Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Presence of Pain	The effect of clonidine on the duration of the analgesia provided by a high volume-low concentration caudal will be measured in the Post Anesthesia Care Unit pain assessments using CHEOPS score every at 0, 30, 60, and 90 minutes after arrival to PACU.; The CHEOPS pain score tool is an observational scale for measuring postoperative pain in children aged 1-7 yrs. The tool includes six categories of pain behavior, each with 3-4 levels and scores range from 4 points (no pain) to 13 points (the worst pain).	24 hours
Primary	Administration of Rescue Pain Medications	Data will be collected and analyzed on the need for rescue pain medications by collecting doses of opioids administered the Post Anesthesia Care Unit.	24 hours
Primary	Time to first Administration of Acetaminophen	24 hours after discharge a phone call interview will be conducted to obtain the time of the first dose of acetaminophen	24 hours
Secondary	Hemodynamic Changes	A change of greater than 20% in heart rate or blood pressure from their baseline established in the preoperative area	24 hours
Secondary	Incidence of Emergence Delirium	The incidence of emergence delirium will be collected utilizing the PAED Scale at 0, 30, 60, and 90 minutes after arrival to the Post Anesthesia Care Unit. The PAED scale will measure the presence of delirium by scoring behaviors from 1-4 (1=calm, 2=not calm but consolable, 3=moderately agitate, restless or not easily calmed, 4=combative, excited, thrashing around)	24 hours
Secondary	Sedation Levels	Measured in PACU utilizing Ramsay Sedation Scale at 0, 30, 60, and 90 minutes after arrival in PACU. The Ramsay sedation scale is a scoring of responses (1-6) [1=anxious or restless, 2=cooperative, oriented, tranquil, 3=responding to commands, 4=brisk response to stimulus, 5=sluggish response to stimulus, 6=no response to stimulus].	24 hours
Secondary	Average Time to Discharge	time of arrival to PACU and discharge time	24 hours
