Commonly, nasogastric tubes (like all nasoenteric tubes) are inserted blindly. Malposition is seen in anything from 0.5 to 16% cases. Incorrect positioning may include tracheal, bronchial or pleural spaces, with potential sequelae of infusion of feed into the lung/pleural cavity, pneumothorax or lung abscess. Traditional methods of checking tube position, e.g. air via tube and auscultation are notoriously inaccurate and must not be relied upon. Radiographic validation is the best way if any doubt exists ¹.
