“死亡”的传统概念是心跳和呼吸停止,但随着医学科学的发展,用人工维持呼吸和循环可使一些病例得到挽救或延缓了死亡.通过大量的、反复的临床观察和研究,加上器官移植的开展,对“死亡”的概念有了进一步的认识和转变,提出了新的观念,即“脑死亡”(又称昏迷过度Coma depasse或不可逆昏迷(Irreversible Coma),指全脑功能呈不可逆性丧失,患者虽维持了心跳,但脑功能永不恢复,一定时间内心搏也终必停止.因此如何确定“脑死亡”的标准,以利在“脑死亡”前进行积极的抢救,在“脑死亡”时早期作出正确的判断,在目前更具有重要意义.一、脑死亡的标准 The traditional concept of “death” is heartbeat and respiratory arrest, but with the development of medical science, artificial resuscitation and circulation can save or delay the death of some cases.Through a large number of repeated clinical observations and studies, Coupled with the development of organ transplantation, the concept of “death” has been further recognized and transformed, and new concepts have been proposed, namely “brain death” (also known as Coma depasse or Irreversible Coma) Refers to the loss of irreversible global brain function, although the patient maintained a heartbeat, but the brain function never recovered, heartbeat will eventually stop within a certain period of time.Therefore, how to determine the “brain death” standard, in order to facilitate the “brain death” Before the active rescue, in the “brain death ” early make the right judgments, at the moment more important .A standard of brain death
