目的夏季发生的一氧化碳中毒患者中毒原因容易被忽视而导致误诊,特别是老年伴高血压等基础病患者,出现中枢神经损害的症状体征易误诊为急性脑血管病。通过7例误诊原因分析,减少此类病人的误诊误治。方法对7例夏季老年急性一氧化碳中毒误诊急性脑血管病进行误诊分析。结果 7例患者高压氧治疗6痊愈,1例死亡,1例痊愈出院45 d后并发迟发性脑病,再次入院,经高压氧治疗好转出院。结论夏季一氧化碳不常见中毒原因容易被忽视,特别是老年伴高血压等基础病患者,出现中枢神经损害的症状体征易误诊为急性脑血管病,医师应当仔细询问病史,了解发病现场情况,及早血碳氧血红蛋白检测,缩短误诊时间。
The purpose of poisoning in patients with carbon monoxide poisoning in the summer can easily be overlooked and lead to misdiagnosis, especially in elderly patients with underlying diseases such as hypertension, symptoms and signs of central nervous system damage are often misdiagnosed as acute cerebrovascular disease. Through the analysis of 7 cases of misdiagnosis, we can reduce the misdiagnosis and mistreatment of such patients. Methods Misdiagnosis of 7 cases of acute cerebrovascular disease misdiagnosed as acute carbon monoxide poisoning in summer were analyzed. Results In 7 patients, hyperbaric oxygen therapy 6 was cured and 1 patient died. One patient was cured and discharged for 45 days and then had delayed encephalopathy. The patient was admitted again and was discharged after being treated with hyperbaric oxygen. Conclusion The common causes of carbon monoxide poisoning in the summer are easily neglected. Especially in the elderly patients with underlying diseases such as hypertension, symptoms and signs of central nervous system damage are easily misdiagnosed as acute cerebrovascular diseases. Physicians should carefully ask the medical history, understand the scene of the disease, and premature blood Carboxyhemoglobin test, shorten the time of misdiagnosis.
