Two fatal and five non-fatal episodes of air embolism occurred in the course of 14,000 haemodialyses. Air entered the circuit through the infusion bottle, the heparin syringe or line, or the blood pump insert. Emergency treatment with posture, oxygen, dextran infusion, and dexamethasone was apparently successful in reversing some of the manifestations. Prevention depends partly on better design of equipment and partly on the incorporation in the haemodialysis circuit of devices which detect air and prevent it from reaching the patient. Such monitors are not in general use in the United Kingdom and those currently available are far from infallible. We describe an alternative system incorporating a floating valve in the bubble trap.
在14000次血液透析过程中发生了2起致命和5起非致命空气栓塞事件。空气通过输液瓶、肝素注射器或管路，或血泵插管进入循环系统。采用体位、吸氧、输注右旋糖酐和地塞米松进行的紧急治疗在逆转部分症状方面显然取得了成功。预防部分取决于设备的更好设计，部分取决于在血液透析回路中加入检测空气并防止其进入患者体内的装置。这种监测器在英国尚未普遍使用，目前可用的监测器也远非万无一失。我们描述了一种在气泡捕捉器中装有浮阀的替代系统。
