Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention Group: Initial dose intravenous ketamine at 0.2mg/kg over 5minutes.
If required, second dose ketamine within 15 minutes at 0.1mg/kg can be given. Morphine or morphine-equivalent opiates may be administered as breakthrough analgesia as boluses as determined by the treating physician.
Intervention code [1] 290855 0
Treatment: Drugs
Comparator / control treatment
Control Group: morphine or morphine-equivalent opiates given intravenously as a bolus at the discretion of the treating physician in relation to each individual participant. the standard of care is that the ED nurses will provide all opiate analgesia
Control group
Active

Outcomes
Primary outcome [1] 293883 0
pain scores: Visual analogue scale will be used to subjectively measure the participants pain.
Timepoint [1] 293883 0
60 minutes post trial initial administration of IV ketamine or opiate
Primary outcome [2] 293884 0
Analgesia requirements (total doses of adjunct and opiate medications).
A review of patient records in retrospective will provide the information of breakthrough analgesia required by all participants.
Timepoint [2] 293884 0
review of analgesia requirement from initial dose of either control or intervention medications through to 72 hours post initial dose.
Secondary outcome [1] 312082 0
Time to reduction of pain (measured on a visual analogue scale every 15 minutes for 60 minutes post intervention)
Timepoint [1] 312082 0
every 15min for 60 minutes
Secondary outcome [2] 312083 0
Patient satisfaction in the short and longer term with analgesia experience in the emergency department. this is a composite outcome.

the follow up questionnaire used to assess this has been specifically designed for this study.
Timepoint [2] 312083 0
from 24 to 72hours post intervention (within this time frame)
this variance is dependent on researcher availability
Secondary outcome [3] 312085 0
Reported adverse effects from study drugs such as:
hypo/hypertension
tachycardia
emergence phenomena
confusion
aggression
hyper-salivation
respiratory depression
nausea
vomiting
These will be objectively and subjectively monitored
Timepoint [3] 312085 0
15 minutely for 1hour post drug administration

adverse effects will be screened at the research follow up from 24 to 72 hours. Or if clinically indicated.

vital signs will be monitored dependent of each individual case, at minimum every 4 hours.
Secondary outcome [4] 312087 0
Impact on emergency department length of stay
This will be reviewed in retrospective through patient records
Timepoint [4] 312087 0
measure the patients ED length of stay, this can be achieved 2-3 days post patient hospital discharge
Secondary outcome [5] 312089 0
Incidence of persistent pain.
Participant questionnaire at 6 and 12 months, this questionnaire was specifically designed for the study.
Timepoint [5] 312089 0
6 and 12 months post intervention
Secondary outcome [6] 312090 0
At the 6 and 12 month follow-up, the participant will be asked to score (from 0-10) their satisfaction with their pain treatment in the ED. "0" being extremely dissatisfied, and "10" being extremely satisfied.
The participant will be asked if they have had a new diagnosis of post traumatic stress disorder or new psychological illness in the past 12 months since the research project.
Timepoint [6] 312090 0
6 and 12 months post medication intervention

Eligibility
Key inclusion criteria
all patients eligible will have to have presented to the emergency department
- Age greater than or equal to18years
- Major traumatic injuries that in the opinion of the treating emergency physician are likely to require high doses of opioid analgesia

Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Known allergy to ketamine or morphine
- Any state (e.g. intoxication) or medical history (e.g. mental health disorder) impairing accurate pain assessment or ability to provide informed consent
- Inability to communicate a pain score/complete follow-up questionnaire (intubation, sedation, altered level of consciousness, major head injury, significant anterograde amnesia, dementia, delirium, significant illness, poor English)
- Administration of ketamine prior to arrival in ED
- Administration of ketamine in the ED prior to patient recruitment (e.g. analgesia, procedural sedation)

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)
Once eligibility is confirmed; clinicians will open a sequentially numbered (randomised number) opaque envelope to reveal the patients allocated treatment group. Treating clinicians will be required to enter patient details onto the envelope prior to opening and obtaining the allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Simple randomisation via an online application. both groups utilised with a catchment group of 100
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s

Efficacy
Statistical methods / analysis
The visual analogue scale has been validated to detect clinically significant differences in pain scores in patients with acute traumatic pain at 13mm (95% CI 10-17mm). Therefore, to detect a clinically significant difference in mean pain scores of 15 mm on the VAS assuming a standard deviation of 25 mm, we would require 44 patients in each group with 80% power with a significance of 0.05%. To allow for attrition and withdrawal we aim to recruit a total of 100 patients to be split evenly between trial groups.
Data will be entered into an excel sheet which would be available for access only to the investigators. Data will be stored in a safe and secure location. Data will be analysed using SPSS 22.0. Continues variables will be tested for normality. Based on the outcome of the test parametric students T test or non-parametric Mann-Whitney test will be carried out to determine the differences in VAS scores. Categorical data will be analysed using the Chi-squared analysis. Bivariate analysis would be performed for determining the confounding factors contributing to ease of pain. A p value < 0.05 will be considered statistically significant.
All data will be analysed on an intention to treat basis. Patients who withdraw or are lost to follow up will be regarded as treatment failures for data analysis purposes and analysed with imputed data.
