A Clinical Analysis of Hiccup Patients who Visited the Emergency Department

ABSTRACT

PURPOSE: There have been few studies concerned with the hiccup patients who visit the emergency department. The purpose of this study is to investigate the epidemiology and clinical characteristics of hiccup patients. METHODS: We retrospectively reviewed 60 hiccup patients who visited the emergency departments of Chungbuk National University Hospitals, Chungnam National University Hospital and Chonnam National University Hospital in Korea from January 2005 to December 2007. We categorized the patients into 2 groups of the discharged and the admitted and also into groups of patients who had different types of treatments. We compared clinical outcomes and characteristics of the groups. RESULTS: A total of 60 cases of hiccup patients visited the emergency department from January 2005 to December 2007. There was a significant difference in the recovery rate from hiccups between the discharged group and the admission group (72.4% & 100.0%, p=0.04). The 3 major drugs used for treatment were metoclopramide, chlorpromazine, and benzodiazepine. The patients showed a broad spectrum for the final diagnosis, from the benign hiccups to ischemic stroke in the pons area. CONCLUSION: In this study, the hiccup patients who visited the ED showed simple temporal signs to various severe diseases such as the ischemic stroke in the pons. These findings can be useful reference for the decision making at admission or discharge and for predicting the prognosis of the hiccup patients who visit the emergency department.
