This study aims to compare the efficacy of using oral Melatonin versus nebulized Dexmedetomidine in limitation of emergence agitation in children undergoing adenotonsillectomy.
Adenotonsillectomy is one of the most commonly performed surgical procedures in children with high incidence of emergence agitation about 80% and high degree of post operative pain. Oral midazolam, a short-acting benzodiazepine, is commonly used as a standard premedication in children due to its well-established anxiolytic, sedative, and amnestic effects. It works by enhancing GABAergic neurotransmission in the central nervous system, helping reduce anxiety and facilitating a smoother anesthetic induction and emergence. Dexmedetomidine is a centrally acting α-2 adrenergic agonist with sedative, hypnotic, analgesic, anxiolytic, anti-sialagogue, antinociceptive and sympatholytic action.

RECRUITINGEmergence 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.
Time frame: 30 minutes after recovery
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.
Time frame: During transferring to operating room (Up to 30 minutes).
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.
Time frame: Intraoperatively
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.
