Study type
Interventional
Description of intervention(s) / exposure
Nitrous oxide (N2O) plus intranasal fentanyl (INF) treatment group
This treatment requires a Nurse Practitioner, Registrar or consultant physician.
Patients randomised to this group will be given INF 2 µg/kg via laryngeal mask airway (LMA) Intranasal mucosal atomization device 15 mins prior to the procedure. Inhalation N2O will commence via a Matrix Digital mobile device management (MDM) delivery mixer starting at 50% N2O and titrated to a concentration of 70% N2O over 5 mins prior to procedure. This slow titration of N2O decreases the incidence of vomiting using N2O in combination with INF.

Ketamine procedural sedation and analgesia (PSA) treatment group
For the ketamine sedation a consultant physician, or registrar under the direction of a consultant physician, will be present at the bed side for the procedural sedation.
Patients randomised to receive ketamine for PSA will receive an initial dose of 1 to 2 mg/kg IV Ketamine prior to commencement of the procedure. Dose of ketamine provided will be decided by clinician discretion. Topical EMLA (lidocaine 2.5% and prilocaine 2.5%) will be used at the site of injection at least 30 mins prior to IV cannulation to reduce pain at the injection site. Subsequent titrated doses of IV ketamine (0.3 to 0.5 mg/kg) may be administered during the procedure, as deemed necessary by the administering clinician.

Outcomes
Primary outcome [1] 319305 0
The primary outcome of this study will be parental satisfaction with the procedure between treatment groups, measured using a scale from 0 (= very bad) to 10 (= excellent).
Timepoint [1] 319305 0
Following the conformation X-ray
Primary outcome [2] 319386 0
Overall judgement on the child’s experience will be further assessed using a validated, satisfaction questionnaire adapted to the ED setting (Iacobucci T et al., 2005). This questionnaire investigates several areas: quality of care provided by the clinical staff involved in the procedure, parental opinion of the child’s recollection and parental opinion of the overall experience. Satisfaction is a score of 6 or above on the Likert scale.

Secondary outcome [1] 367658 0
The child’s perception of their pain experienced during the procedure will be assessed using a modified Visual Analogue Scale (VAS) with faces and a scale from 0 (= no pain) to 10 (= worst pain).
Timepoint [1] 367658 0
At ED discharge
Secondary outcome [2] 369095 0
Child behaviour prior to and during the procedure will be assessed using the Face, Legs, Activity, Cry, Consolability (FLACC) score

Prior to and during the procedure
Secondary outcome [3] 369096 0
The Modified Observer’s Assessment of Alertness scale will be used to evaluate the level of sedation
Timepoint [3] 369096 0
Level of sedation will be recorded at regular intervals throughout the treatment.
Secondary outcome [4] 369097 0
An economic evaluation of staffing costs associated with both treatment methods will be undertaken.
Timepoint [4] 369097 0
Treating staff will be documented on the data collection sheet.
Secondary outcome [5] 369144 0
Patient length of stay will be used to perform an economic evaluation of each treatment
Timepoint [5] 369144 0
Time stamps will be taken throughout the patients stay in ED
Secondary outcome [6] 369145 0
Success of the procedure will be assessed by asking the clinician if the reduction achieved is adequate for patient disposition from ED.
Timepoint [6] 369145 0
Following the conformation X-ray
Secondary outcome [7] 369146 0
Any sedation-related adverse events requiring medical intervention to correct deranged physiology, resulting abandonment of the procedure, requiring a prolonged ED admission or an unplanned admission to hospital will be recorded in accordance with the consensus panel on sedation research of both the Pediatric Emergency Research Canada (PERC) and the Pediatric Emergency Care Applied Research Network (PECARN)
Timepoint [7] 369146 0
Throughout patient stay in ED

Summary
Brief summary
The most commonly employed paeidtric procedural analgosedatives (PAS) over the past few decades have been both nitrous oxide (N2O) and ketamine. This is a prospective randomised comparison trial comparing inhaled N2O plus INF to IV ketamine for paediatric patients requiring PAS for fracture reduction. We hypothesis that N2O plus INF is equivalent to ketamine regarding overall procedural analgosedative efficacy for the patient in addition to being more cost-effective given the quicker offset of action and consequent shorter length of stay plus the requirement for fewer and less specialised medical personnel.
