Carbon monoxide (CO) is an odorless and colorless gas that is formed by the combustion of hydrocarbon. CO poisoning is not an uncommon phenomenon that can have serious consequences for morbidity and mortality. The most frequent causes of accidental poisoning include smoke inhalation from fires, malfunctioning heating devices, smoke from motor vehicles in a poorly ventilated or enclosed space, and electrical cable fires. CO has a higher affinity to hemoglobin than oxygen leading to the formation of carboxyhemoglobin. It impairs the oxygen transport and cytochrome chain which, therefore, leads to further cellular and immunological changes. Here, we present a case of CO poisoning resulting in combined cardiac and neuropsychiatric complications.
一氧化碳(CO)是一种无色无味的气体,由碳氢化合物燃烧产生。一氧化碳中毒并非罕见现象,可能对发病率和死亡率产生严重影响。意外中毒最常见的原因包括火灾烟雾吸入、加热设备故障、通风不良或封闭空间内机动车尾气、电缆火灾。一氧化碳与血红蛋白的亲和力高于氧气,导致形成碳氧血红蛋白。它会损害氧气运输和细胞色素链,进而导致进一步的细胞和免疫变化。在此,我们报告一例一氧化碳中毒导致心脏和神经精神并发症的病例。
