About this study
Official title: Comparison of Two Doses of Carbetocin for Prevention of Uterine Atony During Elective Cesarean Section: a Randomized Controlled Trial
The purpose of this study is to evaluate the effectiveness of two doses of carbetocin (50 mcg vs 100 mcg) in preventing uterine atony during elective cesarean section.
Read the detailed description
Postpartum hemorrhage is a major cause of mortality and morbidity in the world, and it is most often caused by uterine atony. To prevent this complication, uterotonic medication is used during elective cesarean section.
Carbetocin, a long-acting synthetic analogue of oxytocin, has been used for this purpose for many years. This medication has numerous side effects: hypotension, tachycardia, nausea, vomiting, chest pain, etc. Using a smaller dose of carbetocin might lower the incidence of these side effects, without compromising prevention of uterine atony in a low-risk group of patient.

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 5 inclusion and 11 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 29 May 2013. 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 Canada. 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?
Utilization of a second uterotonic drug (time frame: First 48 hours of the postpartum). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 29 May 2013; AzTrials last refreshed its copy on 8 Nov 2026.
