Blind nasoenteric intubation was attempted in a patient with chronic parkinsonism. The tube was inadvertently misplaced and penetrated the left pleural cavity. The next day, the patient developed cardiopulmonary arrest during dietary supplement infusion. This complication ultimately led to the patient's death. We have reviewed the known complications of nasoenteric tube placement and conclude that difficult insertion in patients at risk from tube misplacement should be followed by chest radiography to confirm the correct placement of the tube before nutritional support is started.
