Public title
A randomised control trial comparing the timing of the removal of the laryngeal mask airway (LMA) after tonsillectomies in children and the likelihood of delirium occurring on emergence in the post anaesthesia care unit (PACU).

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The intervention will be when to remove the child's LMA after the surgeon has performed the tonsillectomy. Upon consent from the parents for their child to participate in the study, the anaesthetist in charge will be notified by the student when to remove the LMA. This is a randomized procedure with two options: Deep (removing the LMA whilst the child is anaesthetised) or awake (removing the LMA in the PACU upon awakening). Deep removal of the LMA will occur within 2 minutes of completion of tonsillectomy in the operating theatre. The child will be placed in the left lateral position and LMA removed by the attending anaesthetist. In the awake group, the LMA will be removed by the nurse upon the child opening their eyes. Approximately within 20 minutes post tonsillectomy.

The student will take no part in the surgery or induction and maintenance of anaesthesia. Fidelity to the intervention will be monitored by the student who is observing and recording the study.
Intervention code [1] 319837 0
Treatment: Devices
Comparator / control treatment
The study hypothesizes that deep LMA removal in children undergoing tonsillectomy will lower the incidence of emergence delirium in the post-anaesthesia care unit compared to awake LMA removal. Hence our reference group for this study is the awake group.
Control group
Active

Outcomes
Primary outcome [1] 326658 0
Emergence delirium defined as greater than or equal to a score of 10 using the post anaesthesia emergence delirium (PAED) scale.
Timepoint [1] 326658 0
A PAED score will be gathered preoperatively and then 5 minutes and 20 minutes upon awakening postoperatively. Timing will be performed using a stopwatch.
