Trial summary

Using Ketamine for procedural sedation in adults is often uncomfortable for emergency physicians because of the significant proportion of patients experimenting recovery agitation. The investigators believe that combining propofol to ketamine, the proportion of recovery agitation will be significantly lowered. Read more about this study

About this study

Official title: Ketamine-propofol Versus Ketamine Alone for Procedural Sedation in Adults : a Blinded, Randomized Controlled Trial

Using Ketamine for procedural sedation in adults is often uncomfortable for emergency physicians because of the significant proportion of patients experimenting recovery agitation. The investigators believe that combining propofol to ketamine, the proportion of recovery agitation will be significantly lowered.

The objectives of this double-blinded, randomized controlled trial are to compare the proportion of recovery agitation in adults receiving procedural sedation with ketamine-propofol versus ketamine alone, and to compare the proportion of other classical procedural sedation side-effects and parameters such as respiratory depression, hypotension, sedation duration, time of recovery, procedural failures, and levels of satisfaction.

Being tested
Procedural sedation with ketamine-propofol combination, Procedural sedation with ketamine alone

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Procedural sedation with ketamine-propofol combinationDrug

    K= Kétamine P= Propofol RSS= Ramsay Sedation Score

    At t0: 0.5 mg/kg of K (0.1 ml/kg of 5 mg/ml K) followed by 0.5 mg/k of P (0.1 ml/kg of 5 mg/ml P).

    At t0 + 4 min, if needed to obtain an optimal sedation (RSS of 4 or 5): 0.25 mg/kg of K (0.05 ml/kg of 5 mg/ml K) followed by 0.25 mg/kg of P (0.05 ml/kg of 5 mg/ml P).

    At t0 + 8 min, if needed to obtain an optimal sedation (RSS of 4 or 5): 0.25 mg/kg of K (0.05 ml/kg of 5 mg/ml K) followed by 0.25 mg/kg of P (0.05 ml/kg of 5 mg/ml P).

    At t0 + 12 min, if maximal doses have been reached (1 mg/kg of K + 1 mg/kg of P) but the optimal sedation has not been obtained, the procedural sedation will be recorded as a failure in the analysis, and the patient will receive another procedural sedation product (at the discretion of the caregiver).

  • Procedural sedation with ketamine aloneDrug

    K= Ketamine I= Intralipid placebo

    At t0: 1 mg/kg of K (0.1 ml/kg of 10 mg/ml K), followed by 0.1 ml/kg of I (physical placebo of propofol in the other arm).

    At t0 + 4 min, if needed to obtain an optimal sedation (Ramsay Sedation Score of 4 or 5): 0.5 mg/kg of K (0.05 ml/kg of 10 mg/ml K), followed by 0.05 ml/kg of I.

    At t0 + 8 min, if needed to obtain an optimal sedation (Ramsay Sedation Score of 4 or 5): 0.5 mg/kg of K (0.05 ml/kg of 10 mg/ml K), followed by 0.05 ml/kg of I.

    At t0 + 12 min, if maximal doses have been used (2 mg/kg of K) but the optimal sedation has not been obtained, the procedural sedation will be recorded as a failure in the analysis, and the patient will receive another procedural sedation product (at the discretion of the caregiver).

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Proportion of recovery agitation

    Patient will be followed during the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: Recovery agitation is noted after procedural sedation for each patient (30 minutes)

Secondary outcomes (8)
  1. Time from first injection to optimal sedation

    Measured: Patient will be followed during the procedural sedation, for an average time of thirty minutes after the first injection (30 minutes)

  2. Proportion of respiratory depression

    Patient will be followed during the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: respiratory depression is assessed during procedural sedation for each patient (30 minutes)

  3. Proportion of arterial hypotension

    Patient will be followed during the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: Hypotension is assessed during procedural sedation for each patient (30 minutes)

  4. Proportion of vomiting

    Patient will be followed duriong the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: vomiting is assessed after procedural sedation for each patient (30 minutes)

  5. Recovery time

    Patient will be followed duriong the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: Recovery time is assessed after procedural sedation for each patient (30 minutes)

  6. Proportion of procedural failures

    Patient will be followed duriong the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: Procedural failure is noted for each patient if it's happened (30 minutes)

  7. Level of patient's satisfaction

    Patient will be followed during the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: after procedural sedation, patient's satisfaction is recorded (30 minutes)

  8. Level of care giver's satisfaction

    Patient will be followed during the procedural sedation, for an average time of thirty minutes after the first injection

    Measured: after procedural sedation, care giver's satisfaction is recorded (30 minutes)

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Procedural sedation with ketamine-propofol combination and Procedural sedation with ketamine alone in people with Fracture and Dislocation, run by Centre Hospitalier Universitaire de Nice at 1 site in France.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Mar 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Proportion of recovery agitation (time frame: Recovery agitation is noted after procedural sedation for each patient (30 minutes)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01544725, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Mar 2026.
