About this study

The hypothesis of this study is that the velvet-soft PVC tube can advanced from the nasal cavity to the oral cavity through the posterior wall of the pharynx more smoothly than conventional PVC tube, thus reducing blockade of tube advancement, nasal/pharyngeal mucosal bleeding, and intubation time. In addition, investigators would like to compare the technique of nasal intubation using by connecting rubber suction catheter to PVC tube tip.

Treatment and study plan

nasotracheal tube (Ring-Adair-Elwin)

Device

different materials for nasotracheal intubation conventional PVC tube

Other names: nasal RAE (Ring-Adair-Elwin) tube

nasotracheal tube (portex)

Device

different materials for nasotracheal intubation velvet soft PVC tube.

Other names: portex tube

Primary outcomes

  1. blockade of tube advancement from the nasal cavity to the oral cavity [ during intubation]

    Time frame: During nasotracheal intubation (From the time of insertion of the tube through the nostril to completion of the intubation )

    When entering a nasotracheal tube from the nasal cavity to the oral cavity before use of laryngoscope in nasotracheal intubation, clinicians sometimes encounter blockade of in tube advancement. The reason is that the direction of the nasotracheal tube and the posterior wall of the nasopharynx are anatomically perpendicular. When advancing the tube from the nasal cavity to the oral cavity, the researcher will evaluate the presence of blockade of tube advancement in the pharynx. (none / present)

Secondary outcomes

  1. Intubation time

    Time frame: During nasotracheal intubation (From the time of insertion of the tube or tube combined with the rubber suction catheter to the completion of nasotracheal intubation)

    the total time of nasotracheal intubation: From the time of insertion of the tube or tube combined with the rubber suction to the completion of nasotracheal intubation
