The authors report a case of fatal aspiration of thick barium during esophagography in a 75-year-old woman. Apparently the patient held much of the barium in her mouth and then aspirated it as she tried to swallow. The authors suggest that thick barium be avoided when fluoroscopy shows that the patient has difficulty in swallowing thin barium and that a suction machine equipped with a large-bore catheter be readily available during esophagography, particularly in the elderly or obtunded patient.
作者报告了一例75岁女性在食管造影检查期间因误吸浓稠钡剂而死亡的病例。显然，患者口中含着大量钡剂，然后在试图吞咽时将其误吸。作者建议，当荧光透视显示患者吞咽稀薄钡剂有困难时，应避免使用浓稠钡剂，并且在食管造影检查期间应随时准备好配备大口径导管的吸引器，尤其是对于老年患者或意识不清的患者。
