title: A hazard of the pollard endotracheal tube.
abstract: Two patients are described in whom failure of the Pollard endotracheal tube produced complete respiratory obstruction. Comparisons are made of external diameters, resistance to gas flow and resistance to compression between Pollard tubes and several conventional tubes. It is concluded that the Pollard tube is not satisfactory for microlaryngoscopy.
