Misconnected chest tube: An extremely unusual fatal complication of secondary pneumothorax

Abstract

A rare and fatal complication of suction drainage of secondary spontaneous pneumothorax is reported. The patient, likely by a mistake, arbitrarily connected the oxygen supply tube to the thoracic drain. The sharp increase of intrapleural pressure combined with the atmospheric intraalveolar environment caused diffuse lung injury and cardiopulmonary collapse without a direct lung injury. The conflicting interests of patient autonomy and patient safety require further consideration.
