Study summary

We, the investigators at Queen's University, propose to conduct a randomized, double-blind, feasibility trial comparing low-dose ketamine versus fentanyl as adjuncts to Emergency Department procedural sedation with propofol. The outcomes of interest will be safety, with respect to hemodynamic and respiratory adverse effects, as well as efficacy, with respect to adequacy of sedation and analgesia, recovery profiles and patient/physician satisfaction. Our hypothesis, based on a review of existing anesthesia literature, is that low-dose ketamine may be a safer and more efficacious alternative to fentanyl when used as an adjunct to propofol-assisted procedural sedation.

Read the detailed description

This initial, single-centre feasibility study will have the following specific objectives:

  • Comparison of low-dose ketamine with fentanyl as adjunct to propofol-assisted emergency department procedural sedation, with respect to safety and efficacy parameters;
  • Pilot of a blinded emergency department sedation and analgesia protocol, including drug doses, concealment techniques, and data collection tools, to determine the feasibility of a subsequent larger, multi-centre trial;
  • Determination of the true incidence of the primary outcome measures in the study population, using the study drug administration doses and protocol, such that an accurate sample size may be estimated for a future, adequately-powered, multi-centre trial;
  • Validation of a newly-developed ordered, categorical rating scale for the reporting of respiratory and hemodynamic adverse events occurring during emergency department procedural sedation and analgesia.

What researchers measure

Primary outcomes

  1. The primary outcome of interest in this study will be the incidence and severity of adverse events during procedural sedation, characterized by using an ordered, four-point categorical scale of airway, ventilatory and hemodynamic adverse events.

Secondary outcomes

  1. The secondary outcome measures of this study will be: the incidence and type of individual adverse events listed in the primary outcome

  2. the dose of propofol administered during the procedure

  3. times from study drug administration to: beginning of procedure, end of procedure, recovery of appropriate verbal response, Emergency Department discharge, incidence of any adverse event(s)

  4. successful completion of the procedure

  5. the operator's rating of the sedation

  6. incidence of any adverse drug reaction

  7. patient visual analogue scale (VAS) ratings of analgesia, amnesia, and general satisfaction.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 14, 2007, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
