Cuff Inflation-supplemented Videoscope-guided Nasal Intubation

Status Recruiting

Clinical Trial Summary

Epistaxis or post-pharyngeal bleeding is the most common complication after nasotracheal intubation (NTI). Prior thermal softening of the endotracheal tube (ET) has been recommended as one of the methods to prevent nasal trauma from nasotracheal intubation. However, thermal softening of tubes tends to adversely affect the nasotracheal navigation of the ET.

During NTI under conventional direct laryngoscopy, the tip of the Macintosh laryngoscope is advanced into the vallecula, indirectly elevating the epiglottis by applying pressure on the hyoepiglottic ligament. Although this maneuver allows optimal visualization of the glottis, it lifts the larynx away from the tip of the advancing nasotracheal tube (NTT), which generally lies along the posterior pharyngeal wall. Most clinicians use Magill forceps to direct the tip of the NTT anteriorly to enter the glottis. Magill forceps may cause damage to the cuff of an ET or may injure oropharyngeal mucosa.

The use of a video laryngoscope and a cuff inflation technique has been proposed as a method for reducing the malalignment of tubes. Indirect laryngoscopy using a Video laryngoscopy can reduce malalignment by minimizing lifting the glottis during laryngoscopy. The cuff inflation technique (wherein the cuff of ET tube is inflated with 15 mL of air) has been used while performing "blind" NTI to guide such malaligned polyvinyl chloride (PVC) ET tubes into the laryngeal inlet. Recently, one study reported that the cuff inflation technique consistently improved the oropharyngeal insertion of the different ET tubes of varying stiffness during direct laryngoscope-guided NTI.

There has never been study about effect of cuff inflation technique on navigability when performing NTI under video laryngoscopy guidance with ET tubes of varying stiffness.Investigators assessed and compared the incidence of nasal injury and nasotracheal navigability with two technique during cuff inflation-supplemented NTI guided by video- laryngoscopy

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
