Comparison of LMA-Fastrach and I-gel for Blind Tracheal Intubation.

August 2, 2017 updated by: Centre hospitalier de l'Université de Montréal (CHUM)

The investigators aim to compare two different types of supraglottic devices for tracheal intubation in patients undergoing elective surgery under general anesthesia.

Our hypothesis is that the use of the I-gel supraglottic airway will result in a higher first attempt success rate of blind tracheal intubation.

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

Supraglottic airway devices such as LMA-Fastrach and I-gel provide patent airways during general anesthesia.

The LMA-Fastrach is designed to provide a conduit for blind or fiberoptically guided tracheal intubations. However, the success rate of tracheal intubation on the first attempt through this device varies between 50 and 87%.

The I-gel is a newer device for airway management which, with its wide bore, allows direct passage of a tracheal tube. Recent studies suggest that the I-gel is easy to insert and that limited experience is needed before a high success insertion rate is obtained.

In this prospective and randomized study, we will evaluate the performance of both devices for tracheal intubation in patients undergoing elective surgery under general anesthesia.

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

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

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
Time Frame

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.
