The use of extracorporeal membrane oxygenation (ECMO) for elective thoracic surgical procedures has been infrequently reported in the anaesthetic literature. We report the use of intraoperative veno-venous ECMO support for a patient with a previous left pneumonectomy who required a right-sided thoracotomy for repair of a tracheo-oesophageal fistula. To avoid traumatising or pressurising the fistula, a spontaneous ventilation technique was used prior to intubation with a single-lumen endotracheal tube positioned above the level of the fistula. The ECMO cannulas were inserted after induction and ECMO was instituted prior to transfer to the lateral position. Oxygenation during ECMO was augmented with apnoeic oxygen delivery via the breathing circuit. This was associated with an increase in the oxygen saturations from 80% to 99% without compromising surgical access. The use of apnoeic oxygenation via the breathing circuit significantly improved gas exchange in this case and should be considered as an adjunct to veno-venous ECMO.
体外膜肺氧合(ECMO)用于择期胸外科手术的情况在麻醉学文献中鲜有报道。我们报告了一例曾行左肺切除术的患者,因气管食管瘘修补需要行右侧开胸手术,术中使用静脉-静脉ECMO支持。为避免损伤或压迫瘘口,在插管前采用自主通气技术,使用单腔气管内导管置于瘘口水平上方。诱导后插入ECMO插管,并在转至侧卧位前启动ECMO。ECMO期间通过呼吸回路进行无呼吸氧输送以增强氧合。这使得氧饱和度从80%提高到99%,同时不影响手术操作。在该病例中,通过呼吸回路进行无呼吸氧合显著改善了气体交换,应被视为静脉-静脉ECMO的辅助手段。
