Effect of Different Nasotracheal Tubes on Tube Passage

Not Applicable

Completed

• Conditions: Sialolithiasis
• Interventions: Device: nasotracheal tube (Ring-Adair-Elwin); Device: nasotracheal tube (portex)

• Registration Number: NCT04695444
• Lead Sponsor: Gangnam Severance Hospital

Brief Summary

The purpose of the study is to find out the clinical effects that can be obtained during nasotracheal intubation when using velvet-soft PVC tube compared to conventional polyvinylchloride(=PVC) tube.

Detailed Description

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.

Primary Outcome Measures

Name	Time	Method
blockade of tube advancement from the nasal cavity to the oral cavity [ during intubation]	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 Outcome Measures

Name	Time	Method
Intubation time	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
