Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
There will be two intervention groups: One group will be randomised to receive dexmedetomidine preoperatively 45 minutes prior to theatre (2 micrograms/kg made up to 1 mL with saline intranasally) and then after induction of anaesthesia they will receive an infusion of saline (1mL/kg) over ten minutes intravenously. The other group will receive a 1mL saline nasal spray 45 minutes prior to theatre and then after induction of anaesthesia they will receive a dexmedetomidine infusion 1mL/kg of 1microgram/mL solution over ten minutes intravenously. The nurse administering the premedication and the anaesthetist administering the infusion will be blinded to group allocation and the solutions will be made to look identical by a clinical trials pharmacist. The timing of administration will be recorded on the medication chart of the patient to monitor adherence.

Outcomes
Primary outcome [1] 297137 0
Negative behaviours as measured by the Post Hospitalisation Behaviour Questionnaire for Ambulatory Surgery. This validated instrument is an 11 item parental report measure. It will be administered by a researcher to a parent via telephone interview on day 3, 14 and 28 post procedure.
Timepoint [1] 297137 0
Day 3, 14 and 28 post procedure
Primary outcome [2] 297138 0
Negative behaviours as measured by the Strength and Difficulties Questionnaire. This is a validated behaviour screening tool for children aged 2 to 16. It has 25 items on 5 scales and will be administered by a researcher to a parent via telephone interview on day 3, 14 and 28 post procedure.
Timepoint [2] 297138 0
Day 3, 14 and 28 post procedure
Secondary outcome [1] 320133 0
Emergence delirium. This will be measured using the Cornell Assessment of Paediatric Delirium (CAP-D). This scale has been designed to detect hypoactive, hyperactive and mixed delirium in children.
Timepoint [1] 320133 0
Immediately post procedure
Secondary outcome [2] 320134 0
Adverse effects. Common adverse effects of dexmedetomidine include bradycardia and hypotension. These will be assessed and recorded by the recovery nurse by the pulse rate on the pulse oximeter and non-invasive blood pressure measurement.
Timepoint [2] 320134 0
Immediately post procedure
Secondary outcome [3] 320135 0
Pain in recovery. This will be assessed using the Faces, Legs, Activity, Cry, Consolability (FLACC) Scale by the recovery nurse. This validated pain measurement tool is commonly used for children aged 2 months to 7 years.
Timepoint [3] 320135 0
Immediately post procedure
Secondary outcome [4] 320136 0
Analgesic requirements in recovery. The recovery nurse will record any analgesia given on the post-operative medication chart.
Timepoint [4] 320136 0
From arrival in the recovery room until discharge to the day ward.
Secondary outcome [5] 320137 0
Time in recovery. The arrival and departure times from recovery are recorded on the hospital theatre computer system.
Timepoint [5] 320137 0
From arrival in the recovery room until discharge to the day ward.
Secondary outcome [6] 320138 0
Pain at home. This will be assessed by a numeric rating scale (NRS) where a researcher will ask a parent via telephone which whole number from 0 to 10 best reflects the intensity of their child's pain with 0 being no pain and 10 the worst pain imaginable.
Timepoint [6] 320138 0
Day 3, 14 and 28
Secondary outcome [7] 320139 0
Parental days off work. A researcher will ask the parents about any days off work taken to care for their child via telephone interview.
Timepoint [7] 320139 0
Day 3, 14 and 28
Secondary outcome [8] 320140 0
General practitioner visits. A researcher will ask parents about any GP visits via telephone interview.
Timepoint [8] 320140 0
Day 3, 14 and 28
Secondary outcome [9] 320141 0
Parental satisfaction. This will be assessed by a researcher asking a parent via telephone interview to rate their overall satisfaction with their child's anaesthetic on a 5 -point Likert scale.
Timepoint [9] 320141 0
Day 3, 14 and 28

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
The researcher who determines eligibility and obtains consent will be unaware of group allocation. Randomistaion will be performed in a 1:1:1 ratio and allocation concealment will be via the use of sequentially numbered, sealed opaque envelopes prepared by a third party.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be generated by a randomisation application that uses a computer generated sequence allocation.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Efficacy
Statistical methods / analysis
Baseline characteristics will be compared using student’s t-test for continuous variables and chi-squared analysis for categorical variables.

The chi-squared test will be used to compare changes in proportion of NBC over time.

Stepwise multiple binary logistic regression will be used to analyse relationships between baseline characteristics and NBC. Only independent predictor variables will be retained in the final model.

The sample size was calculated assuming an underlying rate of 50% of negative behaviour change on day 3 post procedure and a clinically significant reduction would be 50% to an overall rate of 25%. For a power of 90%, an alpha-error of 0.05 and assuming a 20% loss to follow-up we would need 98 patients per group.
