An interesting complication of the Heimlich manoeuvre.

The removal of inhaled foreign bodies using the Heimlich manoeuvre is recommended as part of the immediate management of the choking child. We report on a case of witnessed laryngeal obstruction by a foreign body in which repeated Heimlich manoeuvres failed to expel the foreign body, but temporarily relieved the obstruction. The repeated Heimlich manoeuvres dislodged the foreign body into the trachea and may have contributed to the rapid development of extensive surgical emphysema, pneumomediastinum and pneumopericardium. The purpose of this report is to demonstrate that the Heimlich manoeuvre was effective in relieving the airway obstruction, but was associated with potentially severe complications.
