Airbags are intended to minimize facial injuries, alone and when used in combination with seatbelts in high-velocity motor-vehicle accidents. They may occasionally perforate, resulting in the release of sodium azide or sodium hydroxide, which result in chemical burns when in contact with skin. The force of deployment may itself result in significant blunt trauma, and there is a temperature rise during the inflation causing thermal burns, possibly as a separate and unnecessary consequence of a relatively minor accident.
A case report is presented. The literature on such injuries was reviewed and the mechanism of airbag deployment commented.
Alternative designs and mechanisms of linking the activation of the device to the velocity of travel or to add a switch which is activated when accessing a motorway are recommended.
安全气囊旨在将面部损伤降至最低，无论是单独使用还是在高速机动车事故中与安全带配合使用时。安全气囊偶尔会穿孔，导致叠氮化钠或氢氧化钠释放，接触皮肤时会造成化学灼伤。安全气囊展开的力量本身可能会导致严重的钝器伤，并且在充气过程中温度会升高，从而造成热灼伤，这可能是相对轻微事故中一个单独且不必要的后果。
本文呈现了一个病例报告。回顾了关于此类损伤的文献，并对安全气囊展开的机制进行了评论。
建议采用替代设计以及将设备激活与行驶速度相联系的机制，或者增加一个在进入高速公路时被激活的开关。
