Effects of Milking the Umbilical Cord on Systemic Blood Flow

October 6, 2017 updated by: Anup Katheria, M.D., Sharp HealthCare

A Randomized Controlled Trial of Umbilical Cord Milking Versus Immediate Cord Clamping on Systemic Blood Flow in Premature Infants

Premature babies are at risk for bleeding in their brains, which can result in developmental delays or other neurological problems such as cerebral palsy. Clamping the baby's umbilical cord immediately after birth is standard, but delaying this procedure allows more of the baby's blood to move from the placenta into the baby and prevents head bleeds. However, a delay in clamping the umbilical cord is not usually done in very premature babies, because it would delay their treatment and they could get cold. Milking the umbilical cord is another way to give premature babies more of their own blood while avoiding a delay in treatment. Umbilical cord milking has been shown to improve blood pressure, decrease the need for blood transfusions, and increase the amount of urine made in the first few days of life.

Study Overview

Detailed Description

The aim of this study is to determine whether umbilical cord milking improves blood flow in premature babies, and thereby reduce the occurrence of neurological problems. The investigators predict that the blood flow measured by ultrasounds of the heart will be higher in babies who receive umbilical cord milking compared to those whose cords are clamped immediately. Secondly, the investigators predict that cord milking will improve blood volume, blood pressure, and urine output, and delay the need for blood transfusions.

This will be the first study to look at the effect that umbilical cord milking has on important measures of blood flow, which can predict bleeding in the head and subsequent developmental problems in very premature babies.

  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Umbilical Cord Milking
Umbilical Cord Milking involved milking the umbilical cord at birth.
UCM will be performed by the obstetric team by having the delivering obstetrician hold the infant below the mother's introitus at vaginal delivery or below the level of the incision at cesarean section and having the assistant (the second obstetrician) milk about 20 cm of umbilical cord over 2 seconds and repeating two additional times.
Other Names:
  • stripping the umbilical cord
Active Comparator: Immediate Cord Clamping
Umbilical cord is clamped soon after birth without any milking of the cord.
The umbilical cord will be clamped soon after birth without any milking of the umbilical cord.
Other Names:
  • routine clamping of the umbilical cord

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Superior Vena Cava Flow
Time Frame: 6 hours
Researchers hypothesize that infants who receive umbilical cord milking (UCM) compared to infants who receive immediate cord clamping (ICC) will have higher SVC flow at 6 hours.
6 hours

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Blood Pressure
Time Frame: 6 hours of life
Researchers hypothesize that infants who receive umbilical cord milking (UCM) compared to infants who receive immediate cord clamping (ICC) will have higher blood pressures at 6 hours of life.
6 hours of life
Neurodevelopmental Outcomes
Time Frame: between 18 and 36 months of life
Researchers hypothesize that infants who receive umbilical cord milking (UCM) compared to infants who receive immediate cord clamping (ICC) will have improved neurodevelopmental outcomes. Neurodevelopmental follow-up data including cognitive, language, motor, social-emotional, and adaptive behavior composite scores from the Bayley Scales of Infant and Toddler Development (BSID-III) will be recorded when available. The presence of cerebral palsy, hearing and visual impairment will also be recorded when available.
between 18 and 36 months of life
number of blood transfusions
Time Frame: 36 weeks corrected gestational age
Researchers hypothesize that infants who receive umbilical cord milking (UCM) compared to infants who receive immediate cord clamping (ICC) will have fewer blood transfusions at 36 weeks corrected gestational age.

Superior Vena Cava Flow
Time Frame: 18 hours of life
Researchers hypothesize that infants who receive umbilical cord milking (UCM) compared to infants who receive immediate cord clamping (ICC) will have higher SVC flow at 18 hours.
18 hours of life
Superior Vena Cava Flow
Time Frame: 30 hours of life
Researchers hypothesize that infants who receive umbilical cord milking (UCM) compared to infants who receive immediate cord clamping (ICC) will have higher SVC flow at 30 hours.
30 hours of life
Blood Pressure
Time Frame: at 18 hours of life
Researchers hypothesize that infants who receive umbilical cord milking (UCM) compared to infants who receive immediate cord clamping (ICC) will have higher blood pressures at 18 hours of life.
