This is a brief review of some of the physiological consequences of air embolism, followed by a discussion of the results of a comparative study between two consecutive series of patients, the first prior to the introduction of the strict routines now practised, and the second after this had been introduced. The techniques in current use for prophylaxis against air embolism are presented.
The incidence and outcome of systemic air embolism occurring in 520 patients have been estimated from records of cerebral disturbance. Two series of patients are compared, the first prior to the introduction of strictly planned "debubbling", and the second after this time. The comparisons shows a marked fall in the incidence and severity of this complication in the recent series. Techniques used for removal of air in specific operations have been presented. Pulmonary air embolism has been discussed. While no direct relationship between bilateral atelectasis and pulmonary air embolism has been shown, there is a strong probability that it has been in the past responsible for this, at least in some part and in conjunction with other factors.
本文简要回顾了空气栓塞的一些生理后果，随后讨论了两组连续患者的对比研究结果，第一组是在目前实行的严格常规措施引入之前，第二组是在引入之后。介绍了目前用于预防空气栓塞的技术。
根据脑部紊乱记录估算了520例患者发生全身性空气栓塞的发生率和转归。对两组患者进行了比较，第一组是在严格计划的“除泡”措施引入之前，第二组是在此之后。比较结果显示，近期这组患者中该并发症的发生率和严重程度显著下降。介绍了在特定手术中用于排出空气的技术。讨论了肺空气栓塞。虽然双侧肺不张与肺空气栓塞之间未显示出直接关系，但很有可能过去它至少在一定程度上并与其他因素共同导致了这种情况。
