This is an observational study to see if at birth, flow of blood from a placenta to the baby can be estimated non-invasively using Doppler ultrasound and/or cutaneous perfusion measured using a novel PPG sensor.

Deferred Umbilical Cord Clamping

Study Type: Observational
Study Design: Observational Model: Case Control
Time Perspective: Prospective
Official Title: Delivery Room and Postnatal Assessment of the Physiological Effects of Deferred Cord Clamping on the Newborn: A Feasibility Study

Further study details as provided by University of Nottingham:

Primary Outcome Measures:
  • Quantification of blood flow in the umbilical cord or skin [ Time Frame: For Doppler the umbilical cord will be scanned until it is clamped (up to 3 minutes). Blood flow to the skin will be measured for up to 20 minutes as long as this is not interfering with normal clinical care. ]
    The use of either Doppler ultrasound or a photoplethysmographic (PPG) sensor at delivery to measure either blood flow in the umbilical cord or the skin.

Secondary Outcome Measures:
  • To assess the cardiovascular status of infants undergoing deferred cord clamping in comparison to immediate clamping. [ Time Frame: In the first 3 days after birth. ]
    A number of markers of cardiovascular status will be measured including central and peripheral capillary refill time using a PPG sensor and by the investigators observation, non-invasive blood pressure, heart rate, haemoglobin and haematocrit.

Ages Eligible for Study:   up to 24 Hours   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
The study will recruit babies born at or after 32 weeks with no antenatal or perinatal risk factors that may necessitate the need for resuscitation beyond normal thermal management in the delivery room.

Inclusion Criteria:

  • Greater than ≥ 32 weeks gestation
  • With written informed parental consent

Exclusion Criteria:

  • Antenatally diagnosed problems requiring immediate intervention or problems at delivery are anticipated.
  • No realistic prospect of survival
  • No parental consent
  • Maternal death
  • Non-singleton pregnancies
