BACKGROUND
The type of injuries caused by sport utility vehicles may be different from those caused by small passenger cars. We studied prospectively the effects of the offending vehicle type and design on severity and pattern of pedestrian injuries.
METHODS
All injured pedestrians admitted to the two major trauma centers of Al-Ain city were studied prospectively during the period of April 2006 to October 2007. Patients were classified into two groups according to the offending vehicle type: small vehicle and sport utility vehicle. These two groups were compared regarding the distribution of injury and its severity.
RESULTS
The anatomical distribution of injury in a descending order were the lower extremities (56.3, 67 %), head (53.8, 57.1 %), face (37.5, 57.1 %), and upper extremities (32.5, 28.6 %) in small vehicle and sport utility vehicle groups, respectively. No significant statistical difference has been found between the two groups regarding the anatomical distribution and severity.
CONCLUSIONS
The vehicle size and design did not affect the anatomical injury distribution and severity in our setting. High-impact speed may overcome the vehicle type when it comes to injury severity and pattern of distribution.
背景
运动型多用途汽车（SUV）造成的损伤类型可能与小型乘用车不同。我们前瞻性研究了肇事车辆类型和设计对行人损伤严重程度和类型的影响。
方法
在 2006 年 4 月至 2007 年 10 月期间，我们前瞻性研究了收治于艾因市两家主要创伤中心的所有受伤行人。根据肇事车辆类型将患者分为两组：小型车和 SUV。比较这两组的损伤分布及其严重程度。
结果
按照损伤严重程度降序排列，小型车和 SUV 组的解剖学分布分别为下肢（56.3%、67%）、头部（53.8%、57.1%）、面部（37.5%、57.1%）和上肢（32.5%、28.6%）。两组之间在解剖学分布和严重程度方面无显著统计学差异。
结论
在我们的研究中，车辆尺寸和设计并未影响解剖学损伤分布和严重程度。高冲击力速度可能会克服车辆类型对损伤严重程度和分布类型的影响。
