[Pediatric airway management : cuffed endotracheal tube and other devices for tracheal intubation].
Uncuffed endotracheal tubes have been commonly used in pediatric patients, but cuffed pediatric endotracheal tubes are recently introduced and stirred up a controversy. Uncuffed tubes may require multiple laryngoscopies, pollute the environment, and cause pulmonary aspiration as well as unstable ventilation. A recent study revealed that the contours of the airway and the tracheal tube are different, so that the pressure exerted on some parts of the cricoid mucosa may not be appropriate. Cuffed endotracheal tubes overcome these shortcomings if anesthesiologists pay close attention to the insertion length of the tube and cuff pressure. Laryngeal mask airway has worked well, with few complications, as a ventilatory device in pediatric patients whose tracheas cannot be intubated and/or whose lungs cannot be ventilated with conventional techniques. It is also used for a conduit for fiberoptic intubation and emergent airway with patients in the prone position. The lightwand (Trachlight) is another device for pediatric intubation and is recommended as the first-line option in patients who can be ventilated but in whom laryngoscopic intubation has failed. AirWayScope (Pentax-AWS) is a novel intubation device which combines an airway, camera and monitor It can be an epoch-making intubation device for infants and children if a smaller size is available in the future.
