A Comparison of the Laryngeal Mask Airway (LMA) Supreme and I-gel in Children

October 1, 2012 updated by: Narasimhan Jagannathan, Ann & Robert H Lurie Children's Hospital of Chicago

A Randomized Trial Comparing the Laryngeal Mask Airway-SupremeTM With the i-gelTM in Children

The aim of this randomized prospective study is to compare two single-use laryngeal mask airways with a provision of a gastric drain tube allowing for evacuation of gastric contents, the i-gel and the LMA Supreme, in pediatric patients undergoing positive pressure ventilation. The investigators hypothesize that airway leak pressures with the i-gel will not be significantly different clinically (higher) when compared with the LMA Supreme.

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

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The goal of this study is to compare the LMA Supreme and i-gel in children having surgery. The investigators hypothesize that airway leak pressures with the i-gel will not be significantly different clinically (higher) when compared with the LMA Supreme. Airway leak pressures will be measured by recording the circuit pressure at which equilibrium is reached. The ease of placement, fiberoptic grade of laryngeal view, feasibility of use during positive pressure ventilation, ease of gastric tube placement, and complications (airway related, gastric insufflation, and trauma) 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.

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.

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: LMA Supreme
Device: LMA Supreme: control device
LMA Supreme will be placed in children weighing 5-50kg based on a computer generated randomization. One of four different sizes of airways will be used: 1.5, 2.0, 2.5, or 3.0. The size of the airway device will be determined according to the manufacturer's guidelines that are standardized by the patient's weight in kilograms.

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
Airway Leak Pressure
Time Frame: Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours
Airway leak pressures will be measured by recording the circuit pressure at which equilibrium is reached when fresh gas flow is delivered at 3L/min when the pressure limiting valve is closed.
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.
