Trial summary

Patients having Cesarean section after they have been in labor for many hours bleed much more, in average twice as much, as compared with patients having an elective Cesarean section. The investigators believe a simple change in practice might contribute to reduce this bleeding. Read more about this study

About this study

Official title: Comparison of Intravenous Ergonovine With Intramuscular Carboprost, Both in Combination With Oxytocin Infusion, During Cesarean Section for Failure to Progress in Labor: A Double-blinded Placebo-controlled Randomized Controlled Trial

Patients having Cesarean section after they have been in labor for many hours bleed much more, in average twice as much, as compared with patients having an elective Cesarean section. The investigators believe a simple change in practice might contribute to reduce this bleeding. This study will involve the use of oxytocin (also known as syntocinon), ergonovine (also known as ergot) and carboprost (also known as hemabate). Oxytocin is routinely used to help contract the uterus and keep it contracted after the delivery of the baby and placenta, so as to reduce the amount of blood loss. Ergonovine is also given through the intravenous line, while carboprost is given as an injection in the muscle. Although they are not routinely given in every case, these are very frequently given as rescue medications to patients who fail to respond appropriately to oxytocin. This study is designed to determine if ergonovine or carboprost given in association with oxytocin, in a preventive way, after delivery of the baby and placenta, can reduce the amount of blood loss during Cesarean sections following a trial of labour.

Read the detailed description

The objective of the investigators study is to compare the efficacy of intravenous ergonovine and intramuscular carboprost, when administered with oxytocin infusion, prophylactically to decrease blood loss at Cesarean section for labor arrest. Desensitization of the oxytocin receptors has been recently demonstrated in cultured human myometrial cells after continuous and prolonged exposure to oxytocin in-vitro. This could be also the reason for a greater risk of uterine atony and postpartum hemorrhage (PPH) seen in women requiring induction and augmentation of labor. Therefore, addition of a different uterotonic agent, involving a different mechanism of action, to oxytocin infusion is likely to be beneficial, especially in women undergoing CS following failure to progress in labor, who are at a greater risk for PPH.

What is being measured

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

  1. Need for additional uterotonics intraoperatively

    Need for additional uterotonics intraoperatively if requested by the surgeon, YES or NO

    Measured: 1 hour

Secondary outcomes (6)
  1. Effectiveness of uterine contraction

    Adequate/inadequate uterine tone at 3,5 \& 10 min

    Measured: 10 min

  2. Need for blood transfusion

    Any blood products administered

    Measured: 24 hours

  3. Vital signs

    In the OR, heart rate, blood pressure, and oxygen saturation will be measured and looked at for abnormalities

    Measured: 2 hours

  4. Side effects

    The presence of nausea, vomiting,other dysrhythmias, chest pain, headache, bronchospasm and any others will be recorded.

    Measured: 24 hours

  5. Estimated blood loss

    calculated blood loss = EBV (Pre-op Htc-Post-op Htc) EBV (estimated blood volume, mL)=patient's weight in kg x 85

    Measured: 48 hours

  6. Need for additional uterotonics or interventions post-operatively

    Need for additional uterotonics or interventions post-operatively up to 24 hours post-partum

    Measured: 24 hours

Questions about this trial

What is this clinical trial studying?

A study testing Oxytocin, Ergot and Carboprost in people with Postpartum Hemorrhage, run by Samuel Lunenfeld Research Institute, Mount Sinai Hospital at 1 site in Canada.

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 3 inclusion and 6 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 24 Sep 2020. 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.

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?

Need for additional uterotonics intraoperatively (time frame: 1 hour). 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 NCT01869556, 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 24 Sep 2020.
