While airbags have saved many lives and are clearly beneficial overall, sodium hydroxide (NaOH) powder produced by the inflation reaction can cause significant alkali ocular injury if not irrigated promptly. Here we report a case of severe airbag related ocular alkali injury as a way to bring attention to the need for prompt ocular irrigation following motor vehicle accidents (MVA) with airbag deployment. A 47-year-old man was involved in a MVA with airbag deployment in a rural setting. Attention was paid to several other life-threatening traumatic injuries, however, ocular irrigation was not performed until some 6-7 hours after the MVA. Over the course of 6 months, airbag related alkali injury caused severe limbal ischemia, conjunctivalization of the cornea, corneal epithelial defects, cicatricial scarring, haze, and corneal/limbal vascularization despite amniotic membrane graft. Awareness of the importance of ocular irrigation following airbag deployment must be raised both in the ophthalmology and emergency medicine communities.
虽然安全气囊挽救了许多生命，总体上显然是有益的，但充气反应产生的氢氧化钠（NaOH）粉末如果不及时冲洗，会导致严重的眼部碱烧伤。在此，我们报告一例与安全气囊相关的严重眼部碱烧伤病例，以此引起人们对机动车事故（MVA）中安全气囊弹出后及时进行眼部冲洗必要性的关注。一名47岁男性在农村地区遭遇了一起安全气囊弹出的MVA。当时注意力集中在其他几处危及生命的创伤上，然而，直到MVA发生约6 - 7小时后才进行眼部冲洗。在6个月的时间里，尽管进行了羊膜移植，与安全气囊相关的碱烧伤仍导致了严重的角膜缘缺血、角膜结膜化、角膜上皮缺损、瘢痕形成、 haze以及角膜/角膜缘血管化。眼科和急诊医学界都必须提高对安全气囊弹出后眼部冲洗重要性的认识。
