Brief Summary

This study aims to compare intranasal dexmedetomidine versus intranasal ketamine as a premedication in children undergoing surgery in our population. Hypothesis is Intranal dexmedetomidine is better than intranasal ketamine in producing preoperative sedation in pediatric patients undergoing surgery under general anesthesia.

Detailed Description

This is a prospective, randomized, double-blind, controlled trial with Minimum 6 months of data collection. Patients will be randomly divided into 2 groups; Group D and Group K with 30 patients in each group. Group D will receive dexmedetomidine 2 mcg/kg intranasal, diluted in normal saline to a total volume of 1 mL and will be administered 0.5 mL per nostril while group K will receive ketamine 2mg/kg intranasal, diluted in normal saline to a total volume of 1 mL similarly divided into two nostrils. The study drugs will be prepared by a second anesthesiologist who will not be involved in subsequent assessments. The calculated dose for each patient will be administered 30 minutes before induction of anesthesia in preoperative holding area in parental/guardian presence. Sedation level will be assessed at 10 minutes interval for the next 30 minutes or until the child will be shifted to the operating room using MOAA/S and ease of parental separation will be scored using PSAS. All patients will be monitored using standard ASA monitoring (ECG, non-invasive blood pressure , pulse oximetry) before induction then every 5 minutes till the end of surgery or a maximum of 1 hour in the operating room. All patients will be induced with 6-8% sevoflurane in 100% oxygen and a 24-G IV access will be secured once the child is asleep. Nalbuphine 0.1 mg/kg IV, atracurium 0.5mg/kg IV (or rocuronium 0.6mg/kg if there's contraindication to atracurium). After endotracheal intubation or laryngeal mask airway (LMA) insertion, all patients will be maintained with 50% O2 in air with isoflurane. Ventilation will be adjusted to maintain an end tidal CO2 concentration between 30-40mmHg. All patients will be given IV paracetamol 20mg/kg as part of multimodal analgesia. If heart rate drops \<70 bpm, atropine 10mcg/kg I/V will be used and hypotension will be treated with IV adrenaline 10mcg/kg. Neuromuscular blockade will be reversed with 50mcg/kg neostigmine and 10mcg/kg glycopyrolate. After regaining regular and spontaneous breathing, the endotracheal tube or LMA will be removed and the child will be shifted to post-anesthesia care unit (PACU).

Primary Outcome Measures
NameTimeMethod
Sedation score as assessed by MOAA/S6 months

Modified Observer's Assessment of Alertness/ Sedation scale (MOAA/S):

6 = Appears alert and awake, responds readily to name spoken in a normal tone 5 = Appears asleep but responds readily to name spoken in a normal tone 4 = Lethargic response to name spoken in a normal tone 3 = Responds only after the name is called loudly or repeatedly 2 = Responds only after mild prodding or shaking

1 = Does not respond to mild prodding or shaking

Secondary Outcome Measures
NameTimeMethod
Ease of parental separation using PSAS6 months

Parental Separation Anxiety Score (PSAS):

1. = Excellent (unafraid, cooperative)

2. = Good (slight fear or crying, easily reassured)

3. = Fair (moderate fear, not quiet with reassurance)

4. = Poor (crying, needing restraint)

Incidence of hypotension and bradycardia in the two groups6 months

Intraoperative hypotension and bradycardia will be monitored before induction then every 5 minutes till the end of surgery or a maximum of 1 hour in the operating room.
