Association Between Blood Volume, the Interval From Delivery to Cord Clamping, and Number of Umbilical Cord Milking
A study testing cord blood spontaneous drainage and Umbilical cord miking in people with Pregnancy Related and Umbilical Cord Issue, run by Chang Gung Memorial Hospital at 1 site in Taiwan.
Trial summary
Delayed umbilical cord clamping (DCC), usually 1-3 minutes, is reported to be beneficial for term and preterm infants. Nevertheless, there are reasons that urge us to reevaluate the effect of DCC. First, most prior studies were conducted on American and European women. Read more about this study

About this study
Official title: Investigation on the Effects of Delayed Cord Clamping on Maternal and Neonatal Outcomes: Part I. Association Between Blood Volume, the Interval From Delivery to Cord Clamping, and Number of Umbilical Cord Milking
Delayed umbilical cord clamping (DCC), usually 1-3 minutes, is reported to be beneficial for term and preterm infants. Nevertheless, there are reasons that urge us to reevaluate the effect of DCC. First, most prior studies were conducted on American and European women. The benefits of DCC in the infants born to Asian women is not clear. Second, neonates born to Asian mothers usually have lower birth weights and placental weights compared to the neonates and placentas of American and European women. The optimal duration of DCC in Asian women remains undetermined. The objective of this study is to determine the association between the blood volume collected and the interval from delivery to cord clamping and number of umbilical cord milking in women with normal term pregnancies with vaginal delivery or elective cesarean delivery (CS). Results form this study will help us determine the optimal duration of DCC or numbers of cord milking in our population in the following studies.
Read the detailed description
Delayed umbilical cord clamping (DCC), usually 1-3 minutes, is reported to be beneficial for term and preterm infants. In term infants, DCC increases hemoglobin levels at birth and improves iron stores in the first several months of life, which may have a favorable effect on development outcomes. In preterm infants, the benefits of DCC include improved transitional circulation, better establishment of red blood cell volume, decreased need for blood transfusion, and lower incidence of necrotizing enterocolitis and intraventricular hemorrhage. DCC was not associated with increased risk of postpartum hemorrhage or increased blood loss at delivery, nor was it associated with the need for blood transfusion. Three is a small increase in the incidence of jaundice that requires phototherapy in infants undergoing DCC. Given the benefits of most newborns, a number of professional organizations recommends DCC in term and preterm infants, when feasible.
There are reasons that urge us to reevaluate the effect of DCC in our population. First, most prior studies were conducted on American and European women. The benefits of DCC in the infants born to Asian women is not clear. Second, neonates born to Asian mothers usually have lower birth weights and placental weights compared to the neonates and placentas of American and European women. The optimal duration of DCC in Asian women remains undetermined. With the aforementioned reasons, the investigators will conduct a study to clarify the effects of DCC and umbilical cord milking on maternal and neonatal outcomes in Taiwanese women. Our objective is to determine the association between the blood volume collected and the interval from delivery to cord clamping and number of umbilical cord milking in women with normal term pregnancies with vaginal delivery or elective cesarean delivery (CS);.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
cord blood spontaneous drainageProcedure or surgery
In women allocated to groups of cord blood spontaneous drainage, two clamps will placed at 4 finger breadths from the infant's abdomen and cut between two clamps after delivery of the baby. The clamp on the placental site will be removed and the drainage time and amount of cord blood to a measuring glass will be recored.
Umbilical cord mikingProcedure or surgery
In women allocated to groups of cord milking group, two clamps will placed at 4 finger breadths from the newborn's abdomen and cut between two clamps immediately after delivery of the baby. The clamp on the placental site will be removed, then the umbilical cord will be squeezed several times, 5 seconds between each squeezing, to collect cord blood in a measuring glass. The number of cord milking and the volume of blood collected will be recorded.

Participants will be randomized into 4 groups: group 1, vaginal delivery with cord blood spontaneous drainage; group 2, vaginal delivery with cord milking; group 3, CS with cord blood spontaneous drainage; group 4, CS with cord milking. In women allocated to groups of cord blood spontaneous drainage, two clamps will placed at 4 finger breadths from the infant's abdomen and cut between two clamps. The newborns will be taken care by the nurse after delivery. The clamp on the placenta site will be removed and record the drainage time and amount of cord blood to a measuring glass. In women allocated to groups of cord milking group, the umbilical cord will be squeezed several times, 5 seconds between each squeezing, to collect cord blood after delivery. The number of cord milking and the volume of blood collected will be recorded.

Questions about this trial
What is this clinical trial studying?
A study testing cord blood spontaneous drainage and Umbilical cord miking in people with Pregnancy Related and Umbilical Cord Issue, run by Chang Gung Memorial Hospital at 1 site in Taiwan.
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 2 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 7 Jul 2021. 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 Taiwan. 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?
Blood volume (time frame: delivery of the baby). 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 NCT04898868, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
