Singultus is the sudden onset of erratic diaphragmatic and intercostal muscle contraction immediately followed by laryngeal closure. Pathophysiology involves afferent, central and efferent components. Bilateral phrenic nerve block was performed to a 46-year-old woman with a brain tumor with persistent hiccups, with initially positive response but later symptom recurrence. Bilateral pulsed radiofrequency of the phrenic nerve was performed guided by ultrasonography (US). In the follow-up, absence of hiccups was confirmed. The patient was discharged 24 h later. Persistent or untreatable singultus is an infrequent condition that should not be dismissed. This approach is a safe, accurate and effective therapeutic approach for patient's refractory to conservative treatment. Further studies are needed to establish safety and effectiveness of the treatment.
呃逆是一种突然出现的、不规则的膈肌和肋间肌收缩，紧接着是声门关闭。病理生理学涉及传入、中枢和传出成分。我们对一名患有脑瘤且持续打嗝的 46 岁女性实施了双侧膈神经阻滞，最初反应良好，但后来症状复发。我们在超声引导下对双侧膈神经进行了脉冲射频治疗。在随访中，确定患者不再打嗝。24 小时后，患者出院。持续性或难治性呃逆是一种不常见的情况，不应被忽视。对于那些对保守治疗无反应的患者来说，这种方法是一种安全、准确和有效的治疗方法。需要进一步的研究来确定这种治疗方法的安全性和有效性。
