脑循环障碍与急性CO中毒迟发性脑病

Cerebral circulation obstacle and delayed encephalopathy after acute carbon monoxide poisoning

脑循环血液供应是保证脑组织正常新陈代谢的前提条件,任何原因所造成的脑循环阻力增加、血流速度缓慢均会影响神经系统的正常功能。CO中毒迟发性脑病是以痴呆、智力障碍为主要表现的精神症状,且好发于老年,尤其合并有高血压、动脉粥样硬化的患者,提示脑循环障碍与急性CO中毒迟发性脑病可能存在必然的联系。

Blood supply of cerebral circulation is the basis of normal metabolism of brain tissue,any reason such as increased blood flow resistance,slow blood flow may affect normal function of nervous system. Delayed encephalopathy after acute carbon monoxide poisoning（DEACMP） is one of spirit complication including dementia,mental retardation,and so on. The severe complication happens more often in the elder with hypertension or atherosclerosis. All these suggest there may be necessary link between cerebral circulation obstacle and delayed neuropsychiatric sequelae.
