October 22, 2014 updated by: Narasimhan Jagannathan, Ann & Robert H Lurie Children's Hospital of Chicago

A Randomized Comparison of the I-gel and Air-Q as Conduits for Fiberoptic-guided Tracheal Intubation in Children

The purpose of this study is to determine if there is a difference in time for successful fiberoptic guided tracheal intubation through the i-gel or air-Q supraglottic airway.

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

The goal of this randomized study is to evaluate the efficacy of the i-gel as a conduit for fiberoptic tracheal intubation when compared to the air-Q in children. Intubations will be performed by residents in training. The primary outcome is of time for successful tracheal intubation. The investigators hypothesize that residents will intubate the trachea faster when using the air-Q as compared to the i-gel. The ease of placement of the supraglottic airway device, fiberoptic grade of laryngeal view, time for device removal after intubation, and peri-operative complications will also be assessed.

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.

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.
Experimental: air-Q
Patients will receive the air-Q with size based on manufacturer recommendations of body weight
Device: air-Q
Patients randomized to this intervention will have the air-Q placed following induction of general anesthesia. Subsequent tracheal intubation will be performed using the device as a conduit for fiberoptic-guided intubation. Following successful tracheal intubation, the device will be removed.
Experimental: i-gel
Patients will receive the i-gel with size based on manufacturer recommendations of body weight
Device: i-gel
Patients randomized to this intervention will have the i-gel placed following induction of general anesthesia. Subsequent tracheal intubation will be performed using the device as a conduit for fiberoptic-guided intubation. Following successful tracheal intubation, the device will be removed.

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
Time to Successful Tracheal Intubation
Time Frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Time to successful tracheal intubation when using fiberoptic bronchoscopy to intubate through the i-gel or air-Q ILA. Three separate times will be measured by an independent observer: 1) Time to first glottic view: defined as the duration of time ending with the first view of the glottic opening. 2) Time to carinal view: defined as the duration of time ending with visualization of the carina. 3) Time to successful tracheal intubation: defined as the duration of time ending with the observation of a square wave end-tidal capnogram after successful tracheal intubation
participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
