Propofol-induced violent coughing in a patient with Becker's muscular dystrophy

Propofol anesthesia is often associated with decreased incidence of gagging, coughing or laryngospasm, and provides intense suppression on airway reflex during tracheal intubation and laryngeal mask airway insertion. Propofol pretreatment is also effective in reducing the occurrence of opioid-induced coughing. These benefits are often attributed to bronchodilator and sedative effects of propofol. However, severe coughing following sedative doses of 1% propofol has not been reported so far. We report a rare case of violent coughing following low-dose propofol infusion in a patient with Becker's muscular dystrophy.
