Combined Korean Medicine Treatment of a Patient Diagnosed with Posterior Limb of Internal Capsule Infarction Presenting with Hiccups as the Chief Complaint - A Case Report

Objective: Hiccup is a sudden, involuntary contraction of the diaphragm and intercostal muscles, followed by laryngeal closure. Persistent hiccups can occur in the central nervous system following a cerebral infarction. While medications, for example chlorpromazine, are commonly used for treatment, they often fail to fully resolve the hiccups, showing little to no improvement in symptoms. The aim of this study was to present the treatment response of a patient diagnosed with posterior limb of internal capsule (PLIC) infarction, who was experiencing hiccups and was treated with combined Korean medicine after taking chlorpromazine.Case Presentation: A 71-year-old male diagnosed with left PLIC infarction was experiencing problems in daily life due to hiccups and dysarthria. During the 10-day hospitalization, he received treatment that included herbal medicine (modified <i>Hyeolbuchugeo-tang</i>, Xiěfǔzhúyūtāng), acupuncture (GV20, LI11, ST36, LI4, LR3, and submandibular area acupoint), moxibustion, cupping, and physical therapy. After 10 days of hospitalization, the patient’s hiccups disappeared, and he did not have to take any chlorpromazine. The score on the Numerical Rating Scale fell from 7-8 to 1-2. The 5-level EQ-5D version (EQ-5D-5L) fell from 11 to 7, and the EQ Visual Analogue Scale (EQ-VAS) rose from 20 to 80. The frequency (times per minute) of hiccups decreased and almost disappeared. During outpatient treatment, the patient stated that he did not experience hiccups for 7 months, and no significant side effects were observed.Conclusion: This study suggests that a patient with hiccups as a chief complaint can be effectively treated with combined Korean medicine. However, more studies with control groups are needed to confirm these findings.
