The purpose of this study was to determine the effects of depowered frontal airbags on the incidence of severe upper extremity injuries.
The National Automotive Sampling System database files from 1993 to 2000 were examined in a study that included 2,413,347 occupants who were exposed to an airbag deployment in the United States.
Occupants exposed to a depowered airbag deployment were significantly more likely to sustain a severe upper extremity injury (3.9%) than those occupants exposed to a full-powered airbag deployment (2.5%) (P=.01). Full-powered systems resulted in an injury distribution of 89.2% fractures and 7.9% dislocations compared with depowered systems with 55.3% fractures and 44.3% dislocations.
Although depowered airbags were designed to reduce the risk of injuries, they appear to have increased the overall incidence of severe upper extremity injuries through a shift from long bone fractures to joint dislocations.
本研究的目的是确定减力型前排气囊对严重上肢损伤发生率的影响。
对1993年至2000年国家汽车抽样系统数据库文件进行了研究，该研究纳入了美国2413347名经历安全气囊展开的驾乘人员。
与经历全功率安全气囊展开的驾乘人员（2.5%）相比，经历减力型安全气囊展开的驾乘人员发生严重上肢损伤的可能性显著更高（3.9%）（P = 0.01）。全功率系统导致的损伤分布为89.2%骨折和7.9%脱位，而减力型系统为55.3%骨折和44.3%脱位。
尽管减力型安全气囊旨在降低受伤风险，但它们似乎通过从长骨骨折向关节脱位的转变增加了严重上肢损伤的总体发生率。
