Overview
Brief Summary
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.
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.

Outcomes
Primary Outcomes
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.
Secondary Outcomes
- Time to secure the airway(Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours)
- Number of attempts to place the device(Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours)
- Fiberoptic grade of laryngeal view(Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours)
- Gastric insufflation(Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours)
- Ease of gastric tube placement(Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours)
- Feasibility of positive pressure ventilation(Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours)
- Quality of the airway(Participants will be followed for the duration of anesthesia and after surgery, an expected average of 12 hours)
- Incidence of device repositioning and/or replacement(Participants will be followed for the duration of anesthesia and after surgery, an average of 24 hours)
- Oropharyngolaryngeal morbidity at discharge(Participants will be followed for the duration of anesthesia and after surgery, an average of 24 hours)
- Oropharyngolaryngeal morbidity at 24 hours post-operatively(Measured at 24 hours after device placement/study initiation)
