The effects of airbag deployment in motor vehicle accidents (MVA) on the fetus are poorly understood. A 22-year-old woman at 24 weeks of gestation collided with a telephone pole while driving. She was restrained and an airbag deployed. Although she had no major injuries, she experienced decreased fetal movements. Fetal heart rate (FHR) monitoring revealed loss of variability without any evidence of abruptio placentae, and 4 days later, the variability spontaneously recovered. Two weeks after the MVA, ultrasonography showed unilateral ventricular dilatation suggestive of fetal brain injury. Magnetic resonance imaging revealed subdural hematoma, intraventricular hemorrhage and cystic lesions, interpreted as indirect (hypoxic-ischemic) and direct (hemorrhagic) intracranial injuries. After MVA with airbag deployment, FHR monitoring can show a transient loss of variability, which may precede the appearance of fetal brain injury.
汽车事故（MVA）中安全气囊展开对胎儿的影响尚不清楚。一名22岁、孕24周的女性在驾车时与电线杆相撞。她系了安全带，安全气囊展开。尽管她没有受重伤，但她感觉到胎动减少。胎儿心率（FHR）监测显示变异性消失，没有任何胎盘早剥的迹象，4天后，变异性自行恢复。机动车事故两周后，超声检查显示单侧脑室扩张，提示胎儿脑损伤。磁共振成像显示硬膜下血肿、脑室内出血和囊性病变，被解释为间接（缺氧缺血性）和直接（出血性）颅内损伤。在安全气囊展开的机动车事故后，FHR监测可显示变异性短暂消失，这可能在胎儿脑损伤出现之前发生。
