We present a rarely described complication of unilateral rhinorrhea and sneezing in a patient who received intravenous sedation with propofol and supplemental oxygen via a nasal cannula during upper gastrointestinal endoscopy. The literature is reviewed and a mechanism is proposed. Mechanical irritation of the nasal mucosa is felt to be the trigger. Suggestions to avoid and to treat are offered.
