Effect of Laryngeal Mask Airway on Image Quality n Pediatric Patients Undergoing Magnetic Resonant Imaging: a Randomized Controlled Trial

This study compare the effects of Oral airway vs LMA in preventing anesthesia-induced partial airway obstruction, in an attempt to lessen MRI motion artifacts, which would result in improvements in image quality.

Study Overview

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Magnetic resonance image (MRI) is a frequently used imaging technique especially in oncological patients, where it is used for diagnosis, following up response to treatment and later for detection of possible recurrence. The main problem encountered with MRI is the long time required for completion of the imaging, during which the patient is required to lie still. Patients who are unable to lie still require sedation or general anesthesia (GA). Almost all pediatric patients are uncooperative, making GA, the standard of care for pediatric MRI.

Several general anesthetic techniques including airway management by endotracheal tube & various supraglottic devices (LMA) have been described. Choice of technique by anesthesiologist is influenced by the patient's age, craniofacial and airway anatomy, procedure duration, & illness acuity.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 year to 18 years (ADULT, CHILD)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
ACTIVE_COMPARATOR: Control group
20 patients in which a Guedel oral airway will be inserted for airway management and to conduct inhalational anesthetic through face mask fixed with harness to the head and then connected to anesthesia breathing circuit of MRI compatible anesthesia machine for maintenance of anesthesia of O2 and sevoflurane 2-4% .
Device: guedel airway

Anesthesia will be conducted by induction with 1-2

• Mg/kg of an IV propofol bolus and then anesthesia is maintained with an inhalational anesthesia with sevoflurane 2%-4%. The goal is to maintain the patient spontaneous ventilation throughout the procedure. Monitoring of the patients is done by MRI compatible pulse oximetry for heart rate and oxygen saturation which is connected to MRI control room.

Drug: propofol bolus and then anesthesia sevoflurane
Mg/kg of an IV propofol bolus and then anesthesia is maintained with an inhalational anesthesia with sevoflurane 2%-4%
ACTIVE_COMPARATOR: supraglottic group
20 patients in which supraglottic airway laryngeal mask airway (LMA) will be used and then connected to anesthesia breathing circuit of MRI compatible anesthesia machine for maintenance of anesthesia of O2 and sevoflurane 2-4% .
Drug: propofol bolus and then anesthesia sevoflurane

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Image quality of each MRI sequence
Time Frame: During general anesthesia of MRI investigation procedure
Image quality of each MRI sequence is evaluated by using a scoring system with the following scores: score of 1 (non-diagnostic), score of 2 (poor quality but some diagnostic value), score of 3 (average), score of 4 (good), and score of 5 (excellent).
During general anesthesia of MRI investigation procedure
