Outcomes
Primary outcome [1] 293091 0
Time to sedation as defined by a sedation score of less than or equal to 2 on a 6 point scale (6=highly agitated & violent, 0=asleep)
Timepoint [1] 293091 0
Time to adequate sedation
Secondary outcome [1] 310317 0
Need for re-sedation <60 minutes after achieving sedation (‘rescue’ drug requirement). Resedation will be required if the patient again becomse acutely agitated and is a danger to themsleves of others.
Timepoint [1] 310317 0
within 60 minutes of achieving adequate sedation initially
Secondary outcome [2] 310318 0
Adverse events including airway obstruction, hypoventilation, oxygen desaturation (<90%), hypotension (<90mmHg), movement disorders (eg. dystonic reactions, twitching), seizures, vomiting or aspiration. All events are assessed clinically (observation) or with stadard equipment (sphygmomanometer, saturation probe)
Timepoint [2] 310318 0
within 60 minutes of achieving adequate sedation initially

65 Years
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
1. known hypersensitivity or contraindication to the study drugs

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)
Patients requiring sedation will be determined by Emergency Physicians or Registrars. The next sequential study pack will be assigned to the patient. The study pack will contain the drugs randomly assigned to the patient. All drugs will be blinded.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
computer generated random numbers
Masking / blinding
