A Comparison of the LMA Unique and LMA Supreme in Children
An observational study of Children, run by Ann & Robert H Lurie Children's Hospital of Chicago at 1 site in United States.
Trial summary
The goal of this study is to compare the LMA Unique and LMA Supreme in children having surgery. We hypothesize that the airway leak pressures with the LMA Supreme will be superior to the LMA Unique. Airway leak pressures will be measured by recording the circuit pressure at which equilibrium is reached. Read more about this study

About this study
Official title: A Prospective, Randomized Comparison of the LMA Unique and LMA Supreme in Children
The goal of this study is to compare the LMA Unique and LMA Supreme in children having surgery. We hypothesize that the airway leak pressures with the LMA Supreme will be superior to the LMA Unique. 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, and complications (airway related, gastric insufflation, trauma) will also be assessed.
Read the detailed description
The LMA Supreme is a newer version of the current model, the laryngeal mask airway Unique. Both models are approved for use by the FDA, and are routinely used for airway management during general anesthesia. Three main features distinguish the laryngeal mask airway Supreme from the original LMA: i) a curved rigid airway tube, ii) provision for a gastric drain tube, and iii) a larger mask for improved fit and airway seal.
The aim of this randomized prospective study is to compare two types of the laryngeal mask airway: the laryngeal mask airway Unique and the laryngeal mask airway Supreme, in pediatric patients without the use of neuromuscular blockade. Based on the design features listed above, we hypothesize that the airway leak pressures with the LMA Supreme will be superior to the LMA Unique. 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, 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.
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: after placement of the supraglottic airway device/ Participants will be followed 24 hours postoperatively
Secondary outcomes (8)
Fiberoptic grade of laryngeal view
The laryngeal alignment through the devices will be graded using an established scoring system
Measured: After placement of the supraglottic device
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 24 hours postoperatively
Time to secure the airway
From picking up the airway device to bilateral chest expansion and presence of ETCO2
Measured: after placement of the supraglottic airway device
Number of attempts to place the device
number of attempts needed for successful placement will be recorde (maximum of 3 attempts will be considered as a failure)
Measured: at the beginning of anesthesia
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: After placement of the LMA supreme
Ease of gastric tube placement
The ease of gastric placement will be assessed using a subjective scale
Measured: After placement of the LMA supreme
Gastric insufflation
The presence of gastric insufflations will be assessed during leak pressure testing by using epigastric auscultation
Measured: During leak pressure testing
Quality of the airway
The quality of hands free anesthesia will be assessed during maintenance of anesthesia using a previously described scale
Measured: During maintenance of anesthesia

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: after placement of the supraglottic airway device/ Participants will be followed 24 hours postoperatively). 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 NCT01409785, which also lists 4 linked publications.
