|Abstract:||We have analysed the clinical manifestations of nine patients with brief upper airway dysfunction (BUAD) who attended the thoracic department of a major teaching hospital between 1987 and 1991. Episodes of BUAD developed within 1-4 months of presentation in three patients but were undiagnosed for 2.5-12.5 years in six. The mean age at onset was 51 years ranging from 37 to 66 years. The episodes occurred at irregular intervals. They lasted approximately 1-5 min, were frightening and consisted of an initial phase of obstructive apneoa lasting a few seconds to 2 min and a second phase of respiratory distress with inspiratory stridor lasting 1-4 min. Daytime episodes occurred in all and at night in five, waking three of the patients from sleep. In most instances, throat irritability triggered the episodes which were often preceded by cough. Potential causes of throat irritability included respiratory tract infection, allergy, oesophageal reflux and obstructive sleep apnoea. After treatment of throat irritability BUAD has ceased for at least a year in six of the eight with adequate follow-up. In conclusion, BUAD has characteristics clinical features which should enable it to be recognized more frequently, ensuring successful management.|
