About this study
Official title: Capnography as an Adjunct to Standard Monitoring During Midazolam and Propofol Sedation for Colonoscopy
In the study the value of capnography for avoiding complications during sedation for colonoscopy is evaluated.
Read the detailed description
In this randomized controlled trial the utility of capnography gets evaluated. Hypoxemia may occur during sedation with midazolam and propofol. Whether hypoxemia may be prevented by an additional capnographic monitoring is subject of the study.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Capnography in people with Hypoxemia and Complications, run by Technical University of Munich at 3 sites in Germany.
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 4 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 3 Feb 2011. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 3 sites in Germany. 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 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
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?
Hypoxemia (time frame: From the start to the end of colonoscopy, i.e. from 0 h to approximately 2 h). 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 NCT01072487, 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 3 Feb 2011.
