Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Preoperatively, all patients will be assessed by detailed medical and surgical history, complete clinical examination and routine laboratory investigations and will be allocated randomly into two groups; Group I (intranasal ketamine group = 45 children): Children of this group will receive ketamine intranasal in a dose 5 mg/kg.
Group II (Intranasal dexmedetomidine group = 45 children): Children of this group will receive dexmedetomidine intranasal in a dose 1 microgram/kg.
A preoperative fasting period of 6 hours. No premedication will be taken.
Induction of general anesthesia will done 15 minutes after study drug administration with sevoflurane which will be titrated with increments of 1% at each breath up to 8% in oxygen 100%. Once an appropriate depth of anesthesia will be obtained an IV cannula and a suitable laryngeal mask will be inserted (its position will be confirmed by capnography) and sevoflurane concentration will be reduced to an end tidal concentration of 3% in 100% oxygen. Spontaneous breathing will be allowed provided ETCO2 remained below 50 mm Hg; if ETCO2 exceeded 50 mm Hg, the patient will be excluded from the study and ventilation will be assisted. No muscle relaxant or narcotic will be administered during the procedure. The patients will be monitored continuously for heart rate, oxygen saturation, respiratory rate, end tidal CO2 and mean arterial blood pressure. Sevoflurane will be discontinued immediately after insertion of the T-tube, and the laryngeal mask will be removed 60 seconds later and the patient will be transported to the post-anesthesia care unit (PACU) in a quiet and warm environment without any stimulus. Parents will be allowed to be at the child’s bedside in the PACU.

Outcomes
Primary outcome [1] 297898 0
The incidence of EA was evaluated using Aono's four point scale 1= calm; 2= not calm but could be easily consoled; 3= moderately agitated or restless and not easily calmed; 4= combative, excited, or disoriented, thrashing around. Scores of three and four will be considered as presence of EA, while one and two as absence of EA.
Timepoint [1] 297898 0
5 minutes after awakening
Primary outcome [2] 297908 0
The pediatric anesthesia emergence delirium (PAED) scale will be used to evaluate the severity of EA , a five-point rating scale (eye contact, purposeful actions, awareness of surroundings, restlessness and consolability), with five grades(0 to 4) for each item. The total score (20) is the sum of the scores of the individual items. The severity of EA increases proportional to the total score. A score = 10 will be considered agitated, and will be treated with i.v propofol 1 mg/kg as rescue medication. A score = 15 reflects severe agitation while, scores less than 10 means no agitation.
Timepoint [2] 297908 0
The severity of EA will be evaluated at Time 0 , 5, 10, 15 and 30 min after awakening .
Secondary outcome [1] 322591 0
Duration of emergence in minutes
Timepoint [1] 322591 0
The time interval from switching off sevoflurane to spontaneous eye opening, the ability to obey commands after and purposeful movements .
Secondary outcome [2] 322593 0
Occurrence of complications: e.g. nausea, vomiting, bradycardia, Cough, laryngospasm, or desaturation (SpO2 below 95%), or any other complication will be treated , recorded and cleared to the ethical committee on time.
Timepoint [2] 322593 0
from the time of drug administration till 30 minutes after awakening
Secondary outcome [3] 322594 0
The response to parental separation will be assessed using parental separation anxiety scale; excellent (1):child cooperative, unafraid or asleep. Good (2): the child is slightly afraid/crying and quiet with reassurance. Fair (3): the child is moderately afraid and no response to reassurance. Poor (4): the child is crying and needs restraint .
Timepoint [3] 322594 0
15 minutes after drug administration
Secondary outcome [4] 322596 0
The response to face mask induction will be evaluated using the mask acceptance scale; 1= combative, crying, 2= not easily calmed, moderate fear of mask, 3 = cooperative with reassurance, 4 = cooperative and calm .
Timepoint [4] 322596 0
at the time of induction of anesthesia
