About this study

At King Khalid University hospital approximately 1200-1500 MRI are done yearly on pediatric and neonatal patients. The investigating hospital is one of the pioneers in providing this service in the Kingdom (which was established about 10 years ago) to the patients of this age group. Only a small percentage of pediatric patients with age above 8 years accept the procedure to be done without anesthesia; and majority of MRI procedures are done under general anesthesia. The airway management of these patients is commonly accomplished with laryngeal mask airways (LMA).

LMA are in practice of anesthesia since early 1980s. Pediatric and neonatal patients (including ex-premature) have also been benefited by the use of LMA. There are many advantages of LMA over endotracheal tube (ETT) in pediatric patients like ease of insertion, securing airway rapidly, avoidance of muscle relaxants, reduced incidence of sore throat, post-operative hoarseness and coughing at the time of extubation, greater hemodynamic and intra ocular pressure (IOP) stability.

There are different types of pediatric LMAs available e.g. I-gel, ProSeal, LMA supreme, LMA classic, LMA unique, LarySeal and Ambu. These devices differ morphologically from each other (silicone, polyvinyl chloride or soft gel). Out of all this variety of LMAs only few are MRI compatible (do not produce any artifact in the MRI image), for example Ambu LMA and I-gel LMA and in King Khalid University Hospital (the investigating hospital) these two types are being used.

On search of literature the investigators found only one study in adults in which such comparison has been made and there was no study comparing different LMAs on the basis of their spatial effects on anatomical structures of the neck and airway in pediatric patients with age 12 years or below.

In this prospective randomized study, the investigators will compare the spatial relationship of I-gel Trademark (TM) and Ambu® AuraOnce (AO)TM on pediatric airway in pediatric patients undergoing 3-D MRI under general anesthesia (GA).

I-gelTMActive comparatorI-gel is a supraglottic device made of gel like material. It is used for administration of anesthesia in selected patients.

What is being measured

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

  1. Effect on tongue

    The thickness of the tongue will be defined as the greatest distance between the surface of the tongue and the lower margin of the geniohyoideus muscle measured on sagittal T2 midline images. Scale (mm).

    Measured: After 2 months

Secondary outcomes (5)
  1. Depth of intrusion of the tip of the supraglottic device into the Upper esophageal sphincter

    The depth of insertion relative to the glottis will be defined as the perpendicular distance between a horizontal line through the level of the glottis and a parallel line touching the tip of the supraglottic device on sagittal images. Scale (mm).

    Measured: After 2 months

  2. Effect of Supraglottic devices on hyoid bone

    The position of the hyoid bone relative to cervical spine will be determined by measuring the shortest distance between the dorsal margin of the hyoid bone and the ventral margin of the opposing vertebra body. Scale (mm).

    Measured: After 2months

  3. Effect of Supraglottic devices on glottic area

    The glottic area and the axial diagonal of the glottis will be measured on axial T1 slices at the narrowest part of the glottis after the images has been reoriented to be parallel to the vocal cords and the enclosed glottic area. Scale (mm).

    Measured: After 2 months

  4. Effect of Supraglottic devices on distance between common carotids

    The distance between the common carotids will be defined as the distance between the medial margins of the common carotid arteries measured on the same axial T1 section used to determine the glottic area. Scale (mm).

    Measured: After 2 months

  5. Effect of Supraglottic devices on the distance between the arytenoids

    The distance between the arytenoid cartilages will be measured on an axial T1 plane realigned as described above, with the points of measurement being the most medial part of the vocal process. Scale (mm)

    Measured: After 2 months

Questions about this trial

What is this clinical trial studying?

A study testing I-gel TM and Ambu AuraOnce (AO) in people with Pediatric Laryngeal Mask Airway and Spatial Relations With Pediatric Airway, run by King Saud University at 1 site in Saudi Arabia.

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 5 inclusion and 7 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 27 Feb 2019. 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 Saudi Arabia. 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?

Effect on tongue (time frame: After 2 months). 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 27 Feb 2019.
