and fatal firearm related injury rates and discuss these trends in light of injury prevention and violence prevention efforts.

SETTING

The National Electronic Injury Surveillance System (NEISS) includes approximately 100 hospitals with at least six beds that provide emergency services. These hospitals comprise a stratified probability sample of all US hospitals with emergency departments. The National Vital Statistics System (NVSS) is a complete census of all death certificates filed by states and is compiled annually.

METHODS

National data on BB/pellet gun related injuries and injury rates were examined along with fatal and non-fatal firearm related injuries and injury rates. Non-fatal injury data for all BB/pellet gun related injury cases from 1985 through 1999, and firearm related injury cases from 1993 through 1999 were obtained from hospital emergency department records using the NEISS. Firearm related deaths from 1985 through 1999 were obtained from the NVSS.

RESULTS

BB/pellet gun related injury rates increased from age 3 years to a peak at age 13 years and declined thereafter. In contrast, firearm related injury and death rates increased gradually until age 13 and then increased sharply until age 18 years. For persons aged 19 years and younger, BB/pellet gun related injury rates increased from the late 1980s until the early 1990s and then declined until 1999; these injury rates per 100 000 population were 24.0 in 1988, 32.8 in 1992, and 18.3 in 1999. This trend was similar to those for fatal and non-fatal firearm related injury rates per 100 000 which were 4.5 in 1985, 7.8 in 1993, and 4.3 in 1999 (fatal) and 38.6 in 1993 and 16.3 in 1999 (non-fatal). In 1999, an estimated 14 313 (95% confidence interval (CI) 12 025 to 16 601) cases with non-fatal BB/pellet gun injuries and an estimated 12 748 (95% CI 7881-17 615) cases with non-fatal firearm related injuries among persons aged 19 years and younger were treated in US hospital emergency departments.

CONCLUSIONS

BB/pellet gun related and firearm related injury rates show similar declines since the early 1990s. These declines coincide with a growing number of prevention efforts aimed at reducing injuries to children from unsupervised access to guns and from youth violence. Evaluations at the state and local level are needed to determine true associations.

Life-threatening air rifle injuries to the heart in three boys

Air rifles, or BB guns, are generally thought of as childhood toys. Although most injuries are not serious, life-threatening events have been reported. Within a 1-year period, 3 boys presented after BB gun shots to the chest, all requiring surgical intervention for penetrating injuries to the heart. A 15-year-old underwent window pericardiotomy for hemopericardium with thrombus 24 hours after admission. Another, 5 years of age, underwent emergent exclusion of the cardiac apex for a traumatic ventricular septal defect. The third, 8 years old, had a right ventricular injury requiring an urgent subxiphoid pericardial window for tamponade. All recovered uneventfully. Increased public awareness, adult supervision, safety training, and appropriate legislation are needed to decrease the risks of these potentially lethal weapons.

Childhood injury prevention at home and play

Unintentional injuries are the leading cause of death for children and adolescents in the United States, and they create a significant burden of disability and financial cost. If motor vehicle-associated injuries are not considered, children are most commonly injured in their home and play environments. The reduction over the past 20 years in childhood deaths related to motor vehicle injury has been significant, but rates of childhood death due to other causes, such as firearms, have increased. This review focuses on several categories of injuries other than motor vehicle injuries and highlights a few recent successful community- and practice-based injury-prevention programs. In addition, recent epidemiologic studies describing risk factors for injury-related death are discussed. Injuries due to interpersonal violence and motor vehicles are covered elsewhere.
