Extracorporeal membrane oxygenation (ECMO) is used as the last resort for primary graft dysfunction (PGD). The aim of this study is to explore the predictors and outcomes for early mortality in postlung transplant patients who required ECMO for PGD. Between January 2006 and December 2015, 1,049 cases of lung transplantation were performed at our center. Ninety-six patients required ECMO support after lung transplantation, 52 patients (54%) had PGD. Seven patients (13.5%) required venoarterial ECMO due to concomitant hemodynamical instability, and the others required venovenous ECMO. The patients were on ECMO for 5.00 ± 10.6 days. Forty-four patients (84.6%) were successfully decannulated. The 90 day, 1 year, and 5 year survival of patients who required ECMO for PGD after lung transplantation were 67.3%, 50.0%, and 31.5%, respectively. Cox regression indicated that when the patient was placed on ECMO later than 48 hours after transplantation, the patient could have higher in-house mortality (hazard ratio, 2.79; 95% CI, 1.21-6.43) and also higher 3 year mortality (hazard ratio, 2.30; 95% CI, 1.13-4.68) regardless of the patients' preoperative conditions or complexity of lung transplantation. Earlier recognition of PGD and initiation of ECMO may be beneficial in this population.
体外膜肺氧合(ECMO)被用作原发性移植物功能障碍(PGD)的最后手段。本研究旨在探讨需要 ECMO 治疗 PGD 的肺移植后患者早期死亡的预测因素和结果。2006 年 1 月至 2015 年 12 月,本中心共进行了 1049 例肺移植。96 例肺移植后需要 ECMO 支持,52 例(54%)有 PGD。由于同时存在血流动力学不稳定,7 例(13.5%)需要静脉-动脉 ECMO,其余患者需要静脉-静脉 ECMO。患者接受 ECMO 治疗 5.00±10.6 天。44 例(84.6%)患者成功脱机。需要 ECMO 治疗 PGD 的患者在肺移植后 90 天、1 年和 5 年的存活率分别为 67.3%、50.0%和 31.5%。Cox 回归表明,当患者在移植后 48 小时后才开始使用 ECMO 时,患者的院内死亡率(风险比,2.79;95%可信区间,1.21-6.43)和 3 年死亡率(风险比,2.30;95%可信区间,1.13-4.68)都更高,而与患者术前情况或肺移植的复杂性无关。更早地识别 PGD 并开始使用 ECMO 可能对这一人群有益。
