为什么尸体会腐烂？如果给尸体加心脏起搏器和正常供氧供血，它会不腐烂吗？ 第1页

不会腐烂。几个高赞答的都不对。

死亡是整体概念，提问者的意思应该是说，有血有氧提供给组织细胞，人体会腐烂吗？

多数高赞套在脑死亡的患者身上，是合理的。

如果心脏也停了，起搏器是不行的，要ECMO，完全可以保障组织细胞血和氧的供应，细胞功能可以完全正常。

补充：这个问题本身就不够严谨，就是个脑洞。“尸体”如果是指明确死亡很久，都出尸斑了那种，组织细胞都已经死亡，那确实不用讨论。

所以大家都在说脑死亡，心脏不跳等，如此即可符合我的回答。

活人身体一样会腐烂，比如下肢坏疽，人可以活得不错，但脚烂了。比如肠坏死，阑尾坏死等等，任何一个或一部分组织，因为血管堵塞或外压等原因导致局部无血供，都会腐烂。

所以，本质是含氧血液供应

日本的病例报告，脑死亡后生命支持165天，心跳停止后宣布死亡，没有进行ECMO支持

国内，今年，应该是有使用ECMO维持很长时间的类似病例，我看到一些新闻报道，但没找到学术报告。

Prolonged Somatic Survival of Clinically Brain-Dead Adult Patient

Jun MARUYA, Keiichi NISHIMAKI, Jun-ichi NAKAHATA, Hiroko SUZUKI, Yasuo FUJITA, Takashi MINAKAWA

A 43-year-old woman suffered clinical brain death after severe head injury. The patient met the criteria for the diagnosis of clinical brain death on Day 3. Aggressive hemodynamic and respiratory managements coupled with triple hormone therapy were performed at the family’s request, resulting in continued cardiac activity for a prolonged period. Spinal reflexes and automatisms were observed until cardiac arrest. Ventilatory support was discontinued on Day 168, when cardiac death was confirmed, and her kidneys and eyeballs were removed for transplantation. The patient survived for 165 days after the diagnosis of clinical brain death, which is an extremely prolonged period of somatic support for an adult patient after brain death. An extensive and informed discussion on the end-of-life treatment of clinically brain-dead patients is urgently required in Japan to establish treatment guidelines for such patients.
