Abstract

Maintaining a brain stem-dead (BSD) donor is specialized science. It is a daunting task as they are fragile patients who need to be handled with utmost care owing to extreme haemodynamically instability and need the best of monitoring for maintenance of organs. To ensure a successful transplant, a BSD donor first needs to be identified on time. This requires scrupulous monitoring of neurologically compromised patients who tend to be the most frequent organ donors. Once the donor is identified, an all-out effort should be made to legally obtain consent for the donation. This may require numerous sessions of counselling of the relatives. It needs to be performed tactfully, displaying the best of intentions. It is important to understand the physiology of a brain-dead individual. A cascade of changes occurs in BSD donor which result in a catastrophic plummeting of the clinical condition of the donor. All organ systems are involved in this clinical chaos, and best possible clinical support of all organ systems should be available and extended to the donor. Organ support includes cardiovascular, pulmonary, temperature, glycaemic, metabolic and hormonal. This article has been written as a follow-up article of previously published article on identifying an organ donor. It intends to give the reader a concept of what the BSD donor undergoes after brain death and as to how to maintain and preserve various organs for donation for successful transplantation of maximum organs.

摘要

维持脑死亡(BSD)供体是一门专业科学。这是一项艰巨的任务,因为他们是脆弱的患者,由于血流动力学极度不稳定,需要极其小心地处理,并且需要最好的监测以维持器官功能。为确保移植成功,首先需要及时识别出BSD供体。这需要对神经功能受损的患者进行仔细监测,这些患者往往是最常见的器官供体。一旦确定了供体,就应全力以赴合法获得捐赠同意。这可能需要对亲属进行多次咨询。需要巧妙地进行,展现出最好的意图。了解脑死亡个体的生理状况很重要。BSD供体中会发生一系列变化,导致供体临床状况急剧下降。所有器官系统都参与到这种临床混乱中,应向供体提供并扩展所有器官系统尽可能好的临床支持。器官支持包括心血管、肺部、体温、血糖、代谢和激素方面的支持。本文是之前发表的关于识别器官供体文章的后续文章。它旨在让读者了解BSD供体在脑死亡后所经历的情况,以及如何维护和保存各种器官以供捐赠,从而成功移植尽可能多的器官。
