About this study

Official title: A Randomized Controlled Trial Comparing the ProSeal Laryngeal Mask Airway With the Laryngeal Mask Airway Supreme in Mechanically Ventilated Patients

Laryngeal mask airway is a widely used device in routine anesthesia for airway management during surgery. It consists of a tube with an inflatable cuff that is inserted into the mouth after induction of general anesthesia. The Proseal Laryngeal mask airway and the Laryngeal mask airway Supreme are two variants of the Laryngeal mask airway. The laryngeal mask airway Supreme is a newer version of the laryngeal mask airway.

The research is being done to compare two variants of the laryngeal mask airway: the Proseal laryngeal mask airway and the Laryngeal mask airway Supreme. This study will determine if the newer model, the Laryngeal mask airway Supreme, is easier to insert and is better positioned than the older model, the Proseal laryngeal mask airway. Both models are approved for use by the FDA, and are routinely used to assure the airway during general anesthesia.

Being tested
Supreme Laryngeal mask airway, Proseal laryngeal mask airway
Keywords

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Supreme Laryngeal mask airwayDevice

    Supreme Laryngeal mask airway is a new, single use laryngeal mask airway variant

  • Proseal laryngeal mask airwayDevice

    Proseal is a multiple use, variant of the laryngeal mask airway

Study groups in NCT00836095
Study groupRoleWhat they receive
Supreme LMAOtherSupreme Laryngeal mask airway is a new, single use laryngeal mask airway variant. The choice of the airway device will be randomized by opening a sealed envelope immediately before induction. The airway device will be blindly inserted by an experienced attending anesthesiologist.
Receives: Device: Supreme Laryngeal mask airway
Proseal LMAActive comparatorProseal is a multiple use, variant of the laryngeal mask airway. The choice of the airway device will be randomized by opening a sealed envelope immediately before induction. The airway device will be blindly inserted by an experienced attending anesthesiologist.
Receives: Device: Proseal laryngeal mask airway

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Insertion Time

    The insertion time will be the measured time that it takes the anesthesiologist to insert the airway and verify ventilation of the patient's airway. Data reported will be time in seconds ± the standard deviation.

    Measured: During intubation of the patient

Secondary outcomes (1)
  1. Insertion Success Rate

    Insertion success rate will be reported as the number of patients for whom the airway device was successfully inserted and ventilation was verified.

    Measured: During intubation of the patient

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Supreme Laryngeal mask airway and Proseal laryngeal mask airway in people with Adverse Effect of Unspecified General Anesthetics, run by Milton S. Hershey Medical Center at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 8 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 15 Apr 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 3 Jun 2014). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Insertion Time (time frame: During intubation of the patient). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 15 Apr 2016.
