Methylene blue is used to check tubal patency during laparoscopy. We report the case of a 28-year-old patient who presented a blue coloring of the skin, mucous membranes and nails after methylene blue test during laparoscopy for infertility. The oxygen saturation was 82%. The patient was hospitalized for 48 hours in the intensive care unit and spectrophotometric analysis revealed a methemoglobin level of 8.9%, thus confirming the diagnosis of methemoglobinemia. The suites were simple with normalization of the saturation. It is important to know the complications of the injection of methylene blue in order to prevent them and ensure adequate monitoring for the patients.
亚甲蓝用于在腹腔镜检查期间检查输卵管通畅性。我们报告了一例 28 岁患者的病例，该患者在腹腔镜检查因不孕而进行的亚甲蓝试验后出现皮肤、粘膜和指甲呈蓝色。血氧饱和度为 82%。患者在重症监护病房住院 48 小时，分光光度分析显示高铁血红蛋白水平为 8.9%，从而确诊为高铁血红蛋白血症。套房很简单，饱和度正常。了解亚甲蓝注射的并发症非常重要，以便预防这些并发症并确保对患者进行充分监测。
