Emergence Agitation
Conditions
Brief summary
Pediatric patients undergoing tonsillectomy and adenoidectomy usually have a high incidence of postoperative EA, which increases the risk of developing postoperative airway obstruction and respiratory depression due to anatomical characteristics of operative location and increased susceptibility to opioid analgesics. the study will compare between nebulized and intravenous bolus of dexmedetomidine as a prophylaxis against postanesthetic emergence agitation in children undergoing tonsillectomy, adenoidectomy or adeno-tonsillectomy procedures.
Interventions
Children will receive a nebulized dexmedetomidine 2 mic/ kg diluted in 3 ml of 0.9% saline 1 h before induction of anaesthesia by standard hospital jet nebulizer via a mouthpiece with a continuous flow of 100% oxygen at 6 L /min for 10-15 min. Treatment will be stopped when the nebulizer began to sputter. At end of nebulizer administration, they will be observed for 30 min before induction of general anaesthesia. then the children will be transferred to the operation room and will receive intravenous (IV) normal saline 0.9% in 10 ml volume over 10 minutes after anesthesia induction.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| postoperative Emergence agitation will be evaluated using the Paediatric Anaesthesia Emergence Delirium scale | 60 minutes | Paediatric Anaesthesia Emergence Delirium (PAED) scale will be used to evaluate emergence agitation upon admission to the PACU (0 min, baseline) and at 5, 10, 20, 30, 45, and 60 min until discharge from the PACU. The highest EA scores observed during this period will be recorded. PAED score ≥ 10 will be considered to be a diagnostic endpoint for the development of agitation. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Postoperative pain | 60 minutes | Postoperative pain will be recorded using FLACC scale at 5, 10, 20, 30, 45, and 60 min until discharge from the PACU. |
| emergence agitation (EA) onset | 60 minutes | Emergence agitation onset time was defined as the interval from the extubation to the occurrence. |
| Emergence Agitation duration | 60 minutes | Emergence agitation duration was the time from Emergence agitation onset to its cessation |
