Acute carbon monoxide poisoning is a common problem that occurs during winter and leads to serious complications.
We retrospectively studied 24 consecutive cases admitted with the aim of finding the causes and outcome of acute carbon monoxide poisoning.
The source of poisoning was charcoal in 71% of patients, motor gasoline in 21%, and other causes in 8%. Immediate complications included altered consciousness level in 54% of patients, metabolic acidosis in 46%, pneumonia in 42%, cardiac arrhythmia in 29% and rhabdomyolysis in 25%. Late neurological complications occurred in 17% of patients. All the patients received 100% oxygen. Eleven patients (46%) required mechanical ventilation. Ultimately, 19 patients (79%) recovered completely, 4 (17%) had neurological or cardiac disorders, and 1 (4%) died.
Immediate and late complications are common in carbon monoxide poisoning cases admitted to the hospital especially when they arrive late. Time lapse between exposure and presentation may have a role in predicting the outcome.
急性一氧化碳中毒是冬季常见的问题，可导致严重并发症。
我们回顾性研究了连续收治的24例患者，旨在找出急性一氧化碳中毒的原因及预后情况。
71%的患者中毒源为木炭，21%为车用汽油，8%为其他原因。即刻并发症包括54%的患者意识水平改变、46%的患者代谢性酸中毒、42%的患者肺炎、29%的患者心律失常以及25%的患者横纹肌溶解。17%的患者出现迟发性神经并发症。所有患者均接受了100%氧气治疗。11例患者（46%）需要机械通气。最终，19例患者（79%）完全康复，4例（17%）有神经或心脏疾病，1例（4%）死亡。
住院的一氧化碳中毒病例中，即刻和迟发性并发症很常见，尤其是患者就诊较晚时。接触一氧化碳与就诊之间的时间间隔可能对预后有预测作用。
