Because laws mandating use of seat belts by motor vehicle drivers and front seat passengers have been passed throughout the developed world, it is becoming increasingly common to see parents protected from injuries whereas their children are abandoned to the tragic effects of chance and biomechanics. In France, the situation is especially critical. The law passed in 1975 requiring that all children use the back seat has reduced the risk of death and severe injury but nevertheless affords inadequate protection: each year, among children aged 0 to 10 years, several hundred are killed and nearly 10,000 injured in car accidents. This situation can be decisively improved, as shown by the figures in the United States and most European countries where use of child restraint devices (CRD) is mandatory. CRDs are designed to protect the child in the event of an accident by reducing the risk of injury due to ejection or projection against the inside of the vehicle: they play the same role as the seat belt for adults. France is the European country with the lowest rate of use of CRDs and the highest rate of child deaths due to motor vehicle occupant injuries. To improve this situation, regulations are being developed by the French government; use of appropriate CRDs will be mandatory for all children aged 0 to 10 years starting on January 1 st, 1992. 相似文献

Child restraint law effects on motor vehicle accident fatalities and injuries: the New Mexico experience 总被引:5,自引:0,他引:5
The New Mexico State Legislature passed a child restraint law applicable to children less than 5 years of age that became effective in June 1983. To evaluate the effectiveness of this law, we analyzed traffic accident data for New Mexico from January 1981 through September 1984. During this period, there were 20,972 children younger than 5 years of age in motor vehicle accidents. Restraint usage increased for this age group from a low of about 10% in 1981 to more than 40% in 1984 (P less than 10(-6)). Unrestrained children younger than 5 years of age were five times more likely to be killed and two times more likely to be injured than restrained children. Analysis of motor vehicle accident fatality and injury rates pre- and post-law revealed a 33% reduction in motor vehicle accident fatality rates and a 12.6% reduction in nonfatal injury rates for children younger than 5 years. We conclude that child restraint devices are effective in reducing motor vehicle accident fatalities and injuries in young children and the child restraint law has been effective in increasing child restraint usage and in reducing childhood death and injury in New Mexico. 相似文献

AIMS: To quantify the increased risk of non-fatal injury when children travel unrestrained in a car, and to identify other preventable risk factors. METHODS: Case-control study of 78 children presenting to an accident and emergency (A&E) department having sustained an injury while travelling in a car, and 97 children attending an A&E outpatient clinic with conditions unrelated to road traffic accidents. RESULTS: Seat restraint was associated with a 93% lower risk of child accident injury. A driver with points on the licence was over five times more likely to have had an accident resulting in child injury than a driver without points. Child accident injury was also associated with the driver's accident history. CONCLUSIONS: These data allow the effect of achieving new target levels of seat restraint use to be estimated. Strategies aimed at reducing the risk of further accident among drivers with a history of accident may have a beneficial impact on childhood accident injuries. 相似文献

Little is known about child passenger safety practice in China. This study aims to describe child passenger seating and restraint practice in Shanghai. Information on 970 children enrolled in five randomly selected kindergartens in the Songjiang and Pudong districts of Shanghai was collected from a parental survey during 2008-2009. The adjusted rate ratios for optimal (rear-seated alone) versus suboptimal seating position (including front-seated or sitting in adult laps) and restraint use versus non-use of restraints among child passengers were evaluated using multivariate binomial regression. Suboptimal seating position (16.9%) and non-use of restraints (60.8%) was common among child passengers. Younger age (≤4 years) and having parents who are licensed drivers decreased the likelihood of being rear-seated alone; whereas having a tertiary-educated mother increased the likelihood of a child being seated optimally. Compared with unlicensed parents, guardian parents who have a driver's licence were more likely to use restraints for their child passengers. This study suggests restraint non-use and suboptimal seating position are common for child passengers in the Songjiang and Pudong districts of Shanghai, and identifies risk factors influencing restraint use and seating position choice for child passengers. There is an urgent need to improve child passenger safety in China and these findings indicate potential targets for educational interventions in the absence of child restraint laws. 相似文献

In 2000, 1,668 child occupants under the age of 14 died in motor vehicle crashes and nearly 250,000 children were injured. When used correctly, child safety seats can dramatically reduce a child’s risk of death and serious injury in a motor vehicle crash. Emergency physicians have a unique opportunity to counsel parents and caregivers and provide recommendations on the appropriate restraint for their children as the majority of children in crashes who seek care are treated in emergency departments. The recommendations for child occupant protection are updated regularly. This paper will provide an overview of the current recommendations for restraining children in motor vehicles and identify sources for up to date information for physicians and families. 相似文献

Motor vehicle accidents are the leading cause of death in children. In 1977, Tennessee adopted the nation's first law requiring the use of child restraint devices (CRDs), but despite extensive promotional efforts, a majority of young children still travel unrestrained. We surveyed all acute-care hospitals in Tennessee to determine their policies regarding CRDs. Of 109 hospitals with obstetric services, 28 (26%) had a policy calling for discharged newborns to be transported in CRDs; only seven (5%) of 128 pediatric services had such a policy. It is time for hospitals and professional organizations to adopt policies to ensure that the parents of every child discharged from an obstetric or pediatric unit are educated concerning CRD use laws and are able to comply with them. Pediatricians should consider incorporating "discharge in child restraint device" into their routine discharge orders. 相似文献

Motor vehicle-related trauma is the leading cause of death in children in the United States. All states have pediatric restraint requirements for passenger vehicles to help prevent these deaths and injuries. Only a few states, however, possess safety laws or restrictions for passengers who ride in the back of pickup trucks. A retrospective review of medical records for a 40-month period revealed 40 patients whose injuries were a direct result of being a passenger in the cargo area (bed) of a pickup truck. Their injuries and other pertinent data are discussed. Representatives from the Highway Safety Commission of each state were surveyed about their specific highway safety laws. The responses revealed that all states and the District of Columbia have child restraint requirements for passenger automobiles, 34 states have adult restraint laws, but only 17 states have any type of restriction for passengers riding in the back of pickup trucks. Seventy-one percent of the states with pickup truck regulations include only the preschool-age child. Data from the National Highway Traffic Safety Administration concerning pickup trucks and passenger fatality are presented and discussed. 相似文献

INTRODUCTION: With the increased use of seat belts in motor vehicles, the frequency of morbidity and mortality associated with motor vehicle accidents may have decreased but there is an associated rise in injuries. The purpose of this study was to evaluate the risk of intra-abdominal injury in children who sustained Chance-type fractures in a motor vehicle accident. MATERIALS AND METHODS: A retrospective review was conducted of pediatric patients admitted for injuries sustained in motor vehicle accidents between 1984 and 2001. Patients that sustained lumbar Chance fractures and an abdominal injury were reviewed. RESULTS: A total of 25 patients with lumbar Chance fractures were seen at our institution; twelve had associated abdominal injuries. The mean age at the time of injury was 10.9 years and the most recent follow-up was a mean of 4.8 years after injury. All patients were involved in high-speed motor vehicle collisions. Eleven patients were restrained using a 2-point restraint and only one was restrained using a 3-point restraint. CONCLUSIONS: The abdominal injury patients had a significantly higher Chance fracture index than those patients who also suffered Chance fractures but no associated abdominal injuries. Success in the management of intra-abdominal injuries is dependent on the awareness that such an injury exists. 相似文献

AIM: To investigate the relationship between restraint usage and injury outcome in child motor vehicle occupants aged 2-8 years. METHODS: Retrospective case review of all child occupants presenting at the Children's Hospital at Westmead between July 2002 and January 2005 subsequent to a motor vehicle crash. Injury severity was assessed in terms of the Abbreviated Injury Scale (AIS), by age and type of restraint. RESULTS: Data were collected for 152 child occupants aged 2 and 8 years. While nearly all children (94%) used some restraint, most (82%) used a suboptimal form of restraint. Injury severity between optimally restrained children and suboptimally restrained children differed significantly (Fisher's exact test, P<0.001), with suboptimally restrained children receiving a greater proportion of moderate to severe (AIS 2+) injuries. No optimally restrained child sustained an AIS 2+ injury. CONCLUSION: A total of 82% of child occupants aged 2-8 years involved in crashes were suboptimally restrained. All children who sustained serious injuries were suboptimally restrained. There is a need to encourage correct use of the most appropriate restraint for child motor vehicle occupants in order to reduce the number and severity of injuries in these road users. 相似文献
