To evaluate the primary objective of reduced fentanyl use in the post-operative period, the number of fentanyl doses (0.5 mcg/kg IV) administered in the post-operative period prior to discharge will be measured.

The patient's self-reported pain at 30 minutes post-procedure will be measured using a VAS scale. The VAS is a continuous scale made up of a horizontal line, 100 mm in length, anchored by 2 verbal descriptors (No Pain, Worst Possible Pain). The VAS is self-completed by the respondent. The subject is asked to place a line perpendicular to the VAS line at the point that represents their pain intensity. Using a ruler, the score is determined by measuring the distance, in mm, on the 100 mm line between the "No Pain" anchor and the subject's mark. The score would be between 0 and 100. A lower score represents less pain while a higher score represents more pain.

Patient reported pain was evaluated utilizing a visual analog scale (VAS) 30 minutes post-procedure.

To evaluate the secondary objective of pain, the patient's self-reported pain at 60 minutes post-procedure will be measured using a VAS scale. The VAS is a continuous scale made up of a horizontal line, 100 mm in length, anchored by 2 verbal descriptors (No Pain, Worst Possible Pain). The VAS is self-completed by the respondent. The subject is asked to place a line perpendicular to the VAS line at the point that represents their pain intensity. Using a ruler, the score is determined by measuring the distance, in mm, on the 100 mm line between the "No Pain" anchor and the subject's mark. The score would be between 0 and 100.

o evaluate the secondary objective of pain, the patient's self-reported pain at 90 minutes post-procedure will be measured using a VAS scale. The VAS is a continuous scale made up of a horizontal line, 100 mm in length, anchored by 2 verbal descriptors (No Pain, Worst Possible Pain). The VAS is self-completed by the respondent. The subject is asked to place a line perpendicular to the VAS line at the point that represents their pain intensity. Using a ruler, the score is determined by measuring the distance, in mm, on the 100 mm line between the "No Pain" anchor and the subject's mark. The score would be between 0 and 100. A lower score represents less pain while a higher score represents more pain.

Patient reported pain was evaluated utilizing a visual analog scale (VAS) 90 minutes post-procedure.

To evaluate the secondary objective of pain, the patient's self-reported pain at 120 minutes post-procedure will be measured using a VAS scale. The VAS is a continuous scale made up of a horizontal line, 100 mm in length, anchored by 2 verbal descriptors (No Pain, Worst Possible Pain). The VAS is self-completed by the respondent. The subject is asked to place a line perpendicular to the VAS line at the point that represents their pain intensity. Using a ruler, the score is determined by measuring the distance, in mm, on the 100 mm line between the "No Pain" anchor and the subject's mark. The score would be between 0 and 100. A lower score represents less pain while a higher score represents more pain.

Patient reported pain was evaluated utilizing a visual analog scale (VAS) 120 minutes post-procedure.

To evaluate the secondary objective of pain, the time to participant discharge will be measured.

Swallowing will be assessed every 15 minutes following arrival to the recovery room; the time to first swallow will be recorded.

To evaluate the secondary objective of pain, parental satisfaction during the post-operative period will be measured with regards to pain management. The Parental Satisfaction Survey asked the parent to base their response on their child's management from the time they arrive in the recovery room until they were discharged. Question 1 asked "How satisfied were you with your child's pain management at the time of discharge?"

The Parental Satisfaction Survey asked the parent to base their response on their child's management from the time they arrive in the recovery room until they were discharged. Question 2 asked "How satisfied were you with your child's nausea management during the study?"
