Restraint Use and Injury Patterns among Children Involved in Motor Vehicle Collisions

Motor vehicle collisions frequently result in serious or fatal inuries to occupants [1–4]. Frontal collisions are amongst the most severe types of accidents. The use of safety systems such as seat belts and airbags has been shown to reduce the severity of injuries sustained by occupants [5–10]. It is well known that frontal airbags act as supplemental restraints to seat belts in protecting occupants. Airbag deployment occurs through a reaction of chemicals in the inflator that rapidly produces gas and fills the canvas bag. The filled bag acts a cushion between the occupant and the vehicle’s interior components. The supplemental restraint provided by the airbag increases the amount of time and distance over which the occupant’s body decelerates, and accordingly reduces the potential for injury. The time at which the airbag deployment is initiated during the crash sequence can have an effect on the nature of the contact between occupant and airbag. Though properly timed, frontal airbags have been shown to reduce injuries sustained to occupants[11], it has been reported that airbags that deploy too late may cause injury[12]. To date, there have been a very limited number of studies that have addressed the biomechanical effects of late airbag deployment. The purpose of this study is to determine the biomechanical effects of late airbag deployment and restraint use on various sizes of occupants through computer simulation.

Significant Injury

This was a retrospective study examining severe injuries to Ohio children in order to provide pediatricians with targeted injury talking points at well visits. We included children ≤14 years old from the Ohio Trauma Acute Care Registry with severe unintentional injuries from January 1, 2003, to December 31, 2012. There were 45 347 patients; 611 died, and the mean age was 6.8 years. Fractures/dislocations were common (46.6%), and many injuries occurred at home (49.1%). In children ≤2 years old, the leading causes of injury were falls and burns/fire; falls and motor vehicle collisions (MVCs) predominated above this age. Leading causes of death were MVCs, drowning, and suffocation. We concluded that national data may not always reflect state-specific injury patterns. In Ohio, though falls and MVCs were the most common mechanisms, fire and drowning also caused significant injury. Given limited time to discuss injury prevention, pediatricians should concentrate on statewide injuries.
