Trial summary

The aim of this randomized prospective study is to compare two laryngeal mask airways with a provision for evacuation of gastric contents, the LMA Proseal and The investigators hypothesize that airway leak pressures with the LMA Proseal will be significantly different (higher) when compared with the LMA Supreme.

About this study

Official title: A Randomized Trial Comparing the Laryngeal Mask Airway-SupremeTM With the Laryngeal Mask Airway-ProsealTM in Children

The aim of this randomized prospective study is to compare two laryngeal mask airways with a provision for evacuation of gastric contents, the LMA Proseal and The investigators hypothesize that airway leak pressures with the LMA Proseal will be significantly different (higher) when compared with the LMA Supreme.

Read the detailed description

The goal of this study is to compare the LMA Proseal and LMA Supreme in children having surgery. The investigators hypothesize that the airway leak pressures with the LMA Proseal will be superior to the LMA Supreme. Airway leak pressures will be measured by recording the circuit pressure at which equilibrium is reached. The ease of placement of the device and gastric tube, fiberoptic grade of laryngeal view, feasibility of use during positive pressure ventilation, and complications (airway related, gastric insufflation, trauma) will also be assessed.

What is being measured

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

  1. Airway Leak Pressure

    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 completely.

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

Secondary outcomes (9)
  1. Time to secure the airway

    From picking up the airway device to bilateral chest expansion and presence of ETCO2

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  2. Number of attempts to place the device

    number of attempts needed for successful placement will be recorded (maximum of 3 attempts will be considered as a failure)

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  3. Fiberoptic grade of laryngeal view

    The laryngeal alignment through the devices will be graded using an established scoring system

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  4. Gastric insufflation

    The presence of gastric insufflations will be assessed during leak pressure testing by using epigastric auscultation

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  5. Ease of gastric tube placement

    The ease of gastric placement will be timed and assessed using a subjective scale

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  6. Fiberoptic view through the gastric tube

    The view through the gastric drain tube of the LMA supreme will be assessed and graded using an established scoring system

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  7. feasibility of positive pressure ventilation

    Peak inspiratory pressure and tidal volumes will be recorded. Maximum peak inspiratory pressure will be the airway leak pressure was determined for each patient

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  8. Quality of the airway

    The quality of hands free anesthesia will be assessed during maintenance of anesthesia using a previously described scale

    Measured: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours

  9. Adverse effects

    complications such as oxygen desaturations, mucosal trauma, reflex activation of the airway, sore throat, dysphonia will be recorded

    Measured: Participants will be followed for the duration of anesthesia and 24 hours postoperatively

Questions about this trial

What is this clinical trial studying?

An observational study of Children, run by Ann & Robert H Lurie Children's Hospital of Chicago 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 3 inclusion and 4 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 12 Dec 2011. 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Airway Leak Pressure (time frame: participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01449656, which also lists 3 linked publications.

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 12 Dec 2011.
