Uncontrolled donation after cardiac death (uDCD) has the potential to ameliorate the shortage of suitable lungs for transplant. To date, no lung transplant data from these donors are available from North America. We describe the successful use of these donors using a simple method of in situ lung inflation so that the organ can be protected from warm ischemic injury. Forty-four potential donors were approached, and family consent was obtained in 30 cases (68%). Of these, the lung transplant team evaluated 16 uDCDs on site, and 14 were considered for transplant pending ex vivo lung perfusion assessment. Five lungs were ultimately used for transplant (16.7% use rate from consented donors). The mean warm ischemic time was 2.8 hours. No primary graft dysfunction grade 3 was observed at 24, 48, or 72 hours after transplant. Median intensive care unit stay was 5 days (range: 2-78 days), and median hospital stay was 17 days (range: 8-100 days). The 30-day mortality was 0%. Four of 5 patients are alive at a median of 651 days (range: 121-1254 days) with preserved lung function. This study demonstrates the proof of concept and the potential for uDCD lung donation using a simple donor intervention.
心脏死亡后非控制捐献(uDCD)有可能缓解适合移植的肺源短缺问题。迄今为止,北美尚无来自这些供体的肺移植数据。我们描述了一种通过简单的原位肺膨胀方法成功利用这些供体的情况,以便保护器官免受热缺血损伤。我们联系了44名潜在供体,30例(68%)获得了家属同意。其中,肺移植团队对16例uDCD进行了现场评估,14例在等待体外肺灌注评估时被考虑用于移植。最终5个肺用于移植(同意捐献者的利用率为16.7%)。平均热缺血时间为2.8小时。移植后24、48或72小时未观察到3级原发性移植物功能障碍。重症监护病房中位住院时间为5天(范围:2 - 78天),医院中位住院时间为17天(范围:8 - 100天)。30天死亡率为0%。5例患者中有4例存活,中位时间为651天(范围:121 - 1254天),肺功能良好。这项研究证明了概念的可行性以及通过简单的供体干预进行uDCD肺捐献的潜力。
