通过报道1例急性一氧化碳中毒致迟发性脑病的临床表现、诊断及治疗经过,分析了一氧化碳中毒致迟发性脑病的发生率与一氧化碳中毒时的严重程度有时不一致,提示脑CT异常发生较晚,脑电图及脑干诱发电位异常发生较早,中毒初期应采取及时有效的治疗措施。对脑电图及脑干诱发电位异常者,常提示有迟发性脑病发生的可能,要做好定期随访。 The clinical manifestations, diagnosis and treatment of delayed encephalopathy caused by acute carbon monoxide poisoning were reported. The incidence of delayed encephalopathy caused by carbon monoxide poisoning was sometimes inconsistent with the severity of carbon monoxide poisoning, suggesting a later occurrence of abnormal brain CT , EEG and brainstem evoked potential anomalies occurred earlier, early poisoning should take timely and effective treatment. Of the EEG and brainstem abnormalities, often prompted the possibility of delayed encephalopathy, to be regular follow-up.
