經肛門灌腸的甲醇中毒：病例報告

Enema-Induced Methanol Intoxication: A Case Report

甲醇中毒多由口食入，我們在此報告一例少見的經由灌腸而甲醇中毒的案例，一位62 歲女性因誤聽他人告知甲醇灌腸可解決便秘問題，故自行以空的甘油浣腸球吸入甲醇灌腸，後來因急性腹痛到急診就醫，數小時後意識不清，由於甲醇中毒導致嚴重酸中毒病人接受插管呼吸、血液透析與加護病房照顧，住院期間曾併發肺炎再入加護病房，歷經30 天後來平安出院，但仍有視力模糊的後遺症。自行灌腸可導致併發症，甲醇可經由灌腸而直腸吸收導致中毒。

Most methanol intoxication occurs after oral ingestion. We report a rare case of enemainduced methanol intoxication. A 62-year-old woman was told a methanol enema could resolve constipation, so she tried an enema with a methanol-containing glycerin ball. She came to our emergency department because of acute abdominal pain. Several hours later she became unconscious. She was intubated, placed on hemodialysis and admitted to the intensive care unit (ICU) because of severe acidosis resulting from methanol intoxication. The blood methanol was 166 mg/dL. Pneumonia developed during hospitalization and she was readmitted to the ICU. She was discharged smoothly after 30 days hospitalization with the sequela of blurred vision. Enemas can induce complications and methanol intoxication can be induced by an enema.
