BMJ:非创伤性ARDS出现巨大纵隔气肿——病例报道

2016-01-26 MedSci MedSci原创

男性患者,曾患有急性呼吸窘迫综合征现已恢复,接受压力通气支持(压力20 cm H2O,PEEP = 8 cm H2O)。现在患者右侧锁骨上窝出现皮下气肿。

男性患者,曾患有急性呼吸窘迫综合征现已恢复,接受压力通气支持(压力20 cm H2O,PEEP = 8 cm H2O)。现在患者右侧锁骨上窝出现皮下气肿。

胸部CT显示一个巨大的纵隔气肿,而并无气胸的表现(如下图所示),与Macklin效应的表现相符,Macklin效应是指钝性肺泡破裂,空气进入支气管血管鞘,还可进入纵膈(如箭头所示)。尽管Macklin效应通常发生于创伤后,但是有时也可发生于低PEEP值下的机械通气患者。



由于患者并没有出现气胸及纵膈偏移的现象,故采取保守治疗,但是有些病例需要进行胸腔引流和气管切开。
