颅脑手术原来也会引起脑出血,真是无奇不有

颅脑手术会引起胃出血,这是真的吗? 真的!!! 脑袋和胃离得挺远的,怎么会这样?不会是人为的吧? 患者及其家属经常会质问这样的问题。事实上,这就是颅脑手术的并发症,而且是比较常见的现象,绝不是人为!!! 医学上将这种胃出血称为“应激性溃疡”。应激性溃疡泛指休克、创伤、手术后和严重全身性感染时发生的急性胃炎,多伴有出血症状,是一种急性胃黏膜病变。 我不太理解“应激”。应激的英文是“stress”,在机械物理学上,该词译为“压力”;而在生物学或心理学领域,该词译为“应激”。有机体在生理或心理上受到威胁时,引起机体与刺激直接相关的特异性变化外,还引起一系列与刺激性质无关的非特异性适应反应。 那么,人类什么都吃,感觉胃是人体最强大的器官,为什么这么脆弱?为什么会发生溃疡出血? 胃是应激状态下最为敏感的器官,情绪可抑制胃酸分泌和胃蠕动,紧张和焦虑可引起胃黏膜糜烂。 颅脑手术会让我们最强大的”胃“产生巨大的压力,这和溃疡、出血有什么关系? 大脑中有两个部位很重要:丘脑和下丘脑。这个地方受到影响,就会导致胃液分泌的增加,胃蠕动增强,胃的肌张力增高,最终将导致胃的终末血管的痉挛。其直接结果就是胃粘膜缺
