The rising need for lung transplantation over recent years has not paralleled the availability of suitable lung allografts. The number of lung transplantations performed each year in the United States remains limited by an inadequate supply of suitable donors as well as low donor utilization rates. While several methods have been proposed for increasing the donor pool, there is considerable disparity between acceptance and utilization of these practices among transplant centers. In this review article, we explore various approaches for enhancing donor selection and expanding the donor pool. We discuss the use of "extended criteria" donors including high risk groups such as drug overdose donors, and we examine the role of techniques in donor assessment and selection such as the use of computed tomography for accurate size matching. We review topics in donor management such as the establishment of specialized donor care facilities and the implementation of lung-focused resuscitation protocols, and we discuss advancements in donor procurement such as the utilization of local procurement teams. We also review barriers to donation, such as variability in organ procurement organization (OPO) consent practices, as well as patient-specific factors such as religious or cultural beliefs. Addressing these aspects of donor evaluation, management, and accessibility is essential in maximizing the number of lungs available for transplantation within the existing donor pool.
近年来,肺移植需求的不断上升与合适的肺同种异体移植物的可获得性并不匹配。在美国,每年进行的肺移植数量仍然受到合适供体供应不足以及供体利用率低的限制。虽然已经提出了几种增加供体库的方法,但这些做法在移植中心的接受度和利用率之间存在相当大的差异。在这篇综述文章中,我们探讨了加强供体选择和扩大供体库的各种方法。我们讨论了使用“扩大标准”供体,包括药物过量供体等高风险群体,并研究了诸如使用计算机断层扫描进行精确尺寸匹配等技术在供体评估和选择中的作用。我们回顾了供体管理方面的主题,如建立专门的供体护理设施和实施以肺为重点的复苏方案,并讨论了供体获取方面的进展,如利用当地获取团队。我们还回顾了捐赠的障碍,如器官获取组织(OPO)同意做法的差异,以及患者特定因素,如宗教或文化信仰。解决供体评估、管理和可及性的这些方面对于在现有供体库中最大限度地增加可用于移植的肺数量至关重要。
