Despite many advances in the field of lung transplantation, lung transplant recipients have the lowest median survival of any solid organ transplant population. Complications such as reperfusion injury, graft rejection, infection, and anastomotic breakdown increase morbidity and mortality during the immediate postoperative period. Ventilator management with lung protective strategies can not only minimize ventilator time and mitigate the risk of ventilator-associated pneumonia, but it may also decrease the risk of primary graft dysfunction and graft failure. Maintaining fluid balance, pain control, and preserving renal function also decrease postoperative complications. Advancements in immunotherapy with the use of calcineurin inhibitors and monoclonal antibodies have been shown to decrease the incidence of acute rejection. However, when unexpected complications occur, appropriately timed rescue therapies such as the initiation of extra-corporeal membrane oxygenation, retransplantation, and plasmapheresis are important considerations geared toward a positive transplant outcome.
尽管肺移植领域取得了许多进展,但肺移植受者的中位生存期是所有实体器官移植受者中最低的。再灌注损伤、移植物排斥、感染和吻合口破裂等并发症会增加术后即刻的发病率和死亡率。采用肺保护性策略的呼吸机管理不仅可以最大限度地减少呼吸机使用时间,降低呼吸机相关性肺炎的风险,还可能降低原发性移植物功能障碍和移植物衰竭的风险。维持液体平衡、控制疼痛和保护肾功能也可以减少术后并发症。免疫治疗的进展,包括钙调神经磷酸酶抑制剂和单克隆抗体的使用,已被证明可以降低急性排斥反应的发生率。然而,当出现意外并发症时,适时的抢救治疗,如体外膜氧合的启动、再次移植和血浆置换,是实现积极移植结果的重要考虑因素。
