Cerebral air embolism is a rare clinical entity in day-to-day practice. The introduction of air into the venous or the arterial system can cause cerebral air embolism leading to severe neurological deficits. The common causes reported in the literature are iatrogenic; it can be caused by positive pressure maneuvers performed during cardiac resuscitation, lung biopsy, and the placement of venous catheters in the presence of a patent foramen ovale. We report a case of cerebral air embolism which has occurred secondary to lung laceration. The patient underwent intercostal drainage for hydro-pneumothorax and developed forceful cough and suddenly changed in consciousness. Air embolism was diagnosed by computed tomography brain and was managed by high-concentration oxygen therapy and other supportive measures and is being discharged in satisfactory condition.
脑空气栓塞在日常医疗实践中是一种罕见的临床病症。空气进入静脉或动脉系统可导致脑空气栓塞，进而引发严重的神经功能缺损。文献报道的常见病因是医源性的；它可由心脏复苏、肺活检以及在存在卵圆孔未闭的情况下放置静脉导管时进行的正压操作引起。我们报告一例继发于肺裂伤的脑空气栓塞病例。该患者因血气胸接受肋间引流，出现剧烈咳嗽并突然意识改变。脑部计算机断层扫描诊断为空气栓塞，通过高浓度氧疗及其他支持措施进行治疗，患者现病情好转已出院。
