Tracheostomy is recommended in case of prolonged mechanical ventilation. Therefore, most patients with an indication for venovenous extracorporeal membrane oxygenation (ECMO) will also have an indication for tracheostomy.
We report 2 cases of fatal air embolism into the ECMO system as complication of percutaneous dilatational tracheostomy. Both patients had an AVALON ELITE® bi-caval cannula implanted draining blood from the vena cava superior and inferior.
Since there is limited safety data on this specific group of patients, a routine early dilatational tracheostomy might be associated with a significant risk.
对于长时间机械通气的情况，建议进行气管切开术。因此，大多数有静脉-静脉体外膜肺氧合（ECMO）指征的患者也有气管切开术的指征。
我们报告2例经皮扩张气管切开术并发症导致致命空气栓塞进入ECMO系统的病例。两名患者均植入了AVALON ELITE®双腔插管，用于引流上、下腔静脉的血液。
由于关于这一特定患者群体的安全数据有限，常规早期扩张气管切开术可能存在重大风险。
