Study summary

External Cephalic Version (ECV) is a maneuver to modify fetal position in pregnant women with a non-cephalic presentation. Its objective is to achieve a cephalic presentation that allows for vaginal delivery with less risk than a vaginal breech delivery or a cesarean section. ECV is an effective technique to reduce the rate of cesarean sections and is recommended by the Spanish Society of Obstetrics and Gynecology (SEGO) and the World Health Organization (WHO) Cesarean Section Working Group. The WHO aims to reduce interventionism in childbirth globally and implement non-clinical measures to reduce the rate of unnecessary cesarean sections.

Despite Propofol is a sedative agent commonly used by anesthesiologist in countless ambulatory procedures in obstetric anaesthesia, it has been little studied in ECV, and its effect has not been compared with other commonly used agents such as remifentanil or spinal analgesia. The Obstetric Anesthesiology Section of the Spanish Society of Anesthesiology and Resuscitation recommends the use of locoregional analgesia in ECV.

Read the detailed description

This project involves a randomized clinical trial to compare the effect of sedation with propofol versus spinal analgesia in ECV. Therefore, the objectives of this study are:

  • To compare the effect of sedation with Propofol on the success rate of ECV compared to spinal analgesia.
  • To compare the effect of sedation with Propofol on the rate of complications of ECV compared to spinal analgesia.
  • To compare the effect of sedation with Propofol on the length of hospital stay of ECV compared to spinal analgesia.

Locoregional analgesia requires a longer hospital stay than sedation with Propofol and may mask an early diagnosis of complications after ECV, such as placental abruption, which is identified in the initial stages by intense abdominal pain.

Inclusion criteria

  • Voluntary participation.
  • Older than 18 years.
  • Non-cephalic presentation.
  • Desire to attempt a vaginal birth.
  • Normal blood count and coagulation prior to the intervention

Exclusion criteria

Exclusion Criteria:

  • Age under 18 years old.
  • Multiple gestation.
  • Cephalic presentation.
  • Risk of fetal compromise.
  • Unexplained active bleeding.
  • Absolute for vaginal delivery (Placenta Previa)
  • 2 or more previous cesarean sections.
  • Previous myomectomy with entry into the uterine cavity
  • Maternal fever.
  • Thrombocytopenia (\<85,000 ).

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Platelets

Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.

Study arms

  • Experimental
    Sedation with propofol

    Atropine 0.4 mg intravenous bolus and intravenous propofol will be administered through a continuous infusion with a target plasma concentration between 4-6 micrograms/mL maintaining a BIS between 65-75, following the protocol used by Sánchez-Romero J et al. (doi:10.3390/jcm11030489). For this, an intravenous infusion pump (Agilia SP TIVA ES, Fresenius Kabi AG, Bad Homburg, Germany) will be used. After the administration of propofol, a period of 3 minutes will be waited before starting the procedure to ensure the target plasma concentration.

    Drug: Sedation with propofol

  • Active comparator
    bupivacaine

    A combined spinal-epidural anesthesia technique will be performed with a spinal dose of 5-7.5 mg of hyperbaric bupivacaine and 20 μg of intrathecal fentanyl, along with the placement of an epidural catheter, following the protocol used by Brogly N et al. in "Protocols of the Obstetric Anesthesia Section of SEDAR, 2021". After the administration of epidural anesthesia, a period of 3 minutes will be waited before starting the procedure to ensure effective anesthesia.

    Drug: Spinal analgesia with bupivacaine

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jul 2024 (actual). Primary completion is estimated for Oct 2027, 39 months after the start.

Of 119 non-industry interventional studies with no phase under Pregnancy Complications, half reached primary completion within 26 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 48. This study's planned 39 months is above that.

Counting every sponsor, half of 119 studies reached it within 26 months; a quarter within 12 and three quarters within 48.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Nov 21, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
