Interventional
Description of intervention(s) / exposure
A. Normal saline 10ml bolus over two minutes is placebo and then Metoclopramide Intravenous Infusion (MII): Metoclopramide 20mg in 100ml of Normal Saline as intravenous infusion over 15 minutes, is intervention.

B. Metoclopramide Intravenous Bolus (MIB): Metoclopramide 20mg as 10ml bolus over 2 minutes intravenously, is the control treatment, and an infusion of Normal Saline over 15 minutes, is placebo.

Outcomes
Primary outcome [1] 2389 0
The rate of drug induced akathisia (DIA) as measured by a patient derived global outcome measure and the Prince Henry Hospital Akathisia Rating Scale (PHARS).
Timepoint [1] 2389 0
Measured at 15 minutes after infusion, then every 15 minutes for an hour. If akathisia occurs in this time it is a negative outcome.
Secondary outcome [1] 4154 0
The severity of DIA as measured by a patient derived global outcome measure and PHARS.
Timepoint [1] 4154 0
Outcomes measured at fifteen minutes after infusion, then every 15 minutes for one hour.
Secondary outcome [2] 4155 0
The degree of distress resulting from DIA as measured by a patient derived global score.
Timepoint [2] 4155 0
Outcomes measured at fifteen minutes after infusion, then every 15 minutes for one hour.

Can healthy volunteers participate?
No
Key exclusion criteria
Evidence of pre-existing akathisia or previous DIA, patients who are unstable or too unwell to participate, Parkinson disease, restless leg syndrome, taking of dopamine antagonist drugs such as tricyclic anti-depressants (TCA), antiemetic or antipsychotic in the preceding 24 hours and those in whom akathisia rescue medication would be contra indicated, such as glaucoma or urinary retention. Patients with cognitive impairment or English as a second language.

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)
Pharmacy will receive the randomisation list from the researcher and keep it in a secure place. The clinician enrols a subject and gets their consent. Pharmacy will confirm completed enrolment and consent forms and the subjects are allocated to intervention A or B using the randomisation list. This will ensure that the sequence was concealed until allocation has occurred. Pharmacy will then prepare identical appearing infusion and bolus drugs and placebo labelled A or B in sealed unmarked container and give it to the clinician to administer. The after-hours nurse coordinator will perform this role using pre-prepared pharmacy packs in non-pharmacy hours.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A permute block method will be used to ensure equal number in both intervention groups. This will be done using the Moses-Oakford method for treatment assignment that has been previously described. Group codes of A-MII and B-MIB arbitrary block allocation would be performed to allocate to two intervention groups. A list of random numbers would be obtained from a random number chart. After recording the random numbers a final block order and thus randomisation list would be produced.

Summary
Brief summary
Metoclopramide is a frequently used drug in emergency departments. It can cause unpleasant side effects called akathisia. We are trying to find out if giving the metoclopramide slowly makes getting akathisia less likely.
