Trial outcomes
Primary outcomes
Emergence agitation
Emergence agitation will be assessed by using Pediatric Anesthesia Emergence Delirium Scale (PAED). The PAED scale consists of 5 criteria that are scored using a 5-point scale. The scores of each criterion are added to make a total score. The maximum achievable score is 20. A score of ≥10 has 64% sensitivity and 86% specificity for the diagnosis of Emergence Agitation (ED). A score of \>12 has 100% sensitivity and 94.5% specificity for the diagnosis of ED.
Secondary outcomes
Perioperative anxiety
Perioperative anxiety which will be measured by using Parental separation anxiety scale (PSAS). PSAS scale: 1. Excellent: Patient unafraid, cooperative, or asleep. 2. Good: Slight fear and or crying, quiet with reassurance. 3. Fair: Moderate fear and crying, not quiet with reassurance. 4. Poor: Crying, need for restraint. Score of 1 or 2 were classified as an acceptable separation, whereas scores of 3 or 4 were considered difficult separations from the parents.
Mask tolerance
Mask tolerance which will be measured by using mask acceptance scale (MAS). MAS score: 1. Excellent: calm, cooperative, or asleep. 2. Good: Moderate fear of the mask Manageable with reassurance. 3. Fair: Cries, combative and needs restraining. 4. Poor: Crying, need for restraint. Score of 1 or 2 were classified as an acceptable mask tolerance, whereas scores of 3 or 4 were considered poor mask tolerance.
Degree of pain
Postoperative pain control will be assessed using Face, Legs, Activity, Cry, Consolability (FLACC) ) on arrival to PACU, 30 minutes, one hour, two hours after surgery and before home discharge. Each category is scored on the 0-2 scale, which results in a total score of 0-10. * 0 = Relaxed and comfortable. * 1-3 = Mild discomfort. * 4-6 = Moderate pain. * 7-10 = Severe discomfort/pain.
Total postoperative analgesics consumption
Total postoperative analgesics consumption will be recorded.
