Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study has two intervention arms, one arm will receive 3mg/kg via intramuscular injection and the other arm will receive 4mg/mg via intramuscular injection. Participants will be randomised in a 1:1:1 ratio between the two intervention arms and control. Intramuscular injections will be administered by the treating doctor or nurse. Where adequate sedation to undertake the required procedure is not achieved with the initial intramuscular dose, additional intramuscular or intravenous doses of ketamine will be administered at treating clinician discretion.

Outcomes
Primary outcome [1] 319714 0
The primary outcome of this study is proportion of children who achieve adequate procedural sedation to allow completion of the required procedure with a single needle for the child.

Adequacy of procedural sedation will be measured using the University of Michigan Sedation Scale (UMSS). A score or 3 or greater will be considered adequate procedural sedation.

To reduce bias at least 2 staff will complete the rating of the sedation and will include 2 or more of: the clinician responsible for managing the sedation; the clinician responsible for performing the procedure; and the nurse involved in the procedure.

Secondary outcome [4] 369269 0
Number of needles for patient during the administration of the sedation. For the intravenous arm this will be reported as the number of attempts to achieve IV access.

The number of intramuscular doses will be collected from the medication administration record, the number of intravenous access attempts will be recorded by nursing staff on the study case report form (CRF).

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Randomisation will be web-based and age-stratified. The doctor enrolling the child, after obtaining informed consent, will attend the randomisation webpage, enter the child’s age, and obtain the allocation when the patient is ready for the procedure.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A statistician not directly involved in the analysis of the study results will prepare the randomisation schedule using block randomisation to maintain balance between treatment arms. Treatment allocations to each group will be equal.

Statistical methods / analysis
Data will be analysed by intention-to-treat methods. The statistician will be blinded to route allocation (IV or IM). Baseline descriptive statistics (either mean [standard deviation], median [interquartile range] or n [%] dependent on variable distribution) will be presented for each group and stratum, however following best practice will not be statistically compared.
Chi-squared or Fisher’s exact test will be used to compare rates between the study groups (and by age group where relevant); risk ratios and 95% confidence intervals will be presented for primary and secondary outcomes where appropriate. Continuous data will be analysed using either t-test or Mann-Whitney U test dependent on variable distribution.

Summary
Brief summary
Procedural sedation in children is a commonly performed task in mixed emergency departments around Australia. Ketamine has gained significant acceptance as the drug of choice to conduct this sedation. The preferred route of ketamine administration is an ongoing debate. Historically intravenous ketamine sedation has been favoured, however the evidence is not strong and mostly based on anecdotes. Further, the initial intravenous cannulation required has the negative consequence of inducing significant pain and distress.

Aim
To demonstrate in a randomised control trial that intramuscular ketamine, given in one needle, can achieve successful procedural sedation in children.

Research Design
This is an open label multicentre randomised control trial investigating whether paediatric procedural sedation can be achieved with just one needle. Study sites include Gold Coast University Hospital and Logan Hospital - 537 participants will be enrolled. Patients 1-12 yrs of age presenting to emergency department and requiring procedural sedation with ketamine (as determined by the senior treating clinician) will be eligible for inclusion into the study. Exclusion criteria will include the lack of informed consent and intravenous cannulation being required for another aspect of their management. The study has two intervention arms, one arm will receive 3mg/kg and the other arm will receive 4mg/mg via intramuscular injection. Participants will be randomised in a 1:1:1 ratio between the two intervention arms and control. Intramuscular injections will be administered by the treating doctor or nurse. Where adequate sedation to undertake the required procedure is not achieved with the initial intramuscular dose, additional intramuscular or intravenous doses of ketamine will be administered at treating clinician discretion.. Patients in the control group will be intravenously cannulated and ketamine given initially at 1mg/kg and then dose titrated to effect at the treating clinician’s discretion. The primary outcome will be success of paediatric procedural sedation with only one needle. Secondary outcomes include length of stay in the emergency department, length of sedation and adverse effects in the intramuscular versus intravenous groups.

Significance
This multicentre randomised trial will allow definitive assessment of the efficacy of a one needle approach giving intramuscular ketamine to achieve paediatric procedural sedation in children, with the goal of minimising unnecessary distress.
