About this study

Official title: Comparison of Sliding Technique and Conventional Technique for Videolaryngoscopy in Patients Undergoing Cervical Spine Surgery With Semi-rigid Neck Collar During Intubation

In the case of tracheal intubation using a video laryngoscope, both techniques, one is 'conventional technique' in which intubation is performed by placing the blade tip on the vallecula and the other is 'sliding technique' performed by sliding the blade under the epiglottis, are commonly conducted by anesthesiologists. Investigators would like to compare if the sliding technique can improve the condition of tracheal intubation in patients wearing semi-rigid neck collars in cervical spine surgery.

Read the detailed description

For patients who need to limit the movement of the cervical spine, the tracheal intubation becomes difficult because the head must be positioned in the neutral position. Most of all, with a semi-rigid neck collar that maintains the neutral position of the head and neck, movement is limited and the mouth is not well-opened make the environment of tracheal intubation worse, which result in hypoxia or throat complications related to general anesthesia. Fortunately, it is possible that the development of video laryngoscope assists tracheal intubation easier for patients who have the limited movement of the cervical spine. However, the preferred intubation style and instrument selection for each operator are varied; the established method is required. In the case of tracheal intubation using a video laryngoscope, both techniques, one is 'conventional technique' in which intubation is performed by placing the blade tip on the vallecula and the other is 'sliding technique' performed by sliding the blade under the epiglottis, are commonly conducted by anesthesiologists. Investigators would like to compare if the sliding technique can improve the condition of tracheal intubation in patients wearing semi-rigid neck collars in cervical spine surgery.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sliding Intubating TechniqueProcedure or surgery

    Sliding technique' means that endotracheal intubation is performed by sliding the videolayngoscope blade under the epiglottis smoothly.

Study groupRoleWhat they receive
Conventional Intubating TechniqueNo intervention'Conventional technique' means that endotracheal intubation is performed with the videolayngoscope blade lifting up the epiglottis.
Sliding Intubating TechniqueExperimental'Sliding technique' means that endotracheal intubation is performed by sliding the videolayngoscope blade under the epiglottis smoothly.
Receives: Procedure: Sliding Intubating Technique

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. percentage of glottic opening (POGO) score (%)

    The POGO score represents the percentage of glottic opening seen, defined by the linear span from the anterior commisure to the interarytenoid notch.

    Measured: When we insert the endotracheal tube during anesthetic induction

Questions about this trial

What is this clinical trial studying?

A study testing Sliding Intubating Technique in people with Cervical Spine Surgery and Intubation;Difficult, run by Gangnam Severance Hospital at 1 site in South Korea.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 May 2022. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in South Korea. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

percentage of glottic opening (POGO) score (%) (time frame: When we insert the endotracheal tube during anesthetic induction). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 May 2022; AzTrials last refreshed its copy on 31 Oct 2026.
