摘要急性一氧化碳中毒可造成全身多脏器缺氧性损伤，神经功能损害和心脏功能障碍是重症中毒患者常见表现，但出血性并发症在临床上较为少见。本文报道1例急性重度一氧化碳中毒继发腹直肌鞘内巨大血肿患者的临床诊治经过，分析急性重度一氧化碳中毒继发腹直肌鞘内血肿的病理生理机制及救治策略，以提高对一氧化碳中毒出血性并发症的认识。该病例提示，对于既往已存在心血管系统疾病史及服用抗凝药物的患者，临床医生在制定治疗方案时，需警惕出血的风险。

abstractsAcute carbon monoxide poisoning can cause hypoxic injury to multiple organs. Neurological impairment and cardiac dysfunction are common manifestations of severe poisoning patients, but hemorrhagic complications are rare in clinic. The clinical diagnosis and treatment of a case of massive intrathecal hematoma of the rectus abdominis secondary to acute severe carbon monoxide poisoning was reported. The pathophysiological mechanism and treatment strategy of rectus sheath hematoma secondary to acute severe carbon monoxide poisoning was analyzed, in order to improve the understanding of hemorrhagic complications of carbon monoxide poisoning. This case suggests that for patients with a history of cardiovascular disease and taking anticoagulants, clinicians should be alert for the risk of bleeding when making medical decisions.
