Brief summary

The study will compare how often the tubing kinks when a LMA (laryngeal mask airway) with modified retractor is used compared to use of an endotracheal tube (ETT) and non modified retractor is used.

Detailed description

The laryngeal mask airway (LMA)is a device used to secure the airway of patients during general anesthesia. This device is routinely used for anesthesia in elective head and neck surgeries, including adenotonsillectomy. In this study, the efficacy of the LMA will be studied as it pertains to operative times and cost. The child will be randomized into either the LMA group or the ETT group.

Design outcomes

Primary

Measure	Time frame	Description
To determine the number of participants with adverse events with use of LMA and ETT during adenotonsillectomy.	one year	Mouth gag equipment is used for the LMA and the ETT. A modified tongue depressor is used with the LMA and a non-modified tongue depressor is used with the ETT. Data will be collected in regards to the rate of kinking/obstruction of the tubing with each type of equipment to determine which option is the best for use in adenotonsillectomy.

Secondary

Measure	Time frame	Description
To determine total length of procedure and recovery time with use the LMA.	One year	Does the rate of kinking/obstruction of the tubing cause prolonged procedure time and additional issues for anesthesia and the subsequent recovery of the patient.
