众所周知,高原环境中脑和肺是两个极易受累脏器,其机理尚未阐明,问题在于高原脑水肿是由于肺摄氧不足导致脑缺氧,这是由于脑微循环障碍或其它原因造成还未确定。由于高原同时存在着缺氧和微循环障碍这两个因素,因此本文就这二种因素对脑水肿形成方面所起作用进行简略论述。一、缺氧的影响尽管对继发于局部或全脑缺血所致的脑水肿已进行了广泛地探讨,也明确了其病理本质,但如果只有缺氧而无缺血是否可造成脑水肿还不清楚。Ba- It is well-known that brain and lung are two highly vulnerable organs in the plateau environment. The mechanism has not been elucidated yet. The problem is that cerebral edema in the plateau is caused by lack of oxygenation of the lung, which is caused by cerebral microcirculation disorder or other reasons Not sure. Due to the simultaneous presence of hypoxia and microcirculation in the plateau, this article briefly discusses the role these two factors play in the formation of cerebral edema. First, the impact of hypoxia Although secondary to local or global cerebral ischemia caused by cerebral edema has been extensively explored, but also clear the pathological nature, but if only hypoxia without ischemia can cause cerebral edema Still not clear.
