About this study

Study aim to evaluate the efficacy and safety of a novel technique of UTERINE COOLING during repeated cesarean section (CS) in reducing blood loss, and record any adverse effects following it.

Read the detailed description

Bleeding during vaginal or operative delivery is always of prime concern. Despite significant progress in obstetric care 125,000 women die from obstetric hemorrhage annually in the world.

The incidence of caesarean delivery is increasing, and the average blood loss during caesarean delivery (1000 mL) is double the amount lost during vaginal delivery (500 mL).

Caesarean section (CS) rate as high as 25-30% in many areas of the world. In Egypt the CS rate is 27.6 %, in United States of America, from 1970-2009 the CS rate rose from 4.5-32.9%, and declined to 32.8% of all deliveries at 2010. In spite of the various measures to prevent blood loss during and after caesarean section, post-partum hemorrhage (PPH) continues to be the most common complication seen in almost 20% of the cases, and causes approximately 25% of maternal deaths worldwide, leading to increased maternal morbidity and mortality. Indeed we need to reduce the bleeding during and after caesarean sections aiming for reducing the morbidity and mortality rate due to obstetric hemorrhage, which can be life threatening.

The hematocrit level falls by 10% and blood transfusion is required in 6% of women undergoing caesarean delivery versus 4% of women who have a vaginal birth. Numerous methods for performing caesarean section exist targeting a safe delivery for the infant with minimum maternal morbidity. Operative morbidity includes hemorrhage, anemia, and blood products transfusion may be required associated with many risks and complications.

Women who undergo a caesarean delivery are much more likely to be delivered by a repeat operation in subsequent pregnancies. For women undergoing subsequent cesarean, the maternal risks are even greater like massive obstetric hemorrhage, hysterectomy, admission to an intensive care unit, or maternal death. Medications, such as oxytocin, misoprostol and prostaglandin F2α, have been used to control bleeding postoperatively.

The uterus is a smooth muscle whose contraction is modulated most directly by intrinsic or extrinsic oxytocin. During pregnancy the spiral arteries within the uterus and beneath the placenta enlarge to provide adequate perfusion to the placenta. After separation of the placenta the uterine smooth muscle cells contract in a pincer-like action to pinch the spiral arteries closed. When uterine contraction is inadequate (approximately 4-6% of normal pregnancies) the spiral arteries continue to bleed. If not addressed the bleeding can be excessive, even leading to maternal death. Approximately 5-8 out of 1,000 cesarean sections require hysterectomy to control bleeding.

Release of calcium ions from sarcoplasmic reticulum stores is the immediateinitiator of contraction, and calcium's diffusion from the muscle filaments andre-uptake by the sarcoplasmic reticulum results in relaxation of contraction. Insome smooth muscles cold enhances contraction; perhaps by slowing the re-uptake of calcium.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Uterine Cooling TechniqueProcedure or surgery

    Also called Hetta-UCT

    Standard LSCS will be done except immediatelyfollowing delivery of the fetus the uterus will beexternalized in the usual fashion and the body of theuterus cephalad to the hysterotomy incision will bewrapped in sterile surgical towels saturated in sterile,iced normal saline. These towels will come from asterile cooling pot set to 30 degrees Fahrenheit. Theskin of the abdomen will be draped to prevent contactwith the cold towels. Iced saline-soaked towels will bekept in place for a minimum of 5 minutes and replacedat the discretion of the attending obstetrician until thehysterotomy is closed and the uterus is replaced intothe patient's abdomen.

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 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 9 Apr 2019. 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 Egypt. 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?

Intra-operative Blood Loss (ml) (time frame: 20 minutes). The study lists 2 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 NCT03793153, which also lists 19 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 9 Apr 2019.
