A 34-year-old Sri Lankan man presented with multiple episodes of vomiting following accidental ingestion of 100 ml of indoxacarb (Avaunt). He had a significant saturation gap (discrepancy between oxygen saturation [98%] in blood gas analysis and saturation on pulse oximetry [70%] in finger pulse oximetry), the color of the blood was muddy brown, and the methemoglobin level (60%) was high in the blood gas analysis. A diagnosis of methemoglobinemia secondary to indoxacarb poisoning was made, and he was treated with methylene blue with a favorable outcome. Methemoglobinemia secondary to indoxacarb poisoning is extremely rare, and clinicians should be aware of this important complication. Methemoglobinemia secondary to indoxacarb poisoning has a favorable outcome if recognized and treated promptly.
一名34岁的斯里兰卡男子在意外摄入100毫升茚虫威（安打）后出现多次呕吐。他存在明显的血氧饱和度差值（血气分析中的血氧饱和度[98%]与手指脉搏血氧饱和度测定仪上的血氧饱和度[70%]之间的差异），血液颜色呈泥褐色，血气分析中的高铁血红蛋白水平较高（60%）。诊断为茚虫威中毒继发高铁血红蛋白血症，给予亚甲蓝治疗后效果良好。茚虫威中毒继发高铁血红蛋白血症极为罕见，临床医生应意识到这一重要并发症。茚虫威中毒继发高铁血红蛋白血症若能及时识别并治疗，预后良好。
