Plain English summary of protocol

Background and study aims
Children require deep sedation when undergoing magnetic resonance imaging (MRI) scans. General anesthetics such as propofol cause airway narrowing and, in some cases, complete blockage of the airway. When you lose consciousness your head moves spontaneously, obstructing the airway. A device such as a neck support collar may help keep the airway open during sedation. The aim of this study is to assess the effect of a soft neck collar on the airway using an MRI scan.

Who can participate?
Patients aged from 2 to 4 years scheduled for an MRI scan of the brain.

What does the study involve?
Patients were sedated with propofol and underwent MRI scanning of the neck region. The procedure was carried out twice, first with the patient’s head in a neutral position on the MRI table, then with the patient wearing a soft neck collar.

What are the possible benefits and risks of participating?
Not provided at time of registration.

Where is the study run from?
Alexandria Faculty of Medicine (Egypt).

When is the study starting and how long is it expected to run for?
The study ran from December 2012 to December 2013.

Who is funding the study?
Investigator initiated and funded.

Scientific titleEffect of neck collar on upper airway size in children sedated with propofol during magnetic resonance imaging
Study objectivesAssess the effect of a soft neck collar application in children sedated with propofol on the upper airway size and patency using magnetic resonance imaging.
Ethics approval(s)Ethics Committee of the Alexandria Main University Hospitals, 16/6/2011, IRB NO: 00007555-FWA NO:00015712
Health condition(s) or problem(s) studiedPediatric MRI sedation
InterventionPatients were sedated with propofol 1 mg.kg-1, then 50-100 µg.kg-1.min-1. Magnetic resonance images of the neck region, from skull-base down to the subglottic region, were obtained using a dedicated head-neck coil. A three-plane gradient echo scout view was acquired to visualize the gross anatomic details and help to plane for our main sequence, a T1 3D FFE axial sequence extending from the nasopharyngeal roof down to the subglottic region. The sequence was done before and after application of the neck collar. The first head position was determined by MRI to be neutral. The soft neck collar was then applied, maintaining neck extension.
Intervention typeOther
Primary outcome measureUpper airway size measured during the MRI procedure
Secondary outcome measuresIncidence and frequency of complications measured during the procedure and until the patient is fully awake and discharged
