A Phase 4 study testing Manual titration of propofol in people with Colonoscopy (Ambulatory Patients), run by Brugmann University Hospital at 1 site in Belgium.
Trial summary
Deep sedation with propofol for ambulatory colonoscopy has become standard clinical practice.To achieve the necessary (e.g.: no excessive movement and no awareness) level of sedation during colonoscopy, propofol can be titrated by hand, continuous infusion or by target controlled infusion.

About this study
Official title: A Psychomotor Recuperation Study After Deep Sedation for Colonoscopy Between Target Controlled and Manual Titration of Propofol.
Deep sedation with propofol for ambulatory colonoscopy has become standard clinical practice.To achieve the necessary (e.g.: no excessive movement and no awareness) level of sedation during colonoscopy, propofol can be titrated by hand, continuous infusion or by target controlled infusion.
The aim of the investigators is to evaluate sedation efficacy and recovery between two groups of ambulatory patients having a colonoscopy: one group will receive a manual titration of propofol, the other group a target controlled infusion (TCI) of propofol. The investigators will evaluate both groups before, during and after colonoscopy for adverse events, quality of sedation and recovery. When patients are estimated to be ready for discharge, they will also be subjected to a cognitive and a psychomotoricity test.
Read the detailed description
Deep sedation with propofol for ambulatory colonoscopy has become standard clinical practice. Fewer adverse events and a faster wake up time than with the use of benzodiazepines are proven. A growing group of patients are subjected to this examination for diagnostic and screening purposes.
In most cases, patients can return home after a short recovery time, under the supervision of an accompanying person. Often, no residual effects are clinically detectable. Some studies advocate that driving skills recover quickly. Current guidelines however, insist to avoid driving or using public transportation alone for at least 12 hours (24 hours if other sedatives are used).
To achieve the necessary (e.g.: no excessive movement and no awareness) level of sedation during colonoscopy, propofol can be titrated by hand, continuous infusion or by target controlled infusion. Only one study, to the investigators knowledge, compares efficacy between manual titration and target controlled infusion of propofol in combination with fentanyl for bidirectional endoscopy.
The aim of the investigators is to evaluate sedation efficacy and recovery between two groups of ambulatory patients having a colonoscopy: one group will receive a manual titration of propofol, the other group a target controlled infusion (TCI) of propofol. The investigators will evaluate both groups before, during and after colonoscopy for adverse events, quality of sedation and recovery. When patients are estimated to be ready for discharge, they will also be subjected to a cognitive and a psychomotoricity test.
To evaluate cognitive function, the investigators will use the digit symbol substitution test. The digit symbol substitution test is popular for detecting deterioration in concentration. Here for 90 seconds, a test subject is asked to change a number in a symbol.
As psychomotor test, the investigators chose a choice reaction time test for its sensitivity to detect minor changes after propofol sedation. This test has also validity in alcohol intoxication. A simple reaction time test is also included for its easy applicability and obtainability in everyday practive. Test results will be compared to see if there is a correlation with the choice reaction time tests.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Manual titration of propofolDrug
One group will be sedated with a manual titration technique: here the titration of propofol is done manually by the anesthetist. Dosages may range between 50 and 400mg, given by boluses of 20-50mg.
Target controlled infusion of propofolDrug
The other group will be sedated with a target controlled infusion technique (pump, marsh or Schneider). The anesthetist can titrate indirectly by adjusting the target controlled infusion to achieve adequate sedation. The concentrations of propofol may vary between 2 and 6 µg/ml, achieved by increments of 0.5-1.5 µg/ml.
| Study group | Role | What they receive |
|---|---|---|
| Propofol (manual titration) | Experimental | Not described Receives: Drug: Manual titration of propofol |
| Propofol (target controlled infusion) | Active comparator | Not described Receives: Drug: Target controlled infusion of propofol |
What is being measured
The primary outcome is the main question the study is designed to answer.
Digit Symbol Substitution test score
The digit symbol substitution test score wil be compared between the propofol manual titration and the propofol target controled infusion groups. This test will evaluate cognitive function.
Measured: 24 hours
PADS score
Time and fitness to discharge will be evaluated with the PADS score. This will be done at discharge of the patient, after the colonoscopy.
Measured: 24 hours
Choice reaction time test score
The choice reaction time test score will be compared between the propofol manual titration and the propofol target controlled infusion groups. The groups will be tested before the colonoscopy and every 10 minutes after waking up, up to the discharge of the patient. This test is used to evaluate the psychomotoricity of the patients.
Measured: 24 hours

The digit symbol substitution test score wil be compared between the propofol manual titration and the propofol target controled infusion groups. This test will evaluate cognitive function.

Time and fitness to discharge will be evaluated with the PADS score. This will be done at discharge of the patient, after the colonoscopy.
Choice reaction time test score

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing Manual titration of propofol in people with Colonoscopy (Ambulatory Patients), run by Brugmann University Hospital at 1 site in Belgium.
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 19 Jul 2022. 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 Belgium. 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?
Digit Symbol Substitution test score (time frame: 24 hours). The study lists 3 primary outcomes in all. 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 NCT02314559, which also lists 12 linked publications.
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 19 Jul 2022.
