Interventional
Description of intervention(s) / exposure
A prospective, unblinded, randomised controlled trial will be conducted at a metropolitan tertiary-referral teaching hospital ED with an annual census of 70,000. The use of propofol for procedural sedation by emergency physicians or advanced trainees is an established practice in our ED. After administration of analgesia and confirmation of the diagnosis, eligible patients will be invited to participate in the study. Consented participants will then be randomised to the emergency physician-administered (EPA) propofol sedation group or the patient-controlled propofol sedation (PCS) group. The EPA group will receive propofol sedation at the discretion of the treating physician. The PCS group will undergo sedation using a patient-controlled infusion pump containing propofol. An initial bolus of 0.5-0.75mg/kg will be delivered, followed by self-administered increments of 20 mg with a lockout period of 1 minute.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Eligible patients will be identified by their treating doctor. Treatment assignments will be randomised into blocks of four patients with the aid of a random number table. Study instructions, data sheets and treatment arm will be placed in serially-numbered, opaque envelopes for use with consecutive enrolments. This envelop is to be opened only after written consent has been provided by the participant.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Treatment assignments will be randomised into blocks of four patients with the aid of a random number table by an associate not involved in patient enrolment.

Summary
Brief summary
Procedural sedation is frequently used in Emergency Departments (ED) for orthopaedic reductions, cardioversions and other painful but brief procedures. Various pharmacologic agents have been used, including nitrous oxide, ketamine, propofol and combinations of benzodiazepine and opioid. Propofol, a potent, short-acting sedative agent, has gained widespread popularity and has been shown to be safe for procedural sedation in the ED. The advantages of propofol include rapid onset, short duration of action, antiemetic effect and high degree of patient satisfaction. Potential disadvantages include deep sedation, apnoea and hypotension.

Patient controlled sedation (PCS) has been investigated for more than 20 years, primarily for minor procedures in the operating theatre, such as colonoscopy and dental extractions. The potential advantage of the PCS technique is that the patient is able to match their sedation requirement with the noxious stimuli and titrate themselves to an appropriate level of sedation without the risk of over-sedation. A second potential advantage of PCS is the psychological benefit it confers on its user with a sense of control over a stressful and painful procedure. Little data has been published on the use of PCS in the ED setting. The objective of this study is to investigate the efficacy of using propofol in a standard patient-controlled infusion pump for procedural sedation in the ED.
