The shortage of organ donors remains a major problem for transplantation worldwide. Potential donors after brain death may become hemodynamically unstable, despite maximal medical management, which ultimately leads to failure of organ procurement. We reviewed the medical records of five brain-dead potential donors who presented with hemodynamic instability despite maximal medical management that were supported by extracorporeal circulation membrane oxygenation (ECMO). The outcomes of heart recipients were reviewed. The five donors under extracorporeal support finished a declaration of brain death without cardiac arrest. Donor organs, including three hearts, nine kidneys, and four livers, were harvested from the five donors under ECMO support. All three heart recipients recovered uneventfully after one yr of follow-up. Our experience indicates that potential donors may experience central-failure-related hemodynamic instability after brain death, despite maximal medical support, which leads to a fatal result. Beyond medical management, prompt and early extracorporeal support for salvaging brain-dead potential donors from cardiac death seems to be a practical strategy to increase the donor pool and preserve donor organs.
器官捐献者的短缺仍然是全球移植领域的一个主要问题。尽管进行了最大限度的医疗管理,潜在的脑死亡后供体仍可能出现血流动力学不稳定,最终导致器官获取失败。我们回顾了五例脑死亡潜在供体的病历,这些供体尽管进行了最大限度的医疗管理,但仍存在血流动力学不稳定,并接受了体外膜氧合(ECMO)支持。我们还回顾了心脏受者的结局。在体外支持下的五名供体在没有心脏骤停的情况下完成了脑死亡的宣告。在 ECMO 支持下,从五名供体中采集了包括三个心脏、九个肾脏和四个肝脏在内的供体器官。所有三名心脏受者在随访 1 年后均恢复良好,无并发症。我们的经验表明,尽管进行了最大限度的医疗管理,潜在的供体在脑死亡后仍可能出现与中枢衰竭相关的血流动力学不稳定,导致致命后果。除了医疗管理之外,及时、早期地对脑死亡潜在供体进行体外支持以避免心源性死亡,似乎是增加供体库和保存供体器官的一种实用策略。
