Twelve patients who developed hiccup during anaesthesia and surgery were treated successfully with an intravenous injection of ephedrine 5 mg (eleven cases) or 10 mg (one case). In nine patients ephedrine was successful after traditional methods had been tried and failed, and in three patients ephedrine was the only agent given. We conclude that ephedrine is a safe and easy mode of treatment for intractable hiccup during anaesthesia and surgery.
12例在麻醉和手术期间出现呃逆的患者通过静脉注射5毫克麻黄碱（11例）或10毫克麻黄碱（1例）得到成功治疗。9例患者在尝试传统方法失败后使用麻黄碱取得成功，3例患者仅使用了麻黄碱。我们得出结论，麻黄碱是治疗麻醉和手术期间顽固性呃逆的一种安全且简便的方法。
