Abstract
- Hiccup is characterized by a myoclonus in the diaphragm, resulting in a sudden inspiration associated with an audible closure of the glottis. The reflex arc in hiccups comprises three pars. an afferent, a central and an efferent part. The afferent portion of the neural pathway of hiccup formation is composed of the vagus nerve, the phrenic nerve, and the sympathetic chain arising from T6 to Tl2. The hiccup center is localised in the brain stem and the efferent limb comprises phrenic pathways. All stimuli affecting the above mentioned reflex arc may produce hiccups. The pathogenesis of persistent hiccups is not known. Hiccup can present a symptom of a subphrenic abscess or gastric distention, and metabolic alterations may also cause hiccups. Numerous treatment modalities have been tried but with questionable success We describe a patient whose persistant hiccups was treated successfully by a cervical epidural block.
