[Use of Parker Flex-Tip tracheal tube in a patient with Kniest dysplasia].

A 37-year-old man with Kniest dysplasia and thoracic myelopathy was scheduled for T3-12 laminectomy. Kniest dysplasia is a severe chondrodysplasia characterized by short trunk and limbs. Awake fiberoptic intubation was attempted to prevent airway obstruction because we had predicted his difficult airway. During fiberoptic tracheal intubation, we easily succeeded in the insertion of the fiberscope itself into the trachea, but were not able to insert the tip of a reinforced tube into the trachea, because the tip of the reinforced tube impinged on laryngeal structures. We succeeded in placing the Parker Flex-Tip tracheal tube into the trachea. We considered that the Parker Flex-Tip tube, having a tip that reduces the gap between the fiberscope and the inside of the tube, resulted in success of the passage of the tube into the trachea during fiberoptic intubation.
