Mechanical airway obstruction secondary to prevertebral hematoma following cervical spine injury is a life-threatening emergency. We present eight cases of mechanical airway obstruction from prevertebral hematomas in patients with cervical spine injury. They are combined with 13 previously reported cases to produce a study population of 21 patients. Although it is a rare complication of cervical spine injury, swelling significant enough to cause airway obstruction should be anticipated in all patients, regardless of age, severity of trauma, or lack of symptoms. To date, this phenomenon has not been reported in injuries below C6. Additionally, because symptoms may take hours to develop, initial cervical radiographs may not show evidence of retropharyngeal swelling and impending airway obstruction.
颈椎损伤继发于椎体前血肿的机械性气道梗阻是一种危及生命的紧急情况。我们报告了8例颈椎损伤患者因椎体前血肿导致的机械性气道梗阻病例。将这些病例与之前报告的13例病例合并，形成了一个21例患者的研究群体。尽管这是颈椎损伤的一种罕见并发症，但无论患者年龄、创伤严重程度或有无症状，都应预计到肿胀严重到足以导致气道梗阻的情况。迄今为止，C6以下损伤尚未报告过这种现象。此外，由于症状可能需要数小时才会出现，最初的颈椎X线片可能无法显示咽后肿胀和即将发生的气道梗阻的迹象。
