Abstract
Abstract An apparatus for endotracheal intubation comprises a suction stylet telescopically disposed within an endotracheal tube such that the suction stylet is operative to aspirate fluids from the vicinity of the distal end of the endotracheal tube. The apparatus further comprises a connector for releasably axially fixing the suction stylet with respect to the endotracheal tube during intubation. The suction stylet and endotracheal tube are advanced down the trachea simultaneously, the suction stylet aspirating unwanted oral secretions from the operator's field of view during intubation. Once the trachea is intubated, the connector is disconnected and the suction stylet is withdrawn, leaving the endotracheal tube in place. A method for endotracheal intubation is also disclosed in which a suction stylet is telescopically disposed within an endotracheal tube. The suction stylet and endotracheal tube are advanced simultaneously through the trachea, aspirating unwanted secretions from the operator's field of view during the intubation procedure. Upon completion of intubation, the suction stylet is withdrawn, leaving the endotracheal tube in position.
